agents, which are active against both the replicating form of Mtb (R-TB) and NRP-TB, are urgently needed. Herein, we report the synthesis and structure−activity relationships (SAR) of a series of 5-[(E)-2-arylethenyl]-3-isoxazolecarboxylic acid alkyl esters as potent anti-TB agents. Several compounds had submicromolar minimum inhibitory concentrations (MIC) against R-TB and were active against NRP-TB
结核病(TB)主要由结核分枝杆菌(Mtb)引起,是全世界传染病致死的主要原因之一。它与艾滋病毒并发感染,以及多重耐药结核病(MDR-TB)和广泛耐药结核病(XDR-TB)菌株的出现,进一步加剧了结核病的流行。尽管结核病具有全球影响力,但它仍被认为是一种被忽视的疾病,在过去的四十年中,尚未引入任何新的抗结核疗法。结核病的非复制性持续性形式(NRP-TB)决定了治疗时间,是治疗失败的推定原因。因此,新的抗结核病药物对两种Mtb复制形式均具有活性迫切需要(R-TB)和NRP-TB。在这里,我们报告了一系列有效的抗结核病药物5-[(E)-2-芳基乙烯基] -3-异恶唑羧酸烷基酯的合成和构效关系(SAR)。几种化合物具有对R-TB的亚微摩尔最低抑制浓度(MIC),并且在低微摩尔范围内具有抗NRP-TB的活性,因此代表了可能开发新的抗结核药物的诱人的先导化合物。
