Definitions

  • the present invention relates to acylamino-substituted heteroaromatic compounds of the formula I,
  • the compounds of formula I are valuable pharmaceutically active compounds which are useful in the treatment of various disease states including cardiovascular disorders such as atherosclerosis, thrombosis, coronary artery disease, hypertension and cardiac insufficiency. They upregulate the expression of the enzyme endothelial nitric oxide (NO) synthase and can be applied in conditions in which an increased expression of said enzyme or an increased NO level or the normalization of a decreased NO level is desired.
  • the invention furthermore relates to processes for the preparation of compounds of the formula I, their use, in particular as active ingredients in pharmaceuticals, and pharmaceutical preparations comprising them.
  • Endothelial NO synthase belongs to a group of three isoenzymes which produce nitric oxide (NO) by oxidation of arginine. Endothelially released NO is of central importance in a number of key cardiovascular mechanisms. It has a vasodilating effect and inhibits the aggregation of platelets, the adhesion of leukocytes to the endothelium and the proliferation of intimal smooth muscle cells.
  • Endothelial NO synthase is subject to physiological and pathophysiological regulation both at the transcriptional and at the post-transcriptional level.
  • Enzyme already present in the endothelium may undergo calcium-dependent and calcium- independent activation through phosphorylation of specific amino acids, but also by direct interactions with specific proteins.
  • Stimulators of this, usually transient, NO release are, extracellular arginine, 17 ⁇ -estrogen and the mechanical stimulus exerted bn the luminal surface of the endothelium by the blood flow (shear stress). The latter additionally leads to regulation of eNOS at the transcriptional level.
  • Sessa et al. (Circ. Research 74 (1994) 349) were able by means of exercise training and the increase in shear stress associated therewith to obtain a marked increase in eNOS.
  • eNOS promoter single point mutations in the ⁇ '-flanking region of the eNOS gene
  • a consequence of atherogenesis is the formation of plaques on the inside of the blood vessels, which may in turn lead, through a diminution in the shear stress, to a further decrease in endothelial NO release and a further deterioration in the pathology. Since endothelial NO is also a vasodilator, a decrease thereof frequently also leads to hypertension, which may, as an independent risk factor, cause further organ damage.
  • statins which have already been mentioned are, however, the only substances for which it has been possible to date to show such an increase in eNOS in vivo as a side effect. But in view of the known range of side effects of this class of substances it is unclear how far this effect is present in a toxicologically unproblematic dose.
  • WO 02/064146, WO 02/064545, WO 02/064565 and WO 02/064546 disclose acylated, benzo-condensed cycloalkenylamines which upregulate eNOS expression in endothelial cells and are useful pharmaceutically active ingredients for the treatment of various diseases, but there is an ongoing need for further eNOS expression enhancers with a favorable property profile.
  • the present invention satisfies this need by providing compounds of the formula I and methods of using them.
  • Certain acylamino-substituted heteroaromatic compounds of the formula I have already been described. In many cases the known compounds have been prepared in the course of merely chemical investigations or for use as intermediates in the synthesis of other compounds, and no biological activity of them has been described. Compounds of the formula I and structurally similar compounds for which a pharmaceutical activity has already been described include, for example, certain hypotensive 2-acetylaminobenzimidazoles (Bellasio et al., Farmaco, Ed. Sci., 28 (1973) 164) which, however, do not suggest the 2-(hetero)aroylaminobenzimidazoles comprised by the present invention and their biological activity.

Description

Acylamino-substituted heteroaromatic compounds and their use as pharmaceuticals
The present invention relates to acylamino-substituted heteroaromatic compounds of the formula I,
Figure imgf000002_0001
in which R1, R2, R3, R4 and R5 and X have the meanings indicated below. The compounds of formula I are valuable pharmaceutically active compounds which are useful in the treatment of various disease states including cardiovascular disorders such as atherosclerosis, thrombosis, coronary artery disease, hypertension and cardiac insufficiency. They upregulate the expression of the enzyme endothelial nitric oxide (NO) synthase and can be applied in conditions in which an increased expression of said enzyme or an increased NO level or the normalization of a decreased NO level is desired. The invention furthermore relates to processes for the preparation of compounds of the formula I, their use, in particular as active ingredients in pharmaceuticals, and pharmaceutical preparations comprising them.
