Description: 1,4-DIHYDROPYRIDINES AS BRADYKININ ANTAGONISTS This invention relates to 1 ,4-dihydropyridine compounds. These compounds are useful as antagonists of bradykinin, and are thus useful in the treatment of inflammation, asthma, allergic rhinitis, pain or the like in mammals, including humans. The present invention also relates to pharmaceutical compositions containing such compounds and to the use of such compounds in the treatment and prevention of inflammation, asthma, allergic rhinitis, pain and other disorders. Bradykinin ("BK") is generated under normal conditions in mammals by the action of various plasma enzymes such as kallikrein on high molecular weight kininogens. It is widely distributed in mammals, as are its two receptor subtypes, B^ and B 2 . The actions of BK at the B 2 receptor include mainly contraction of arterial and venous preparations, although it can cause relaxation of peripheral resistance vessels as well. Many of the more important functions of BK, such as increases in vascular permeability, pain, and vasodilatation, however, are mediated by the B 2 receptor. These effects at the B 2 receptor are believed to be responsible for BK's role in numerous diseases, such as inflammation, cardiovascular disease, pain, and the common cold. Hence antagonists at the B 2 receptor should find considerable therapeutic applications. Most of the efforts in this area thus far have been directed at peptidic analogues of the BK structure, some of which have been studied as analgesics and antiinflammatory agents. Numerous 1 ,4-dihydropyridine compounds which are B 2 antagonists have been synthesized and disclosed in a number of patent publications such as US 5861402, EP 899261A1 and WO 97/30048. International Publication Number WO 96/06082 discloses a variety of 1 ,4- dihydropyridine compounds having a piperazinylcarbonylmethy group at the 2-position, which compounds are antagonists of bradykinin. It would be desirable if there were provided a non-peptide antagonist against the B 2 receptor, having potent B 2 antagonistic activity without metabolic liability or drug-drug interactions, especially inhibition of P-450 isozymes such as CYP3A4.

Detailed Description of the Invention The 1 ,4-dihydropyridine compounds of formula (I) of this invention may be prepared by a variety of synthetic methods known to those skilled in the art. For example, the 1 ,4-dihydropyridine compounds of formula (I), may be prepared by reaction of compound (II) with compound (III), followed, if desired, by conversion of a compound (III) in which R 3 is H into a compound (III) in which R 3 is other than H, as indicated in the following Preparation Method A. Preparation Method A: (wherein Z is hydrogen or lower alkyl (e.g., CM alkyl) such as methyl and ethyl; and the other symbols are as already defined) In Preparation Method A, when Z is lower alkyl, the compound (II) may be first subjected to selective saponification of the ester residue at the 2-position of the dihydropyridine ring, followed by acidification to afford a free acid, which is coupled with the compound (III) to give the 1 ,4-dihydropyridine (I). When Z is H, the compound (II) may be directly coupled with the compound (III) to obtain the 1 ,4-dihydropyridine (I). The selective saponification and the acidification may be carried out by conventional procedures. In a typical procedure, the selective saponification is carried out by treatment with sodium hydroxide in a suitable reaction-inert solvent at a temperature in the range from - 20 to 40°C, usually from 10°C to 30°C for 3 minutes to 4 hours, usually 15 minutes to 1 hour. In a typical procedure, the acidification is carried out by treatment with diluted hydrochloric acid in a suitable reaction-inert solvent such as water at a temperature in the range from 0 to 30°C, usually from 5°C to 25°C for 1 minute to 1 hour, usually 5 minutes to 15 minutes. The 1 ,4-dihydropyridine (I) can be obtained from the corresponding 1 ,4- dihydropyridine (II) wherein R 3 is H by a coupling reaction between the obtained acid and 4- N-substituted piperazine. The condensation may be carried out in a reaction-inert solvent such as aqueous or non-aqueous organic solvents (e.g., tetrahydrofuran, DMF, dioxane, acetone, dimethoxyethane and acetonitrile); halogenated hydrocarbons such as chloroform, dichloromethane and dichloroethane (preferably