We have, for the first time, developed a near-infrared fluorescent probe for aminopeptidase N by combining a hemicyanine and an alanyl residue. The probe exhibits high selectivity and sensitivity with a detection limit of 0.8 ng mL. With the probe, aminopeptidase N has been imaged in both cells and mice in vivo, indicating a promising tool for studying the function of the enzyme.
我们首次通过将半菁和丙氨酰残基结合，开发出了一种用于氨肽酶N的近红外荧光探针。该探针具有高选择性和高灵敏度，检测限为0.8 ng/mL。利用该探针，已在体内对细胞和小鼠中的氨肽酶N进行了成像，表明它是研究该酶功能的一种有前景的工具。
