ENR performed using Surflex-Dock in Sybyl-X 2.0 software indicates the occupation of substituted pyrrolyl derivatives into hydrophobic pocket of InhA enzyme. Compounds 9b and 9d exhibited the highest antitubercular activity almost close to isoniazid (0.4 μg/mL) with a MIC value of 0.8 μg/mL. All other compounds showed the good activity with a MIC value of 6.25-100 μg/mL. The compounds were further tested
我们在这里报告了61个带有吡唑啉,异恶唑和苯基硫脲部分的新型吡咯基衍生物的合成,抗菌和抗结核评估。使用Surflex-Dock对结核分枝杆菌的烯酰ACP还原酶进行了分子对接,Surflex-Dock是参与结核分枝杆菌II型脂肪酸生物合成途径的关键酶之一,这是设计新型抗结核药的有吸引力的靶标。使用Sybyl-X 2.0软件中的Surflex-Dock对ENR的晶体结构进行对接分析,表明取代的吡咯基衍生物已进入InhA酶的疏水口袋中。化合物9b和9d表现出最高的抗结核活性,几乎接近异烟肼(0.4μg/ mL),MIC值为0.8μg/ mL。所有其他化合物均显示出良好的活性,MIC值为6.25-100μg/ mL。使用人肺癌细胞系(A549)对化合物的哺乳动物细胞毒性进行了进一步测试,并且该化合物无毒。一些化合物表现出对InhA的抑制活性。
