A bestatin-based fluorescent probe for aminopeptidase N cell imaging

Aminopeptidase N (APN) is an important drug target and biomarker for various tumors. The current work characterizes a novel APN-targeted fluorescent probe (Bes-Green, 2) that manifests comparable inhibitory activity with Bestatin. This probe has capacity of tightly binding to the APN for imaging endogenous APN in living human ovarian clear cell carcinoma cells (ES-2) and has potential application in biological study of cellular APN.

In this article, a bestatin-based fluorescent probe has been well designed and synthesized for APN cellular imaging.Figure optionsDownload as PowerPoint slide
