Abstract

A new class of diketo acids constructed on pyridinone scaffolds, designed as inhibitors of HTV replication through inhibition of HIV integrase, is described. These compounds are useful in the prevention or treatment of infection by HIV and in the treatment of AIDS and ARC, either as the compounds, or as pharmaceutically acceptable salts, with pharmaceutically acceptable carriers, used alone or in combination with antivirals, immunomodulators, antibiotics, vaccines, and other therapeutic agents, especially other anti-HIV compounds (including other anti-HIV integrase agents), which can be used to create combination anti-HIV cocktails. Methods of treating AIDS and ARC and methods of treating or preventing infection by HIV are also described. Compounds of the present application include those of formula I and include tautomers, regioisomers, geometric isomers, and pharmaceutically acceptable salts thereof, wherein the pyridinone scaffold and R groups are as otherwise defined in the specification. These are combined, with any number of typical other anti-HIV agents (including other integrase-based anti-HIV agents) and other combination therapeutic agents described herein, to provide an effective treatment modality for HIV infections, including AIDS and ARC.

    RELATED APPLICATIONS AND GRANT SUPPORT
  • This application claims the benefit of priority of provisional application number US60/831,990, filed Jul. 19, 2006, provisional application number US60/920,196, filed Mar. 27, 2007, both entitled, “Pyridinone Diketo Acids: Inhibitors of HIV Replication”, and provisional application No. 60/920,197, filed Mar. 27, 2007, entitled, “Pyrinone Diketo Acids: Inhibitors of HIV Replication in Combination Therapy”, each of which applications is incorporated by reference in its entirety herein.
  • The work leading to the instant patent application was supported in part by a grant from the National Institutes of Health, award number A143181. Consequently, the United States government retains certain rights in the invention.
  • FIELD OF THE INVENTION
  • The present invention relates to the field of antiviral therapy, in particular the treatment of HIV infections in humans, preferably in combination therapy.
  • BACKGROUND OF THE INVENTION
  • The human immunodeficiency virus, HIV, encodes three key viral enzymes through its pol gene and these enzymes are critical for the replication of this virus [Fauci, Science, 239, 617-622 (1988); Katz & Skalka, Annu. Rev. Biochem., 63, 133-173 (1994); Frankel, Annu. Rev. Biochem., 67, 1-25 (1998)]. For this reason, these enzymes of the pol gene have been targeted as potential sites of attack in the development of HIV antiviral chemotherapeutic agents [De Clercq, J. Med. Chem. 38, 2491-2517.(1995); Clin. Microbiol. Rev., 10, 674-693 (1997); De Clercq, Nature Reviews: Drug Discovery, 11, 13-25 (2002); De Clercq, J. Med. Chem. 48, 1297-1313 (2005)]. Drug discovery involving two of these enzymes, HIV reverse transcriptase (RT) and HIV protease (PR), and subsequent clinical applications of some of these therapeutic agents in combination therapy for the treatment of acquired immunodeficiency syndrome (AIDS) and AIDS related complex (ARC) in HAART (highly-active antiretroviral therapy) have suggested that this methodology of targeting key viral enzymes represents a useful approach in antiviral chemotherapy [Johnson & Gerber, in “Advances in Internal Medicine,” vol. 44. Mosby: St. Louis, 1-40 (2000); De Clercq, Nature Reviews: Drug Discovery, 11, 13-25 (2002); Miller & Hazuda, Current Opinion in Microbiology, 4, 535-539 (2001); Asante-Appiah & Skalka, Adv. Virus Res., 52, 351-369 (1999); Nair, in “Recent Advances in Nucleosides: Chemistry and Chemotherapy,” Elsevier Science: Netherlands, 149-166 (2002); DeClercq, Intl. J. Biochem. Cell Biol. 36, 1800-1822 (2004)]. While HIV RT and HIV PR have been extensively studied with respect to therapeutics, the third enzyme of the pol gene, HIV integrase, has received much less consideration [Miller & Hazuda, Current Opinion in Microbiology, 4, 535-539 (2001); Nair, Rev. Med. Virol., 12, 179-193 (2002); Nair, Current Pharmaceutical Design, 9, 2553-2565 (2003); Pommier, et al., Nature Rev. Drug Discovery 4, 236-248 (2005); Nair, Frontiers in Med. Chem. 2, 3-20 (2005)].
