Abstract
The invention relates to chromogenic compounds and the use thereof for the determination of enzymes of the family of carboxypeptidases N and carboxypeptidases U. The above is more specifically a compound of formula (I) in which A=(1), (2), (3), (4) or (5), R1, R2=H, —CH3, —CH(CH3)2, —OCH3, —Cl,—CF3,—OCF3,—SCH3, R3=an amino acid group which may be hydrolysed by a carboxypeptidase A and R4=a basic amino acid group.
