N-substituted N-(.alpha.-triazolyl-toluyl)pyrrole compounds for treatment of circulatory disorders

FIELD OF THE INVENTION
Non-peptidic N-substituted N-(.alpha.-triazolyltoluyl)pyrrol compounds are described for use in treatment of circulatory disorders such as hypertension and congestive heart failure. Of particular interest are angiotensin II antagonist compounds having an N-toluylpyrrole moiety attached to a nitrogen atom of 1H-1,2,4-triazole.
BACKGROUND OF THE INVENTION
The renin-angiotensin system is one of the hormonal mechanisms involved in regulation of pressure/volume homeostasis and in expression of hypertension. Activation of the renin-angiotensin cascade begins with renin secretion from the juxtaglomerular apparatus of the kidney and culminates in the formation of angiotensin II, the primary active species of this system. This octapeptide, angiotensin II, is a potent vasoconstrictor agent and also produces other physiological effects such as promoting aldosterone secretion, promoting sodium and fluid retention, inhibiting renin secretion, increasing sympathetic nervous system activity, increasing vasopressin secretion, causing positive cardiac inotropic effect and modulating other hormonal systems.
Previous studies have shown that antagonizing angiotensin II at its receptors is a viable approach to inhibit the renin-angiotensin system, given the pivotal role of this octapeptide which mediates the actions of the renin-angiotensin system through interaction with various tissue receptors. There are several known angiotensin II antagonists, most of which are peptidic in nature. Such peptidic compounds are of limited use due to their lack of oral bioavailability or their short duration of action. Also, commercially-available peptidic angiotensin II antagonists (e.g., Saralasin) have a significant residual agonist activity which further limit their therapeutic application.
Non-peptidic compounds with angiotensin II antagonist properties are known. For example, the sodium salt of 2-n-butyl-4-chloro-1-(2-chlorobenzyl)imidazole-5-acetic acid has specific competitive angiotensin II antagonist activity as shown in a series of binding experiments, functional assays and in vivo tests [P. C. Wong et al, J. Pharmacol. Exp. Ther., 247 (1), 1-7 (1988)]. Also, the sodium salt of 2-butyl-4-chloro-1-(2-nitrobenzyl)imidazole-5-acetic acid has specific competitive angiotensin II antagonist activity as shown in a series of binding experiments, functional assays and in vivo tests [A. T. Chiu et al, European J. Pharmacol., 157, 13-21 (1988)]. A family of 1-benzylimidazole-5-acetate derivatives has been shown to have competitive angiotensin II antagonist properties [A. T. Chiu et al, J. Pharmacol. Exp. Ther., 250 (3), 867-874 (1989)]. Blankey et al U.S. Pat. No. 4,816,463 describes a family of 4,5,6,7-tetrahydro-1H-imidazo (4,5-c) -tetrahydro-pyridine derivatives useful as antihypertensives, some of which are reported to antagonize the binding of labelled angiotensin II to rat adrenal receptor preparation and thus cause a significant decrease in mean arterial blood pressure in conscious hypertensive rats. EP No. 253,310, published 20 Jan. 1988, describes a series of aralkyl imidazole compounds, including in particular a family of biphenylmethyl substituted imidazoles, as antagonists to the angiotensin II receptor. EP No. 323,841 published 12 July 1989 describes four classes of angiotensin II antagonists, namely, biphenylmethylpyrroles, biphenylmethylpyrazoles, biphenylmethyl-1,2,3-triazoles and biphenylmethyl 4-substituted-4H-1,2,4-triazoles, including the compound 3,5-dibutyl-4-[(2'-carboxybiphenyl-4-yl)methyl]-4H-1,2,4-triazole. Carini et al U.S. Pat. No. 4,880,804 describes a family of biphenylmethylbenzimidazole compounds as angiotensin II receptor blockers for use in treatment of hypertension and congestive heart failure.
There are pyrrol-containing compounds known for pharmacological purposes. For example, U.S. Pat. No. 4,156,734 describes N-toluyl-substituted pyrrole-2-carboxylic acid compounds for use as antihypertensive agent. A family of 1-[p-methyl-.alpha.-[4-(1H-pyrrol-1-yl)phenyl]benzyl] azole compounds is described having antibacterial and antifungal properties, including the specific compound 1-[(4-methylphenyl)[4-(1H-pyrrol-1-yl)phenyl]methyl]-1H-1,2,4-triazole [S. Massa et al, Arch. Pharm., 322 (6), 369-73 (1989)].