Endothelial NO synthase (eNOS, NOS-lll) belongs to a group of three isoenzymes which produce nitric oxide (NO) by oxidation of arginine. Endothelially released NO is of central importance in a number of key cardiovascular mechanisms. It has a vasodilating effect and inhibits the aggregation of platelets, the adhesion of leukocytes to the endothelium and the proliferation of intimal smooth muscle cells.
Endothelial NO synthase is subject to physiological and pathophysiological regulation both at the transcriptional and at the post-transcriptional level. Enzyme already present in the endothelium may undergo calcium-dependent and calcium- independent activation through phosphorylation of specific amino acids, but also by direct interactions with specific proteins. Stimulators of this, usually transient, NO release are, extracellular arginine, 17β-estrogen and the mechanical stimulus exerted bn the luminal surface of the endothelium by the blood flow (shear stress). The latter additionally leads to regulation of eNOS at the transcriptional level. Thus, for example, Sessa et al. (Circ. Research 74 (1994) 349) were able by means of exercise training and the increase in shear stress associated therewith to obtain a marked increase in eNOS.
Whether regulation at the post-transcriptional level is relevant in vivo, has not been unambiguously proven. Thus, for example, administration of a high arginine dose is followed by only a transient improvement in the endothelium-dependent vasorelaxation in patients with coronary heart disease.
On the other hand, the significance of the upregulation of the eNOS protein is scientifically accepted. Thus, there are findings which show that the protective properties of the HMG-CoA reductase inhibitor simvastatin can be attributed, besides to the lipid lowering effect, also in part to an increase in eNOS expression in vivo (Endres et al., Proc. Natl. Acad. Sci. USA 95 (1998) 8880). It is additionally known that single point mutations in the δ'-flanking region of the eNOS gene ("eNOS promoter"), and the reduction in the rate of eNOS gene transcription associated therewith, in the Japanese population is associated with an increase in the risk of coronary spasms (Nakayama et al., Circulation 99 (1999) 2864).
The current assumption therefore is that the transcriptional and post-transcriptional mechanisms of eNOS regulation are seriously disturbed in a large number of disorders, especially in cardiovascular disorders. Even in very early stages of a wide variety of cardiovascular disorders it is possible for a dysfunction of this type in the endothelium lining the blood vessels to lead to a deficiency of bioactive NO, which is manifested as the disorder progresses in the form of measurable pathophysiological and morphological changes. Thus, critical steps in early atherogenesis are speeded up by a decrease in endothelial NO release, such as, for example, the oxidation of low density lipoproteins, the recruitment and deposition of monocytes in the intima of vessels, and the proliferation of intimal cells. A consequence of atherogenesis is the formation of plaques on the inside of the blood vessels, which may in turn lead, through a diminution in the shear stress, to a further decrease in endothelial NO release and a further deterioration in the pathology. Since endothelial NO is also a vasodilator, a decrease thereof frequently also leads to hypertension, which may, as an independent risk factor, cause further organ damage.
The aim of a therapeutic approach to the treatment of these disorders must accordingly be to interrupt this chain of events by increasing the endothelial NO expression. Gene transfer experiments which lead in vitro to overexpression of NO synthase in previously damaged vessels are in fact able to counteract the described processes and are thus evidence of the correctness of this approach (Varenne et al., Hum. Gene Ther. 11 (2000) 1329).
Some low molecular weight compounds which, in cell cultures, may lead to a direct effect on eNOS transcription and expression are disclosed in the literature. The statins which have already been mentioned are, however, the only substances for which it has been possible to date to show such an increase in eNOS in vivo as a side effect. But in view of the known range of side effects of this class of substances it is unclear how far this effect is present in a toxicologically unproblematic dose.
