concentration (MIC) of 0.42 μM. In this study, a series of substituted 2-acylamide-1,3-zole analogues were designed and synthesized, and their anti-Mtb activities were analyzed. In total, 17 compounds were found to be potent anti-Mtb agents, especially against the MDR- and XDR-MTB strains, with MIC values < 10 μM. These analogues can inhibit both drug-sensitive and drug-resistant Mtb. Four representative compounds
N-(5-氯苯并[d]恶唑-2-基)-4-甲基-1,2,3-噻二唑-5-羧酰胺氧酰胺已被确认为是Mtb H37Rv的有效抑制剂,其最低抑制浓度为( MIC)为0.42μM。在这项研究中,设计和合成了一系列取代的2-酰基酰胺-1,3-唑类似物,并分析了它们的抗Mtb活性。总共发现17种化合物是有效的抗Mtb剂,特别是针对MDR-和XDR-MTB菌株,MIC值<10μM。这些类似物可以抑制药物敏感性和耐药性Mtb。选择了四种代表性化合物进行进一步分析,结果表明化合物18具有可接受的安全性,并具有良好的药代动力学(PK)特性。此外,该化合物对革兰氏阳性菌显示出强效活性,MIC值为1.48–11.86μM。本文获得的数据表明,可以通过结构修饰开发有希望的抗Mtb候选药物,并且需要进一步的研究来探索其他化合物。
