Description

ANTIB ACTERIAL AGENTS

Field of the Invention

This invention relates to antibacterial agents having a quinazolindione core structure, processes for their preparation, and methods for their use.

Background of the Invention

Antibiotic resistance is a worldwide problem with catastrophic potential. A Task Force co-chaired by the United States Centers for Disease Control (CDC), Food and Drug Administration (FDA), and National Institutes of Health (NIH) recently addressed this important issue, observing that drug resistant pathogens are a growing menace to all people, regardless of race, age, gender, or socioeconomic background. The Task Force noted that a number of microbes responsible for infections in humans are rapidly developing resistance to existing drugs. For example, according to the Task Force, in the United States alone, up to 30 percent of the Staphylococcus pneumoniae infections (skin, bone, lung, and bloodstream infections) are no longer susceptible to penicillin in some areas. Up to 11 percent of S. pneumoniae are resistant to third generation cephalosporin antibiotics. Significantly, resistance of S. pneumoniae to the fluoroquinolones, a newer class of potent antibiotics, has also been reported.

Exemplified by ciprofloxacin A, the fluoroquinolones are bacterial inhibitors that apparently exert their effect by inhibiting bacterial DNA gyrase and topoisomerase IV.

A

The consequences of antibiotic resistance, particularly fluoroquinolone resistance, can be fatal for some individuals. In a case reported from Denmark, a 62-year-old woman diagnosed with food poisoning from ciprofloxacin-resistant Salmonella died after undergoing antibiotic treatment using that drug.

The dramatic and lethal emergence of antibiotic resistance typified by this and other reports has spurred the U.S. Task Force to call for the implementation of a public health action plan to combat antimicrobial resistance. As a vital component of that plan, there is a need for the development of new products that will prevent the continued emergence of antibiotic resistance generally, and that will prevent and treat colonization and infection of resistant organisms in patients.

Representative compounds of the present invention, which are encompassed by Formula 2- VIII include, but are not limited to the compounds in Table 2- VIII and their pharmaceutically acceptable acid or base addition salts, or amide or prodrugs thereof.

Illustrations of typical preparations of compounds of the present invention having Formula I are shown in the following synthetic schemes. Typical heterocyclic and aromatic side chains defined by R5 in Formula I are prepared as are also described. All of the 3-hydridoquinazolinediones of the invention may be prepared from appropriately substituted benzoic acid starting materials. Protecting groups (referred to in the schemes as "Pro") may be used when appropriate throughout many of the schemes. Although specifically noted in certain schemes, the appropriate use and choice of protecting groups is well-known by those skilled in the art, and is not limited to the specific illustrations shown below. It should also be understood that such protecting groups not only serve to protect chemically reactive sites, but also to enhance solubility or otherwise change physical properties of the underlying invention compound. A number of general reactions such as oxidations and reductions are not shown in detail in the schemes, but can be carried out by standard methods well-known to those skilled in the art. In general, the starting materials used in the following schemes are obtained from commercial sources, or are readily prepared by standard methods. All cited published articles, patents, books, and the like are incorporated herein by reference. The following Schemes are organized in two parts. The first part summarizes synthetic approaches to the core structures represented by compounds of Formulas I- VIII, depicted generally by the reference structure in the following drawing. The second part summarizes synthetic approaches to the preparation of particular R₅ groups that can be attached to the core structures. The meaning of "core structure" and "sidechain" is demonstrated in the following drawing by structure X. As will be seen below, there are two general approaches to preparing compounds of the present invention. In the first general approach, the core structure is prepared and then the R sidechain is attached to the core structure to provide a compound of the invention. In the second general approach, the R₅ sidechain is attached to a precursor of the core structure and then the core structure is prepared by intramolecular cyclization. Both approaches are disclosed in the following section.

Reference Structure

Core Structure

Core Structures

The core structures of the compounds of the invention can be prepared from appropriately substituted benzoic acid derivatives. Thus compounds of formula I wherein J is C or N, K is C, and R₆ is C C₇ alkyl or substituted alkyl can be prepared as summarized in Scheme 1, wherein the

and R₅ sidechain are attached subsequent to cyclization to form the dione ring. Thus, the anthranilic acid derivative can be converted to the corresponding alkoxy benzamide ester. The amide can be treated with a carbon monoxide equivalent such as phosgene to provide the 3-N-methoxy quinazolinedione derivative. Deprotonation of the position 1 amide moiety in the dione, followed by alkylation using an alkylating agent such as RjX, wherein

has any of the meanings provided herein, can give rise to the R_\ alkylated quinazolinedione derivative. An R₅ sidechain can be attached to quinazolinedione core structure using base or a palladium catalyst according to methods available to the skilled artisan. Finally, the 3-methoxy group can be removed by hydrogenation to provide the 3-hydridoquinazolinedione compound. Scheme 1

Scheme 2 provides a particular example of this approach. Thus, upon treatment with carbonyl diimidazole and O-methylhydroxy amine, 4,5- difluoroanthranilic acid can be converted to the N-methoxy benzamide derivative. Upon treatment with phosgene, the N-methoxy benzamide derivative undergoes cyclization to provide methoxyquinazolinedione. Alkylation of at the 1 -position using bromomethylcyclopropane in the presence of base affords the Ri substituted compound. Coupling of an amine at the R₅ position provides the R₅ coupled compound, which can be converted to the 3-hydrido compound under hydrogenation conditions.

Scheme 2-A provides an alternative approach to quinazolinedione ring formation. Urea formation at the nitrogen of the cyclopropylamine moiety in the starting compound can be effected using chlorosulfonyl isocyanate. Heating of the urea in refluxing toluene, followed by removal of the protecting group, gives the invention compound. Scheme 2-A

ate

A characteristic of the approach outlined in Schemes 1, 2, and 2-A is the generation of the 3-hydrido group subsequent to the introduction of the R₅ sidechain. Scheme 3 provides an alternative approach to compounds of the invention wherein J is N or C, and wherein the R₅ sidechain is attached subsequent to the generation of 3-hydrido group. Thus, the nicotinic acid derivative can be converted to the nicotinamide derivative via an acid chloride or acid anhydride intermediate. The acid chloride or anhydride intermediate can be converted to a urea deriviative upon treatment with oxalyl chloride or an equivalent, followed by addition of RιNH₂, wherein R_\ has any of the meanings provided herein. Cyclization of the urea can occur upon treatment of the compound with base in the presence or absence of a chelating agent, to provide a quinazolinedione. An R₅ sidechain can be attached to the dione as provided in Scheme 2. Sche e 3

Scheme 4 provides a particular approach to invention compounds wherein R₅ is aryl. Thus, the acid is treated with acid and methanol to provide the methyl ester. Conversion to the R₅ aminated compound occurs using using benzyl amine in the presence of triethylamine and DMSO. Removal of the benzyl group using Pd/C provides the R₅ primary amine. The ester moiety is then saponified to the acid, and the R₅ amine is converted to a bromide using CuBr and t-BuNO₂. Conversion of the acid moiety to an amide, followed by generation of the acyl isocyanate and treatment with cyclopropylamine (R]NH₂) provides the urea, which is treated with base as provided in Scheme 2-A to give a quinazolinedione with an R₅ bromo group. An aryl group can be coupled at the Rs-position using an aryl stannane in the presence of a palladium catalyst under conditions known to those skilled in the art to provide a compound of the invention.

