The antiplasmodial activity, DMPK properties, and efficacy of a series of quinoline-4-carboxamides are described. This series was identified from a phenotypic screen against the blood stage of Plasmodium falciparum (3D7) and displayed moderate potency but with suboptimal physicochemical properties and poor microsomal stability. The screening hit (1, EC50 = 120 nM) was optimized to lead molecules with
描述了一系列 quinoline-4-carboxamides 的抗疟原虫活性、DMPK 特性和功效。该系列是从针对恶性疟原虫 (3D7) 血液阶段的表型筛选中确定的,显示出中等效力,但物理化学性质不理想,微粒体稳定性较差。筛选命中 (1, EC50 = 120 nM) 被优化为具有低纳摩尔体外效力的先导分子。药代动力学特征的改进导致几种化合物在伯氏疟原虫疟疾小鼠模型中显示出优异的口服功效,当口服给药 4 天时,ED90 值低于 1 mg/kg。有利的效力、选择性、DMPK 特性和功效,加上新的作用机制,抑制翻译延伸因子 2 (PfEF2),
