Abstract
The present invention relates to new chromogenic amino acid esters and peptide esters of hydroxyisoquinolines and hydroxyquinolines, processes for their preparation 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 particularly used for the detection of leukocytes, in particular in urine.