Liao et al. claim in WO 99/47153 and WO 00/03746 the use of rhoGTPase inhibitors and agents which influence the organization of the actin cytoskeleton for increasing eNOS in endothelial cells and for the therapy of various disorders such as, for example, stroke or pulmonary hypertension without, however, indicating a specific way of achieving this.
WO 02/064146, WO 02/064545, WO 02/064565 and WO 02/064546 disclose acylated, benzo-condensed cycloalkenylamines which upregulate eNOS expression in endothelial cells and are useful pharmaceutically active ingredients for the treatment of various diseases, but there is an ongoing need for further eNOS expression enhancers with a favorable property profile. The present invention satisfies this need by providing compounds of the formula I and methods of using them.
Certain acylamino-substituted heteroaromatic compounds of the formula I have already been described. In many cases the known compounds have been prepared in the course of merely chemical investigations or for use as intermediates in the synthesis of other compounds, and no biological activity of them has been described. Compounds of the formula I and structurally similar compounds for which a pharmaceutical activity has already been described include, for example, certain hypotensive 2-acetylaminobenzimidazoles (Bellasio et al., Farmaco, Ed. Sci., 28 (1973) 164) which, however, do not suggest the 2-(hetero)aroylaminobenzimidazoles comprised by the present invention and their biological activity. The activating effect on guanylate cyclase of certain N-benzimidazolylcarboxamides and N- benzothiazolylcarboxamides described in WO 00/27394 seems to depend on the presence of a 3-(3-(dimethylamino)propoxy)-1-(phenylmethyl)-1H-pyrazol-5- carboxamide moiety. In WO 01/97786 the adenosine receptor affinity of certain N- benzothiazolylcarboxamides has been disclosed. In WO 01/83427, WO 98/11073 and Pilyugin et al., Bashkirskii Khimicheskii Zhurnal 8 (2001 ) 18, it has been described that similar compounds exhibit a hypoglycemic activity, antiviral activity or antifungal activity, respectively. There are no indications in the prior art that compounds of the formula I would upregulate the expression of endothelial NO synthase, but it is surprising that they exhibit this activity and therefore are valuable pharmaceutically active ingredients which are useful in the treatment of a variety of diseases including cardiovascular diseases such as, for example, atherosclerosis, thrombosis, coronary artery disease, hypertension and cardiac insufficiency.
A subject of the present invention are novel acylamino-substituted heteroaromatic compounds of the formula I,

Preferred compounds of the formula I are those compounds in which one or some or all of the structural moieties and groups contained therein have preferred meanings, more preferred meanings, even more preferred meanings or most preferred meanings defined above, all combinations of such preferred meanings etc. and/or of specific meanings of a group being a subject of the present invention. With respect to all preferred compounds of the formula I the present invention also includes all stereoisomeric forms and mixtures thereof in all ratios, and their pharmaceutically acceptable salts.
A compound of the formula I or a salt thereof can be prepared, for example, by a process which comprises the acylation of a heteroaromatic amine of the formula II with a carboxylic acid of the formula R5-COOH or a derivative thereof, which process also is a subject of the present invention.
Figure imgf000025_0001
II
Suitable derivatives of the carboxylic acids of the formula R5-COOH are, for example, carboxylic acid chlorides, esters including C C -alkyl esters, such as methyl esters or ethyl esters, optionally substituted aryl esters, such as phenyl esters or nitrophenyl esters, or activated esters, or anhydrides or mixed anhydrides. In the compounds of the formula II and the carboxylic acids of the formula R5-COOH and their derivatives the groups X, R1, R2, R3, R4 and R5 have the meanings indicated above with respect to the compounds of the formula I, or else functional groups can be present in protected form or in the form of a precursor. For example, when a compound of the formula I is to be prepared which contains a carboxylic acid group or an amino group, it may be appropriate that in the acylation reaction these groups are present in protected form, for example as an ester such as a tert-butyl ester or benzyl ester instead of the free carboxylic acid group, or as an acylated amino group such as a tert-butoxycarbonylamino group or benzyloxycarbonylamino group instead of the free amino group, and only subsequent to the acylation the desired final groups are liberated by deprotection. Suitable protective group strategies which may be used in the synthesis of the compounds of formula I are known to the person skilled in the art. An example of a precursor group of a functional group is the nitro group which can be converted into an amino group by reduction, for example by catalytic hydrogenation, after the acylation reaction.