Scheme 5 provides another variation of this approach wherein R₅ is iodo. Attachment of an iodo group at the R₅-position can be effected via diazotization of the R₅ amine in the starting compound using isoamyl nitrite in the presence of Cul. Saponification of the ester moiety, followed by the series of transformations provided earlier can provide the R₅ iodo quinazolinedione compound. Attachment of an aryl, alkyl, or heterocycloalkyl group to the R₅-position of the compound can be achieved using procedures available to those skilled in the art. Scheme 5

Scheme 6 provides an approach to invention compounds wherein R₆ is a fluorinated alkyl group. Thus, treatment of 2,4,5 trifluorobenzoic acid with lithium hexamethyldisilylazide and dimethyl formamide gives the R₆ aldehyde, which, when treated with (diethylamino) sulfur trifluoride (DAST) gives the R_ό difluoromethyl compound. Ring closure to provide the quinazolinedione scaffold is achieved as provided in earlier schemes.

3) (diethylamino)sulfur trifluoride

Scheme 7 provides an approach to compounds of the invention wherein R₅ is a substituted cyclopropyl group. The para position in ethyl (2,4,5 trifluoro-3- methyl) benzoate is activated relative to the ortho or meta position. Thus, reaction of the starting compound with the shown cyano ester in the presence of base provides the para addition product. Saponification of the t-butyl ester, followed by decarboxylation under acidic conditions provides the R₅ cyanomethyl compound. Treatment of the R₅ cyanomethyl compound with benzyl triethyl ammonium chloride and 1 ,2 dibromethane gives the R₅ cyanopropyl compound. Quinazolinedione formation then occurs via cyclization upon treatment with base to provide the target compound.

Scheme 7

Schemes 8A-C provide approaches to invention compounds wherein R₆ is an alkoxy group and J may be N or C. Scheme 8-A summarizes the general approach. Esterification of the meta-hydroxy benzoic acid derivative, followed by O-alkylation of the meta-hydroxy group using the t-butyl ester of bromoacetic acid provides the shown aryl ether. Hydrolysis of the t-butyl ester, followed by fluorination gives the fluoromethoxy compound. Quinazolinedione ring formation can be effected as provided in earlier schemes.

Scheme 8-B provides a particular example of the Scheme 8A approach. In this variant, fluorination is effected using xenon difluoride (XeF ) in a chlorinated solvent (Shaw, et. al, J. Am. Chem. Soc. 91, 1563 (1969).

Scheme 8-B

Scheme 8-C provides an approach to the synthesis of an invention compound with an R₆ difluoroalkoxy group. Thus, 2,4 difluoro-3-methoxy benzoic acid is converted to the amide. The methoxy group is then converted to a phenol using boron tribromide. O-alkylation of the phenol with dichlorodifluoromethane in the presence of base, followed by hydrogentaion, provides the difluoromethoxy compound. Formation of the quinazolinedione ring scaffold can then be achieved as provided earlier. Scheme 8-C

Scheme 9 provides an approach to the synthesis of tricyclic invention compounds. Thus, the indole starting material can be converted to the shown methyl ester using standard procedures. Removal of the thioethyl group using Raney Nickel is followed by reduction of the indole double bond using trifluoroacetic acid/triethyl silane to provide the cyclization precursor. Treatment of the cyclization precursor with trifluoroacetic acid and potassium isocyanate in a chlorinated solvent gives the tricyclic invention compound. Sche e 9

Scheme 10 provides an approach to compounds of the invention wherein R₃ is alkyl or alkoxy as defined herein. Thus, a compound wherein R₃ is H and R₆ is alkyl or alkoxy can be treated with a base, such as lithium diisopropyl amide (although other bases may be used), followed by an alkylating or acylating agent. Alkylating agents (such as alkyl halides, -mesylates, triflates, and the like) and acylating agents (such as acid halides, acid anhydrides, phosphoryl halides, and sulfonyl halides, among others) are well known in the art and many are commercially available, for instance from a supplier such as Aldrich, and are listed in the Aldrich Handbook of Fine Chemicals, 2002-2003. Other alkylating or acylating agents can be prepared as needed according to methods available to the skilled artisan. An R₅ sidechain can then be attached to the resulting compound wherein R₃ is an alkyl, acyl, or other group.

Scheme 10

R₃= H R₃= E R₅= F R₅= F R₆= C C₆ alkyl, 0(C_rC₆ alkyl) R₆= C_rC₆ alkyl, 0(C C₆ alkyl)

Other approaches to the preparation of the invention compounds are available to the skilled artisan. For example, a general synthetic strategy for core formation suggested by WO 01/53273, which is assigned to the same assignee as the instant application, can be substantially modified and adapted to the synthesis of the invention compounds disclosed herein. Thus, Scheme 11 discloses another approach to the invention compounds wherein the Riand R₅ sidechains are attached prior to cyclization to form the quinazolinedione ring. As provided by the scheme, a difluoro substituted benzoic acid wherein one or both of J or K may be N is reacted with oxalyl chloride or an equivalent acylating reagent (such as an acid anhydride), and the acid halide or anhydride is reacted with an alcohol (ZOH) to afford the respective ester (Z is Ci-Cg alkyl such as methyl, ethyl, isopropyl, etc.). The ester is reacted with an amine, for example, a heterocyclic amine, to produce the desired 4-heterocycIic phenyl derivative. Alternatively, carbocycles and aryls may also be introduced at this 4-position using palladium catalyzed couplings of tin or boronate carbocycles and aryls, with starting materials containing a Br, I, or triflate at the 4-position as described by Suzuki A., Pure Appl. Chem. , 1994;66(2):213-222 and Stille J.K., Angew. Chem. 1986;98(6):504-519.

Reaction of the 2-fluoro benzoic acid analog with a primary amine RjNH2 affords the corresponding anthranilic acid ester. The ester group is readily hydrolyzed by reaction with an acid such as hydrochloric acid or a base such as sodium hydroxide to give the corresponding polysubstituted anthranilic acid. The acid is then coupled to a source of NH₃, typically protected by a protecting group (Pro), to provide the corresponding amide. The amide may then undergo cyclization in the presence of a carbon monoxide equivalent such as phosgene to provide the quinazolinedione. At this point, the protecting group may be removed to give the 3-hydridoquinazolinedione of Formula I, which may be a final product of the invention, or may be further derivatized. The protecting group (Pro) of the N-protected quinazolinedione is removed by conventional methods such as hydrogenation, treatment with acid, lewis acid, or base, or metal catalysis to afford the shown invention compound A.

