Application

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

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.

Actions biochimiques/physiologiques

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

Notes préparatoires

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

Autres remarques

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

Enzymatic Assay of Cathepsin B

Cathepsin B is a lysosomal cysteine proteinase with broad specificity. This protocol uses Nα–CBZ–Arg–Arg–7–amido–4–methylcoumarin as the substrate for fluorometric detection of Cathepsin B activity.
