treatment regimens. A library of 1.8 million compounds, from which the hits reported here are publicly available, was screened against Leishmania infantum as part of an optimization program; a compound was found with a 2-aminobenzimidazole functionality presenting moderate potency, low metabolic stability and high lipophilicity. Several rounds of synthesis were performed to incorporate chemical groups
利什曼病是一种主要的传染病,每年有成千上万的新病例,死亡人数超过20,000。当前用于治疗这种威胁生命的感染的药物具有一些缺点,例如毒性和长期的治疗方案。作为优化计划的一部分,针对婴儿利什曼原虫筛选了180万种化合物的库,可以从此处公开报道点击率。发现具有2-氨基苯并咪唑官能度的化合物具有中等效力,低代谢稳定性和高亲脂性。进行了几轮合成以结合能够降低亲脂性和清除率的化学基团,从而鉴定出对不同寄生虫菌株具有活性并具有改进的体外特性的化合物。这项优化计划的结果是,为了预期体内评估,进一步测试了一组化合物。用化合物29(婴儿乳IC50:4.1μM)和39(婴儿乳IC50:0.5μM)在急性婴儿VL小鼠模型中进行了体内测试,结果显示暴露不良且缺乏功效的问题,尽管具有良好的体外效能。
