In the current paper, three activity-based colorimetric and ratiometric fluorescent probes based on a naphthalimide fluorophore were well designed and synthesized, which can be recognized and hydrolyzed by aminopeptidase N (APN) at both the enzymatic and cellular level by following the fluorescent emission wavelength change from blue to green light. As a result, these molecules were successfully identified as the first ratiometric fluorescent probes for APN cell imaging.
本文以一种萘二甲酰亚胺荧光团为基础,精心设计和合成了三种基于活性的比色法和比率法荧光探针,通过荧光发射波长从蓝光到绿光的变化,氨肽酶 N(APN)可以在酶和细胞水平上识别和水解这些探针。因此,这些分子被成功鉴定为第一种用于 APN 细胞成像的比率荧光探针。
