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。

The present invention provides compounds, compositions thereof, and methods of using the same for the inhibition of USP30, and the treatment of USP30-mediated disorders.
This paper describes an optimization strategy of the highly active vinyl ketone 3 which was recognized as a strong inhibitor of rhodesain of Trypanosoma brucei rhodesiense, endowed with a k(second) value of 67 X 10(6) M-1 min(-1) coupled with a high binding affinity (K-i = 38 pM). We now report a new structure-activity relationship study based on structural variations on the P3, P2, and P1' sites which led us to identify two potent lead compounds, i.e., vinyl ketones 4h and 4k. Vinyl ketone 4h showed an impressive potency toward rhodesain (k(second) = 8811 X 10(5)) coupled to a good antiparasitic activity (EC50 = 3.6 mu M), while vinyl ketone 4k proved to possess the highest binding affinity toward the trypanosomal protease (K-i = 0.6 pM) and a submicromolar antiparasitic activity (EC50 = 0.67 mu M), thus representing new lead compounds in the drug discovery process for the treatment of Human African Trypanosomiasis.
