  探索氮杂环支架用于开发强效人中性粒细胞弹性蛋白酶抑制剂

  摘要：

  人中性粒细胞弹性蛋白酶 (HNE) 是一种强效蛋白酶，在许多过程中发挥重要的生理作用，但也参与影响肺系统的各种病理。因此，能够抑制 HNE 蛋白水解活性的化合物可以代表有效的治疗方法。我们在此展示了一系列新的吡唑并吡啶和吡咯并吡啶衍生物作为 HNE 抑制剂，设计为我们先前合成的吲唑和吲哚的修饰，以评估氮位置变化和/或在支架中插入额外氮的影响生物活性和化学稳定性。我们获得了具有 IC 50的强效 HNE 抑制剂值在低纳摩尔范围（10-50 nM），一些化合物在磷酸盐缓冲液中表现出改善的化学稳定性（t 1/2 > 6 h）。分子模型研究表明，抑制活性严格依赖于 HNE Ser195 的 OH 基团与抑制剂的羰基碳之间形成的米氏复合物。此外，计算机ADMET 计算预测大多数新化合物将被最佳吸收、分布、代谢和排泄。因此，这些新的和有效的 HNE 抑制剂代表了未来治疗发展的新线索。