If R3 is a leaving group such as F, it may be activated towards displacement with a nucleophile HY-Pro' where Y is NH or O. Other R3 groups such as chlorine, bromine, or sulfonyl are also good leaving groups. The displacement generally is carried out in a solvent such as ethanol, DMSO, DMF, THF, and at a temperature of about 0°C to 120°C.

The protecting groups (Pro and Pro') may be selectively removed by hydrogenation, acid or base treatment, metal catalysis, or other standard methods. When Pro or Pro' is methoxy or benzyl, either of these groups may be removed with Pd/C and hydrogen. A t-butyl oxycarbonyl group may be removed by alcoholic HC1, TFA, or TFA in dichloromethane, ethyl acetate or diethyl ether. Allylic oxycarbonyl groups may be removed by PhSiH3 and Pd catalyst. Solvents such as alcohol, THF, alcohol/THF, alcohol/THF/DMF, diethyl ether, etc. are generally employed in such protecting group cleavage reactions.

B A In Scheme 12, an ortfto-aminobenzoic acid wherein one or both of J or K may be N is utilized as the starting material, and is alkylated on the amino group. For example, when R] is cyclopropyl, the alkylation is carried out according to the method of Gillaspy (Tetrahedon Letters, 1995:7399) to provide the cyclopropyl amine. When R] is phenyl or substituted phenyl, the respective amine is prepared from the rt jo-fluorobenzoic acid using a base, such as, lithium di isopropyl amide or lithium hexamethyl disilazide, and the appropriate aryl amine

(R1NH2). When R] is any alkyl group, such as t-butyl or isopropyl, the R\ can be introduced by reacting the amine and ortho halo benzoic acid with a Cu catalyst such as copper bronze, or cuprous acetate in the presence of a base such as potassium acetate, triethylamine, or pyridine.

The resulting R\ -substituted amino benzoic acid is then coupled to ammonia in an appropriately protected form to provide the corresponding benzamide using methods described in the literature. The corresponding amide can be further reacted, if R5 is a leaving group such as fluoro, with various heterocyclic amines (e.g., piperidine or pyrrolidine) to form the desired 4-heterocyclic benzamide derivative. Alternatively, carbocycles and aryls (e.g., cyclobutyl or phenyl) may also be introduced at this 4-position using palladium catalyzed couplings of tin or boronate carbocycles and aryls, if the starting material contains a Br, I, or triflate at the 4-position.

The 4-substituted benzamide derivative is then cyclized to generate the quinazolinedione by reaction with carbonyldiimidazole (CDI), phosgene, triphosgene or the like in ethereal solvents such as diethyl ether, chlorinated hydrocarbons such as dichloromethane, or aromatic hydrocarbons such as toluene, in the presence of a base such as triethylamine or sodium bicarbonate (NaHCO3).

Alternatively, the corresponding amide is first cyclized and then the R5 halo group is displaced by reaction with a carbocyclic amine to afford the same product. Deprotection by conventional methods provides the invention compound A. Scheme 12

Scheme 13 illustrates alkylation at the 1 -position of a quinazolinedione to provide invention compounds wherein R] is alkyl. Thus, a 2-aminobenzoic acid wherein one or both of J or K may be N is reacted with an N-protected amine to provide the corresponding N-protected amide. This intermediate can then be reacted with a carbon monoxide equivalent such as phosgene or phosgene/base in an ethereal solvent, or with a phosgene equivalent such as triphosgene in a chlorinated hydrocarbon such as dichloromethane, to give the quinazolinedione. The alkylation of the quinazolinedione to provide a 1-alkylated-quinazolinedione is accomplished by reaction with an alkyl halide as described by Bouzard, supra., 1990. Typically, such reactions are carried out in THF, ether, DMSO, an alkanol, or DMF, and in the presence of a base. Typical alkyl halides (RjX where X is halo) include ethyl iodide, ethyl bromide, cyclopropyl iodide, n-decyl bromide, and the like. Typical bases include sodium hydride, potassium carbonate, and the like. Conversion of the 1-alkylated-quinazolinedione to other invention compounds (and removal of protecting groups such as benzyl) can be carried out as provided earlier to give the corresponding 1 -alkyl (R\ = alkyl) 3-hydrido compounds such as A.

Scheme 13

Displacement of leaving groups located at the Rs-position of the quinazolinedione (e.g., R5 = halo) as shown above is not limited to nitrogen heterocycles. Other nucleophiles (Nu) such as CH3O-, N3-, R'R"NH, R'-NH^ and R'S- (where R' and R" are each independently (C_rC )alkyl) also displace a leaving group such as F, CI, or NO2 at the R₅-position as provided in earlier schemes. When the leaving group is a triflate or higher halide (Br or I), organotin reagents or organoboronates may be used with palladium catalysts to deliver a carbon nucleophile. The methodology generally disclosed in Scheme 14 may be adapted to follow the coupling methodology of Stille et al., Angew. Chem. Int. Ed. Eng., 1986;25:508, further exemplified by Mitchell (Synthesis, 1992:803). It is to be understood that in Scheme 14, one or both of J or K may be N.

Scheme 14

Deprotection

All of the chemistry depicted and described in Schemes 11 to 14 is applicable to make compounds of Formula I wherein J and K both are carbon, or where one or both of J and K are N. When either J or K is nitrogen, the displacement reactions described above may be even more facile than when J and K are both carbon.

As stated above, compounds of Formula I wherein one or both of J or K are nitrogen may be prepared by Schemes 11-14, or alternatively, by routes which take advantage of the activation of leaving groups ortho and para to the J and/or K nitrogen atom. Such routes will systematically introduce R5 and R] groups as desired. This methodology also applies to cases in Formula I where K-Rg is C-H or C-F and J-R4 is C-F. Such systematic substitutions are illustrated in

Scheme 15.

For example, a pyridine amide has leaving groups such as halo on both sides of the nitrogen. Such groups are generally CI, but Br, I, F, alkylthio, and sulfoxides, such as methyl sulfoxides, are also good leaving groups for such compounds. These leaving groups may be sequentially displaced based on reactivity. In Scheme 15, where J = N or J-R4 = CF, the 4-chloro (para to the aminocarbonyl group) is displaced preferentially (relative to the 2-chloro group) using a nucleophilic amine such as diefhylamine, pyrrolidine, methylpiperazine, and the like to give the corresponding amino substituted analog. This analog can then undergo reaction with R1NH2 to displace the second leaving group (e.g., the

2-chloro group). The resulting 2,6-disubstituted-pyridylamide is then reacted with carbonyl diimidazole (CDI), phosgene, or other carbon monoxide equivalents to form the cyclized quinazolinedione product.

