vasodilating/beta-adrenergic blockingagent 2-[4-[3-(tert-butylamino)-2-hydroxypropoxy]phenyl]-4-(trifluoromethyl)imidazole (1) has been investigated. Introduction of selected substitutents onto the imidazole ring, in place of the trifluoromethyl group, has yielded highly cardioselective beta-adrenergic blockingagents such as 7, 17, and 18. The placement of alkyl or chloro groups onto the aryl ring of 1, as illustrated
Novel substituted imidazoles of the formula ##STR1## and methods for their preparation are disclosed. These imidazoles, and their salts, exhibit pharmacological activity which includes antihypertensive activity and .beta.-adrenergic blocking activity.

The aminohydroxypropoxy moiety has been incorporated into the dihydrolutidine class of vasodilators. In the spontaneously hypertensive rat, one of these, (S)-4-[2-methyl-4-[3-(tert-butylamino)-2-hydroxypropoxy]phenyl]-3,5-dicarboethoxy-1,4-dihydrolutidine (4c), exhibited antihypertensive activity on the order of the standard 4-[2-(trifluoromethyl)phenyl]-3,5-dicarboethoxy-1,4-dihydrolutidine (2a). This antihypertensive activity could not be explained in terms of a vasodilating effect, as determined in the dog. In this latter model, 2a decreased both mean arterial and hindlimb perfusion pressures.
