4a-y and indole intermediates 3a-e were synthesized using multicomponent one pot reaction. The synthesized compounds were subjected to screening for antimalarial activity against chloroquine sensitive (D6) and chloroquine resistant (W2) strains of Plasmodium falciparum. Several compounds exhibited antimalarial activity with IC50 values in the range of 1.47-9.23 μM, and 1.16-7.66 μM, for D6 and W2 strains
使用基于片段的设计策略,使用多组分一锅反应合成了新的吡啶基-吲哚杂化物4a-y和吲哚中间体3a-e。对合成的化合物进行了针对恶性疟原虫的氯喹敏感性(D6)和氯喹抗性(W2)菌株的抗疟疾活性筛选。几种化合物显示出抗疟疾活性,对于D6和W2菌株,IC50值分别在1.47-9.23μM和1.16-7.66μM范围内。在所有测试的化合物中,化合物4a,4k和4u显示出最高的选择性指数(SI范围为3.8-10)。使用分子对接分析研究了活性抗疟化合物与四倍突变型恶性疟原虫二氢叶酸还原酶的活性位点之间的结合相互作用。
