A series of compounds has been synthesized and demonstrated to be antagonists of the angiotensin II (AII) receptor. These compounds are structurally related to the N-(benzamidobenzyl)imidazoles and extend the scope of this new class of nonpeptide AII antagonists. It has been found that the amide linkage (X = NHCO) in the N-(benzamidobenzyl)imidazoles can be replaced successfully by a variety of groups (X = single bond, O, S, CO, OCH2, CH = CH, NHCONH); linkers of 0-1 atoms in length are most effective. When administered intravenously to awake renal hypertensive rats, these compounds are potent antihypertensives.
