The present invention relates to novel nitrate ester derivatives of substituted amino-alcohols, to methods for their preparation and to their use in cardiovascular diseases, in particular in high blood pressure and vascular and organ damage accompanying high blood pressure. The derivatization of aminoalcohol-based renin inhibitors to give the corresponding nitrate esters leads to compounds having unexpectedly strong hypotensive and tissue-protecting properties, which go beyond the inhibition of renin.
Cardiovascular diseases and further organ damage are the most frequent consequences of untreated or inadequately treated high blood pressure. Thus, high blood pressure in the long term leads to overloading of the heart and vessels and, accompanying this, an increased risk of developing cardiovascular disease and organ damage. Typical consequences are arterial occlusive diseases, cardiac infarct, stroke and kidney damage. In the presence of diabetes or risk factors such as smoking and overweight, the risk of suffering one of these high blood pressure sequelae grows.
In many clinical morbidity and mortality studies, the benefit of an intensive medicinal blood pressure treatment was shown. These studies also showed that therapeutic classes over and beyond lowering of blood pressure can differ in their tissue and organ protection. These distinctions were explained by pleiotropic therapeutic effects. Inhibitors of the renin-angiotensin system, such as angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARB), were, for example, ascribed anti-inflammatory, anti-proliferative and antithrombotic properties. These properties could be particularly well shown with renin inhibitors and were described, for example, in WO2005/090305.

The compounds of the formulae (I) and (II) can be prepared in an analogous manner to preparation processes known from the literature. Similar preparation processes are described, for example, in EP 678503, WO2005/070870, WO2005/070871, WO2005/070877 and WO2005/090305. Details of the specific preparation variants can be taken from the examples.
The compounds of the formulae (I) and (II) can also be prepared in optically pure form. Separation into antipodes can be carried out by methods known per se either preferably in an early stage in the synthesis by salt formation with an optically active acid such as, for example, (+)- or (−)-mandelic acid and separation of the diastereomeric salts by fractional crystallization or preferably in a rather late stage by derivatization with a chiral auxiliary structural unit such as, for example, (+)- or (−) camphanyl chloride, and separation of the diastereomeric products by chromatography and/or crystallization and subsequent cleavage of the bond to the chiral auxiliary. The pure diastereomeric salts and derivatives can be analysed using customary spectroscopic methods for determination of the absolute configuration of the piperidine contained, X-ray spectroscopy on single crystals being a particularly suitable method.
The compounds of the formulae (I) and (II) also include those compounds in which one or more atoms are replaced by their stable, non-radioactive isotopes; for example a hydrogen atom by deuterium.
Prodrug derivatives of the compounds presently described are derivatives thereof which in in vivo use release the original compound by means of a chemical or physiological process. A prodrug can be reacted, for example, to give the original compound on achieving a physiological pH or by enzymatic conversion. Prodrug derivatives can be, for example, esters of freely available carboxylic acids, S- and O-acyl derivatives of thiols, alcohols or phenols, the acyl group being defined as presently. Pharmaceutically usable ester derivatives, which can be reacted by solvolysis in physiological medium to give the original carboxylic acid, such as, for example, lower alkyl esters, cycloalkyl esters, lower alkenyl esters, benzyl esters, mono- or disubstituted lower alkyl esters, such as lower ω-(amino, mono- or dialkylamino, carboxyl, lower alkoxycarbonyl)alkyl esters or such as lower α-(alkanoyloxy, alkoxycarbonyl or dialkylaminocarbonyl)alkyl esters are preferred; those utilized are conventionally pivaloyloxymethyl esters and similar esters.
On account of the close relationship between a free compound and a salt compound, a certain compound in this invention also comprises its salt form, if this is possible and appropriate.
