Z-Phe-Arg 7-amido-4-methylcoumarin hydrochloride has been used:as a fluorogenic substrate in actinidin inhibition assayas a kallikrein substrateas a trypsin substrate for fluorometric assayas a cathepsin-L substrate
Biochem/physiol Actions
Z-Phe-Arg 7-amido-4-methylcoumarin (Z-FR-AMC) proteolytic lysis by proteases leads to the liberation of AMC resulting in increased fluorescence in the enzymatic reaction.
General description
Z-Phe-Arg 7-amido-4-methylcoumarin (Z-FR-AMC) is a peptidomimetic substrate for papainand other enzymes such as cathepsin K. It is also a fluorogenic synthetic peptide for the enzymes cathepsins L and B.
