‐(4)‐imidazolyl substituent, were synthesized and evaluated as calcium channel antagonists using the high K+ contraction of guinea pig ileal longitudinal smooth muscle. The results for the symmetrical ester series showed that increasing the length of the chain in C3‐ and C5‐ester substituents increased the activity and the most active compound was the diphenylethyl ester derivative, so it was more
硝苯地平的一系列二烷基、二环烷基和二芳基酯类似物,其中 4 位的邻硝基苯基被 4-(5)-氯-2-乙基-5-(4)-咪唑基取代,使用豚鼠回肠纵向平滑肌的高 K + 收缩合成并评估钙通道拮抗剂。对称酯系列的结果表明,增加C3-和C5-酯取代基中链的长度会增加活性,活性最强的化合物是二苯乙酯衍生物,因此比参考药物硝苯地平更具活性。在不对称二酯系列中,当 R1 为甲基或乙基时,增加 R 取代基的亲油性,增加活性。最活跃的化合物是甲基/苯乙基和乙基/苯乙基酯衍生物,
