bacteria by preventing the efflux of administered antibiotics. In this study, we optimized the chemical structure of a previously identified bacterial-selective MATE inhibitor 1 (EC50 > 30 µM) to improve its activity further. Compound 1 was divided into three fragments (aromatic part, linker part, and guanidine part), and each part was individually optimized. Compound 31 (EC50 = 1.8 µM), a novel pentaf
多药和毒素挤出 (MATE) 抑制剂通过阻止所施用抗生素的外流来提高耐药细菌的抗菌敏感性。在这项研究中,我们优化了先前鉴定的细菌选择性 MATE 抑制剂1 (EC 50 > 30 µM)的化学结构,以进一步提高其活性。化合物1被分为三个片段(芳香部分、接头部分和胍部分),并且每个部分都被单独优化。化合物31 (EC 50 = 1.8 µM) 是一种按照优化部分合成的新型含五氟硫基分子,与诺氟沙星共同给药时,其浓度低于传统抑制剂1 ,对表达 MATE 的菌株表现出抗菌活性。此外, 31在有效浓度下不具有细胞毒性。这表明化合物31可能是对抗细菌感染的有希望的候选者,特别是那些通过 MATE 表达对传统抗生素产生耐药性的细菌感染。
