Malarial aspartic protease, plasmepsin (Plm), is perspective antimalarial drug target. Following up our previosly identified 2-aminoquinazolin-4(3H)-one-based inhibitors, 2-aminopyrido[2,3-d]-, -[3,2-d]-, and -[4,3-d]pyrimidin-4(3H)-ones bearing subpocket-specific substituents at position 7 were prepared and tested for their Plm I, II, IV inhibition potency. The position of the nitrogen atom in 2-
疟疾天冬氨酸蛋白酶,纤溶酶(Plm)是抗疟疾药物的靶标。跟进我们以前确定的基于2-氨基喹唑啉-4(3 H)-one的抑制剂,2-氨基吡啶[2,3- d ]-,-[3,2- d ]-和-[4,3- d制备在位置7带有亚口袋特异性取代基的]嘧啶-4(3 H)-并测试其对Plm I,II,IV的抑制能力。2-氨基吡啶并嘧啶酮中氮原子的位置在对Plms的抑制效力中起重要作用。吡咯并[2,3- d ]嘧啶-4(3 H)-one衍生物显示对Plms I,II,IV的抑制作用较弱,而与位置7处的取代基无关。但是,吡啶并[4,3-d ] pyrimidin-4(3 H)-ones和吡啶并[3,2- d ] pyrimidin-4(3 H)-ones更适合用于Plm抑制剂的开发。特别地,2-氨基-7- [4-(3-苯基丙基)苯基] -3-[(四氢呋喃-2-基)甲基]吡啶基[3,2 - d ]嘧啶-4(3 H)-显示非常好。对Plm