Scheme 15

Tricyclic compounds (i.e., where R] and Rg in Formula I are taken together with the atoms to which they are attached to form a ring) can be prepared according to Schemes 16-19. Schemes 16-19 differ in the introduction of the R_] substitutions in Structures B and C wherein R₅ is as defined above for Formula I. In Scheme 16, the ortho-fluoro nitro compound (other leaving groups such as chlorine, bromine, and sulfonyl may also be employed in place of fluoro) undergoes reaction with the shown ester. The nitro group is then reduced using, for example, Raney Ni, H2 over Pd/C, or an active metal in acid such as iron or tin in HC1 or acetic acid. The newly formed amine readily cyclizes with the ester (other acid analogs may be employed such as thioesters, amides, and the like). The cyclized product is then reduced with hydride reducing agents such as UAIH4 and the like to produce the dihydroquinoline derivative, which in turn is reacted with chloral hydrate and then an acid to form a dione ring. The dione ring is subsequently opened using, for example, sodium hydroxide and hydrogen peroxide to give the benzoic acid. The quinazolinedione ring is then prepared using the chemistry described earlier to give a precursor B to the invention compound.

B

In a similar series of reactions depicted in Scheme 17, the ortho-fluoro nitro compound is reacted with an α-nucleophile substituted ketone, and the resulting product is likewise reduced. In this sequence, the resulting aniline forms a cyclic imine, which is further reduced with H2 over Pd/C or by chemical hydride reducing agents such as sodium borohydride or sodium cyanoborohydride to give the dihydroquinoline. Such reductive aminations are well-known in the art and are typically performed in THF, alcohol, water alcohol mixtures, or in water DMF mixtures. The remaining steps to produce C follow those of Scheme 16. When the R₅ substituent is a leaving group (e.g., R5 = halo), compounds B and C may be further reacted with nucleophiles (such as pyrrolidine or piperidine) to give compounds of Formula I as in the previous schemes. Also, as indicated in Schemes 17-19, Rj,- can have any of the meanings disclosed for R_h.

Scheme 17

In Scheme 18, an R₃ amino group is attached to the tricyclic compound via nitration and reduction. Scheme 18

R₃= H

As depicted in Scheme 19, target tricylic compounds such as C are prepared in a slightly different manner. In this variant approach, XH (wherein X is O, S, or NH, for example) is attached to the phenyl ring of the starting aniline, and a leaving group L (such as halo) is attached alpha to the ketone reactant. The nucleophile may be activated with bases such as sodium hydride or potassium hydride, triethylamine or l,8-diazabicyclo[5.4.0]undec-7-ene (DBU), or sodium, potassium, or cesium carbonate to displace the leaving group L. In this sequence, the resulting aniline forms a cyclic imine, which is further reduced with H2 on

Pd/C or by chemical hydride reducing agents such as sodium borohydride or sodium cyanoborohydride to give a dihydroquinoline. Such reductive aminations are well-known in the art and are typically performed in THF, alcohol, water alcohol mixtures, or in water DMF mixtures. The dihydroquinoline intermediate is reacted with chloral hydrate, and then an acid to form the dione ring. The dione ring is subsequently opened by reaction with a base, for example sodium hydroxide and hydrogen peroxide, to give the benzoic acid.

The quinazolinedione ring is then prepared by first forming an ester on the benzoic acid as provided earlier, followed by reaction of the benzoic acid ester with chlorosulfonylisocyanate or the like at temperatures of 0°C and below, followed by treatment with a base such as triethylamine or diisopropylethylamine to provide compounds of structure C. When R5 is a leaving group such as CI or F, the invention compound precursor B (in Scheme 16) and the invention compound D (in Scheme 19) can be prepared by coupling to the R5 a side chain, e.g., various

heterocyclic amines _N * ^t0 produce the desired derivatives. Alternatively, carbocycles and aryls may also be introduced as R5 side chains using palladium catalyzed couplings with tin or bornate carbocycles and aryls, for example when R5 is a Br, I, or triflate.

It should be noted from Schemes 16-19 that R^ and R_n> will form chiral centers, giving R and S enantiomers and diastereomers. Such enantiomers or diastereomers may be separated, if desired, by chiral HPLC at any stage. Resolution of any of the intermediates may be performed with techniques of fractional crystallization using mandelic acid, tartaric acid, or other chiral, optically pure acid resolving agents. Chiral benzylic amines (such as α- methylbenzyl amine) can be used in the preparation of starting materials for the above schemes, and chiral amides may also be prepared using chiral acids, such as mandelic acid and the like. The isomers can then be separated and the chiral amine can be hydrogenated, or the chiral amide can be hydrolyzed.

Scheme 20 illustrates synthesis of compounds of Formula I wherein one or both of R4 and R6 are halo via halogenation. The halogenation is carried out on a

2-aminobenzoic acid where one or both of R4 and Rg is hydrogen. If both R4 and

Rg in the benzoic acid are H, then halogenation can be accomplished at both positions selectively or simultaneously. Thus, for example, chlorination at R4 or

Rg is achieved by reaction of the benzoic acid with N-chlorosuccinimide, t-butylhypochlorite, chlorine gas, and the like. Similarly, bromination at R4 and

Rg can also be accomplished by reaction of the benzoic acid with Br2,

N-bromosuccinimide, and the like. Such halogenations are well-known in the art. Halogenation thus provides the respective mono- or dihalo-compound. The halogenated benzoic acid then can be further reacted as shown in earlier schemes to provide the quinazolinediones of Formula I.

Scheme 20

T, Y = CI, Br, F, H

Formula I

In Scheme 21, compounds where Rg is H are halogenated as described above to provide the corresponding 3-halo-2-aminobenzoic acid (Y = halo). This intermediate can then be diazotized by reaction of the 2-amino group with sodium nitrite or t-butyl nitrite, which is then converted to a 2-halobenzoic acid in the presence of an appropriate sodium, potassium, or copper salt such as sodium iodide, potassium chloride, or the like. The resulting 2,3-dihalobenzoic acid (where X and Y both are halo) is then converted to the 3-halo-2-aminobenzoic acid by reaction with an amine R] NH2 in the presence of a copper catalyst. The

3-halo-2-aminobenzoic acid is converted to an amide and cyclized to the corresponding 8-halo-quinazolindione.

Scheme 21

Compounds of Formula I wherein R4 and/or Rg is halo such as chloro or bromo are readily dehalogenated by reaction with metal catalysts under hydrogen pressure (Scheme 22). Suitable catalysts include the many variations of Pd on carbon, Raney nickel, or other reagents that are well-known to effect such dehalogenation.

Scheme 22

R₄ and/or R₆ = CI, Br

Compounds of Formula I wherein R4 and/or Rg are hydrogen can be halogenated to give the mono- or dihalo compound (e.g., R4 or Rg = CI or Br). The invention compounds are preferably prepared by first halogenating a benzoic acid derivative, and then cyclizing the halogenated benzoate (Scheme 23). If both R4 and Rg are H, then halogenation can be accomplished at both positions selectively or simultaneously. Halogenations can be carried out as described above for Scheme 20. The resulting compound is then converted to the 2-substituted-aminobenzoic acid as depicted in Scheme 11 , which is subsequently cyclized.

