理想情况下,可以开发针对生命周期多个阶段的抗疟药物,从而影响疾病的预防、治疗和传播。在这里,我们介绍4-(1H)-喹诺酮-3-二芳基醚,是选择性有效的寄生虫的线粒体细胞色素bc 1复合物的抑制剂。这些化合物对原发性人类疟疾(恶性疟原虫和间日疟原虫)具有高度活性,靶向肝脏和血液阶段的寄生虫以及对疾病传播至关重要的形式:配子体、合子、动合子、卵囊。被选为临床前候选药物的ELQ-300在小鼠中以有效剂量具有良好的口服生物利用度,代谢稳定,并且在啮齿动物疟疾模型中具有高度活性。鉴于患者的预期剂量较低,预期半衰期较长,ELQ-300为治疗、预防并最终根除疟疾提供了新分子的希望。
Ideally antimalarial drugs can be developed which target multiple life cycle stages, thus impacting prevention, treatment and transmission of disease. Here we introduce 4-(1H)-quinolone-3-diarylethers that are selectively potent inhibitors of the parasite’s mitochondrial cytochrome bc1 complex. These compounds are highly active against the primary human malarias (falciparum and vivax), targeting the parasite at both the liver and blood stages as well as the forms that are crucial to disease transmission: gametocytes ⇒ zygotes ⇒ ookinetes ⇒ oocysts. Chosen as the preclinical candidate, ELQ-300 has good oral bioavailability at efficacious dosages in mice, is metabolically stable, and is highly active in rodent malaria models. Given a low predicted dose in patients and a long predicted half-life, ELQ-300 offers the hope of a new molecule for the treatment, prevention and, ultimately, eradication of malaria.
