Opis

Application

Used as matrix for analysis of monosulfated disaccharides and as a co-matrix with 6-aza-2-thiothymidine for sulfated neutral and sialylated tri-and tetrasaccharides.

7-Amino-4-methylcoumarin has been used:

• to determine cathepsin B like- activity
• as a substrate for leucine aminopeptidase (LAP)
• in chymotryptic assay
• as a standard to detect the activation of caspase-3 during
• sanguinarine-induced damage
• protection by human DEAD-box DDX3

Biochem/physiol Actions

7-Amino-4-methylcoumarin is a coumarin derivative, which serves as a fluorescence reference standard to screen protease inhibitors.

Preparation Note

Soluble in DMSO (10 mg/mL), DMF, and acetone (10 mg/mL).

Other Notes

Reagent for preparing new fluorogenic AMC-based substrates for cystine aminopeptidase (and other hydrolases); used as reference compound in the enzyme assay.
