including long duration, variable efficacy and serious side effects, there is an urgent need to explore new antitrypanosomal drugs. The present study describes the hit-to-lead optimization of a 2-aminobenzimidazole hit 1 identified through in vitro phenotypic screening of a chemical library against intracellular Trypanosoma cruzi amastigotes, which focused on optimizing potency, selectivity, microsomal
南美锥虫病是由克氏锥虫引起的一种被忽视的热带病。由于目前的治疗存在一些局限性,包括持续时间长、疗效可变和严重的副作用,因此迫切需要探索新的抗锥虫药物。本研究描述了通过针对细胞内克氏锥虫的化学文库的体外表型筛选鉴定的 2-氨基苯并咪唑命中1的命中到先导优化amastigotes,专注于优化效力、选择性、微粒体稳定性和亲脂性。使用一组 277 个衍生物研究了多参数结构-活性关系。尽管最初命中的物理化学和生物学特性得到改善,但低动力学溶解度和体外对哺乳动物细胞的细胞毒性的结合阻止了最佳化合物的进展,以使用南美锥虫病小鼠模型进行功效研究。
