plant-derived naturalproduct 14-hydroxy-6,12-muuroloadien-15-oic acid (1) was identified as a unique scaffold that could be chemically elaborated to generate novel lead- or drug-like screening libraries. Prior to synthesis a virtual library was generated and prioritised based on drug-like physicochemical parameters such as log P, log D5.5, hydrogen bond donors/acceptors, and molecular weight. The natural product
植物来源的天然产物14-羟基-6,12-muuroloadien-15-oic acid(1)被鉴定为独特的支架,可以对其进行化学修饰以生成新颖的铅或药物样筛选库。在合成之前,基于类药物的物理化学参数(例如log P,log D 5.5,氢键供体/受体和分子量)生成虚拟库并确定其优先级。天然产物支架(1)分离自澳大利亚特有植物Eremophila mitchellii然后用于两个系列类似物的并行溶液阶段生成。第一个库包含六个半合成酰胺衍生物,而第二个库包含六个氨基甲酸酯类似物。使用氯喹敏感的恶性疟原虫品系(3D7)对这些文库的抗疟疾活性进行了评估,几种化合物表现出低至中等活性,IC 50值为14至33μM。
