A new chemotype with promise against Trypanosoma cruzi
摘要:
Pyridyl benzamide 2 is a potent inhibitor of Trypanosoma cruzi, but not other protozoan parasites, and had a selectivity-index of >= 10. The initial structure-activity relationship (SAR) indicates that benzamide and sulfonamide functional groups, and N-methylpiperazine and sterically unhindered 3-pyridyl substructures are required for high activity against T. cruzi. Compound 2 and its active analogs had low to moderate metabolic stabilities in human and mouse liver microsomes.
当前用于构建酰胺键的方法通过脱水偶联过程将胺和羧酸连接起来,该过程通常需要有机溶剂、昂贵且通常危险的偶联试剂,并掩盖其他官能团。在这里,我们描述了使用伯胺和酰基三氟硼酸钾的酰胺形成,由在水中快速进行的简单氯化剂促进。该反应在酸性 pH 值下很快,并且可以耐受底物中的醇、羧酸,甚至仲胺。它适用于伯酰胺、磺酰胺和其他通常抵抗经典酰化的 N 官能团的官能化,并可应用于后期官能化。