The acylation reactions can be carried out under standard conditions known to the person skilled in the art. In many cases the reaction is favorably performed in an inert solvent or diluent, for example a hydrocarbon or a chlorinated hydrocarbon, such as toluene, 1 ,2-dichloroethane or methylene chloride, an ether, such as tetrahydrofuran, dioxane or 1 ,2-dimethoxyethane, an alcohol such as methanol, ethanol or isopropanol, an amide such as N,N-dimethyIformamide or N-methylpyrrolidone, 'acetonitrile, water, or a else a mixture of two or more solvents or diluents. Depending o the individual case, it may be advantageous to perform the reaction in the presence of a base, for example an inorganic base such as sodium hydroxide, sodium carbonate or sodium hydrogencarbonate, or an organic base such as triethylamine, ethyldiisopropylamine, N-ethylmorpholine or pyridine, and/or in the presence of an acylation catalyst such as 4-dimethylaminopyridine.
If a carboxylic acid of the formula R5-COOH is to be used in the acylation of a compound of the formula II, it is often advantageous to activate the acid or a salt thereof with a condensation agent or coupling agent, for example an agent like those commonly used in peptide chemistry for the formation of amide bonds. Examples of suitable coupling agents are carbodiimides such as dicyclohexylcarbodiimide or diisopropylcarbodiimide, TOTU, i.e. 0-((cyano(ethoxycarbonyl)methylene)amino)- N.N.N'.N'-tetramethyluronium tetrafluoroborate, HATU, i. e. 0-(7-azabenzotriazol-1- yl)-1 ,1 ,3,3-tetramethyluronium hexafluorophosphate, chloroformic acid esters like ethyl chloroformate or isobutyl chloroformate, tosyl chloride, propylphosphonic acid anhydride or carbonyldiimidazole. Depending on the individual case, the suitable reaction temperature may lie within a wide range. For example, when employing into the acylation reaction a carboxylic acid in the presence of a coupling agent or a carboxylic acid chloride, the reaction can often be carried out at room temperature.
Subsequent to the acylation reaction, besides the above-mentioned deprotection of protected groups or the conversion of a precursor group into the desired final group, optionally further functionalizations or modifications of the obtained compounds can be carried out and suitable functional groups can, for example, be esterified, amidated, transesterified, hydrolyzed, alkylated, sulfonylated, acylated, reduced, oxidized, converted into a salt, or subjected to other reactions. The starting compounds for the preparation of the compounds of the formula I are commercially available or can be prepared according to or analogously to literature procedures. Ail reactions for the synthesis of the compounds of the formula I are per *se well-known to the skilled person and can be carried out under standard conditions # according to or analogously to procedures described in the literature, for example in Houben-Weyl, Methoden der Organischen Chemie (Methods of Organic Chemistry), Thieme-Verlag, Stuttgart, or Organic Reactions, John Wiley & Sons, New York. As mentioned above, depending on the circumstances of the individual case, in order to avoid side reactions during the synthesis of a compound of the formula I, in any reaction step it can be necessary or advantageous to temporarily block functional groups by introducing protective groups and to deprotect them in a later stage of the synthesis, or introduce functional groups in the form of precursor groups which in a later reaction step are converted into the desired functional groups. Such synthesis strategies and protective groups and precursor groups which are suitable in an individual case are known to the skilled person. If desired, the compounds of the formula I can be purified by customary purification procedures, for example by recrystallization or chromatography.
