cycloalka[b]thiophene and indole moieties (TN5, TN5 1-7, TN6, TN6 1-7, TN7, TN7 1-7, TN8, TN8 1-7) were designed, synthesized and evaluated for their cytotoxic and antileishmanial activity against Leishmania amazonensis promastigotes. More than half of the compounds (18 compounds) exhibited significant antileishmanial activity (IC50 lower than 10.0μg/L), showing better performance than the reference drugs (tri- and
在本工作中,设计了32种包含环烷基[b]噻吩和吲哚部分的杂化化合物(TN5,TN5 1-7,TN6,TN6 1-7,TN7,TN7 1-7,TN8,TN8 1-7) ,合成并评估了其对亚马逊利什曼原虫前鞭毛体的细胞毒性和抗疟原虫活性。一半以上的化合物(18种化合物)表现出显着的抗菌活性(IC50低于10.0μg/ L),表现出比参比药物(三价和五价锑)更好的性能。活性最高的化合物是TN8-7,TN6-1和TN7,IC50值分别为2.1、2.3和3.2μg/ mL。证明所有化合物的毒性均低于参考药物,即使在最高评估浓度(400μg/ mL)下,也没有测试的化合物表现出人类红细胞的细胞毒性。化合物TN8-7' 证明了其对三价锑抗性培养物的有效性。观察到TN8-7的抗菌活性与马氏乳杆菌前鞭毛体的DNA片段化有关。化学计量学研究(CPCA,PCA和PLS)强调了固有的溶解度/亲脂性,以及化合物的大