The compounds of the formula (I) or (II), in particular the compounds illustrated in Examples 1-48 and their pharmaceutically usable salts show extended properties in that on the one hand they release nitrogen monoxide and on the other hand either directly inhibit the natural enzyme renin as illustrated by the Examples 1-36 or inhibit renin indirectly upon drug metabolism as illustrated by the Examples 37-48. The release of nitrogen monoxide and its pharmacokinetic distribution in the living organism resulted in unexpectedly useful pharmacological properties, which can be explained as follows.
The juxtaglomerular cells of the kidney secrete the enzyme renin into the systemic circulation, where renin proteolytically cleaves the substrate angiotensinogen into the decapeptide product angiotensin I. Angiotensin I is further processed proteolytically by the angiotensin-converting enyzme to the octapeptide angiotensin II. Angiotensin II increases the blood pressure by causing arterial vasoconstriction by receptor binding and a decrease in sodium excretion. Moreover, angiotensin II increases the activity of NADPH oxidase and thus leads to the breakdown of nitrogen monoxide, which leads to a decrease in endothelium-dependent vascular relaxation, to hypertrophy, proliferation and migration of the smooth muscle cells, to the formation of extracellular matrix, and to thrombotic and inflammatory reactions.
The inhibition of the enzymatic renin activity leads to decreased formation of angiotensin I and thus to the lowering of the angiotensin II content.
The suppression of angiotensin II formation leads to a decrease in the arterial blood pressure and to the prevention of blood pressure-dependent and blood pressure-independent tissue damage.
Nitrogen monoxide has the property of reversibly activating soluble guanylate cyclase, a widespread enzyme which can be found in the cells of any organ system. In this process, nitrogen monoxide binds to the haem-containing domain group of the enzyme, by means of which its catalytic activity, which converts guanosine triphosphate to cyclic guanosine monophosphate, is increased. Increased concentrations of cyclic guanosine monophosphate relax the smooth muscle cells in the venous and, in some cases, arterial blood vessels, in the heart, in the intestine, in the urogenital tract, in the airways and in the uterus; they moreover inhibit the aggregation and adhesion of platelets and block the accumulation of leucocytes on the vessel walls. These effects, so it is believed, explain the vasculoprotective contributions of nitrogen monoxide. In fact, virtually any cardiovascular risk factor, such as, for example, high blood pressure, diabetes, hyperlipidaemia and smoking can be connected with a decrease in the basal and in the stimulated nitrogen monoxide-induced vascular relaxation.
The invention described herein makes available a new therapeutic approach for high blood pressure and blood pressure-dependent and blood pressure-independent diseases in that the compounds of the formulae (I) and (II) on the one hand inhibit high blood pressure-promoting and tissue-damaging renin and on the other hand release tissue-relaxing and tissue-protecting nitrogen monoxide. Pharmacologically, the compounds of the formulae (I) and (II) allow the relaxation of the arterial and of the venous blood vessels by systemic distribution of the compounds and thus systemic renin inhibition and nitrogen monoxide release. In contrast to the separate use of both active principles, i.e. of a renin inhibitor and of a nitrogen monoxide-releasing substance, the compounds of the invention described herein allow a uniform systemic distribution and thus a balanced effect on blood and blood vessels, blood pressure and tissue.
The pharmacological profile of the compounds of the formulae (I) and (II) can be worked out using the following system. The in vitro test systems described herein allow, independently of one another, the direct determination of the renin-inhibiting properties and the nitrogen monoxide-releasing properties of a compound. The in vivo test systems described herein allow the determination of the combined effect of renin inhibition be it occurring directly or upon drug metabolism and nitrogen monoxide release on the blood pressure and on tissue functions.
In order to distinguish the blood pressure-lowering and tissue-protecting contributions of renin inhibition from nitrogen monoxide release of an orally administered compound, the blood pressure lowering and tissue function of a nitrate ester compound are compared with the nitrate-free parent substance with equal pharmacokinetic distribution. If the release of the nitrogen monoxide does not take place or takes place in a pharmacologically unsuitable manner, no additional blood pressure lowering or no tissue protection can be shown. If, however, the pharma-cokinetic release and distribution, for probably not conclusively explainable reasons, take place on the nitrogen monoxide-sensitive and blood pressure-regulating tissues, as shown presently an additional blood pressure-lowering or tissue protection of the heart and kidneys can be functionally shown.