dichloromethane) using a coupling agent such as dicyclohexylcarbodiimide (DCC), water soluble carbodumide (WSC), 2-ethoxy-N- ethoxycarbonyl-1 ,2-dihydroquinoline, benzotriazol-l-yloxy-tris(dimethylamino) phosphonium hexafluorophosphate (BOP), diethyl azodicarboxylate-triphenylphosphine, diethylcyanophosphonate (DEPC), diphenylphosphorylazide (DPPA), bromotripyrrolidino phosphonium hexafluorophosphate (PyBropftrademarkj), bis(2-oxo-3-oxazolidinyl) phosphinic chloride (BOPCI), benzotriazole-1 -yl-oxy-tris-pyrrolidino-phosphonium hexafluorophosphate(PyBOP), 2-(1-H-benzotriazole-1-yl)-1 ,1 ,3,3,-tetramethyluronium hexafluorophosphate (HBTU) and ethyl chloroformate. This reaction may be carried out at a temperature in the range from -30 to 40 °C, usually from 0°C to 25°C for 10 minutes to 96 hours, usually 30 minutes to 24 hours. In addition, when R 3 is substituted-alkyl, the 4-N-substituted piperazines (III) as used herein may be either known or may be prepared by known methods. For example, the 4-N- substituted piperazines may be prepared by means of (1) N-alkylation of 1-N-protected piperazine with appropriate alkyl halide, R 3 -halo, (2) reductive amination of 1-N-protected piperazine with appropriate aldehyde or ketone in the presence of a reducing agent, followed by deprotection of the 1 -N-protecting group, or (3) Michael addition of 1-N-protected piperazine with appropriate conjugated ketones, esters or amides, or (4) piperazine ring construction from N-substituted amine. Suitable 1 -N-protecting groups include, for example, benzyl, benzyloxycarbonyl and t-butoxycarbonyl group. The reductive alkylation may be carried out with appropriate aldehyde or ketone in a suitable reaction-inert solvent such as aqueous or non-aqueous organic solvents (e.g., tetrahydrofuran, dioxane, acetone, dimethoxyethane and acetonitrile); halogenated hydrocarbons such as chloroform, dichloromethane and dichloroethane (preferably dichloromethane), in the presence of a suitable reducing agent such as sodium borohydride, sodium cyanoborohydride or sodium triacetoxy borohydride at a temperature in the range from -20 to 120 °C, usually 0 to 80 °C for 10 minutes to 1 week, usually 30 minutes to 96 hours, optionally in the presence of molecular sieves. Alternatively, alkylation can be made by two step synthesis. A ketone may be treated with an amine in an inert solvent such as toluene or xylene, at a temperature in the range from 80 to 130°C, usually 100 to 120°C for 10 hours to 2 week, usually 1 days to 1 week, preferably 3 to 5 days. The product may be reduced by hydrogenation in the presence of appropriate catalyst such as palladium on carbon and platinum oxide(IV), usually platinum oxide(IV) in an inert solvent such as ethanol and ethyl acetate, usually ethyl acetate, at a temperature in the range from 10 to 60 G C, usually 20 to 30 °C for 1 hour to 3 days, usually 3 hours to 10 hours. Typical Micheal addition reaction may be carried out at a temperature in the range from 30°C to 120 °C, usually from 60°C to 100°C for 5 hours to a week, usually 10 hours to 4 days. Preparation Method B-l: (VII) (V) (wherein Z is lower alkyl such as methyl and ethyl; and the other symbols are as already defined) Scheme B-l This method utilizes the modified Hantzsch synthesis as described in A. Sausins and G. Duburs, Heterocycles, 1988, 27, 269. In this method, beta-keto ester (V) is first reacted with substituted benzaldehyde (VI) to obtain compound (VII).

If desired, this reaction may be catalyzed by a base such as piperidine, pyridine or alkoxide, or by an acid catalyst such as acetic acid, TiCI 4 or p- toluenesulfonic acid. Thereafter, the benzylidene (VII) as obtained above is reacted with enamine (VIII) in the presence of, or absence of a suitable condensing agent such as Lewis acids, to obtain the 1 ,4-dihydropyridine (II). This reaction may be carried out in the presence of, or absence of the reaction-inert solvent as listed above. However, this reaction may preferably carried out in the absence of a solvent. This reaction may be carried out at a temperature of 0 °C to 200 °C, preferably, from 60 °C to 150 °C for 30 minutes to 48 hours, preferably 10 hours to 20 hours. In addition, the beta-keto esters (V) which can be used herein may be prepared by known methods as shown in, for example: (1) J. Labelled Compds. Radiopharm., 1989, 27, 599; (2) J. Org.

