antitubercular activity (MIC: 0.65 µg/mL) almost equal to the Rifampicin, while the rest of the compounds were moderately active against MTB H37Rv except 6b. Compounds 7a and 6b showed good activity against tested fungal pathogens. Compounds 7a and 7b were proven as the best bacterial agents. Molecular docking studies were in agreement with the in-vitro results. Docking analyses show that all the synthesized
本文合成、表征了两个系列的新型多功能 1, 4-二(芳基/杂芳基)取代哌嗪衍生物(6a-d和7a-d),并对其抗结核、抗菌和抗真菌活性进行了评价。对各种醛的逐步还原、溴化和取代反应产生醇(2a-d)、溴化物(3a-d)和标题为中等至良好产率的新型化合物( 6a-d和7a-d) ( 48- 85%)。评价了这些新化合物的抗结核和抗菌活性。化合物7a显示出与利福平几乎相等的有希望的抗结核活性(MIC:0.65 µg/mL),而除6b外,其余化合物对MTB H37Rv具有中等活性。化合物7a和6b对测试的真菌病原体表现出良好的活性。化合物7a和7b被证明是最好的细菌制剂。分子对接研究与体外结果一致。对接分析表明,所有合成的分子都与靶蛋白Mtb RNAP (PDB ID: 5UHC) 相当强地结合。所有化合物都在体外进行了评估使用MTT测定法对人癌细胞系MCF-7的细胞毒性作用。这些化合物显示出对细胞系的生长抑制作用,具有显着的
