HAT is urgently needed. Leucyl-tRNA synthetase (LeuRS), a recently clinically validated antimicrobial target, is an attractive target for development of antitrypanosomal drugs. In this work, we report a series of α-phenoxy-N-sulfonylphenyl acetamides as T. brucei LeuRS inhibitors. The most potent compound 28g showed an IC50 of 0.70 μM which was 250-fold more potent than the starting hit compound 1. The
由寄生性原生动物锥虫锥虫引起的人类非洲锥虫病(HAT)是热带地区的致命疾病之一,目前的药物不足。因此,迫切需要开发用于HAT的新药。亮氨酰-tRNA合成酶(LeuRS)是最近经过临床验证的抗微生物靶标,是开发抗锥虫病药物的有吸引力的靶标。在这项工作中,我们报告了一系列作为T. brucei LeuRS抑制剂的α-苯氧基-N-磺酰基苯基乙酰胺。最有效的化合物28g的IC50为0.70μM,比起始命中化合物1的IC50强250倍。还讨论了结构-活性关系。这些乙酰胺为进一步开发临床上有用的抗胰锥虫剂提供了新的支架和先导化合物。
