Compounds which are substrates for mammalian enzymes, especially proteolytic and peptidase enzymes, are disclosed. These compounds, in general, have the general formula X-T, W-Y or X-(Pep)-Y, wherein X is a radiolabelled benzoyl or hydroxyphenylpropanoyl group, T is the -NH residue of a known chromogenic or fluorogenic substrate comprising at least one amino acid group which may be substituted with other organic groups, Y is a radiolabelled benzylamine group, W is the .
residue of a known chromogenic or fluorogenic substrate comprising at least one amino acid group which may be substituted with other organic groups, and (Pep) is a difunctional or polyfunctional residue from a known chromogenic or fluorogenic substrate comprising at least two amino acid groups in peptide linkage, which residue may be substituted with other organic groups.
