showed moderate antimalarial activity. Cytotoxicity study was performed against mammalian cell line (Huh-7) by using the MTT assay for the moderately active compounds. Structural activity relationship (SAR) studies displayed that B-ring unsubstituted pyrido[1,2-a]pyrimidine scaffold is responsible for the antimalarial activities of the evaluated derivatives. This SAR based antimalarial screening supported
合成了新型吡啶并[1,2- a ]嘧啶-4-酮,并通过SYBR Green I分析法评估了对氯喹(CQ)敏感的Pf 3D7菌株的促红细胞生成阶段的抗疟活性。对42种不同化合物进行的抗疟疾筛查显示,3-氟苄基(4-oxo-4 H-吡啶基[1,2 -a ]嘧啶-3-基)氨基甲酸酯(21,IC 50值为33μM)和4-Oxo- N -[[4-(三氟甲基)苄基] -4 H-吡啶基[1,2- a ]嘧啶-3-羧酰胺(37,IC 50值37μM)表现出中等抗疟活性。通过对中等活性化合物进行MTT分析,对哺乳动物细胞系(Huh-7)进行了细胞毒性研究。结构活性关系(SAR)研究表明,B环未取代的吡啶并[1,2- a ]嘧啶骨架负责所评估衍生物的抗疟活性。这种基于SAR的抗疟疾筛选方法支持将吡啶并[1,2- a ]嘧啶-4-酮视为主要的杂环结构,以进一步开发更有效的抗疟疾活性衍生物。
