Lapatinib, an approved epidermal growth factor receptor inhibitor, was explored as a starting point for the synthesis of new hits against Trypanosoma brucei, the causative agent of human African trypanosomiasis (HAT). Previous work culminated in 1 (NEU-1953), which was part of a series typically associated with poor aqueous solubility. In this report, we present various medicinal chemistry strategies that
拉帕替尼是一种批准的表皮生长因子受体抑制剂,被用作合成抗非洲锥虫病(HAT)病原体布鲁氏锥虫新药的起点。以前的工作在1(NEU-1953)中达到了高潮,这是通常与水溶性差有关的一系列研究的一部分。在这份报告中,我们介绍了各种药物化学策略,这些策略可用于增加水溶解度和改善理化特性,而又不牺牲抗胰锥虫的药效。为了对锥虫命中的病毒进行分类,建立了一种新的测定方法(总结为杀细胞有效浓度(CEC50)),作为线索选择过程的一部分。增加1的sp3碳含量可得到10e(针对布鲁氏杆菌的EC9为0.19μM,水溶解度为990μM)。对10e的进一步化学探索得到22a,一种锥虫杀喹啉亚胺(EC50:0.013μM;水溶性:880μM; CEC50:0.18μM)。化合物22a在锥虫体感染的小鼠中将寄生虫病降低了109倍;它是HAT药物开发的先进先导。
