In a previous study, target based screening was carried out for inhibitors of β-hematin (synthetic hemozoin) formation, and a series of triarylimidazoles were identified as active against Plasmodium falciparum. Here, we report the subsequent synthesis and testing of derivatives with varying substituents on the three phenyl rings for this series. The results indicated that a 2-hydroxy-1,3-dimethoxy
在先前的研究中,针对β-血凝素(合成血红蛋白)形成的抑制剂进行了基于靶点的筛选,并且鉴定出了一系列三芳基咪唑对恶性疟原虫具有活性。在这里,我们报告了该系列三个苯环上具有不同取代基的衍生物的后续合成和测试。结果表明,亚微摩尔寄生虫活性需要环A上的2-羟基-1,3-二甲氧基取代模式。此外,细胞分离研究显示,恶性疟原虫细胞内可交换(游离)血红素异常大,剂量依赖性增加,这与β-血红素抑制衍生物的寄生虫存活率降低有关。
