The synthesis of triazole-linked glycosyl acetophenone, benzoic acid, and α-ketocarboxylic acid derivatives was readily achieved via Cu(I)-catalyzed azide-alkyne cycloaddition ('click' reaction) in excellent yields of 93-97%. Among the synthesized glycoconjugates, the triazolyl α-ketocarboxylic acids were identified as the most potent protein tyrosine phosphatase 1B (PTP1B) inhibitors with micromole-ranged
三唑连接的糖基苯乙酮,苯甲酸和α-酮羧酸衍生物的合成很容易通过Cu(I)催化的叠氮化物-炔烃环加成反应(“点击”反应)完成,产率高达93-97%。在合成的糖缀合物中,三唑基α-酮羧酸被认为是最有效的蛋白酪氨酸磷酸酶1B(PTP1B)抑制剂,在一系列包括TCPTP( 4.6倍),LAR(> 30倍),SHP-1(> 30倍)和SHP-2(> 30倍)。此外,进行对接模拟以提出葡糖基α-酮羧酸三唑与酶促靶标的合理结合模式。