Preparation Method B-ll: * * Compound (II) (V) (VIII) (wherein all the symbols are as already defined) Scheme B-II This method utilizes the three components Hantzsch reaction. In a typical procedure, the beta-keto ester (V), the substituted benzaldehyde (VI) and the enamine (VIII) may be heated together in a suitable reaction-inert solvent as listed above (preferably lower alkanols such as methanol and ethanol). Preferably, a small amount of a lower alkanoic acid such as acetic acid is added as catalyst. The reaction mixture may be heated at 80 °C to 200 °C, preferably from 100 °C to 140 °C for 30 minutes to 1 week, usually 24 hours to 96 hours. Preparation Method B-lll: Compounds of formula (VIII) may be prepared by a process of this invention according to Scheme B-lll. Compound (II) (VII) Scheme B-lll Scheme B-lll exemplifies a process of this invention for preparing a compound of formula (II) comprising step (a): addition of an enamine compound of formula (VIII) to an alkylene compound of formula (VII) followed by step (b) acid catalyzed cyclization reaction of the resulting compound in step (a). The former addition step (a) may be carried out under conditions applied to nucleophilic addition reactions using a suitable base in a reaction inert solvent. More preferably, the reaction may be carried out under conditions commonly used in Michael-type addition. Preferred bases for this reaction are those used in Michael-type reactions. Examples of the preferred bases include alkylmagnesium halides known as Grignard reagents and halomagnesium alkoxides. More preferred bases include (Cr C 6 )alkylmagnesium bromide and ferf-butoxy-magnesium bromide. Preferred solvents used in this reaction include (C C 4 )alkanol, tetrahydrofuran (THF), diethyl ether, dioxane, hexane, toluene, 1 ,2-dimethoxy ethane (DME) and the like. This reaction may be carried out at a temperature from about -150°C to reflux, preferably from about -100° to 100°C. In view of convenience, this reaction may be carried out at about room temperature using, for example, halomagnesium(d-C 4 )a!koxides, (Cι-C 6 )alkylmagnesiumhalides, metalhydrides, metal(d- C 3 )alkoxides, magnesium-di[(C C 3 )alkoxides], metal-n-butoxide, metal-sec-butoxide, metal- terf-butoxide or a metalcarbonate such as K 2 C0 3 . In case of the base is K 2 C0 3 , the reaction is effectively run in THF. In case of the base is CsF or KF, the reaction is effectively run in THF or methanol (MeOH) at an elevated temperature such as at about 60°C. In case of using butyllithium (BuLi), the reaction is effectively run in THF at from about -78° to about -30°C. In case of using halomagnesium(C C 4 )alkoxides or (Cι-C 6 )alkylmagnesiumhalides, a preferred solvent is THF. Suitable reaction time ranges from about 3 minutes to about 2 days, preferably from about 30 minutes to about 40 hours. The subsequent cyclization process step (b) may be carried out in the presence of a protonic acid. Suitable protonic acids include (C C 6 )alkanoic acid such as acetic acid, hydrochloric acid (HCl) and sulfonic acids such as p-toluenesulfonic acid. It is preferred to add a non-protonic Lewis acid to the reaction mixture in combination with the protonic acid, when the base used in Step (a) is other than magnesium (VIII) bases. This reaction may be carried out at a temperature from about -150°C to reflux, preferably from about -100° to 100°C. The reaction time ranges from about 1 second to 5 days, preferably 5 minutes to 20 houres. Generally, those reactions illustrated in Scheme B-l II may be carried out at about - 78°C using dry-ice/acetone or dry-ice/methanol, about 0°C using an ice-bath, room temperature or 100°C, preferably at about 0°C or about room temperature. The reaction steps (a) and (b) are performed in the same reaction vessel under mild conditions with high-yield. An enamine compound of formula (VIII) may be prepared according to procedures known to those skilled in the art, such as those illustrated in Scheme B-lll-a. (Vlll-P) (VIII) Scheme B-lll-a Typically, a beta-keto ester compound of formula (Vlll-P) may be transformed to a compound of formula (VIII) wherein R 2 , R 5 and Z are defined as above. This reaction may be carried out in a reaction inert solvent resolving ammonia gas at a temperature in the range of from about 0° to 60°C. Suitable reaction inert solvents include lower alkanols such as methanol and ethanol. Alternatively, an ammonia gas containing solution given above may be added to a solution containing a beta-keto ester (Vlll-P). The mixture is reacted at a temperature in the range of from about 0 to 60 °C to yield the enamine compound (VIII). More conveniently, the compund of formula (VIII) may be synthesized by a reaction of the compound of formula (VIII-P) with ammonium hydrogencarbonate or ammonium acetate in a reaction inert solvent or neat at in a range of ambient temperature to 120 °C, preferablly, at 30 to 