at position 4 was replaced by a 1‐methyl‐4,5‐dichloroimidazolyl substituent, were synthesized and evaluated as calcium‐channel antagonists using the high K+ concentration of guinea‐pig ileum longitudinal smooth muscle. The structure of all compounds was confirmed by IR, 1H‐NMR, and mass spectra. The calcium‐channel antagonist activity of compounds 10a–f demonstrated that compound 10b was the most active
合成了一组硝苯地平的二烷基和二芳基酯类似物,其中 4 位的邻硝基苯基被 1-甲基-4,5-二氯咪唑基取代,合成并评估为使用高 K + 浓度的钙通道拮抗剂豚鼠回肠纵向平滑肌。所有化合物的结构均经 IR、1H NMR 和质谱证实。化合物 10a-f 的钙通道拮抗剂活性表明,化合物 10b 的活性最高,而 10f 的活性最低。对于不对称二酯 12a-k,最活跃的化合物是乙基苯乙基衍生物。
