In the current study, four new 2-alkyl-N-biphenyl fused imidazoles were synthesized and the pharmacological properties of these compounds as angiotensin II antagonists were studied. First, the potency of the synthesized compounds on guinea-pig ileum was evaluated and the vasopressor effect of the most potent compound 6a was compared with losartan on isolated perfused rat kidney. The antagonistic activity of compound 6a (sodium 2-propyl-5-carbomethoxy-1-[(biphenyl-4-yl)methyl]pyrrolo[3,2-d]imidazole-2'-carbo xylate) on angiotensin II receptors was greater than the other synthesized compounds and in isolated perfused rat kidney was similar to losartan.