80°C. Suitable reaction inert solvents include lower alkanols, such as methanol and ethanol, DMF , CH 3 CN or DMSO, but more easily the reaction may be run without solvent. An alkylene compound of formula (VII) may be prepared according to procedures known to those skilled in the art. Scheme B-lll-b illustrates one embodiment of the preparation process. (V) (VII) Scheme B-lll-b A carbonyl compound of formula (V) may be subjected to a coupling reaction with an aldehyde compound of formula (VI) to give the alkylene compound of formula (VII) according to a known procedure. For example, a compound of formula (V) may be reacted with a compound of formula (VI) according to a procedure reported by L. Tietze et al. Liebigs Ann. Chem., pp. 321-329, 1988. This reaction may be carried out in a suitable reaction inert- solvent for example an aromatic hydrocarbon such as benzene, toluene and xylene, an alcohol such as methanol, ethanol, propanol and butanol, an ether such as diethyl ether, dioxane and tetrahydrofuran (THF), a halogenated hydrocarbon such as methylene dichloride, chloroform and dichloroethane, an amide such as Λ/,Λ/-dimethylformamide (DMF), and a nitrile such as acetonitrile. This reaction may be carried out at a temperature in a range of from about 0°C to the reflux temperature of the reaction mixture, preferably from about 80° to the 120°C for from about 30 minutes to 24 hours, preferably from 30 minutes to 6 hours. This reaction may conveniently be carried in the presence of a base or acid catalyst. Suitable base catalysts are such as piperidine, pyridine and alkoxide, and suitable acid catalysts are such as acetic acid, TiCI 4 and p-toluenesulfonic acid. An intermediate compound of formula (V) may be prepared starting from a known compound according to a procedure known to those skilled in the art. For example, a compound of formula (V) may be prepared according to the procedure described in Scheme B-lll-c. R 4 — X' R 4 — CHO (V-3') (V-3 1 ) (wherein X' =halo or OTf) (V) Scheme B-lll-c An aldehyde compound (V-3), wherein R 4 is defined as above, is reacted with malonic acid under a basic condition. For example, this reaction may be carried out in the presence of a weak base such as piperidine in a reaction inert solvent such as pyridine to give a carboxylic acid compound of formula (V-2). Alternatively, the compound of formula (V- 2) may be synthesized by a so-called "Heck reaction". Thus, R 4 -X' (X -CI, Br, I, trifluoromethanesulfonate (OTf) may be reacted with acrylic acid in the presence of appropriate Pd catalyst in a reaction inert solvent, such as DMF, H 2 0, dimethylacetamide, N- ethylpiperidine, triethylamine, tributylamine, toluene, xylene, acetonitrile, 1 ,3-dimethyl-3,4,5,6- tetrahydropyrimidone, 1 ,3-dimethyl-2-imidazolinone, l-methyl-2-pyrrolidinone, tetrahydrofuran, dimethoxyethane, t-butylmethylether, dimethylsulfoxide, sulforane, preferably DMF, H 2 0 and tributylamine. The compound (V-2) thus obtained may be subjected to an aliphatic nucleophilic substitution reaction in the presence of a coupling agent to give a pentenoate compound of formula (V-1 ). This reaction may conveniently be carried out first by treating the compound of formula (V-1 ) with a coupling agent such as N,N'- carbonyldiimidazole in a reaction inert solvent such as dimethylformamide, then reacting with a neucleophilic reagent such as CH 3 0 2 CCH 2 COOK in the presence of a Lewis acid such as magnesium chloride. The former treatment may be carried out at a temperature in the range of 0° to 60°C, preferably at about room temperature for from about 1 minutes to 12 hours. The latter reaction may be carried out at the temperature in the range of from about 0° to 100°C, preferably from about room temperature to 60°C for from about 1 minutes to 12 hours. The compound of formula (V-1) may be reduced over a metal catalyst under hydrogen atmosphere to give the compound of formula (V) according to a known procedure. Suitable catalysts are such as Raney nickel catalyst and a noble metal catalysts including palladium on carbon and palladium hydroxide. This reaction may be carried out in a reaction inert solvent such as methanol, at about room temperature under hydrogen atmosphere at an appropriate pressure for about 1 minutes to 12 hours. Alternatively, a compund of formula (V) may be synthesized by reduction of a compund of formula (V-2) and following nucleophilic coupling of the resulting a compund of formula (V-1') with CH 3 0 2 CCH 2 COOK as indicated reaction condition above. Instead of the CH 2 =CH-COOH we can use CH 2 =CH-COO-R 1 etc. A ketone compound of formula (V) and a substituted benzaldehyde compound of formula (VI) may also be prepared according to known procedures (e.g., (1) D. Scherling, J. Labelled Compds. Radiopharm., Vol. 27, pp. 599-, 1989, (2) C. R. Holmquist et al., J. Org. Chem., Vol. 54, pp. 3528- , 1989, (3) S. N. Huckin et al., J. Am. Chem.

