at the maximum concentration evaluated. Again, the synthesized compounds were found to have potential antifungal activity. Furthermore, to rationalize the observed biological activity data, the molecular docking study also been carried out against a potential target Zmp1 enzyme of MTB H37Ra, which revealed a significant correlation between the binding score and biological activity for these compounds
为寻找针对结核分枝杆菌(MTB)H37Ra和牛分枝杆菌BCG的新活性分子,已通过使用[HDBU] [HSO4]酸性离子液体有效地合成了含有罗丹宁的四氮杂喹啉的小分子文库。发现化合物3c是有希望的MTB H37Ra和牛分枝杆菌BCG抑制剂,其MIC值分别较低,分别为4.5和2.0mug / mL。使用MTT测定法进一步测试了活性化合物对HeLa,THP-1,A549和PANC-1细胞系的细胞毒性,并且在所评估的最大浓度下没有显示出明显的细胞毒性活性。同样,发现合成的化合物具有潜在的抗真菌活性。此外,为了合理化观察到的生物活性数据,还针对MTB H37Ra的潜在靶标Zmp1酶进行了分子对接研究,这揭示了这些化合物的结合得分和生物学活性之间的显着相关性。体外和计算机模拟研究的结果表明,这些化合物具有进一步开发新型治疗剂的理想结构要求。
