A series of [(2-aminoheterocycloethoxy)methyl]dihydropyridines were prepared as selective coronary vasodilators. Results showed that a wide variety of five- and six-membered heterocycles were acceptable at the 2-position of the dihydropyridine ring and in vitro potency and tissue selectivity was independent of the basicity of these heterocycles. The SAR indicated that activity was optimum when the
制备了一系列[(2-氨基杂环乙氧基)甲基]二氢吡啶类作为选择性冠状血管扩张剂。结果表明,在二氢吡啶环的2位上可以接受多种五元和六元杂环,并且体外效能和组织选择性与这些杂环的碱性无关。SAR表明,当最大的酯基置于3而不是5位置时,活性最佳。2-[[[2-[(3-氨基-1H-1,2,4-三唑-5-基)氨基]乙氧基]甲基] -4-(2,3-二氯苯基)-3-(乙氧基羰基)-5 -(甲氧羰基)-6-甲基-1,4-二氢吡啶(3b)(UK-52,831)表现为有效的(IC50 = 6.3 X 10(-9)M)和组织选择性钙通道阻滞剂,且作用持续时间麻醉的狗大于7小时。
