Mca-EVKMDAEF-K(Dnp)-NH2 ammonium salt

Mca-EVKMDAEF-K(Dnp)-NH2 ammonium salt is a fluorogenic peptide substrate designed for the study of enzymatic cleavage, particularly protease activity. It consists of a peptide sequence labeled with a 7-methoxycoumarin-4-acetyl (Mca) fluorophore and a dinitrophenyl (Dnp) quencher on opposite ends. Upon cleavage by specific proteases, the quenching is relieved, resulting in measurable fluorescence that provides insight into enzymatic kinetics.

This compound is widely used in enzymology studies to assess protease activity. Its fluorescence-based detection allows real-time monitoring of cleavage events, making it valuable for studying enzyme kinetics, substrate specificity, and inhibitor screening.

Mca-EVKMDAEF-K(Dnp)-NH2 is instrumental in drug discovery, particularly in developing protease inhibitors. By providing a reliable assay to evaluate the effectiveness of potential inhibitors, it supports the identification of therapeutic candidates for diseases involving dysregulated protease activity, such as cancer and viral infections.

This peptide is extensively utilized in biochemical research to understand the substrate preferences of proteases. Its well-defined sequence and fluorescence properties enable researchers to dissect the mechanistic details of proteolytic processes and identify key interaction motifs.

The compound also serves in high-throughput screening (HTS) platforms for enzyme activity and inhibitor testing. Its fluorescence-based assay compatibility makes it ideal for large-scale studies, accelerating the evaluation of numerous compounds in pharmaceutical and academic research.