  • At present there are no drugs in clinical use for HIV/AIDS where the mechanism of action is inhibition of HIV integrase. HIV-1 integrase is a protein of 32 kDa encoded at the 3′-end of the pol gene [Asante-Appiah & Skalka, Adv. Virus Res., 52, 351-369 (1999); Esposito & Craigie, Adv. Virus Res., 52, 319-333 (1999)]. It is involved in the integration of HIV DNA into the host cell chromosome. Because integrase has no human counterpart and because it plays the significant role of completing the invasion of the human cell cell by HIV, it is an attractive target for the discovery of inhibitors of therapeutic potential.
  • Incorporation of HIV DNA into host chromosomal DNA in the cell nucleus catalyzed by integrase apparently occurs by a specifically defined sequence of 3′-processing or tailoring and strand transfer/integration reactions [Asante-Appiah & Skalka, Adv. Virus. Res., 52, 351-369 (1999); Esposito & Craigie Adv. Virus Res., 52, 319-333 (1999)]. Prior to the initiation of the integration process, there is assembly of viral DNA, previously produced by reverse transcription, on the integrase. HIV integrase recognizes specific sequences in the LTRs of viral DNA. Following assembly of viral DNA on integrase, the processing of viral DNA occurs where there is site specific endonuclease activity and two nucleotides are cleaved off from each 3′-end of the double helical viral DNA to produce the tailored viral DNA recessed by two nucleotides and bearing a terminal CAOH-3′. For this initial 3′-processing step, integrase apparently activates the phosphodiester bond towards cleavage. The recessed viral DNA thus produced is joined in the next step to host cell DNA in the nucleus through a trans-esterification reaction. In this step, integrase positions the 3′-OH end of the viral DNA for nucleophilic attack on the phosphodiester bond in the host DNA. In the subsequent step, there is cleavage of 4-6 by in host DNA and the coupling involves the joining of processed CAOH-3′ viral DNA ends to the 5′-phosphate ends of the host DNA. Finally, there is repair of the resulting gapped intermediate mediated by host cell enzymes, although a role here for the integrase is also possible.
  • A variety of compounds are inhibitors of HIV integrase but some of these compounds are non-specific inhibitors of the enzyme while evidence suggests that others may possess some specificity. The various classes include nucleotides, oligonucleotides, dinucleotides, and miscellaneous small molecules including heterocyclic systems, natural products, diketo acids, sulfones and others [Nair, Rev. Med. Virol., 12 179-193 (2002); Nair, Current Pharmaceutical Design, 9, 2553-2565 (2003); Chi and Nair, Bioorg. Med. Chem. Lett. 14, 4815-4817 (2004); Nair and coworkers, J. Am. Chem. Soc., 122, 5671-5677 (2000)].
  • The class of previously studied compounds that are most directly relevant to this patent are diketo acids with aryl or heteroaryl substitutions. Some of these compounds are inhibitors of HIV integrase, but most commonly of only the strand transfer step. The integrase inhibition data have been reported in several scientific publications [Wai, et al., “4-Aryl-2,4-dioxobutanoic acid inhibitors of HIV-1 integrase and viral replication in cells,” J. Med. Chem. 43, 4923-4926 (2000); Pais, G. C. G., et al., “Structure activity of 3-aryl-1,3-diketo-containing compounds as HIV-1 integrase inhibitors,” J. Med. Chem. 45, 3184-3194 (2002); Marchand, C., et al., “Structural determinants for HIV-1 integrase inhibition by β-diketo acids,” J. Biol. Chem. 277, 12596-12603 (2002); Sethi, M., et al., “Design and synthesis of novel indole beta-diketo acid derivatives as HIV-1 integrase inhibitors,” J. Med. Chem. 47, 5298-5310 (2004); Zhang, et al., “Azido-containing aryl β-keto acid HIV-1 integrase inhibitors,” Bioorg. Med. Chem. Lett. 13, 1215-1219 (2003), Nair, et al., “HIV integrase inhibitors with nucleobase scaffolds: discovery of a highly potent anti-HIV agent,” J. Med. Chem. 49, 445-447 (2006); Nair, et al., “Conceptually novel HIV integrase inhibitors with nucleobase scaffolds: discovery of a highly potent anti-HIV agent,” Antiviral Res. 70, A26 (2006); Sato, et al., “Novel HIV-1 integrase inhibitors derived from quinolone antibiotics,” J. Med. Chem. 49, 1506-1508 (2006); Nair et al., “Beta-diketo acids with purine nucleobase scaffolds: novel selective inhibitors of the strand transfer step of HIV integrase,” Bioorg. Med. Chem. Lett. 16, 1920-1923 (2006), Chi et al., “A novel diketo phosphonic acid that exhibits specific, strand-transfer inhibition of HIV integrase and anti-HIV activity,” Bioorg. Med. Chem. Lett. 17, 1266-1269 (2007)]. Other publications in the area are of peripheral relationship to this patent application.
