antituberculosis activity against Mycobacterium tuberculosis H37Ra in vitro. Based on this activity, compound 4a showed the most potent inhibitory activity, with a minimum inhibitory concentration (MIC) value of 17 μM. In addition, six other synthesized compounds, 5a and 5c–5g, exhibited moderate activity, with MIC ranges between 60 μM to 140 μM. Compound 4a showed good bactericidal activity with a minimum
通过查尔酮衍生物与不同类型的氨基脲进行环缩合反应,共合成了十四种吡唑啉衍生物。这些化合物的特征在于IR,1D-NMR(1 H,13 C和通过极化转移无畸变增强-DEPT-135)和2D-NMR(COSY,HSQC和HMBC)以及质谱分析(HRMS)。测试了所合成的化合物在体外对结核分枝杆菌H37Ra的抗结核活性。基于该活性,化合物4a表现出最强的抑制活性,最小抑制浓度(MIC)值为17μM。此外,还有其他六种合成化合物5a和5c-5g表现出中等活性,MIC在60μM至140μM之间。化合物4a对结核分枝杆菌H37Ra表现出良好的杀菌活性,最小杀菌浓度(MBC)值为34μM。进行了化合物4a在α-固醇脱甲基酶上的分子对接研究,以了解和探索配体-受体的相互作用,并推测该化合物的潜在改进方法。
