  作为人中性粒细胞弹性蛋白酶抑制剂的 N-苯并吲哚衍生物的优化

  摘要：

  人类中性粒细胞弹性蛋白酶 (HNE) 是治疗肺部疾病的重要治疗靶点。以前，我们将新型N-苯甲酰基吲唑衍生物鉴定为有效、竞争性和假不可逆的 HNE 抑制剂。在这里，我们报告了这些抑制剂的进一步开发，与我们之前的先导相比，这些抑制剂具有更高的效力、蛋白酶选择性和稳定性。在吲唑的 5 位引入各种取代基产生了有效的抑制剂20f (IC 50 ∼10 nM)，而在 3 位的修饰产生了该系列中最有效的化合物，即 3-CN 衍生物5b (IC 50= 7纳米）；与其他丝氨酸蛋白酶相比，这两种衍生物对 HNE 均表现出良好的稳定性和特异性。选定的N-苯甲酰基吲唑与 HNE 结合域的分子对接表明抑制活性取决于配体-酶复合物的几何形状。事实上，配体形成 Michaelis 复合物的能力以及 Hys57、Asp102 和 Ser195 之间质子转移的有利条件都会影响活性。

  reflex in rats are described. Heteroaromatic rings such as pyrrole, thiophene, furan, pyridine, pyridazine, 1,2-benzisoxazole, indole, quinoline, and isoquinoline rings showed weak 5-HT3 receptor antagonistic activity. Within this series, use of the 1H-indazole ring as an aromatic moiety led to a substantial increase of the activity; the 1H-indazolylcarboxamides 54, 57, 97, and 102 showed potent 5-HT3
