quinoline–aminopiperidine hybrid MTB DNA gyrase inhibitors with aiming more potency and less cardiotoxicity. We synthesized thirty six compounds using four step synthesis from 2-chloro benzoic acid. Among them compound 4-chloro-N-(4-((2-methylacridin-9-yl)amino)phenyl)benzenesulphonamide (6) was found to be more potent with MTB DNA gyrase super coiling IC50 of 5.21 ± 0.51 μM; MTB MIC of 6.59 μM and no zHERG cardiotoxicity
在这项研究中,我们从较早报道的喹啉-氨基哌啶杂化MTB DNA促旋酶抑制剂中设计了对苯二胺连接的a啶衍生物,其目的是提高药效和降低心脏毒性。我们使用2-氯苯甲酸四步合成法合成了36种化合物。其中化合物4-氯-N-(4-(((2-甲基rid啶-9-基)氨基)苯基)苯磺酰胺(6)用MTB DNA促旋酶超级卷曲IC 50为5.21±0.51μM更有效。对小鼠巨噬细胞系RAW 264.7的MTB MIC为6.59μM,在30μM时无zHERG心脏毒性,在50μM时无11.78%的抑制作用。
