A series of asymmetric 4-aryl-1, 4-dihydropyridine-3, 5-dicarboxylates characterized by the presence of a 3, 3-diphenyl-propylamino moiety in one of the ester groups were synthesized. They exhibited remarkable antihypertensive activity in spontaneously hypertensive rats as well as affinity for the 1, 4-dihydropyridines binding site labelled by 3H- nitrendipine in the calcium channel. Introduction of this bulky and lipophilic amine confers ...