The reaction conditions similar to the above can be also used in this method. The enamine (IX) may either be known compounds or may be prepared by known methods. For example, the enamine (IX) may be prepared by reacting the beta-keto ester (V) with ammonia or ammonium salt. More specifically, the beta-keto ester (V) may be dissolved in a suitable solvent such as lower alkanols (ex. methanol and ethanol). Excess amount of ammonia gas is introduced into the solution at a temperature of 0 to 60 °C. Alternatively, a solution containing ammonia dissolved in the above solvent is added to the solution containing the beta-keto ester (V), and the resultant mixture is reacted at a temperature of 0 to 60 °C, to obtain the enamine (IX). More conveniently, the compund of formula (VIII) may be synthesized by a reaction of the compound of formula (VIII-P) with ammonium hydrogencarbonate or ammonium acetate in a reaction inert solvent or neat at in a range of ambient temperature to 120 °C, preferablly, at 30 to 80 °C. Suitable reaction inert solvents include lower alkanols, such as methanol and ethanol, DMF , CH 3 CN or DMSO, but more easily the reaction may be run without solvent. The compounds of formula (I), and the intermediates above-mentioned preparation methods can be isolated and purified by conventional procedures, such as recrystallization or chromatographic purification. General Synthesis of the optical active 1 ,4-dihydropyridine The optically active compounds of this invention can be prepared by several methods. For example, the optically active compounds of this invention may be obtained by chromatographic separation or fractional crystallization from the final compounds or the intermediates in racemic form thereof.

Preparation Method A-o: (wherein Z is hydrogen or lower alkyl (e.g., C M alkyl) such as methyl and ethyl; and the other symbols are as already defined) In Preparation Method A-l, when Z is lower alkyl, the compound (ll-o) may be first subjected to selective saponification of the ester residue at the 2-position of the dihydropyridine ring, followed by acidification to afford a free acid, which is coupled with the compound (III) to give the 1 ,4-dihydropyridine (l-o). When Z is H, the compound (ll-o) may be directly coupled with the compound (III) to obtain the 1 ,4-dihydropyridine (l-o). The selective saponification and the acidification may be carried out by conventional procedures. In a typical procedure, the selective saponification is carried out by treatment with sodium hydroxide in a suitable reaction-inert solvent such as methanol, dioxane and tetrahydrofuran (THF) at a temperature in the range from -20 to 40°C, usually from 10°C to 30°C for 3 minutes to 4 hours, usually 15 minutes to 1 hour. In a typical procedure, the acidification is carried out by treatment with diluted hydrochloric acid in a suitable reaction- inert solvent such as water at a temperature in the range from 0 to 30°C, usually from 5°C to 25°C for 1 minute to 1 hour, usually 5 minutes to 15 minutes. A compound (l-o) can be obtained from the corresponding compound (ll-o) wherein R 3 is H by a coupling reaction between the obtained acid and 4-N-substituted piperazine. The condensation may be carried out in a reaction-inert solvent such as aqueous or non-aqueous organic solvents (e.g., tetrahydrofuran, dioxane, acetone, DMF, dimethoxyethane and acetonitrile); halogenated hydrocarbons such as chloroform, dichloromethane and dichloroethane (preferably dichloromethane) using a coupling agent such as dicyclohexylcarbodiimide (DCC), water soluble carbodumide (WSC), 2-ethoxy-N- ethoxycarbonyl-1 ,2-dihydroquinoline, benzotriazol-l-yloxy-tris(dimethylamino) phosphonium hexafluorophosphate (BOP), diethyl azodicarboxylate-triphenylphosphine, diethylcyanophosphonate (DEPC), diphenylphosphorylazide (DPPA), bromotripyrrolidino phosphonium hexafluorophosphate (PyBrop[trademarkj) and ethyl chloroformate. This reaction may be carried out at a temperature in the range from -30 to 40 °C, usually from 0 °C to 25 °C for 10 minutes to 96 hours, usually 30 minutes to 24 hours. In addition, when R 3 is substituted-alkyl, the 4-N-substituted piperazines (III) as used herein may be either known or may be prepared by known methods. For example, the 4-N- substituted piperazines may be prepared by means of (1) N alkylation of 4-N-protected piperazine with appropriate alkyl halide, R 3 -halo, (2) reductive amination of 4-N-protected piperazine with