Invention compounds of Formula I can also be prepared as shown in

Scheme 24. Substituted benzoic acids can be converted into esters (where Z is an ester forming group such as alkyl or benzyl) by a number of methods known by those skilled in the art. The ester is reacted with an isocyanate such as trimethylsilylisocyanate, chlorosulfanyl isocyanate, and chlorocarbonyl isocyanate, followed by treatment with a base such as triethylamine, sodium t-butoxide or the like, to provide a quinazolinedione. This compound may be further reacted, when R5 is a leaving group such as fluoro, with various heterocyclic amines. Again, carbocycles and aryls may also be introduced at R5 if

R5 is a Br, I, or triflate, using palladium catalyzed couplings of tin or boronate carbocycles and aryls. Removal of any protecting groups (Pro) by normal means provides invention compounds such as A.

Scheme 24

Invention compounds of Formula I having a cyano substituent can be prepared as shown in Scheme 25. For example, a benzoic acid wherein Rg is hydrogen can be metallated with a strong base such as lithium hexamethyldisilazide or lithium diisopropylamine. The resulting metallated intermediate can then be quenched with dimethylformamide or an equivalent to provide an aldehyde. The aldehyde can be converted to an oxime by reaction with an alkoxy amine. Other electrophiles such as alkyl halides, activated amides, esters and halide sources such as 1 ,2-dichloro-tetrafluoroethane may also be employed to provide other R₆-substituted benzoic acid derivatives that can be used to make the invention compounds. The oxime is then converted into a cyano group under the cyclization conditions required to form the quinazolinedione ring system (e.g., reaction with phosgene or triphosgene or the like). Deprotection provides invention compounds where Rg is -CN.

Another alternative for preparing invention compounds is illustrated in Scheme 26. Appropriately substituted benzoic acids can be converted into benzamides by any number of methods as described above. A benzamide can then be treated with oxalyl chloride in a chlorinated solvent such as dichloroethane or an equivalent to provide an isocyanate. The isocyanate is reacted with a substituted primary amine to give a benzoyl -substituted urea. This intermediate can be cyclized to form a quinazolinedione ring system by reaction with sodium hydride, potassium hexamethyldisilazane or other non-nucleophilic bases, generally in a solvent such as tetrahydrofuran (THF)/dimethylformamide, THF with 18-crown-6, THF/dioxane, THF/glyme, THF/diglyme, dimethoxyethane/ toluene or an equivalent. The resulting quinazolinedione ring system can then be readily coupled with an appropriately substituted heterocyclic amine (such as those noted above in Table 1 ) by reaction in the presence of a base such as triethyl amine, diisopropylethyl amine, tetramethyl guanidine, and the like in solvents such as dimethyl sulfoxide, dimethylformamide, dimethylacetamide, sulfolane or the equivalent. Any protecting group associated with the heterocyclic amine side chain is then removed by methods known to those skilled in the art to provide invention compounds having Structure A.

Scheme 26

Tricyclic compounds (i.e., where R] and Rg, together with the atoms to which they are attached, form a carbocyclic ring in invention compounds of Formula I) can be prepared according to Scheme 27 where a palladium mediated carbon monoxide insertion on a quinoline (X = Br, I, or triflate) under well- precedented conditions gives rise to an ester. The quinoline ring can then be hydrogenated to provide a tetrahydroquinoline by standard hydrogenation conditions. The remainder of Scheme 27 follows the approach of earlier schemes to provide invention compounds such as G, substituted with a displaceable substituent at R5 (e.g., halo). These compounds may be further reacted with nucleophiles such as amines from Table 1 to give compounds of Formula I. Scheme 27

Compounds of Formula I where K is N may be prepared by the routes shown as illustrated earlier or as indicated in Scheme 28, which follows closely the chemistry shown in Schemes 3 and 24. The leaving groups (e.g. halo) ortho and para to the carboxyl group of the pyridyl starting material are highly activated. The two leaving groups ortho to the pyridine nitrogen are generally chlorine, but fluorine, alkylthiol, and sulfoxides such as methylsulfoxide are also good leaving groups for such compounds. The urea intermediate readily cyclizes to the bicyclic system. The R₅ halo leaving group is readily displaced by reaction with an amine QNH.

Scheme 28

R₅= F, CI, Br, 1

Scheme 29 illustrates the synthesis of benzoic acid starting materials wherein R5 is bromo. The carboxylic acid moiety of the difluoro substituted benzoic acid first is converted to an ester moiety, by conversion to an acid halide or mixed anhydride using an acid anhydride, mixed anhydride, or acid halide such as oxalyl chloride or the like, followed by treatment with an alkanol. The resulting ester is then reacted with 4-methoxybenzylamine or an equivalent to produce the desired 4-substituted benzoic acid derivative. This intermediate is reacted with triethylsilane and trifluoroacetic acid in a chlorinated solvent such as dichloromethane or an equivalent to provide an aniline derivative. Alternatively, one skilled in the art might also employ transition metal catalysis. The resulting aniline is then subjected to diazotization and converted to a bromide by treatment with cuprous bromide. The ester is then hydrolyzed by well-known methods to the desired benzoic acid, which can be used as a starting material to make compounds of the invention.

Scheme 29

In Scheme 30, 4-bromo-2-fluorobenzoic acid derivatives can be selectively chlorinated by treatment with chlorine gas in chlorosulfonic acid at a temperature of 40°C- 100°C. Scheme 30

R₆ = H

Scheme 31 illustrates the use of 4-bromobenzoic acids, in particular, as starting materials to make invention compounds wherein R5 is aryl. The 4-bromobenzoic acids are converted into benzamides by any number of methods known in the art. A benzamide is reacted with oxalyl chloride in a chlorinated solvent such as dichloroethane or an equivalent to provide an isocyanate. The isocyanate is reacted with a substituted primary amine to give a benzoyl substituted urea. This intermediate can be cyclized to form a quinazolinedione ring system by reaction with sodium hydride, potassium hexamethyldisilazide or other non-nucleophilic bases in tetrahydrofuran/dimethylformamide, tetrahydrofuran with 18-crown-6, toluene/dioxane, tetrahydrofuran/glyme, tetrahydrofuran/diglyme, glyme/toluene or an equivalent. The resulting 3-aminoquinazolinedione ring system can then be readily coupled with a stannane or boronic acid derivative of a substituted aryl such as phenyl or substituted aromatic heterocycle (Ar).

