Studies on nonpeptide angiotensin II receptor antagonists. I. Synthesis and biological evaluation of pyrazolo [1,5-b][1,2,4]triazole derivatives with alkyl substituents

Alkyl-substituted pyrazolo[1,5-b][1,2,4]triazole derivatives were synthesized and evaluated for activity as angiotensin II receptor antagonists. Molecules with the (methylbiphenylyl)tetrazole moiety at N-5 were the preferred compounds. Ethyl substitutions