The compounds of the formula I are useful pharmaceutically active compounds which upregulate the expression of endothelial NO synthase and can be employed as medicaments for the treatment of various diseases. In the context of the present invention, treatment is understood as comprising both therapy, including alleviation and cure, of disease symptoms and prevention or prophylaxis of disease symptoms, such as, for example, the prevention of the appearance of asthmatic disease symptoms or the prevention of myocardial infarction or of myocardial reinfarction in relevant patients. The diseases or disease symptoms can be acute or chronic. Diseases which can be treated with the compounds of the formula I include, for example, cardiovascular diseases like stable and unstable angina pectoris, coronary heart disease, Prinzmetal angina (spasm), acute coronary syndrome, heart failure, myocardial infarction, stroke, thrombosis, peripheral artery occlusive disease

The compounds of the formula I and their pharmaceutically acceptable salts, optionally in combination with other pharmaceutically active compounds, can be administered to animals, preferably to mammals, and in particular to humans, as pharmaceuticals by themselves, in mixtures with one another or in the form of pharmaceutical preparations. Further subjects of the present invention therefore also are the compounds of the formula I and their pharmaceutically acceptable salts for use as pharmaceuticals, their use as transcription stimulating agents or upregulating agents of endothelial NO synthase, for example in conditions in which an increased expression of said enzyme or an increased NO level or the normalization of a decreased NO level in a patient is desired, and in particular their use in the treatment, i. e. the therapy and prevention, of the above-mentioned syndromes, as well as their use for preparing medicaments for these purposes. Furthermore, a subject of the present invention are pharmaceutical preparations (or pharmaceutical compositions) which comprise an effective dose of at least one compound of the formula I and/or a pharmaceutically acceptable salt thereof and a pharmaceutically acceptable carrier, i.e. one or more pharmaceutically acceptable carrier substances or vehicles and/or additives or excipients.

for use as stimulating agent of the expression of endothelial NO synthase, or for use in the treatment of cardiovascular diseases, stable or unstable angina pectoris, coronary heart disease, Prinzmetal angina, acute coronary syndrome, heart failure, ' myocardial infarction, stroke, thrombosis, peripheral artery occlusive disease, endothelial dysfunction, atherosclerosis, restenosis, endothel damage after PTCA, hypertension, essential hypertension, pulmonary hypertension, secondary hypertension, renovascular hypertension, chronic glomerulonephritis, erectile dysfunction, ventricular arrhythmia, diabetes, diabetes complications, nephropathy, retinopathy, angiogenesis, asthma bronchiale, chronic renal failure, cirrhosis of the liver, osteoporosis, restricted memory performance or a restricted ability to learn, or for the lowering of cardiovascular risk of postmenopausal women or of women taking contraceptives, and, provided that their use as pharmaceuticals has not yet been known, their use as pharmaceutical as well as pharmaceutical preparations which comprise an effective dose of at least one compound of the formula I and/or a pharmaceutically acceptable salt thereof and a pharmaceutically acceptable carrier. With respect to compounds of the formula I for use as stimulating agent of the expression of endothelial NO synthase or for use as pharmaceutical or for use in the treatment of the beforementioned diseases all explanations given above with respect to the compounds of the formula l per se likewise apply. Thus, a further subject of the invention also are compounds of the formula I for use as stimulating agent of the expression of endothelial NO synthase or for use as pharmaceutical or for use in the treatment of the beforementioned diseases, in which one or more, including all, of the groups and numbers in the definition of the compounds have preferred meanings, more preferred meanings, even more preferred meanings or most preferred meanings or any specific meaning.
