cyclohexane-1,3-dione based structures 5 and 6 as hits. The selected hit molecules were used for further synthesis and a library of 37 compounds under four families was synthesized for lead generation. Evaluation of the library against M. tuberculosis lead to the identification of three lead antituberculosis agents (37, 39 and 41). The most potential compound, 2-(((2-hydroxyphenyl)amino)methylene)-5,5-dimethylcyclohexane-1
本研究利用基于全细胞的表型筛选数千种针对结核分枝杆菌H37Rv(M.tb.)的小分子,并将基于环己烷-1,3-二酮的结构5和6鉴定为命中。选定的命中分子用于进一步合成,并合成了四个家族下的37种化合物的文库,用于产生先导。评估抗结核分枝杆菌的文库可鉴定出三种主要的抗结核药(37、39和41)。最有潜力的化合物2-((((2-羟基苯基)氨基)亚甲基)-5,5-二甲基环己烷-1,3-二酮(39)的MIC为2.5 µg / mL,属于MICs范围内。已知的抗结核药物乙胺丁醇,链霉素和左氧氟沙星。此外,该化合物被证明是无毒的(< 在50μM浓度下对4种人类细胞系的抑制率为20%。像一线抗结核药(异烟肼,利福平和吡嗪酰胺)一样,该化合物对一般革兰氏阳性菌和革兰氏阴性菌甚至对耻垢分枝杆菌均无活性。从而反映出其高度特异性的抗结核活性。
