Several heterocyclic analogues of the potent 1-[[4-(aminoalkoxy)phenyl]sulfonyl]indolizines were synthesized and evaluated for their antagonistic calcium activities in comparison with the 1-sulfonylindolizine SR 33557 and the usual calcium antagonist references verapamil, cis-(+)-diltiazem, and nifedipine. The bicyclic nine-membered rings were, in general, more potent than the bicyclic 10-membered
合成了有效的1-[[[4-(氨基烷氧基)苯基]磺酰基]吲哚嗪酮的几种杂环类似物,并与1-磺酰吲哚嗪SR 33557和通常的钙拮抗剂参考维拉帕米,顺式-(+ )-地尔硫卓和硝苯地平。通常,双环九元环比双环十元或五元环更有效。在双环九元环中,吲哚核似乎非常有利于支持钙拮抗活性。尤其是,化合物36对[3H]硝苯地平的抑制作用的IC50值等于0.072 nM,是已知的最有效的钙拮抗剂。已选择该化合物进行临床开发。
