CHROMOGENIC ESTERS OF AMINO ACIDS AND PEPTIDES, PROCESSES FOR THEIR PREPARATION, USE OF THESE AGENTS IN METHODS OF ANALYSIS AND AGENTS FOR DETECTION OF ESTEROLYTIC AND/OR PROTEOLYTIC ENZYMES

摘要

The present invention relates to new chromogenic amino acid esters and peptide esters of hydroxybenzo(iso)thiazoles and hydroxybenzopyrazoles and the use of the new esters as substrates for the analytical detection of esterolytic and/or proteolytic enzymes, for example in body fluids, the esters being incorporated into test agents, in particular test strips, in a suitable manner. The new esters are preferably used for the detection of leukocytes, in particular in urine.