  • The mechanism of inhibition of HIV integrase by diketo acids may be the result of interaction of the functional groups on these compounds with metal ions in the active site of integrase, resulting in a functional sequestration of these critical metal cofactors [Grobler, J. A., et al., Proc. Natl. Acad. Sci. USA. 99, 6661-6666 (2002)].

  • When the variables involving R1, R2, R3, R4 and R5 occur more than once in any formula I, the definition on each occurrence is independent of its definition at every other occurrence. Regioisomeric pyridinones, in addition to those structurally identified, are also part of this invention. Combinations of pyridinones and variables are permissible only if, in context, such combinations result in stable compounds.
  • The compounds of the present invention are useful in the inhibition of HIV integrase, the prevention or treatment of infection by HIV and in the treatment of the disease known as AIDS. Treating AIDS or preventing or treating infection by HIV is defined as including the treatment of a wide range of states of HIV infection: AIDS, ARC and actual or potential exposure to HIV (e.g., through blood transfusion, exchange of body fluids, bites, needle punctures, exposure to infected patient blood during medical or dental procedures, and other means).
  • Other applications are also part of this invention. For example, the compounds of this invention are useful in the preparation and execution of screening assays for antiviral compounds including in the isolation of viral enzyme mutants and in further understanding of the enzyme, HIV integrase.
  • The present invention also provides for the use of a compound of structural formula (I) to make a pharmaceutical composition useful for inhibiting HIV integrase and in the treatment of AIDS or ARC.
  • The compounds of the present invention may be administered in the form of “well-known pharmaceutically acceptable” salts. The latter is intended to include all acceptable salts such as acetate, lactobionate, benzenesulfonate, laurate, benzoate, malate, bicarbonate, maleate, bisulfate, mandelate, bitartrate, mesylate, borate, methylbromide, bromide, methylnitrate, calcium edetate, camsylate, mucate, carbonate, napsylate, chloride, nitrate, clavulanate, N-methylglucamine, citrate, ammonium salt, dihydrochloride, oleate, edetate, oxalate, edisylate, pamoate, estolate, palmitate, esylate, fumarate, phosphate, diphosphate, gluceptate, polygalacturonate, gluconate, salicylate, glutamate, stearate, glycollylarsanilate, sulfate, hexylresorcinate, subacetate, hydrabamine, succinate, hydrobromide, tannate, hydrochloride, tartrate, hydroxynaphthoate, teoclate, iodide, tosylate, isothionate, triethiodide, lactate, panoate, valerate, and others which can be used as a dosage form for modifying the solubility or hydrolysis characteristics or can be used in sustained release or pro-drug formulations. The pharmaceutically acceptable salts of this invention include those with counterions such as sodium, potassium, calcium, lithium, magnesium, zinc, and from bases such as ammonia, ethylenediamine, N-methyl-glutamine, e, lysine, arginine, ornithine, choline, N,N′-dibenzylethylenediamine, chloroprocaine, diethanolamine, procaine, N-benzylphenethylamine, diethylamine, piperazine, tris(hydroxymethyl)aminomethane, and tetramethylammonium hydroxide.
  • Also, in the case of a carboxylic acid (—COOH) or an alcohol group being present, pharmaceutically acceptable esters can be employed, e.g., acetate, maleate, pivaloyloxymethyl and others, more preferably C1-C20 esters and those esters known in the art for improving solubility or hydrolysis characteristics for use as sustained release or pro-drug formulations. Pharmaceutically acceptable esters can also be employed in the case where a phosphonic acid group [PO(OH)2] is present. Diketo phosphonic acids attached to pyridinone scaffolds are also part of this invention.
  • Therapeutically effective amounts of the compounds of the present invention may be administered to patients orally, parenterally, by inhalation spray, or rectally, in dosage unit formulations containing pharmaceutically-acceptable carriers, adjuvants and vehicles including nanoparticle drug delivery approaches.
