these hybrid molecules. Compound 7d was found to form a stable 1:1 complex with hematin as determined by its Job's plot which suggests that heme may be a probable target of these molecules. Docking studies performed with Pf-DHFR exhibited good binding interactions in the active site. The pharmacokinetic properties of some active compounds were also analysed using ADMET prediction.
合成了一系列基于4-氨基喹啉-嘧啶的新型分子杂合体,并检查了它们的抗疟活性。发现大多数化合物对恶性疟原虫的CQ敏感性D6和CQ抗性W2菌株均具有有效的体外抗疟活性。活性化合物对哺乳动物VERO细胞系没有明显的细胞毒性。与标准药物氯喹相比,有23种化合物对CQ耐药菌株W2表现出更好的抗疟活性,IC 50值在0.0189–0.945μM范围内。研究了最佳活性化合物7d的血红素结合,以发现这些杂合分子的主要作用方式。化合物7d通过其Job's图可确定血红素与血红素形成稳定的1:1络合物,这表明血红素可能是这些分子的靶标。用Pf- DHFR进行的对接研究在活性位点表现出良好的结合相互作用。还使用ADMET预测分析了一些活性化合物的药代动力学特性。
