Human leukocyte elastase (HLE) has been proposed to be a primary mediator of pulmonary emphysema, and inhibitors of this enzyme should be effective in the treatment of emphysema and other pulmonary diseases. We have discovered a novel class of alicyclic and heterocyclic leaving groups which share one common structural feature, a cyclic beta-dicarbonyl. This design concept for leaving groups has not
已经提出人白细胞弹性蛋白酶(HLE)是肺气肿的主要介体,并且该酶的抑制剂在肺气肿和其他肺部疾病的治疗中应该是有效的。我们发现了一类新的脂环族和杂环离去基团,它们具有一个共同的结构特征,即环状β-二羰基。离开小组的这种设计概念以前没有被报道过。已经建立了结构-活性关系,并且该概念扩展到几种类型的脂环族和杂环β-二羰基系统。这项工作导致鉴定出强效(K * i为0.066 nM)和组织稳定(体外:血液t1 / 2 = 160分钟,肝脏t1 / 2> 240分钟)苯并异噻唑酮HLE抑制剂WIN 65936(13b)。
