Use of 1-aryl semicarbazides for stabilisation of enzyme substrates, corresponding procedure and diagnostic means containing such stabiliser.

摘要

The invention relates to the use of a 1-arylsemicarbazide of the general formula I Ar-NH-NH-CONH2 (I> in which Ar is an optionally alkyl- alkoxy- or halogen-substituted aryl radical, for the stabilisation of an enzyme substrate from which a leuko dye can be formed by enzymatic hydrolysis and can in turn be converted by an oxidising agent into a dye, to a corresponding stabilisation procedure and to a diagnostic composition containing a stabiliser of this type.