Compounds of Formula I would be useful in treating a variety of circulatory disorders, including cardiovascular disorders, such as hypertension, congestive heart failure and arteriosclerosis, and to treat other disorders such as glaucoma. These compounds would also be useful as adjunctive therapies. For example, compounds of Formula I may be used in combination with other drugs, such as a diuretic, to treat hypertension. Also, compounds of Formula I could be used in conjunction with certain surgical procedures. For example, these compounds could be used to prevent post-angioplasty re-stenosis. Compounds of Formula I are therapeutically effective in treatment of cardiovascular disorders by acting as antagonists to, or blockers of, the angiotensin II (AII) receptor. Compounds of Formula I would be therapeutically effective in treatment of the above-mentioned circulatory and cardiovascular disorders or would be precursors to, or prodrugs of, therapeutically-effective compounds.
The phrase "acidic group selected to contain at least one acidic hydrogen atom", as used to define the --Y.sub.n A moiety, is intended to embrace chemical groups which, when attached to any of the R.sup.3 through R.sup.10 positions of Formula I, confers acidic character to the compound of Formula I. "Acidic character" means proton-donor capability, that is, the capacity of the compound of Formula I to be a proton donor in the presence of a proton-receiving substance such as water. Typically, the acidic group should be selected to have proton-donor capability such that the product compound of Formula I has a pK.sub.a in a range from about one to about twelve. More typically, the Formula I compound would have a pK.sub.a in a range from about two to about seven. An example of an acidic group containing at least one acidic hydrogen atom is carboxyl group (--COOH). Where n is zero and A is --COOH, in the --Y.sub.n A moiety, such carboxyl group would be attached directly to one of the R.sup.3 through R.sup.10 positions. The Formula I compound may have one --Y.sub.n A moiety attached at one of the R.sup.3 through R.sup.10 positions, or may have a plurality of such --Y.sub.n A moieties attached at more than one of the R.sup.3 through R.sup.10 positions, up to a maximum of eight such --Y.sub.n A moieties. There are many examples of acidic groups other than carboxyl group, selectable to contain at least one acidic hydrogen atom. Such other acidic groups may be collectively referred to as "bioisosteres of carboxylic acid" or referred to as "acidic bioisosteres". Specific examples of such acidic bioisosteres are described hereinafter. Compounds of Formula I having the --Y.sub.n A moiety attached at one of positions R.sup.5, R.sup.6, R.sup.7, and R.sup.8 would be expected to have preferred properties, while attachment at R.sup.5 or R.sup.8 would be more preferred.

The term "hydrido" denotes a single hydrogen atom (H). This hydrido group may be attached, for example, to an oxygen atom to form a hydroxyl group; or, as another example, two hydrido groups may be attached to a carbon atom to form a --CH.sub.2 -- group. Where the term "alkyl" is used, either alone or within other terms such as "haloalkyl" and "hydroxyalkyl", the term "alkyl" embraces linear or branched radicals having one to about twenty carbon atoms or, preferably, one to about twelve carbon atoms. More preferred alkyl radicals are "lower alkyl" radicals having one to about ten carbon atoms. Most preferred are lower alkyl radicals having one to about five carbon atoms. The term "cycloalkyl" embraces cyclic radicals having three to about ten ring carbon atoms, preferably three to about six carbon atoms, such as cyclopropyl, cyclobutyl, cyclopentyl and cyclohexyl. The term "haloalkyl" embraces radicals wherein any one or more of the alkyl carbon atoms is substituted with one or more halo groups, preferably selected from bromo, chloro and fluoro. Specifically embraced by the term "haloalkyl" are monohaloalkyl, dihaloalkyl and polyhaloalkyl groups. A monohaloalkyl group, for example, may have either a bromo, a chloro, or a fluoro atom within the group. Dihaloalkyl and polyhaloalkyl groups may be substituted with two or more of the same halo groups, or may have a combination of different halo groups. A dihaloalkyl group, for example, may have two fluoro atoms, such as difluoromethyl and difluorobutyl groups, or two chloro atoms, such as a dichloromethyl group, or one fluoro atom and one chloro atom, such as a fluoro-chloromethyl group. Examples of a polyhaloalkyl are trifluoromethyl, 1,1-difluoroethyl, 2,2,2-trifluoroethyl, perfluoroethyl and 2,2,3,3-tetrafluoropropyl