infectious diseases, causing hundreds of thousands of deaths each year, primarily in young children and pregnant mothers. Here, we report the discovery and derivatization of a series of pyrazolo[3,4-b]pyridines targeting Plasmodium falciparum, the deadliest species of the malaria parasite. Hit compounds in this series display sub-micromolar in vitro activity against the intraerythrocytic stage of the
疟疾仍然是最致命的传染病之一,每年导致成千上万的死亡,主要是在幼儿和孕妇中。在这里,我们报道了针对恶性疟原虫(疟疾最致命的物种)的一系列吡唑并[3,4- b ]吡啶的发现和衍生化。该系列中的命中化合物在体外显示出亚微摩尔对寄生虫的红细胞内阶段具有高活性,对人成纤维细胞BJ和肝HepG2细胞系几乎没有毒性。此外,我们的命中化合物对寄生虫的肝期表现出良好的活性,但对配子体阶段的活性却很小。包括杀死率,对接率和分子动力学研究在内的寄生虫学资料表明,我们的化合物可能靶向细胞色素bc 1的Q o结合位点。