The determination of the direct renin-inhibiting properties of a compound can be carried out using in vitro enzymatic test systems. The in vitro test systems determine the formation of angiotensin I from natural or recombinant renin substrate in the presence of human plasma samples or purified renin enzyme. A frequently used in vitro test system has been described by Nussberger et al. (1987) in J. Cardiovascular Pharmacology, Vol. 9, pp. 39-44. The test quantitatively determines the formation of angiotensin I in human plasma in the presence or absence of renin inhibitors in various concentration ranges. The angiotensin I concentrations produced are measured by a radioimmuno investigation.
The compounds of the present invention, particularity the compounds illustrated in Examples 1-36, showed in these in vitro test systems direct renin-inhibiting actions in minimal concentration ranges from 10−10 to 10−7 mol/l. The efficacy of the compounds can be expressed using IC50 values, which represent the concentration of a certain compound which suppresses the angiotensin I content by 50%. The IC50 values of the compounds obtained were in the range from 0.1 nM to 100 nM, the majority of these in the range from 1 nM to 10 nM. Certain nitrate ester compounds showed similar, i.e. higher, identical or alternatively lower, IC50 values in comparison with their nitrate-free parent substances.
The determination of the nitrogen monoxide-releasing properties of a compound, be it by enzymatic or non-enzymatic action, can be carried out by means of in vitro vascular reactivity tests. The in vitro vascular reactivity test measures the ability of the released nitrogen monoxide to relax a pretensioned aorta ring or vein ring which is kept in an organ chamber. Frequently used instructions are described by Gonzales et al., in Adv. Physiol. Educ. (2000) 24:13-21. The thoracic aorta or the femoral vein is isolated from sacrificed and exsanguinated Wistar rats and cut up to give rings 2 mm long. The arterial rings are stored in organ chambers. Changes in the development of tension after the action of compounds are recorded by an isometric signal transmitter, which is connected to a computerized detection system. The computer program analyses time curves, period and size amounts between contractions. The test compounds described here showed vessel-relaxing actions in phenylephrine-precontracted vessels in concentration ranges of approximately 10−9 to 10−4 mol/l. The nitrogen monoxide-induced vessel-relaxing activity of the compounds can be expressed in percentage points of the maximal vessel relaxation achieved with sodium nitroprusside (SNP) relative to the phenylephrine (0.1 μM)-induced contractile tone.
The determination of the in vitro inhibition of platelet aggregation (IPA) by nitrogen monoxide can be carried out using the following test system. Platelet-enriched plasma is obtained from rat blood by centrifugation. The aggregability of the platelets can be measured optically using a turbidimetric aggregometer. The aggregation-inhibiting action of the compounds of the formulae (I) and (II) can be determined relative to aggregation-stimulating agents using adenosine diphosphate (ADP). The test compounds (10-500 μM) can be added to the platelet solution here 1-5 minutes before introduction of ADP (1-10 uM). The optical density determined in the test system determines the degree of platelet aggregation.
The compounds of the formulae (I) and (II) led to a decrease in the ADP-induced platelet aggregation. The percentage decrease was between 20 and 60%.
The in vivo blood pressure-lowering actions of the compounds of the formulae (I) and (II) can be shown in doubly transgenic rats (dTGR), which overexpress both the gene for human angiotensinogen and the gene for human renin and as a result of this develop hypertension; Blood pressure values and heart rate values can be determined continuously, for example, by means of chronically implanted telemetry equipment. A telemetry system can consist of a radio frequency transmitter, a receiver apparatus and a data collection system. The pressure transmission catheter of the pressure sensor can be implanted into the abdominal aorta. After the operation, the rats are allowed a recovery period of 7 days, where the telemetry recording should indicate the restoration of a 24 hour oscillation rhythm of blood pressure and heart rate before compounds can be tested.