Alternatively, the 3-position can be protected with a protecting group such as a tert-butyl carbamate, trifluoroacetamide, or 2,5-dimethoxybenzyl group. Protecting groups of these types are well known in the art. The 3-protected quinazolinedione ring system can then be coupled via palladium catalysis with an aromatic (Ar) stannane or boronic acid.

Each of the outlined routes, upon deprotection by standard procedures, provides invention compounds of Formula I where R5 is aryl such as phenyl or substituted phenyl, or heteroaryl such as pyridyl or substituted pyridyl. Scheme 31

R^Ha

Compounds of Formula I wherein R5 is a heteroaryl group are alternatively prepared as illustrated in Scheme 32, where R5 is a substituted thiazole. A 3-protected 7-bromoquinazolinedione is reacted with 1-tributyl- ethoxyvinyltin in the presence of a palladium catalyst. The resulting R₅-substituted adduct is reacted with a brominating reagent such as n- bromosuccinimide and the like in tetrahydrofuran/H2θ to provide an α-bromoketone moety as R₅. Reaction of this intermediate with a thioamide (or thiourea) in a polar solvent such as dimethyl formamide, dimethylacetamide, or ethanol, and at an elevated temperature of about 80°C to 120°C, effects cyclization to form a thiazolyl group. Deprotection by known methods can then be applied to provide invention compounds of Formula I wherein R5 is the heteroaryl, optionally substituted with T, which is H, alkyl, substituted alkyl, NH₂, NH-alkyl and N-dialkyl. Scheme 32

I

T= H, alkyl, substituted alkyl, NH2, NH-alkyl and N?dialkyl.

Alternatively, R₅-aromatic or heterocyclic aromatic compounds of Formula I are prepared as shown in Scheme 33. A 4-bromo-2-fluorobenzoic acid first undergoes esterification (Z is alkyl or benzyl), and then the ester is reacted with a substituted primary amine (R1NH2) in dimethylsulfoxide (DMSO) at elevated temperature of about 100°C to provide an anthranilic ester. The amine moiety of the antranilic ester is then reacted with an appropriately protected source of NH to provide the corresponding amide. The resulting amido aniline is then cyclized by reaction with phosgene, CDI, or the like, to generate the quinazolinedione. The cyclization typically is carried out in a solvent, such as ethereal solvents, chlorinated hydrocarbons such as chloroform, or aromatic hydrocarbons such as toluene, and in the presence of a base such as triethylamine or NaHCO3. The quinazolinedione ring system is then further modified as described in earlier schemes to provide the desired R₅-aryl (Ar) compound of Formula I.

As noted above, R5 in Formula I is referred to as the "side chain" of the quinazolinedione nucleus. The R5 side chains are any of those typically found on the quinolone antibiotics. Most of the R5 side chain reactants required to make the Formula I compounds are readily available from commercial sources. Typical R5 side chains are shown in Table 1 above.

The synthesis of the R5 side chains can be accomplished by standard synthetic methods, for example as shown in the following schemes or as found in the literature. Those of ordinary skill in the art will be able to make any of the starting materials required to prepare the invention compounds, although most are available from commercial sources. Some of the sidechains were prepared as disclosed in WO 01/53273 or as otherwise provided in the following schemes.

Scheme Al generally illustrates the synthesis of typical pyrrolidines, which are preferred side chains (R5) for invention compounds of Formula I. In

Scheme Al, appropriately activated enones can undergo [3+2]cycloadditions under the conditions described by Tsuge et al. (Recent advances in azomethine ylid chemistry. In: Advances in Heterocyclic Chemistry [Katritsky A., ed.] San Diego: Academic Press, 231 -349). These reactions are carried out in a chlorinated hydrocarbon solvent such as dichloromethane, chloroform, or dichloroethane and the like, and in the presence of a catalytic acid such as trifluoacetic acid, to provide substituted pyrrolidines (wherein Sj, S2, S3, and S4 independently are alkyl, substituted alkyl, aryl, amino, alkyl and dialkylamino). These intermediates can then be treated with hydroxylamine or any O-alkylated or arylated hydroxylamine under a variety of conditions known to those skilled in the art to provide oximated substituted pyrrolidines. The oximes are reduced to amines with lithium aluminum hydride, diisobutylaluminum hydride, borane, or by selective catalytic hydrogenation. The resulting primary amines can then be protected using a number of methods as described in "Protecting Groups in Organic Synthesis" by Theodora Green (supra). The benzylic pyrrolidine can then be deprotected by hydrogenation, and the resulting pyrrolidine used in the preparation of 7-cyclic amino substituted 3-aminoquinazolinediones of Formula I as shown in the schemes above.

hydroxylamine

In Scheme A2, enoates (or vinylogous nitriles) may also be used in [3+2]cycloadditions to provide 3- and 4-substituted pyrrolidines. The ester (or nitrile) functionality can then be treated directly with alkyl lithium, -aluminum, or reagents at low temperature (0°C) to provide S \ substituted carbonyl groups, or the ester (Z is alkyl or benzyl) can be hydrolyzed under conditions usually employed by those skilled in the art to provide carboxylic acids. This intermediate can then be transformed into an acid chloride with oxalyl chloride and catalytic dimethylformamide in solvents such as dichloromethane or chloroform or into an activated amide (Singh J., Satyamurthi N., Aidhen I., Singh J., Prakt. Chem. [Weinheim, Ger.], 2000;342(4):340-347). An acid chloride can be converted into a ketone using organocopper reagents (Lipshutz B.H., Sengupta S., Org. React. [N.Y.], 1992;41 : 135-631), and Weinreb amides can be converted into ketones according to the methods described by Weinreb (Tetrahedron Lett., 1981 ;22(39):3815-3818). The resulting ketones can then be converted into pyrrolidines (optionally substituted with S2, S3, and S4) as described in

Scheme Al. As noted above, pyrrolidines and substituted pyrrolidines are preferred R5 groups in Formula I.

Scheme A2

In Scheme A3, 3-carboxylic acid N-benzyl substituted pyrrolidines (Scheme A2) can be converted into amides by a number of methods well-known to those who practice the art of organic synthesis. The amides can then be treated with lithium aluminum hydride in an ethereal solvent such as diethyl ether or tetrahydrofuran or the like to provide amines that can be protected as described in Scheme Al . Hydrogenation with palladium catalysis provides an appropriately substituted pyrrolidine (S2, S3, S4 are independently alkyl, lower alkyl, aryl, etc.). Scheme A3

In Scheme A4, a 3-carboxypyrrolidinone [Culbertson T.P., Domagala J.M., Nichols J.B., Priebe S., Skeean R.W., J. Med. Chem., 1987;30( 10): 171 1-1715] can be converted into an acid chloride or Weinreb amide in the same fashion as that defined in Scheme A3. The acid chlorides are reacted with an organocopper reagent or an organo Grignard reagent (for a Weinreb amide) to provide a ketone that can be manipulated as described in Scheme Al to provide an appropriately substituted pyrrolidine with a variety of substitutions at S] (alkyl, lower alkyl, substituted alkyl, aryl). The use of S-methylbenzyl (or

R-methylbenzyl) as a protecting group for the pyrrolidine nitrogen allows for the separation of enantiomers and diastereomers at any step in the reaction sequence.

