Novel therapies are required to treat chronic bacterial infections in cystic fibrosis (CF) sufferers. The most common pathogen responsible for these infections is Pseudomonas aeruginosa, which persists within the lungs of CF sufferers despite intensive antibiotic treatment. P. aeruginosa elastase (also known as LasB or pseudolysin) is a key virulence determinant that contributes to the pathogenesis
需要新的疗法来治疗囊性纤维化 (CF) 患者的慢性细菌感染。导致这些感染的最常见病原体是铜绿假单胞菌,尽管进行了强化抗生素治疗,但它仍然存在于 CF 患者的肺部。铜绿假单胞菌弹性蛋白酶(也称为 LasB 或假溶素)是导致CF 患者中铜绿假单胞菌感染的发病机制和持续存在的关键毒力决定因素。LasB 在假单胞菌毒力中的关键作用使其成为开发 CF 治疗辅助药物的良好靶点。在这里,我们讨论了通过虚拟筛选和计算机辅助药物设计 (CADD) 发现一系列新的 LasB 抑制剂及其优化化合物29和39 ( K i = 0.16 μM 和 0.12 μM,分别)。