appropriate aldehyde or ketone in the presence of a reducing agent, followed by deprotection of the amino-protecting group, or (3) Michael addition of 4-N-protected piperazine with appropriate conjugated ketone, ester or amide, or (4) piperazine ring construction from N-substituted amine. Suitable amino-protecting groups include, for example, benzyl, benzyloxycarbonyl and t-butoxycarbonyl group. The reductive alkylation may be carried out with appropriate aldehyde or ketone in a suitable reaction-inert solvent such as aqueous or non-aqueous organic solvents (e.g., tetrahydrofuran, dioxane, acetone, dimethoxyethane, acetonitrile, methanol and ethanol); halogenated hydrocarbons such as chloroform, dichloromethane and dichloroethane (preferably dichloromethane), in the presence of a suitable reducing agent such as sodium borohydride, sodium cyanoborohydride or sodium triacetoxyborohydride at a temperature in the range from -20 to 120 °C, usually 0 to 80 °C for 10 minutes to 1 week, usually 30 minutes to 96 hours, optionally in the presence of molecular sieves. Alternatively, alkylation can be made by two step synthesis. A ketone may be treated with an amine in an inert solvent such as toluene or xylene, at a temperature in the range from 80 to 130°C, usually 100 to 120°C for 10 hours to 2 week, usually 1 days to 1 week, preferably 3 to 5 days. The product may be reduced by hydrogenation in the presence of appropriate catalyst such as Palladium on carbon and platinum oxide (IV), usually platinum oxide in an inert solvent such as ethanol and ethyl acetate, usually ethyl acetate, at a temperature in the range from 10 to 60 °C, usually 20 to 30 °C for 1 hour to 3 days, usually 3 hours to 10 hours. Typical Micheal addition reaction may be carried out at a temperature in the range from 30 °C to 20 °C, usually from 60 °C to 100 °C for 5 hours to a week, usually 10 hours to 4 days. The optically active intermediates of formula (II) can be prepared by the following methods. Preparation Method B-l-o (Fractional Crystallization): (ll-c) (wherein [B 1 B 2 B ]NH + is a chiral amine residue; Z is hydrogen; R*COOH and R*S0 3 H are chiral acids and the other symbols are already defined.) In this method, an acid compound (ll-a) may be subjected to a fractional crystallization with a chiral amine such as cinchonidine, cinchonine, quinine, burcine and phenethylamine or their derivatives, amino acids to obtain an amine salt (ll-b). This reaction may be conducted in an organic solvent, preferably a pure or mixed alcoholic solvent selected from methanol, ethanol, 2-propanol and mixture thereof. The resulted salt may be further purified by several times recrystallization. The pure salt thus obtained may be converted to the corresponding carboxylic acid (an enantiomer of compound (II) wherein Z is H) by a partition between organic solvent such as ethyl acetate or dichloromethane and acid solution such as diluted hydrochloric acid followed by concentration. On the other hand, the salt of the antipode contained in the resulted mother liquid may be converted to the corresponding carboxylic acid (an enantiomer of compound (II) wherein Z is H) by the same procedure described above after concentration of the mother liquid. This acid may be further purified by crystallization in organic or inorganic solvents to give the antipode. This crystallization of the acid may be performed several times , if necessary, to improve its optical purity. Instead of R*COOH or R*S0 3 H, we can use phosphonic acid such as (R*0) 2 P(0)OH and R*0(R'0)P(0)OH. Furthermore, a final compound (l-a) may be resolved into each salt of both enantiomers by the same procedure described above using chiral acid. The resolved salts thus obtained may be converted to the corresponding amines (each enantiomer of l-a) by a partition between organic solvent such as dichloromethane and basic solution such as aqueous sodium hydrogencarbonate or sodium hydroxide. The preparation of other compounds of the formula (I), and intermediates thereof, not specifically described in the foregoing experimental section can be accomplished using combinations of the reactions described above that will be apparent to those skilled in the art. The isolation and purification of compounds of formula (I), and the intermediates shown in the above reaction schemes, not specifically described in the foregoing experimental section can be accomplished using conventional procedures, such as recrystallization