challenge, particularly because of the emergence of drug resistant mycobacterial strains, highlighting the need of development of new drugs. We report twenty-four new compounds that are designed and synthesized by converging thiolactone and quinoline scaffolds as potential antitubercular entities. Bacterial assay demonstrated one of the conjugates, 4f to be a highly potent molecule with minimum inhibitory
结核病感染构成了严峻的挑战,特别是由于耐药分枝杆菌菌株的出现,凸显了开发新药的必要性。我们报告了二十四种新化合物,这些化合物是通过将硫内酯和喹啉支架聚合而设计和合成的,作为潜在的抗结核实体。细菌测定表明,其中一种缀合物 4f 是一种高效分子,最低抑菌浓度 (MIC) 值为 0.5 μg/mL,与一线药物相当。值得注意的是,缀合物 4f 对利福平和多重耐药分枝杆菌菌株表现出相似的效力,同时对正常细胞表现出很小的毒性。体内研究证明了该缀合物进一步开发的巨大潜力。最后,对四个不同靶点进行了分子对接研究,以阐明可能的作用机制。
