In this study, we designed and synthesized a series of coumarin derivatives as antitubercular agents targeting the enoyl acyl carrier protein reductase (InhA) enzyme. Among the synthesized compounds, the tetrazole derivative 4c showed the most potent antitubercular effect with a minimum inhibitory concentration value (MIC) of 15 μg mL−1 against Mtb H37Rv and could also inhibit the growth of the mutant
在本研究中,我们设计并合成了一系列香豆素衍生物作为靶向烯酰酰基载体蛋白还原酶(InhA)的抗结核药物。在合成的化合物中,四唑衍生物4c对Mtb H37Rv表现出最强的抗结核作用,其最低抑制浓度(MIC)为15 μg mL -1 ,并且还可以抑制突变株(Δ katG )的生长。化合物4c能够穿透Mtb感染的人巨噬细胞并抑制结核杆菌的细胞内生长。此外,目标衍生物4c对InhA酶显示出有效的抑制作用,IC 50值为0.565 μM,优于参考InhA抑制剂三氯生。化合物4c在 InhA 活性位点内的分子对接揭示了 4-苯基香豆素环系统和四唑部分对于活性的重要性。最后,研究了4c的理化性质和药代动力学参数。
