compounds are proved to be non-toxic (with IC50 > 300 μg/mL) as verified through the toxicity evaluation against VERO cell lines. Additionally, molecular docking studies against two target enzymes (Inh A and CYP121) were performed to validate the activity profile of indole-piperazine derivatives. Further, in silico-ADME prediction and pharmacokinetic parameters indicated that these compounds have good oral
在本报告中,通过分子杂交的方法设计了由三组吲哚哌嗪衍生物组成的文库。总共合成了 50 种新的杂合化合物 ( T1-T50 ),并筛选了针对结核分枝杆菌 H37Rv 菌株 (ATCC-27294) 的抗结核活性。 50 种化合物中的 5 种( T36、T43、T44、T48和T49)表现出显着的抑制效力,MIC 为 1.6 µg/mL,比标准一线结核病药物吡嗪酰胺强两倍,与异烟肼等效。与简单衍生物和N-苄基吲哚-哌嗪衍生物相比,N-1,2,3-三唑基吲哚-哌嗪衍生物表现出改善的抑制活性。此外,观察到的吲哚哌嗪类药物对金黄色葡萄球菌、大肠杆菌和铜绿假单胞菌菌株的活性与标准抗结核药物(异烟肼和吡嗪酰胺)相似,表明这些化合物对结核分枝杆菌 H37Rv 菌株具有选择性。通过针对 VERO 细胞系的毒性评估验证,所有活性抗结核化合物均被证明是无毒的(IC 50 > 300 μg/mL)。此外,还针对两种靶酶(Inh