groups. The term "difluoroalkyl" embraces alkyl groups having two fluoro atoms substituted on any one or two of the alkyl group carbon atoms. The terms "alkylol" and "hydroxyalkyl" embrace linear or branched alkyl groups having one to about ten carbon atoms any one of which may be substituted with one or more hydroxyl groups. The term "alkenyl" embraces linear or branched radicals having two to about twenty carbon atoms, preferably three to about ten carbon atoms, and containing at least one carbon-carbon double bond, which carbon-carbon double bond may have either cis or trans geometry within the alkenyl moiety. The term "alkynyl" embraces linear or branched radicals having two to about twenty carbon atoms, preferably two to about ten carbon atoms, and containing at least one carbon-carbon triple bond. The term "cycloalkenyl" embraces cyclic radicals having three to about ten ring carbon atoms including one or more double bonds involving adjacent ring carbons. The terms "alkoxy" and "alkoxyalkyl" embrace linear or branched oxy-containing radicals each having alkyl portions of one to about ten carbon atoms, such as methoxy group. The term "alkoxyalkyl" also embraces alkyl radicals having two or more alkoxy groups attached to the alkyl radical, that is, to form monoalkoxyalkyl and dialkoxyalkyl groups. The "alkoxy" or "alkoxyalkyl" radicals may be further substituted with one or more halo atoms, such as fluoro, chloro or bromo, to provide haloalkoxy or haloalkoxyalkyl groups. The term "alkylthio" embraces radicals containing a linear or branched alkyl group, of one to about ten carbon atoms attached to a divalent sulfur atom, such as a methythio group. Preferred aryl groups are those consisting of one, two, or three benzene rings. The term "aryl" embraces aromatic radicals such as phenyl, naphthyl and biphenyl. The term "aralkyl" embraces aryl-substituted alkyl radicals such as benzyl, diphenylmethyl, triphenylmethyl, phenylethyl, phenylbutyl and diphenylethyl. The terms "benzyl" and "phenylmethyl" are interchangeable. The terms "aryloxy" and "arylthio" denote radical respectively, aryl groups having an oxygen or sulfur atom through which the radical is attached to a nucleus, examples of which are phenoxy and phenylthio. The terms "sulfinyl" and "sulfonyl", whether used alone or linked to other terms, denotes respectively divalent radicals SO and SO.sub.2. The term "aralkoxy", alone or within another term, embraces an aryl group attached to an alkoxy group to form, for example, benzyloxy. The term "acyl" whether used alone, or within a term such as acyloxy, denotes a radical provided by the residue after removal of hydroxyl from an organic acid, examples of such radical being acetyl and benzoyl. "Lower alkanoyl" is an example of a more prefered sub-class of acyl. The term "amido" denotes a radical consisting of nitrogen atom attached to a carbonyl group, which radical may be further substituted in the manner described herein. The amido radical can be attached to the nucleus of a compound of the invention through the carbonyl moiety or through the nitrogen atom of the amido radical. The term "alkenylalkyl" denotes a radical having a double-bond unsaturation site between two carbons, and which radical may consist of only two carbons or may be further substituted with alkyl groups which may optionally contain additional double-bond unsaturation. The term "heteroaryl" embraces aromatic ring systems containing one or two hetero atoms selected from oxygen, nitrogen and sulfur in a ring system having five or six ring members, examples of which are thienyl, furanyl, pyridinyl, thiazolyl, pyrimidyl and isoxazolyl. Such heteroaryl may be attached as a substituent through a carbon atom of the heteroaryl ring system, or may be attached through a carbon atom of a moiety substituted on a heteroaryl ring-member carbon atom, for example, through the methylene substituent of imidazolemethyl moiety. Also, such heteroaryl may be attached through a ring nitrogen atom as long as aromaticity of the heteroaryl moiety is preserved after attachment. For any of the foregoing defined radicals, preferred radicals are those containing from one to about ten carbon atoms.
Specific examples of alkyl groups are methyl, ethyl, n-propyl, isopropyl, n-butyl, sec-butyl, isobutyl, tert-butyl, n-pentyl, isopentyl, methylbutyl, dimethylbutyl and neopentyl. Typical alkenyl and alkynyl groups may have one unsaturated bond, such as an allyl group, or may have a plurality of unsaturated bonds, with such plurality of bonds either adjacent, such as allene-type structures, or in conjugation, or separated by several saturated carbons.
