inhibitors based on a pyrazolo[1,5-a]-1,3,5-triazine scaffold, that the serine protease DegS and the cell envelope stress-response pathway σE represent a target for generating antibiotics with a novel mode of action. Moreover, DegS inhibition is synergistic with well-established membrane-perturbing antibiotics, thereby opening promising avenues for rational antibiotic drug design.
尽管有数百种抗生素药物可供使用,但传染病仍然是最臭名昭著的健康问题之一。此外,耐多药病原体的传播与新型抗生素的开发之间的差异说明了重要的未满足医疗需求,这只能通过确定新的靶标来解决。在本文中,我们通过开发第一种基于
吡唑并[1,5-a] -
1,3,5-三嗪支架的体内活性DegS
抑制剂,证实
丝氨酸蛋白酶DegS和细胞包膜应激反应途径σE代表产生具有新颖作用方式的抗生素的靶标。此外,DegS抑制与成熟的膜干扰抗生素协同作用,从而为合理的抗生素药物设计开辟了有希望的途径。