Compounds of the formulae (I) and (II) can be administered orally by means of stomach tubes. Blood pressure changes can be recorded over 24 hours after a single dosage or continuously over 2 to 42 days after multiple dosage. The dose administered, consisting of vehicle-suspended or dissolved compound, is in the range from 0.5 mg/kg of body weight up to 100 mg/kg of body weight. Blood pressure changes can be expressed by means of mean arterial blood pressure values (MAP), in order to describe the average pressure within a cardiac cycle.
The use of the compounds of the formulae (I) and (II) resulted in lowerings of mean arterial blood pressure (MAP) of 20 to 70 mmHg. Moreover, certain nitrate ester compounds showed greater lowerings of blood pressure in comparison to their nitrate-free parent compounds.
The pharmacokinetic distribution of a compound of the formula (I) or (II) can be determined by comparison of the time-dependent plasma concentrations of a compound after oral or intravenous administration to a living organism such as, for example, a mouse, a rat or a dog. The doses used for oral administration range from 0.5 to 50 mg/kg of body weight; for intravenous administration doses of 0.5 to 20 mg/kg of body weight are administered. For intravenous use, the usable formulation of a compound can be administered to groups of three to eight animals, for example, to the caudal vein of a rat and, for oral use, by means of a stomach tube. Ethically justifiable blood sample volumes can be taken from the animals, according to a suitable time pattern, for example automatically by means of an AccuSampler (DiLab Europe, Lund, Sweden), and transferred to heparinized containers. Plasma samples produced are stored, up to the determination of the concentration of a compound contained, for example by liquid chromatography and mass spectral analysis, at −17 to −23° C. Compounds of the formulae (I) and (II) showed absolute bioavailabilities in the range from 10-50% and elimination half-lives of 2-12 h. The plasma levels of a compound can also be expressed by area under the curve (AUC) values, which allow an additional comparison of the compounds. Thus, compounds of the formulae (I) and (II) show AUC values in the range from 500 to 15 000 ng×h/ml.
The influencing of the coronary flow and anti-ischaemic effects of the compounds of the formulae (I) and (II) can also be measured in vivo by means of a perfusion model. For this, the heart is removed from the rats pretreated with the compounds of the formulae (I) and (II) after anaesthesia and this is mounted in a Langendorff apparatus after cannulation of the aorta, whereby it can be supplied with oxygen-rich perfusate. After tying off the vena cava and pulmonary veins, and the cannulation of the pulmonary artery, the coronary flow can be determined by means of a flow meter. The coronary flow was measured volumetrically and expressed as the millilitres of perfusate which are collected in one minute. The coronary flow can be measured before and after induction of ischaemia, ischaemia being initiated by interruption of the perfusion for 30 minutes and a 30-minute reperfusion period following after opening of the flow. Thus the coronary flow in the reperfusion period can be compared with that in the pre-ischaemic period. Compounds of the formulae (I) and (II) are thereby able to increase the coronary flow by 50-200%.
The tissue-protecting action of a compound of the formula (I) and (II) after long-term use can be determined in vivo by proteinuria and kidney function measurements, as indicators of kidney damage. The investigations can be carried out in 4-week-old, male rats, for human renin and angiotensinogen doubly transgenic rats (dTGR). The animals are divided into treatment groups and are given drug, comparison substance or vehicle (control) for 7 weeks. The dose used for oral administration can range from 0.5 to 100 mg/kg of body weight. During the entire study period, the animals are given standard feed and tap water ad libitum. The animals are placed in a metabolic cage once weekly in order to determine the 24-hour albumin excretion (AE) in the urine, diuresis, natriuresis and urine osmolality. Moreover, the kidneys can be functionally investigated by determining the glomerular filtration rate, for example using the iohexyl method, creatinine excretion, for example by means of the plasma creatinine concentration, and the renal perfusion rate, for example using the para-aminohippurate method. At the end of the study, the animals are sacrificed and the kidneys and hearts are removed for weight determination and immunohistological investigations (tissue fibrosis, leucocyte infiltration, inflammation markers etc.). The extent of tissue fibrosis can be shown, for example, with the following polyclonal antibodies: anti-fibronectin, anti-collagen IV. The extent of cell infiltration can be shown, for example, with the following monoclonal antibodies: anti-CD4, anti-CD8, anti-ED1, anti-MHCII, anti-CD68 and anti-Ox6. As inflammation markers, immunologically captured TGFβ, MCP-1, TNFα or IL-6 can be used. The semiquantitative evaluation of various kidney and heart sections showed a decrease in tissue fibrosis and tissue inflammation after use of the compounds of the formulae (I) and (II).

