Used as a fluorogenic substrate in enzymatic assays, particularly for detecting dipeptidyl peptidase IV (DPP-IV) activity. The compound releases a fluorescent signal (7-amino-4-methylcoumarin) upon cleavage by DPP-IV and related prolyl peptidases, making it valuable in biochemical and medical research for monitoring enzyme kinetics and inhibition. Its high sensitivity allows detection of low enzyme concentrations in cell lysates, tissue extracts, and diagnostic applications. Commonly employed in high-throughput screening for drug discovery where DPP-IV inhibitors are being evaluated.