For the R.sup.1 and R.sup.2 substituents which are each attached to a nitrogen atom of the triazole ring, it is preferred that certain selections of radicals for R.sup.1 and R.sup.2 be avoided. Radicals which should preferably be avoided are alkyl, alkenyl and alkynyl moieties having a halo, hydroxy, alkoxy or double bond or triple bond attached to the alpha carbon of the moiety, that is, the carbon attached to a nitrogen atom of the triazole ring.
Compounds of Formula I have been found to inhibit the action of angiotensin II in mammals. Angiotensin II is a potent vasoconstrictor and participates in the formation of aldosterone which regulates sodium and water balance in mammals. Thus, compounds of Formula I are therapeutically useful in methods for treating hypertension by administering to a hypertensive patient a therapeutically-effective amount of a compound of Formula I. The phrase "hypertensive patient" means, in this context, a mammalian subject suffering from or afflicted by the effects of hypertension or susceptible to a hypertensive condition if not treated to prevent or control such hypertension.
Also included in the family of compounds of Formula I are isomeric forms including diastereoisomers, regioisomers and the pharmaceutically-acceptable salts thereof. The term "pharmaceutically-acceptable salts" embraces salts commonly used to form alkali metal salts and to form addition salts of free acids or free bases. The nature of the salt is not critical, provided that it is pharmaceutically-acceptable. Suitable pharmaceutically-acceptable acid addition salts of compounds of Formula I may be prepared from an inorganic acid or from an organic acid. Examples of such inorganic acids are hydrochloric, hydrobromic, hydroiodic, nitric, carbonic, sulfuric and phosphoric acid. Appropriate organic acids may be selected from aliphatic, cycloaliphatic, aromatic, araliphatic, heterocyclic, carboxylic and sulfonic classes of organic acids, example of which are formic, acetic, propionic, succinic, glycolic, gluconic, lactic, malic, tartaric, citric, ascorbic, glucuronic, maleic, fumaric, pyruvic, aspartic, glutamic, benzoic, anthranilic, p-hydroxybenzoic, salicyclic, phenylacetic, mandelic, embonic (pamoic), methansulfonic, ethanesulfonic, 2-hydroxyethanesulfonic, pantothenic, benzenesulfonic, toluenesulfonic, sulfanilic, mesylic, cyclohexylaminosulfonic, stearic, algenic, .beta.-hydroxybutyric, malonic, galactaric and galacturonic acid.

General Synthesis of the N-.alpha.-bromo-4-toluyl-pyrroles
Scheme 1 describes a general synthetic pathway to N-4-toluyl-pyrrole derivatives. Treatment of an appropriately substituted 4-amino toluidine 1 with 2,5-diethoxytetrahydrofurane in the presence of a high-boiling protic solvent, gives N-4-toluylpyrroles 2. The reaction is best performed with glacial acetic acid as the solvent and preferably at temperatures between 50.degree. C. and the reflux temperature of the solvent as previously described in the literature [H. Gross, Chem. Ber., 93, 65, (1960); N. Elmin and N. Clauson-Kaas, 6,867, (1952)]. Formulation of the N-4-toluyl-pyrrole is carried out according to the Vilsmeier-Haaels reaction [W. J. Jackson et al., J. Am. Chem. Soc., 103, 533, (1981)]. The reaction is performed with phosphorous oxychloride and dimethylformamide with DMF acting as both the reagent and the solvent. The temperature of the reaction may vary between 0.degree. C. and reflux temperature of the DMF (110-120.degree. C.). The compounds were generally purified by chromatography on a silica gel column and subsequently recrystallized from a suitable solvent or distilled under reduced pressure. The N-(4-toluyl)-2-formylpyrrole 2 derivatives is then transformed into the desired oxime 3 by treatment with hydroxylamine hydrochloride preferably in a protic solvent such as an lower alcohol in the presence of a base such as hydroxide, carbonate salt of an alkali, trialkylamine, or sodiumhydride and preferably at temperatures between room temperature and 100.degree. C. The oximes 3 isolated by filtration, furnish the 1-(4-toluyl)-2-cyano-pyrroles when treated with a dehydration agent. Heating a suspension of the oxime 3 in a carboxyclic acid anhydride used as the solvent and the dehydrating agent, at a temperature between 50.degree. C. and 150.degree. C. for a period of time ranging between 1 and 12 hours provides the desired nitrile derivative 4. ##STR35## Conditions:
a.2,5-dimethoxytetrahydrofurane; acetic acid reflux 2 h.
b.DMF, POCl.sub.3.
c.hydroxylamine, methanol; acetic anhydride.
d.N-bromosuccinimide, CCl.sub.4, AIBN.