or chromatographic separation. The compounds of formula (I) and their pharmaceutically acceptable salts can be administered to mammals, including humans, via either the oral, parenteral or topical routes. In general, these compounds are most desirably administered in doses ranging from about 0.3 mg to about 750 mg per day, preferably in doses ranging from about 10 mg to about 500 mg per day, in single or divided doses (Le^, from 1 to 4 doses per day), although variations will necessarily occur depending upon the species, weight and condition of the subject being treated, the disease state being treated and the particular route of administration chosen. For example, a dosage level that is in the range of from about 0.06 mg to about 2 mg per kg of body weight per day is most desirably employed for the treatment of inflammation. The compounds of the present invention may be administered alone or in combination with pharmaceutically acceptable carriers or diluents by either of the routes previously indicated, and such administration may be carried out in single or multiple doses. More particularly, the novel therapeutic agents of the present invention can be administered in a wide variety of different dosage forms, Le., they may be combined with various pharmaceutically acceptable inert carriers in the form of tablets, capsules, lozenges, troches, hard candies, powders, sprays, creams, salves, suppositories, jellies, gels, pastes, lotions, ointments, aqueous suspensions, iηjectable solutions, elixirs, syrups, and the like. Such carriers include solid diluents or fillers, sterile aqueous media and various nontoxic organic solvents, etc. Moreover, oral pharmaceutical compositions can be suitably sweetened and/or flavored. In general, the therapeutically-effective compounds of this invention are present in such dosage forms at concentration levels ranging from about 5% to about 70% by weight, preferably from about 10% to about 50% by weight. For oral administration, tablets containing various excipients such as microcrystalline cellulose, sodium citrate, calcium carbonate, dicalcium phosphate and glycine may be employed along with various disintegrants such as starch (and preferably corn, potato or tapioca starch), alginic acid and certain complex silicates, together with granulation binders like polyvinylpyrrolidone, sucrose, gelatin and acacia. Additionally, lubricating agents such as magnesium stearate, sodium lauryl sulfate and talc are often very useful for tabletting purposes. Solid compositions of a similar type may also be employed as fillers in gelatin capsules; preferred materials in this connection also include lactose or milk sugar as well as high molecular weight polyethylene glycols. When aqueous suspensions and/or elixirs are desired for oral administration, the active ingredient may be combined with various sweetening or flavoring agents, coloring matter or dyes, and, if so desired, emulsifying and/or suspending agents as well, together with such diluents as water, ethanol, propylene glycol, glycerin and various like combinations thereof. For parenteral administration, solutions of a compound of the present invention in either sesame or peanut oil or in aqueous propylene glycol may be employed. The aqueous solutions should be suitably buffered (preferably pH greater than 8) if necessary and the liquid diluent first rendered isotonic. These aqueous solutions are suitable for intravenous injection purposes. The oily solutions are suitable for intra-articular, intra-muscular and subcutaneous injection purposes. The preparation of all these solutions under sterile conditions is readily accomplished by standard pharmaceutical techniques well known to those skilled in the art. Additionally, it is also possible to administer the compounds of the present invention topically when treating inflammatory conditions of the skin and this may preferably be done by way of creams, jellies, gels, pastes, patches, ointments and the like, in accordance with standard pharmaceutical practice. Method for assessing biological activities: The activity of the compounds of formula (I) of the present invention, as bradykinin antagonists, is determined by their ability to inhibit the binding of bradykinin at its receptor sites in recombinant human bradykinin B 2 receptor expressing CHO-K1 cells (from Receptor Biology, Inc.) employing radioactive ligands. The bradykinin antagonist activity of the 1 ,4-dihydropyridine