  approximately three-fold more active than nifedipine as a calcium antagonist. A docking study with the DHP receptor model was performed to interpret the differences in calcium antagonist activities. The molecular docking study demonstrated that the lipophilicity of the substituted phenyl group at the 4-position of the DHP ring is an important factor that could increase the activity of the calcium antagonist

  1,4-二氢吡啶（DHP）是一类重要的钙拮抗剂。它通过L型电压依赖性钙通道抑制细胞外Ca + 2的流入。合成了两个系列的硝苯地平类似物并评估为钙拮抗剂。硝苯地平的邻硝基苯基环被邻或间氯苯基取代基取代。IC50值表明，某些化合物的活性类似于硝苯地平或比硝苯地平更具活性。在DHP环的3和5位上用适当体积的基团（如乙酯）取代，得到3h，其活性比硝苯地平作为钙拮抗剂高3倍。进行了与DHP受体模型的对接研究，以解释钙拮抗剂活性的差异。分子对接研究表明，DHP环4位上的取代苯基的亲脂性是一个重要因素，考虑到空间因素，它可以增加钙拮抗剂的活性。庞大的基团干扰了与Tyr1460的环到环疏水相互作用，并限制了增加DHP环3和5位上的酯烃链长度的效率，以此作为提高活性的一种方法。DHP环的4位上苯环上存在螯合取代基可确保与受体的牢固结合，从而确保闭通道构象的稳定。
