L-Phenylalanine 7-amido-4-methylcoumarin trifluoroacetate salt is a fluorogenic peptide substrate for aminopeptidase. This AMC peptide substrate is normally used to rapidly profile the N-terminal specificity of proteases.

Bis(4-methylumbelliferyl)phosphate is a fluorescent probe that can be used for the diagnosis of β-glucosidase. It has a phosphate group and can be used to study phosphodiesterases and phosphodiesters. Bis(4-methylumbelliferyl)phosphate is also a liposomal probe that can be used in kinetic studies. This compound has been shown to inhibit β-glucosidase, which is an enzyme found in human saliva and pancreatic juice, at high concentrations. The inhibition of this enzyme leads to the accumulation of glucose and galactose in the blood, which can lead to diabetes mellitus or cancer.

L-Ala-PAB-resorufin is a highly sensitive chromogenic and fluorogenic indicator for L-alanine aminopeptidase activity and related enzymes occurring in prokaryotic as well as eukaryotic organisms. After removal of the L-alanyl substructure by enzymatic hydrolysis and spontaneous elimination of the para-aminobenzyl spacer, the initially orange colored compound yields an intense pink color and red fluorescence.
