ongoing search for compounds with antimalarial activity, we prepared a series of thiazole analogs and conducted a SAR study analyzing their in vitro activities against the chloroquine-sensitive Plasmodium falciparum 3D7 strain. The results indicate that modifications of the N-aryl amide group linked to the thiazole ring are the most significant in terms of in vitro antimalarial activity, leading to compounds
在我们的药物化学计划不断寻找具有抗疟疾活性的化合物的过程中,我们制备了一系列噻唑类似物,并进行了SAR研究,分析了它们对氯喹敏感的恶性疟原虫3D7菌株的体外活性。结果表明,就体外抗疟活性而言,与噻唑环连接的N-芳基酰胺基团的修饰最为重要,从而导致在HepG2细胞系中具有高抗疟效力和低细胞毒性的化合物。此外,观察到的SAR暗示在苯基环的邻位优选非大体的吸电子基团,而在对位优选小原子如H或F。最后,用吡啶取代苯环,可制得具有相似效价的化合物,