The pharmaceuticals according to the invention can be administered orally, for example in the form of pills, tablets, lacquered tablets, sugar-coated tablets, granules, hard and soft gelatin capsules, aqueous, alcoholic or oily solutions, syrups, emulsions or suspensions, or rectally, for example in the form of suppositories. Administration can also be carried out parenterally, for example subcutaneously, intramuscularly or intravenously, in the form of solutions for injection or infusion. Other suitable administration forms are, for example, percutaneous or topical administration, for example in the form of ointments, tinctures, sprays or transdermal therapeutic systems, or the inhalative administration in the form of nasal sprays or aerosol mixtures, or, for example, microcapsules, implants or rods. The preferred administration form depends, among others, on the disease to be treated and on its severity.
„The amount of a compound of the formula I and/or its pharmaceutically acceptable salts in the pharmaceutical preparations normally ranges from about 0.2 to about 800 mg, preferably from about 0.5 to about 500 mg, in particular from about 1 to about 200 mg, per dose, but depending on the type of the pharmaceutical preparation it may also be higher. The pharmaceutical preparations usually comprise from about 0.5 to about 90 % by weight of the compounds of the formula I and/or their pharmaceutically acceptable salts. The production of the pharmaceutical preparations can be carried out in a manner known per se. To this end, one or more compounds of the formula I and/or their pharmaceutically acceptable salts, together with one or more solid or liquid pharmaceutical carrier substances and/or additives (or auxiliary substances) and, if desired, in combination with other pharmaceutically active compounds having therapeutic or prophylactic action, are brought into a suitable administration form or dosage form which can then be used as a pharmaceutical in human or veterinary medicine.
For the production of pills, tablets, sugar-coated tablets and hard gelatin capsules it is possible to use, for example, lactose, starch, for example maize starch, or starch derivatives, talc, stearic acid or its salts, etc. Soft gelatin capsules and suppositories can comprise, for example, fats, waxes, semisolid and liquid polyols, natural or hardened oils, etc. Suitable carrier substances for the preparation of solutions, for example of solutions for injection, or of emulsions or syrups are, for example, water, physiologically sodium chloride solution, alcohols such as ethanol, glycerol, polyols, sucrose, invert sugar, glucose, mannitol, vegetable oils, etc. It is also possible to lyophilize the compounds of the formula I and their pharmaceutically acceptable salts and to use the resulting lyophilisates, for example, for preparing preparations for injection or infusion. Suitable carriers for microcapsules, implants or rods are, for example, copolymers of glycolic acid and lactic acid. Besides the compound or compounds of the invention and carrier substances, the ^ pharmaceutical preparations can also contain additives such as, for example, fillers, disintegrants, binders, lubricants, wetting agents, stabilizers, emulsifiers, dispersants, preservatives, sweeteners, colorants, flavorings, aromatizers, thickeners, diluents, buffer substances, solvents, solubilizers, agents for achieving a depot effect, salts for altering the osmotic pressure, coating agents or antioxidants.
The dosage of the compound of the formula I to be administered and/or of a pharmaceutically acceptable salt thereof depends on the individual case and is, as is customary, to be adapted to the individual circumstances to achieve an optimum effect. Thus, it depends on the nature and the severity of the disorder to be treated, and also on the sex, age, weight and individual responsiveness of the human or animal to be treated, on the efficacy and duration of action of the compounds used, on whether the use is for the therapy of a acute or chronic disease or prophylactic, or on whether other active compounds are administered in addition to compounds of the formula I. In general, a daily dose of from about 0.01 to about 100 mg/kg, preferably from about 0.1 to about 10 mg/kg, in particular from about 0.3 to about 5 mg/kg (in each case mg per kg of bodyweight) is appropriate for administration to an adult weighing approximately 75 kg in order to obtain the desired results. The daily dose can be administered in a single dose or, in particular when larger amounts are administered, be divided into several, for example two, three or four individual doses. In some cases, depending on the individual response, it may be necessary to deviate upwards or downwards from the given daily dose.
The compounds of the formula I can also be used for other purposes than those indicated in the foregoing. Non-limiting examples include diagnostic purposes, such as the use in the examination of cell or tissue samples, the use as biochemical tools and the use as intermediates for the preparation of further compounds, e.g. pharmaceutically active compounds.

