A novel series of human leukocyte elastase (HLE) inhibitors containing the beta-carbolinone ring system are reported. The design of these trifluoromethyl ketone-based inhibitors used a combination of structural information obtained from X-ray crystallography and molecular modeling investigations. The beta-carbolinone ring in these compounds serves as a highly efficient peptidiomimetic for the P2-P3
据报道,含有β-咔啉酮环系统的一系列新的人类白细胞弹性蛋白酶(HLE)抑制剂。这些基于三氟甲基酮的抑制剂的设计结合了从X射线晶体学和分子模型研究中获得的结构信息。这些化合物中的β-咔啉酮环可作为HLE肽基三氟甲基酮抑制剂的P2-P3区的高效拟肽模拟物。几种β-咔啉酮具有显着的体外效能,Ki值在纳摩尔范围内。使用水分子动力学模拟,已获得并讨论了通过HLE对这些抑制剂进行分子识别的现实模型。发现该系列化合物对HLE的选择性优于许多其他蛋白水解酶,
