4-oxadiazol-2-one derivatives were synthesized and tested for their in vitro antimycobacterial activity. Oxadiazolone derivatives showed an interesting antimycobacterial activity against the tested strain of Mycobacterium tuberculosis H(37)Rv, whereas the corresponding thione derivatives were devoid of activity. Molecular modeling investigations showed that the active compounds may interact at the active site of
合成了3H-1,3,4-恶二唑-2-硫酮和3H-1,3,4-恶二唑-2-酮衍生物并测试了其体外抗分枝杆菌活性。恶二唑酮衍生物对测试的结核分枝杆菌H(37)Rv菌株显示出有趣的抗分枝杆菌活性,而相应的硫酮衍生物则没有活性。分子模型研究表明,活性化合物可能在固醇生物合成途径中的分枝杆菌细胞色素P450依赖性固醇14α-脱甲基酶的活性位点相互作用,并且它们的结合自由能值与其MIC值一致。
