[Problem] To provide a novel fluorescent probe for dipeptidyl peptidase IV, and a detection method and a detection kit using the fluorescent probe.
[Solution] A fluorescent probe for detecting dipeptidyl peptidase IV (DPP-IV), said probe comprising a compound represented by formula (I) or a salt, thereof. In formula (I): A and B are either the same or different and independently represent an amino acid residue, provided that A is bonded via an amide bond to NH in an adjacent formula and B is bonded via an amide bond to A; R

strategy to obtain activatable fluorescent probes for CPs by utilizing intramolecularspirocyclization of rhodamine to translate the "aliphatic carboxamide to aliphatic carboxylate" structural conversion catalyzed by CPs into dynamic fluorescence activation. Based on this novel strategy, we developed probes for carboxypeptidases A and B. One of these probes was able to detect pancreatic juice leakage
羧肽酶 (CP) 是一类水解酶,可从肽或蛋白质的 C 端切割一个或多个氨基酸。然而,监测 CP 活动的方法并不完善。在这里,我们提出了第一个通用设计策略,通过利用罗丹明的分子内螺环化将 CP 催化的“脂肪族羧酰胺转化为脂肪族羧酸盐”结构转化转化为动态荧光激活,从而获得 CP 的可激活荧光探针。基于这种新策略,我们开发了羧肽酶 A 和 B 的探针。其中一种探针能够检测离体小鼠的胰液渗漏,表明其适用于胰瘘的术中诊断。这种设计策略应该广泛适用于 CP,