The cyano derivative a is reacted by a 1,3-dipolar cycloaddition with trialkyltin azide to produce the corresponding tetrazole 5 as described by K. Sisido et al [J. Organometal. Chem., 33, 337-46 (1971)] (Scheme 2). The reaction is advantageously performed with an excess of the trialkyltin azide in refluxing toluene or dimethylformamide as solvent. The N-(trimethylstannyl)tetrazole 5 can be converted to the free tetrazole by bubbling anydrous hydrogen chloride in an ethereal or alcoholic solution, or by treatment with aqueous sodium hydroxide. The unprotected tetrazole intermediate 6 is reacted with an aralkylhalide, such as trityl chloride, which will provide a removable protecting group for the tetrazole. This reaction is best performed with trityl chloride in an inert solvent such as dichloromethane in the presence of at least one equivalent of a non-nucleophilic base such as pyridine or a trialkylamine. The bromination of 7 to give the benzyl bromide 8 is performed with N-bromosuccinimide in the presence of AIBN or dibenzoylperoxide in an inert solvent such as carbon tetrachloride at a temperature from 40.degree. C. to reflux of the solvent used. In most cases, it is advantageous to convert the cyano derivative into the corresponding .alpha.-bromotoluyl-2-cyano-pyrrole 9. The bromination is performed according to the procedures described above for the conversion of 7 to 8 (Scheme 3). ##STR36##
In some cases, it is advantageous to introduce substituants R.sup.5 -R.sup.7 on 9. For example, Scheme 4 describes the use of chlorosuccinimide to chlorinate the pyrrole ring to give the dichloro adduct 10. ##STR37##
Preparation of the Triazoles
Synthetic Scheme 5 shows the preparation of 1H-1,2,4-triazoles 11 from ethyl iminoesters 12 and the corresponding hydrazide 13 via the general procedure outlined by H. Paul, G. Hilgetog and G. Jahnchen, Chem. Ber., 101, 2033 (1968). The free iminoesters 12 can be prepared from the corresponding iminoester hydrochlorides 14, which in turn can be prepared from the corresponding nitrile 15; the procedures for the preparation of 12 and 14 from 15 are outlined by P. Reynaud and R. D. Moreau, Bull. Soc. Chim. France, 2997 (1964). The hydrazides 13 can be either purchased or prepared from the corresponding methyl esters 16 and hydrazine. ##STR38##
Alkylation of the Triazoles
The conversion of triazole compounds to compound of Formula I is carried out by alkylation of the anion of a triazole 11 with a pyrrole derivative of type 8-10 as the alkylating agent. The leaving group in 8-10 can be an halogen (with the exception of fluorine) group, a tosylate or a mesylate; preferably a bromine atom is the leaving group. The reaction solvent can be methylene chloride, tetrahydrofurane, dioxane, water, dimethylformamide or dimethylsulfoxide and the presence of an acid binding agent such as sodium, potassium or cesium carbonate, sodium hydroxide, triethylamine, potassium t-butoxide, sodium hydride is required. The most appropriate base is sodium hydride. The reaction is best performed at a temperature between 0.degree. C. and 120.degree. C. ##STR39##
The anion of 11 when reacted with an alkylating agent 8 gives a mixture of regioisomers 17 and 18. The isomer mixture may be converted to mixtures of the corresponding tetrazoles 19 and 20 by treatment with the appropriate reagent. Or, the isomers 17 and 18 may be separated by chromatographic methods, and each isomer may be reacted with the appropriate reagent to provide the tetrazole-substituted end product. A suitable method as described by Greene in "Protective Group in Organic Synthesis" Wiley-Interscience, 1980, can be used to remove the triphenylmethyl group. Such methods include hydrogenation in the presence of a catalyst such as palladium or platinum and hydrolysis under basic or acidic conditions. The reaction is performed in a solvent or a mixture of solvents such as acetone, water, glacial acetic acid, or a lower alcohol at temperatures preferably between 0.degree. C. and 100.degree. C.