In a particular variant of this approach as provided in Scheme A4.1, the ketone is formed from the Weinreb amide starting compound. Oxime formation and reduction provides the primary amine, and removal of the protecting group provides the target compound

Scheme A14.1

In Scheme A5, the protected dihydropyrrole undergoes [3+2] cycloaddition with the imine oxide generated in situ from hydroxylbenzyl amine to provide the bicyclic intermediate. Removal of the benzyloxycarbonyl group and cleavage of the N-O bond can be effected under hydrogenation conditions to provide the target sidechain.

Scheme A5

A [3+2] cycloaddition approach is employed as the first step in an approach to a [3.3.0] heterocyclic sidechain as depicted in Scheme A6 starting from the N-benzyl protected dihydropyrrole. Cleavage of the N-O bond of the cycloaddition product using lithium aluminum hydride gives the shown pyrrolidinol derivative. Boc protection of the primary amine, followed by removal of the THP protecting group, gives the shown pyrrolidinyl diol. Conversion of the primary alcohol to a leaving group using DAST and intermolecular cyclization gives the fused bicyclic compound. The benzyl protecting group is then removed.

Scheme A7 provides an approach to the synthesis of a sidechain incorporating a thiophene core. Treatment of the thiophene starting compound with bromine in the presence of sodium acetate provides the bromide. The keto moiety is then converted to the benzyl oxime, which is reduced to the primary amine using borane. A chloromethyl group is then attached to the 2-positi^'on using HCI in the presence of formaldehyde. Protection of the primary amine, with concomittant cyclization via displacement of the chloride provides the bicyclic compound. Stannylation using butyl lithium, followed by quenching with tri-n- butyltin chloride provides the target compound, ready for coupling to the quinazolinedione core.

In Scheme A8, 2-thiophenacetonitrile is treated with 1,2 dibromoethane in the presence of base to provide the cyclopropanecarbonitrile.

In Scheme All, the carboxylic acid moiety of the pyrrolidinyl starting compound is converted to a Weinreb amide, which undergoes reaction with cyclopropyl lithium to provide the corresponding ketone. The ketone is converted to a primary amino group via formation of the oxime, and then hydrogenation in the presence of Raney Nickel to provide the target compound.

In Scheme A12, the starting compound undergoes reaction with N,N dibenzylacrylamide to provide the shown pyrrolidinyl ketone. Cyclopropanation of the ketone moiety provides the target compound after removal of the protecting groups (Angew. Chemie Int. Ed. Eng. 1996, 35, 413).

Scheme A12, provides a synthesis for an additional pyrrolidinyl sidechain using techniques known to those skilled in the art. In one approach, the acid moiety in the starting compound is treated with isobutyl chloroformate in the presence of base to form the mixed anhydride. Conversion of the mixed anhydride to the diazomethyl compound using l-methyl-3-nitro-l- nitrosoguanidine and KOH, followed by treatment with HBr HOAc, gives rise to α-bromomethyl ketone. The alpha-bromomethyl ketone is readily converted to the fluoromethyl ketone using a fluorine source such as KF. Reductive amination of using benzylamine and a reducing agent such as sodium triacetoxyborohydride provides the fluoroethylaminopyrrolidinone derivative. Reduction of the amide moiety in the pyrrol idinone, followed by hydrogenolysis to remove the benzyl moieties provided the target compound.

In Scheme A13, the Weinreb amide is prepared from the corresponding carboxylic acid starting compound as provided earlier. Formation of the phenyl ketone from the Weinreb amide is effected via addition of fluorophenyl lithium. Oxime formation, followed by reduction, provides the primary amine. Lithium aluminum hydride reduction of the amide moiety is followed by protection of the primary amine. The pyrrolidinyl nitrogen is then deprotected as provided in Scheme A4 and then is reprotected. A series of purifications and deprotection procedures provides the target compound.

The diastereomers are separated, and the benzylether protecting group is selectively removed to afford the primary alcohol. The lactone is then reduced with LAH.

It should be recognized from all of the above schemes that substitutions on ring systems such as a pyrrolidine, piperazine, or piperidine ring will form chiral centers giving R and S enantiomers and diastereomers. Such enantiomers or diastereomers may be separated, if desired, by chiral HPLC at any stage. Resolution of any of the intermediates may be performed with techniques of fractional crystallization using mandelic acid, tartaric acid, or other chiral, optically pure acid resolving agents. Chiral benzylic amines can be used in the preparation of starting materials for the above schemes, and chiral amides may also be prepared using chiral acids, such as mandelic acid and the like. The isomers can then be separated and the chiral amine can be hydrogenated, or the chiral amide can be hydrolyzed. Some of the compounds of Formula I are capable of further forming pharmaceutically acceptable acid-addition and/or base salts. All of these forms are within the scope of the present invention.

Pharmaceutically acceptable acid addition salts of the compounds of Formula I include salts derived from nontoxic inorganic acids such as hydrochloric, nitric, phosphoric, sulfuric, hydrobromic, hydroiodic, hydrofluoric, phosphorous, and the like, as well as the salts derived from nontoxic organic acids, such as aliphatic mono- and dicarboxylic acids, phenyl-substituted alkanoic acids, hydroxy alkanoic acids, alkanedioic acids, aromatic acids, aliphatic and aromatic sulfonic acids, etc. Such salts thus include sulfate, pyrosulfate, bisulfate, sulfite, bisulfite, nitrate, phosphate, monohydrogenphosphate, dihydrogenphosphate, metaphosphate, pyrophosphate, acetate, trifluoroacetate, propionate, caprylate, isobutyrate, oxalate, malonate, succinate suberate, sebacate, fumarate, maleate, mandelate, benzoate, chlorobenzoate, methylbenzoate, dinitrobenzoate, phthalate, benzensoulfonate, toluenesulfoπate, phenylacetate, citrate, lactate, maleate, tartrate, methanesulfonate, and the like. Also contemplated are salts of amino acids such as arginate and the like and gluconate, galacturonate (see, for example, Berge S.M. et al., "Pharmaceutical Salts," Journal of Pharmaceutical Science, 1977;66:1-19). The acid addition salt of said basic compounds are prepared by contacting the free base form with a sufficient amount of the desired acid to produce the salt in the conventional manner.

