Next, the inhibitory activity against P. falciparum of 18 compounds were tested, founding six compounds with IC50 < 20 µM. The most active of these compounds was 8c; however, their unsaturated derivative 7c was inactive. Then, a structure-activity relationship analysis was done, founding that focused LUMO lobe on the specific molecular zone is related to inhibitory activity against P. falciparum.
摘要 疟疾是一种传染病,影响第三世界国家的弱势群体。受天然产物的启发,吲哚生物碱已被用作设计新抗疟药物的核心。因此,以中等至优异的产率获得了十八种羟吲哚衍生物、氮杂类似物。此外,通过H 2 /Pd/C 还原得到的羟吲哚和氮杂衍生物的饱和衍生物以良好的收率获得,导致每种化合物的外消旋混合物。接下来,测试了 18 种化合物对恶性疟原虫的抑制活性,发现 6 种化合物的 IC 50 < 20 µM。这些化合物中最活跃的是8c; 然而,它们的不饱和衍生物7c没有活性。然后,进行构效关系分析,发现LUMO叶聚焦在特定分子区与对恶性疟原虫的抑制活性有关。最后,我们使用分子对接虚拟筛选发现了羟吲哚衍生物对乳酸脱氢酶的潜在抑制作用。