In order to achieve the desired effects in a patient to be treated, the compounds of the present invention can be administered orally or enterally, such as, for example, intravenously, intraperitoneally, intramuscularly, rectally, subcutaneously or alternatively by direct injection of the active agent locally into tissue or tumours. The term patient paraphrases warm-blooded animals and mammals, such as, for example, humans, primates, cattle, dogs, cats, horses, sheep, mice, rats and pigs. The compounds can be administered as a pharmaceutical preparation or incorporated into an administration device which guarantees lasting effusion of the compound. The amount of substance to be administered can vary over a wide range and can be any effective dose. Depending on the patient to be treated or condition to be treated and type of administration, the dose of the effective active agent can be between approximately 0.005 and 50 milligrams per kilogram of body weight daily, but preferably between approximately 0.05 and 15 milligrams per kilogram of body weight daily.
For oral administration, the compounds can be formulated in solid or liquid pharmaceutical forms such as, for example, as capsules, pills, tablets, coated tablets, granules, powders, solutions, suspensions or emulsions. The dose of a solid pharmaceutical form can be an ordinary hard gelatin capsule, which can be filled with active agents and excipients, such as lubricants and fillers, such as, for example, lactose, sucrose and maize starch. A further administration form can be the tabletting of the active substance of the present invention. The tabletting can be carried out with conventional tabletting auxiliaries such as, for example, lactose, sucrose, maize starch, combined with binders consisting of acacia gum, maize starch or gelatin, disintegrants such as potato starch or cross-linked polyvinylpyrrolidone (PVP) and lubricants such as stearic acid or magnesium stearate. Suitable excipients for soft gelatin capsules are, for example, vegetable oils, waxes, fats, semisolid and liquid polyols etc. Suitable excipients for the preparation of solutions and syrups are, for example, water, polyols, sucrose, invert sugar, glucose etc.
For rectal administration, the compounds can be formulated in solid or liquid pharmaceutical forms such as, for example, suppositories. Suitable excipients for suppositories are, for example, natural or hardened oils, waxes, fats, semiliquid or liquid polyols etc.
For parenteral administration, the compounds can be formulated as an injectable dose of the active agent in a liquid or suspension. The preparations usually contain a physiologically tolerable sterile solvent, which can contain a water-in-oil emulsion, with or without surfactant, and other pharmaceutically acceptable excipients. Oils which can be used for preparations of this type are paraffins and triglycerides of plant, animal or synthetic origin, such as, for example peanut oil, soya bean oil and mineral oil. In general, injectable solutions contain liquid carriers such as more preferably water, common salt, dextrose or related sugar solutions, ethanol and glycols, such as propylene glycol or polyethylene glycol.
The substances can be administered as a transdermal patch system, as a depot injection or implant if the formulation makes possible a lasting release of the active agent. The active agent can be compressed as granules or to give narrow cylinders and can be administered subcutaneously or intramuscularly as a depot injection or implant.
In addition, the pharmaceutical preparations can further contain preservatives, solubilizers, viscosity-increasing substances, stabilizers, wetting agents, emulsifiers, sweeteners, colourants, flavourings, salts for alteration of the osmotic pressure, buffers, coating agents or antioxidants. They can also contain other therapeutically valuable substances.
