benzyl N-[(2S)-1-[[(2S)-5-(diaminomethylideneamino)-1-[(4-methyl-2-oxochromen-7-yl)amino]-1-oxopentan-2-yl]amino]-1-oxo-3-phenylpropan-2-yl]carbamate:hydrochloride

Z-Phe-Arg-AMC (70382-26-2) is a fluorogenic substrate1 for the following cathepsins (kcat/Km in M-1s-1): B (105)2, C/DPP-I (104)3, F (106)4, K/O2 (105)3, L (106)3, L2/V (105)5, O6, S (104)7, X/Z (104)8. The peptide is also cleaved by plasma kallikrein and kallikrein 89, and papain (kcat/Km=105 M-1s-1).3?Excitation: 365nm, Emission: 440nm.5

Z-Phe-Arg 7-amido-4-methylcoumarin hydrochloride has been used:

• as a fluorogenic substrate in actinidin inhibition assay
• as a kallikrein substrate
• as a trypsin substrate for fluorometric assay
• as a cathepsin-L substrate

Substrate for fluorogenic assay of plasma and glandular kallikreins. Also serves as a substrate for cathepsin B, cathepsin L, and papain.

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.
