aceturate. In the antimalarial study, 11b was the most active compound, even better than the standard. Molecular docking result suggests good interaction between the reported compounds and the target protein. The results of haematological analysis, liver and kidney function tests showed that the compounds had no adverse effect on the blood and organs. Compound 11b stands out among the derivatives haven shown
疟疾耐药性寄生虫的出现越来越多,锥虫病的有效化学疗法不足,代表了热带地区传染病治疗的巨大挑战。关于开发有效的抗原生动物剂,通过使用肽偶联剂将化合物(10)与(8a-j)缩合,合成了十种新的甘草二肽磺酰胺衍生物。化合物11b,11i和11j最能清除11b小鼠的锥虫布氏锥虫,并具有与醋酸二米那嗪相当的活性。在抗疟疾研究中,11b是活性最高的化合物,甚至优于标准化合物。分子对接结果表明所报道的化合物与靶蛋白之间具有良好的相互作用。血液学分析,肝和肾功能测试的结果表明该化合物对血液和器官没有不良影响。化合物11b在衍生物中脱颖而出,这些衍生物在抗疟和抗锥虫试验中均显示出更好的活性。
