successfully synthesized and built-up four series of 1,2,4-triazole derivatives, containing N,O-disubstituted glycolamide, N,N′-disubstituted glycinamide, β-amino ester, and β-amino amide as linkers, for the development of new dipeptidyl peptidase 4 (DPP-4) inhibitors. The synthetic strategy for glycolamides or glycinamides involved convenient two-steps reaction: functionalized transformation of 2-chloro-N-(2
通过对西格列汀和维格列汀骨架的修饰,我们成功合成并构建了四个系列的1,2,4-三唑衍生物,包括N,O-二取代甘氨酰胺、N,N'-二取代甘氨酰胺、β-氨基酯、和 β-氨基酰胺作为接头,用于开发新的二肽基肽酶 4 (DPP-4) 抑制剂。乙醇酰胺或甘氨酰胺的合成策略涉及方便的两步反应:2-氯-N- (2,4,5-三氟苯基)乙酰胺9 的功能化转化(羟基化或胺化)和 1,2,4-三唑-3-羧酸的酯化或酰胺化。另一方面,开发了包括取代和脱保护在内的一锅合成程序,用于从 (1 H -1,2,4 -triazol-3-yl )甲醇12或 (1 H -1,2,4-三唑-3-基) 甲胺13和 Boc-( R )-3-氨基-4-(2,4,5-三氟-苯基)-丁酸14 . 还针对 DPP-4 抑制活性评估了所有乙醇酰胺、甘氨酰胺和 β-氨基羰基 1,2,4-三唑。基于DPP-4抑制能力的SAR研究,β-氨基酯5n和β-氨基酰胺1