Another route to compounds of Formula I involves the alkylation with a nitrile derivative of type 9 or 10 of a triazole derivative (Scheme 7). The leaving group in 9 or 10 can be halogen (with the exception of fluorine), tosylate, or mesylate with a bromine being the preferred leaving group. The reaction is best conducted in methylene chloride, acetonitrile, tetrahydrofurane, dioxane, water, dimethylformamide or dimethylsulfoxide in the presence of an acid binding agent such as sodium, potassium or cesium carbonate, sodium hydroxide, triethylamine, potassium t-butoxide or sodium hydride at a temperature between 0.degree. C. and 120.degree. C.
Synthetic Scheme 7 shows the coupling reaction of a 1H-1,2,4-triazole 11 with the appropriate alkylating reagent 9. In the first step, 11 is treated with a base, such as sodium hydride, to generate the corresponding anion. The anion is reacted with the alkylating agent 9 to give a mixture of regioisomers 21 and22. The isomer mixture may be converted to mixtures of the corresponding tetrazoles 23 and 24by treatment with the appropriate reagent. Or, the isomers 21 and 22may be separated by chromatographic methods, and each isomer may be reacted with the appropriate reagent to provide the acid- or tetrazole-substituted end product. The alkylated cyano derivatives (21-22) can be transformed into a compound of Formula I by converting the cyanide group into a tetrazole. Trialkyltin azide (K. Sisido, J. Organometal Chem., 33, 337-66, 1971) is preferably used in a high boiling temperature solvent (Scheme 7). The N(trimethylstannyl) intermediate is converted to the free tetrazole by the action of dilute acid. The tetrazole can also be generated by heating the cyanide derivative 19 with sodium azide and amonium chloride in dimethylformamide at a temperature close to reflux temperature. ##STR40##

The reaction mixture was poured on crushed ice and the pH adjusted to 4 with concentrated hydrochloric acid. A buff colored precipitate was collected which was dried and identified as the acid: mp 182.degree.-4.degree. C.
Step e. Preparation of 1-(4-methyl)phenyl-1H-pyrrole-2-carboxylic acid, methyl ester.
The acid from Step d was dissolved in 100 mL of thionyl chloride. The resulting dark red solution was stirred at 25.degree. C. for 4 h and then concentrated to an oil. Methanol (100 mL) was slowly added and the reaction mixture stirred for 16 h at 25.degree. C. The solution was reconcentrated to an oil and purified by filtration through a pad of silica gel (eluant: methylene chloride). Trituration with hexane gave 22 g of ester: mp 74.2.degree.-74.7.degree. C.; NMR (CDCl.sub.3) .delta. 7.2 (m, 4H), 7.05 (d, J=7 Hz, 1H), 6.9 (d, J=7 Hz, 1H), 6.25 (t, J=7 Hz, 1H), 3.7 (s, 3H), 2.4 (s, 3H).

BIOLOGICAL EVALUATION
Assay A: Angiotensin II Binding Activity
Compounds of the invention were tested for ability to bind to the smooth muscle angiotensin II receptor using a rat uterine membrane preparation. Angiotensin II (AII) was purchased from Peninsula Labs. .sup.125 I-angiotensin II (specific activity of 2200 Ci/mmol) was purchased from Du Pont-New England Nuclear. Other chemicals were obtained from Sigma Chemical Co. This assay was carried out according to the method of Douglas et al [Endocrinology, 106, 120-124 (1980)]. Rat uterine membranes were prepared from fresh tissue. All procedures were carried out at 4.degree. C. Uteri were stripped of fat and homogenized in phosphate-buffered saline at pH 7.4 containing 5 mM EDTA. The homogenate was centrifuged at 1500.times.g for 20 min., and the supernatant was recentrifuged at 100,000.times.g for 60 min. The pellet was resuspended in buffer consisting of 2 mM EDTA and 50 mM Tris-HCl (pH 7.5) to a final protein concentration of 4 mg/ml. Assay tubes were charged with 0.25 ml of a solution containing 5 mM MgCl.sub.2, 2 mM EDTA, 0.5% bovine serum albumin, 50 mM Tris-HCl, pH 7.5 and .sup.125 I-AII (approximately 10.sup.5 cpm) in the absence or in the presence of unlabellea ligand. The reaction was initiated by the addition of membrane protein and the mixture was incubated at 25.degree. C. for 60 min. The incubation was terminated with ice-cold 50 mM Tris-HCl (pH 7.5) and the mixture was filtered to separate membrane-bound labelled peptide from the free ligand. The incubation tube and filter were washed with ice-cold buffer. Filters were assayed for radioactivity in a Micromedic gamma counter. Nonspecific binding was defined as binding in the presence of 10.mu.M of unlabelled AII. Specific binding was calculated as total binding minus nonspecific binding. The receptor binding affinity of an AII antagonist compound was indicated by the concentration (IC.sub.50) of the tested AII antagonist which gives 50% displacement of the total specifically bound .sup.125 -AII from the high affinity AII receptor. Binding data were analyzed by a nonlinear least-squares curve fitting program. Results are reported in Table I.
