new and potent antimalarial drugs, we designed the virtual library with three points of randomization of novel [1,2,4]triazolo[4,3-a]pyridines bearing a sulfonamide fragment. The library of 1561 compounds has been investigated by both virtual screening and molecular docking methods using falcipain-2 as a target enzyme. 25 chosen hits were synthesized and evaluated for their antimalarial activity in vitro
为了开发新的和有效的抗疟疾药物,我们设计了虚拟库,其中包含带有磺胺片段的新型 [1,2,4] 三唑并 [4,3-a] 吡啶的三个随机点。使用 falcipain-2 作为目标酶,通过虚拟筛选和分子对接方法对 1561 种化合物的库进行了研究。合成了 25 个选定的命中并评估了它们在体外针对恶性疟原虫的抗疟活性。3-乙基-N-(3-氟苄基)-N-(4-甲氧基苯基)-[1,2,4]三唑并[4,3-a]吡啶-6-磺酰胺和2-(3-氯苄基)-8 -(piperidin-1-ylsulfonyl)-[1,2,4]triazolo[4,3-a]pyridin-3(2H)-one 显示出良好的体外抗疟活性,抑制浓度 IC50 分别为 2.24 和 4.98 μM。
