<p>Peptide derivatives of formula wherein R1 represents a substituted amino goup which is capable of being split orf enzymatically with formation of a colored or fluorescent compound R1 - H. The said peptide derivatives are used for quantitatively assaying the enzyme C1-esterase. The assaying is carried out by reacting a medium which contains C1-esterase or in which the latter is formed or consumed with a peptide derivative as derined above and measuring photometrically, spectrophotometrically, fluorescence-spectrophotometrically or electrochemically the quantity of split product R1 - H released per time unit by the catalytic hydrolytic action of the said enzyme on the peptide derivative.</p> |