Assay B: In Vitro Vascular Smooth Muscle-Response for AII
The compounds of the invention were tested for antagonist activity in rabbit aortic rings. Male New Zealand white rabbits (2-2.5 kg) were sacrificed using an overdose of pentobarbital and exsanguinated via the carotid arteries. The thoracic aorta was removed, cleaned of adherent fat and connective tissue and then cut into 3-mm ring segments. The endothelium was removed from the rings by gently sliding a rolled-up piece of filter paper into the vessel lumen. The rings were then mounted in a water-jacketed tissue bath, maintained at 37.degree. C. between moveable and fixed ends of a stainless steel wire with the moveable end attached to an FT03 Grass transducer coupled to a Model 7D Grass Polygraph for recording isometric force responses. The bath was filled with 20 ml of oxygenated (95% oxygen/5% carbon dioxide) Krebs solution of the following composition (mM): 130 NaCl, 15 NaHCO.sub.3, 15 KCl, 1.2 NaH.sub.2 PO.sub.4, 1.2 MgSO.sub.4, 2.5 CaCl.sub.2, and 11.4 glucose. The preparations were equilibrated for one hour before approximately one gram of passive tension was placed on the rings. Angiotensin II concentration-response curves were then recorded (3.times.10.sup.-10 to 1.times.10.sup.-5 M). Each concentration of AII was allowed to elicit its maximal contraction, and then AII was washed out repeatedly for 30 minutes before rechallenging with a higher concentration of AII. Aorta rings were exposed to the test antagonist at 10.sup.-5 M for 5 minutes before challenging with AII. Adjacent segments of the same aorta ring were used for all concentration-response curves in the presence or absence of the test antagonist. The effectiveness of the test compound was expressed in terms of pA.sub.2 values and were calculated according to H. O. Schild [Br. J. Pharmacol. Chemother., 2, 189-206 (1947)]. The pA.sub.2 value is the concentration of the antagonist which increases the EC.sub.50 value for AII by a factor of 2. Each test antagonist was evaluated in aorta rings from two rabbits. Results are reported in Table I.
Assay C: In Vivo Intraduodenal Pressor Assay Response for AII Antagonists
Male Sprague-Dawley rats weighing 225-300 grams were anesthetized with Inactin (100 mg/kg, i.p.) and catheters were implanted into the trachea, femoral artery, femoral vein and duodenum. Arterial pressure was recorded from the femoral artery catheter on a Gould chart recorder (Gould, Cleveland, Ohio). The femoral vein catheter was used for injections of angiotensin II, mecamylamine and atropine. The tracheal catheter allows for airway patency, and the duodenal catheter was used for intraduodenal (i.d.) administration of test compounds. After surgery, the rats were allowed to equilibrate for 30 minutes. Mecamylamine (3 mg/kg, 0.3 ml/kg) and atropine (400 ug/kg, 0.3 ml/kg) were then given i.v. to produce ganglion blockade. These compounds were administered every 90 minutes throughout the test procedure. Angiotensin II was given in bolus doses i.v. (30 ng/kg in saline with 0.5% bovine serum albumin, 0.1 ml/kg) every 10 minutes three times or until the increase in arterial pressure produced was within 3 mmHg for two consecutive AII injections. The last two AII injections were averaged and were taken as the control AII pressor response. Ten minutes after the final control AII injection, the Lest compound (dissolved in sodium bicarbonate) was administered i.d. at a dose of 30 mg/kg in a volume of 0.2 ml. Angiotensin II injections were then given 5, 10, 20, 30, 45, 60, 75, 90, and 120 minutes after administration of the test compound and response of arterial pressure was monitored. The response to AII was calculated as percent of the control response and then the percent inhibition is calculated as 100 minus the percent control response. Duration of action of a test compound was defined as the time from peak percent inhibition to 50% of peak. One compound at one dose was tested in each rat. Each test compound was tested in two rats and the values for the two rats were averaged. Results are reported in Table I.