Pharmaceutically acceptable base addition salts are formed with metals or amines, such as alkali and alkaline earth metals or organic amines. Examples of metals used as cations are sodium, potassium, magnesium, calcium, and the like. Examples of suitable amines are N,N'-dibenzylethylenediamine, chloroprocaine, choline, diethanolamine, dicyclohexylamine, ethylenediamine, N-methylglucamine, and procaine (see, for example, Berge S.M., supra., 1977). The base addition salts of said acidic compounds are prepared by contacting the free acid form with a sufficient amount of the desired base to produce the salt in the conventional manner. Certain of the compounds of the present invention can exist in unsolvated forms as well as solvated forms, including hydrated forms. In general, the solvated forms, including hydrated forms, are equivalent to unsolvated forms and are intended to be encompassed within the scope of the present invention. Certain of the compounds of the present invention possess one or more chiral centers and each center may exist in the R(D) or 5(L) configuration. The present invention includes all enantiomeric and epimeric forms, as well as the appropriate mixtures thereof.

The compounds of the present invention can be prepared and administered in a wide variety of oral and parenteral dosage forms. Thus, the compounds of the present invention can be administered by injection, that is, intravenously, intramuscularly, intracutaneously, subcutaneously, intraduodenally, or intraperitoneally. Also, the compounds of the present invention can be administered by inhalation, for example, intranasally. Additionally, the compounds of the present invention can be administered transdermaliy. It will be obvious to those skilled in the art that the following dosage forms may comprise as the active component, either a compound of Formula I or a corresponding pharmaceutically acceptable salt of a compound of Formula I. The formulations typically will comprise from about 1 to about 95 percent by weight of the active invention compound.

For preparing pharmaceutical compositions from the compounds of the present invention, pharmaceutically acceptable carriers can be either solid or liquid. Solid form preparations include powders, tablets, pills, capsules, cachets, suppositories, and dispersible granules. A solid carrier can be one or more substances which may also act as diluents, flavoring agents, binders, preservatives, tablet disintegrating agents, or an encapsulating material.

In powders, the carrier is a finely divided solid which is in a mixture with the finely divided active component.

In tablets, the active component is mixed with the carrier having the necessary binding properties in suitable proportions and compacted in the shape and size desired. The powders and tablets preferably contain from five or ten to about seventy percent of the active compound. Suitable carriers are magnesium carbonate, magnesium stearate, talc, sugar, lactose, pectin, dextrin, starch, gelatin, tragacanth, methylcellulose, sodium carboxymethylcellulose, a low melting wax, cocoa butter, and the like. The term "preparation" is intended to include the formulation of the active compound with encapsulating material as a carrier providing a capsule in which the active component with or without other carriers, is surrounded by a carrier, which is thus in association with it. Similarly, cachets and lozenges are included. Tablets, powders, capsules, pills, cachets, and lozenges can be used as solid dosage forms suitable for oral administration.

For preparing suppositories, a low melting wax, such as a mixture of fatty acid glycerides or cocoa butter, is first melted and the active component is dispersed homogeneously therein, as by stirring. The molten homogenous mixture is then poured into convenient sized molds, allowed to cool, and thereby to solidify.

Liquid form preparations include solutions, suspensions, and emulsions, for example, water or water propylene glycol solutions. For parenteral injection liquid preparations can be formulated in solution in aqueous polyethylene glycol solution. Aqueous solutions suitable for oral use can be prepared by dissolving the active component in water and adding suitable colorants, flavors, stabilizing and thickening agents as desired.

Aqueous suspensions suitable for oral use can be made by dispersing the finely divided active component in water with viscous material, such as natural or, synthetic gums, resins, methylcellulose, sodium carboxymethylcellulose, and other well-known suspending agents.

Also included are solid form preparations which are intended to be converted, shortly before use, to liquid form preparations for oral administration. Such liquid forms include solutions, suspensions, and emulsions. These preparations may contain, in addition to the active component, colorants, flavors, stabilizers, buffers, artificial and natural sweeteners, dispersants, thickeners, solubilizing agents, and the like. The pharmaceutical preparation is preferably in unit dosage form. In such form the preparation is divided into unit doses containing appropriate quantities of the active component. The unit dosage form can be a packaged preparation, the package containing discrete quantities of preparation, such as packeted tablets, capsules, and powders in vials or ampoules. Also, the unit dosage form can be a capsule, tablet, cachet, or lozenge itself, or it can be the appropriate number of any of these in packaged form.

The quantity of active component in a unit dose preparation may be varied or adjusted from 0.1 mg to 100 mg preferably 0.5 mg to 100 mg according to the particular application and the potency of the active component as determined by a skilled physician. The composition can, if desired, also contain other compatible therapeutic agents.

In therapeutic use as agents for the treatment of infections caused by a bacteria, the compounds utilized in the pharmaceutical method of this invention are administered at the initial dosage of about 0.01 mg to about 500 mg/kg daily. A daily dose range of about 0.01 mg to about 100 mg/kg is preferred. The dosages, however, may be varied depending upon the requirements of the patient, the severity of the condition being treated, the compound being employed. Determination of the proper dosage for a particular situation is within the skill of the art. Generally, treatment is initiated with smaller dosages which are less than the optimum dose of the compound. Thereafter, the dosage is increased by small increments until the optimum effect under the circumstances is reached. For convenience, the total daily dosage may be divided and administered in portions during the day, if desired. Certain of the compounds of the present invention possess one or more chiral centers and each center may exist in the R or S configuration. The present invention includes all diastereomeric, enantiomeric, and epimeric forms as well as the appropriate mixtures thereof. Additionally, the compounds of the present invention may exist as geometric isomers. The present invention includes all cis, trans, syn, anti, entgegen (E), and zusammen (Z) isomers as well as the appropriate mixtures thereof. The ability of a compound of the invention to inhibit bacterial growth, demonstrate in vivo activity, and enhanced pharmacokinetics are demonstrated using pharmacological models that are well known to the art, for example, using models such as the tests described below.

The effects of test agents on the activity of DNA gyrase was determined by the supercoiling inhibition assay, following reaction conditions recommended by the enzyme supplier (Lucent, Ltd., Leicester, UK), as follows: Reactions are performed in buffer G (35 mM Tris-HCl (pH 7.5), 24 mM KCl, 4 mM MgCl₂,

2 mM DTT, 1.8 mM spermidine, 1 mM ATP, 0.1 mg/mL bovine serum albumin). Relaxed plasmid pBR322 (0.25 μg, Lucent, Ltd., Leicester, UK) is reacted with 1 U E. coli gyrase (Lucent, Ltd., Leicester, UK), in the absence or presence of drugs, for 30 minutes at 37°C. Reactions were stopped by the addition of SDS and proteinase K to respective final concentrations of 1 % and 0.5 mg/mL. After an additional 30 minutes at 37°C, one-tenth volume of 10X loading buffer (0.3% bromophenol blue, 16% Ficoll, 10 mM Na2HPO4) was added, and reactions were loaded onto agarose gels and electrophoresed as described for intercalation assays (Y. Pommier et al. Nucleic Acids Research 1987, 75, 6713-6731.). The concentration of drug inhibiting 50% of the supercoiling activity of DNA gyrase was measured and is given as an IC50 in Table 3.