Determination of activation of eNOS transcription Activation of eNOS transcription was determined as described in detail in Li et al., "Activation of protein kinase C alpha and/or epsilon enhances transcription of the human endothelial nitric oxide synthase gene", Mol. Pharmacol. 53 (1998) 630.
Briefly, a 3.5kB long fragment 5' of the starting codon of the eNOS gene was cloned, sequenced and cloned in firefly luciferase expression plasmids to monitor activation of the eNOS promoter by reporter gene activity. A human endothelial cell line stable transfected and expressing this promoter-reporter construct was used for compound testing. Cells were incubated for 18 h with compounds.
All compounds were dissolved in sterile dimethyl sulfoxide (DMSO). A final concentration of 0.5% DMSO in complete medium was allowed. Induction of reporter gene expression in these cells was measured using a standard luciferase assay system (Promega, Cat. No E150) according to the manufacturer's instructions. Luciferase induction in cells incubated with compounds were compared to those incubated with solvent alone. The ratio of both activities (transcription induction ratio, TIR) was plotted as a function of compound concentration. Typically, TIR values started at low concentrations at a ratio of 1 , indicating no compound effect, and extended up to a maximum TIR value TIR(max) which indicates the increase of the eNOS transcription. EC50 values of transcription induction ratios as a function of compound concentration were determined graphically.
The effect of compounds on eNOS-transcription was confirmed in a second assay based on eNOS protein detection. Primary human umbilical vein cord endothelial cells (HUVEC) were isolated and cultivated according to standard procedures. Confluent cells were incubated with compounds for 18 h and the effect on eNOS protein expression determined by a quantitative Western blotting procedure. After compounds incubation, HUVEC were lysed in ice-cold lysis buffer containing 10 mM Tris-HCI, pH 8.0, 1 % SDS and protease inhibitors. The lysate was subjected to a standard denaturating polyacrylamide gel electropheresis and blotted to nitrocellulose membranes. Using a specific primary monoclonal antibody (Transduction Laboratories, UK) and alkaline phosphatase labelled secondary antibody (Jackson Labs), a specific eNOS protein band was visualized and quantified based on a chemifluorescence detection method.
The results obtained with example compounds of the invention are listed in Table 4.

The effect of the compounds of the invention can also be investigated in the following animal models (animal experiments are performed in accordance to the German animal protection law and to the guidelines for the use of experimental animals as given by the Guide for the Care and Use of Laboratory Animals of the US National Institutes of Health).
Animals and Treatment (Experiments A - C)
ApoE and eNOS deficient mice (C57BL/6J background, Jackson Laboratory, Bar Harbor, Me) are used. All animals are 10 to 12 weeks of age and weigh 22 to 28 g. Three days before surgery mice are divided into 4 groups (apoE control, n = 10 to 12; apoE with test compounds, n = 10 to 12; eNOS control, n = 10 to 12; eNOS with test compounds, n = 10 to 12) and receive either a standard rodent chow (containing 4 % fat and 0.001 % cholesterol; in the following designated as placebo group) or a standard rodent chow + test compound (10 or 30 mg/kg/d p.o.).
A. Anti-hypertensive effect in ApoE knockout mice
Blood-pressure is determined in conscious mice using a computerized tail-cuff system (Visitech Systems, Apex, Nc). After treatment of ApoE deficient mice and eNOS deficient mice with the test compounds the blood pressure is compared to the results obtained with a placebo treatment.
