Malaria, a disease of worldwide significance, is responsible for over one million deaths annually. The liver-stage of Plasmodium’s life cycle is the first, obligatory, but clinically silent step in malaria infection. The P. falciparum type II fatty acid biosynthesis pathway (PfFAS-II) has been found to be essential for complete liver-stage development and has been regarded as a potential antimalarial
疟疾是一种具有全球意义的疾病,每年造成超过一百万的死亡。疟原虫生命周期的肝脏阶段是疟疾感染的第一个必不可少的但临床上沉默的步骤。在恶性疟原虫的II型脂肪酸生物合成途径(Pf的FAS-II)已被发现是完全肝脏阶段发展至关重要,已被视为用于药物的发展为疟疾预防和根除肝脏阶段潜在抗疟药目标。在本文中,报道了新的基于香豆素的三氯生类似物,并根据其对Pf FAS-II途径酶的抑制力来研究其生物学特性。在测试的化合物中,有7和8显示出对Pf烯酰ACP还原酶(Pf FabI)的最高抑制力,其次是15和3。最后,我们确定了与Pf FabI配合的化合物7和11的晶体结构,以鉴定其结合模式并确认对接模拟的结果。
