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
合成了在3和/或5位上含有N,N,-二烷基氨基烷氧基羰基的新型2-氨基-1,4-二氢吡啶衍生物I,并在自发性高血压大鼠中评估了其降压作用。当叔氨基被引入1,4-二氢吡啶环的3-和/或5-酯侧链时,观察到抗高血压作用的持续时间显着延长。特别地,在3位含有环氨基的化合物比具有无环氨基的化合物显示出更高的效力。化学修饰研究表明,在3和5位的1,4-二氢吡啶的两个酯侧链可能以与抗高血压活性有关的不同方式起作用。