compounds is evaluated by using the standard assay procedure described in, for example, Baenziger N. L., Jong Y-J. I., Yocum S. A., Dalemar L. R., Wilhelm B., Vaurek R., Stewart J. M., Eur. J. Cell Biol., 1992, 58, 71-80. This method essentially involves determining the concentration of the individual compound required to reduce the amount of radiolabelled bradykinin ligands by 50% at their receptor sites in CHO-K1 cells, thereby affording characteristic IC 50 values for each compound tested. More specifically, the assay is carried out as follows. First, rat, guinea pig or monkey ileum tissues are minced and suspended in 25mM piperazine-N.N'-bis (2-ethanesulfonic acid (PIPES) buffer (pH 6.8) containing 0.1 mg/ml of soybean trypsin inhibitor. Then, the tissues are homogenized using a Polytron homogenizer at setting 7 for 30 seconds three times, and then rehomogenized with a Teflon-coated homogenizer. The homogenized suspension is centrifuged at 1 ,200 X g for 15 minutes. The pellet is rehomogenized and then centrifuged at 1 ,200 X g for 15 minutes. The supernatant is centrifuged at 10,000 X g for 60 minutes. The tissue pellets, CHO-K1 cell membrane are suspended in 25 mM PIPES buffer (pH6.8) containing 1.25 mM dithiothreitol, 1.75 μg/ml bacitracin, 1 mM o-phenanthroline, 18.75 μM captopril and 1.25 mg/ml bovine serum albumin (BSA), in order to prepare tissue/cell suspensions. Then, 10 μl of test compound solution dissolved in phosphate buffered saline (PBS, pH 7.5) containing 2% DMSO (final) and 0.1% BSA (w/v) or 10ml of 12.5 mM bradykinin in PBS (pH 7.5) containing 0.1% BSA (w/v) are placed in a reaction 96-well plate. 5 μl of 8.3 nM [3H]bradykiπin is added to the compound solution or bradykinin solution in the 96-well plate. Finally 100 μl of the tissue or cell suspension is added to the mixture in the plate, and incubated at room temperature for 1 hour in the absence of light. After incubation, the resultant product in the reaction plates is filtered through 0.1% polyethylenimine presoaked LKB filermat The filtrate is washed using a Skatron auto cell harvester. The tissue bound radioactivity is determined using a LKB betaplate counter. The IC 5 o value is determined using the equation: Bound=B max /(1+[l]/IC 50 ) wherein [I] means the concentration of the test compound. All compounds prepared in the Examples described below were tested by this method and showed an IC 50 value of 0.1 nM to 21 nM in CHO-K1 cells with respect to inhibition of binding at its receptor. The most preferred compounds prepared in the working examples as described below were tested by this method and showed an IC 50 value of 0.1 nM to 2.4 nM in CHO-K1 cells with respect to inhibition of binding at its receptor. The possibility of drug-drug interactions of the 1 ,4-dihydropyridine compounds of the present invention, as bradykinin antagonists, is determined by their ability to inhibit the testosterone 6β-hydroxylase activity raised by CYP3A4 which is the most abundant subtype of cytochrome P-450 in human. CYP3A4 interaction assay This method essentially involves determining the concentration of the individual compound required to reduce the amount of 6β-hydroxytestosterone by 50%. More specifically, the assay is carried out as follows. Human liver microsomes (0.2 mg/ml) are mixed with appropriate concentrations of kinin B2 antagonist. The mixture is then incubated in the presence of 50 μM testosterone, 1.3 mM NADP + , 0.9 mM NADH, 3.3 mM glucose-6-phosphate, 3.3 mM MgCI 2 , and glucose-6-phosphate dehydrogenase (8 units/ml) in a total volume of 0.2 ml of 100 mM potassium phosphate buffer, pH 7.4, at 37 °C. After incubation (20 minutes), 10 μl of methylalchol containing internal standard is withdrawn. The medium is filtrated by membrane filter with centrifugation at 1 ,800 x g for 10 minutes, and the resulting filtrate is removed. A 6β-hydroxylated metabolite of testosterone in samples is analyzed by HPLC. A sample of 20 μl is injected to the HPLC system equipped with a Polymer C18 column (2.0 x 75 mm). The mobile phase consists of 24% to 66% acetonitorile linear gradient, including 10 mM of ammonium phosphate, with a flow rate of 0.35 ml/min. The IC 5 o value is determined using the equation: wherein [I] means the concentration of the test compound. The most preferred compounds among the title compounds of the Examples described below showed 1C 50 values of less than 5 μM, preferably less than 1μm, and more preferably less than 500nM.