B. Inhibition of neointima formation and atherogenesis (femoral artery cuff) After 3 day treatment of ApoE deficient mice with the respective compound, (10 mg/kg/d pressed in chow), animals are anesthetized with an intraperitoneal injection "of pentobarbital (60 mg/kg) followed by an intramuscular injection of xylazin (2 _ mg/kg) and a cuff is placed around the femoral artery as described in Moroi et al.(J. Clin. Invest. 101 (1998) 1225). Briefly, the left femoral artery is dissected. A non- occlusive 2.0 mm polyethylene cuff made of PE-50 tubing (inner diameter 0.56 mm, outer diameter 0.965 mm, Becton Dickinson, Mountain View, Ca) is placed around the artery and tied in place with two 7-0 sutures. The right femoral artery is isolated from the surrounding tissues but a cuff is not placed. Treatment with the respective compound is continued for 14 days after surgery. Then the animals are sacrificed. The aorta are taken for determination of vascular eNOS expressions by quantitative western blotting. Both femoral arteries are harvested, fixed in formalin and embedded in paraffin. 20 cross sections (10 μm) are cut from the cuffed portion of the left femoral artery and from the corresponding segment of the right artery. Sections are subjected to standard hematoxylin and eosin staining. Morphometric analyses are performed using an image analysis computer program (LeicaQWin, Leica Imaging Systems, Cambridge, GB). For each cross section the area of the lumen, the neointima and the media are determined. To this end, the neointima is defined as the area between the lumen and the internal elastic lamina and the media is defined as the area between the internal and the external elastic lamina. The ratio between the area of the neointima and the area of the media is expressed as the neointima/media ratio. The results obtained in the compound group are compared to those obtained in the placebo group.
C. Prevention of atherosclerotic plaque formation in chronic treatment
ApoE deficient mice are treated for 16 weeks with the respective compound pressed in chow and finally sacrificed. Aortas are removed from each mouse, fixed in formalin and embedded in paraffin. Plaque formation is measured via lipid lesions formation in the aortas (from aortic arch to diaphragm) and is analyzed by oil red O staining. For quantifying the effect of the respective compound on vascular eNOS expression the femoral arteries are used in this experiment. The results obtained in the compound group are compared to those obtained in the placebo group.
TJ. Improvement of coronary function in diseased ApoE deficient mice
Old Male wild-type C57BL/6J mice (Charles River Wiga GmbH, Sulzfeld), and apoE deficient mice (C57BL/6J background, Jackson Laboratory, Bar Harbor, Me) 6 month of age and weighing 28 to 36 g are used in the experiments. Mice are divided into 3 groups (C57BL/6, n = 8; apoE control, n = 8; apoE with respective compound, n = 8) and receive for 8 weeks either a standard rodent chow (containing 4 % fat and 0.001 % cholesterol) or a standard rodent chow + respective compound (30 mg/kg/d p.o.). Mice are anesthetized with sodium pentobarbitone (100 mg/kg i.p.), and the hearts are rapidly excised and placed into ice-cold perfusion buffer. The aorta is cannulated and connected to a perfusion apparatus (Hugo Sachs Electronics, Freiburg, Germany) which is started immediately at a constant perfusion pressure of 60 mm Hg. Hearts are perfused in a retrograde fashion with modified Krebs bicarbonate buffer, equilibrated with 95 % 02 and 5 % C02 and maintained at 37.5 °C. A beveled small tube (PE 50) is passed through a pulmonary vein into the left ventricle and pulled through the ventricular wall, anchored in the apex by a fluted end, and connected to a tip-micromanometer (Millar 1.4 French). The left atrium is cannulated through the same pulmonary vein and the heart switched to the working mode with a constant preload pressure of 10 mm Hg and an afterload pressure of 60 mm Hg. Aortic outflow and atrial inflow are continuously measured using ultrasonic flow probes (HSE/Transonic Systems Inc.). Coronary flow is calculated as the difference between atrial flow and aortic flow. All hemodynamic data are digitized at a sampling rate of 1000 Hz and recorded with a PC using spezialized software (HEM, Notocord).
Hearts are allowed to stabilize for 30 min. All functional hemodynamic data are measured during steady state, and during volume- and pressure loading.
Left ventricular function curves are constructed by varying pre-load pressure. For acquisition of preload curves, afterload is set at 60 mm Hg and preload is adjusted in 5 mm Hg steps over a range of 5 to 25 mm Hg. Hearts are allowed to stabilize at baseline conditions between pressure- and volume-loading.
