A high-throughput (HTS) and high-content screening (HCS) campaign of a commercial library identified 2-acetamidothophen-3-carboxamide as a novel scaffold for developing new anti-leishmanial agents. A series of chemical modifications were performed to study the structure–activity relationship (SAR) and in vitro anti-leishmanial activities were evaluated using biological assays of not only extracellular promastigotes but also intracellular amastigotes. Compound 6a showed promising anti-amastigote activity (EC50 = 6.41 μM) against L. donovani without any cytotoxicity (CC50 > 50 μM) towards human macrophages.
商业图书馆的高通量(HTS)和高内涵筛选(HCS)活动确定了 2-acetamidothophen-3-carboxamide 作为开发新型抗利什曼病药物的新型支架。进行了一系列化学修饰来研究构效关系(SAR),并使用细胞外前鞭毛体和细胞内无鞭毛体的生物测定来评估体外抗利什曼原虫活性。化合物 6a 对杜氏乳杆菌表现出良好的抗无鞭毛体活性 (EC50 = 6.41 μM),而对人巨噬细胞没有任何细胞毒性 (CC50 > 50 μM)。
