Asymmetric N-(3,3-diphenylpropyl)aminoalkyl esters of 4-aryl-2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylic acids with antihypertensive activity
摘要:
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 H-3-nitrendipine in the calcium channel. Introduction of this bulky and lipophilic amine confers to the whole series an elevated level of antihypertensive activity and a long duration of action, a structure-dependent modulation of the activity being found only in the subset characterized by the presence of a branched propylene bridge between the ester and the amino groups. The presence of the amino group is essential for oral activity. Out of this series, compound 9u (Rec 15/2375-lercanidipine) was selected for clinical development and obtained marketing authorization as an antihypertensive in several countries.

Compounds of the formula ##STR1## in which R represents a carbocyclic or heterocyclic aryl radical, R.sub.1 represents lower alkyl, one of the groups R.sub.2 and R.sub.3 represents lower alkyl and the other represents lower alkyl, cyano or amino, X represents oxygen or the group --NH--, and Alk represents lower alkylene which separates the group X from the ring nitrogen atom by at least two carbon atoms, Y represents the group --CHOH-- or --(C.dbd.O)--, and Ar.sub.1 represents a monocyclic aryl or heteroaryl radical, Ar.sub.1 being other than unsubstituted phenyl if R.sub.1, R.sub.2 and R.sub.3 each represents lower alkyl, X represents oxygen, Alk represents straight-chain alkylene having from 2 to 4 carbon atoms, Y represents the group --(C.dbd.O)-- and R has the meaning given, and salts thereof have cardiovascular, especially coronary-dilatory and antihypertensive properties.
