Novel 2-Amino-1,4-dihydropyridine Calcium Antagonists. II. Synthesis and Antihypertensive Effects of 2-Amino-1,4-dihydropyridine Derivatives Having N,N-Dialkylaminoalkoxycarbonyl Groups at 3- and/or 5-Position.
potency than those with acyclic amino moieties. Chemical modification studies indicated that the two ester side-chains of 1,4-dihydropyridine at the 3- and 5-position might function in a different manner in relation to the antihypertensive activities. 3-(1-Benzhydrylazetidinited potent and long-lasting antihypertensive effects with gradual onset of action, and is a promising candidate as an antihypertensive
