ANGIOTENSIN II ANTAGONIST 1-BIPHENYLMETHYLIMIDAZOLE COMPOUNDS AND THEIR THERAPEUTIC USE

Compounds of the following formula (I) or the formula (I) p : STR1 wherein R 1 is alkyl or alkenyl; R 2 and R 3 are hydrogen, alkyl, alkenyl, cycloalkyl, aralkyl, aryl, or aryl fused to cycloalkyl; R 4 is hydrogen, alkyl, alkanoyl, alkenoyl, arylcarbonyl, alkoxycarbonyl, tetrahydropyranyl, tetrahydrothiopyranyl, tetrahydrothienyl, tetrahydrofuryl, a group of formula--SiR a R b R c, in which R a, R b and R c are alkyl or aryl, alkoxymethyl, (alkoxyalkoxy)methyl, haloalkoxymethyl, aralkyl, aryl or alkanoyloxymethoxycarbonyl; R 5 is carboxy or--CONR 8 R 9, wherein R 8 and R 9 hydrogens or alkyl, or R 8 and R 9 together form alkylene; R 6 is hydrogen, alkyl, alkoxy or halogen; R. sup.7 is carboxy or tetrazol-5-yl; R p. sup.1 is hydrogen, alkyl, cycloalkyl or alkanoyl; R p 2 is a single bond, alkylene or alkylidene; R p 3 and R p 4 are each hydrogen or alkyl; R. sub.p 6 is carboxy or tetrazol-5-yl; and X p is oxygen or sulfur; and pharmaceutically acceptable salts and esters thereof. The compounds are AII receptor antagonists and thus have hypotensive activity and can be used for the treatment and prophylaxis of hypertension. The compounds may be prepared by reacting a biphenylmethyl compound with an imidazole compound.
