Tripeptide derivatives of the formula in which
X is selected from the group consisting of Pro and Phe Y is selected from the group consisting of O-R, and NH-R 2 in which R, is selected from the group consisting of straight, branched and cyclic alkyl group with 1 -12 C atoms, and R 2 is selected from the group consisting of H, straight, branched and cyclic alkyl group with 1 - 12 C atoms, and physiologically acceptable salts thereof.
A process for producing said tripeptide derivatives by synthesis and purification methods which are known in the peptide chemistry. Pharamaceutical preparations comprising said tripeptide derivatives.
摘要:
Easily split enzyme substrates for the quantification of proteases having the general formula wherein
R 1 = H or a protective group, preferably t-butyl-oxycarbonyl, benzyloxycarbonyl; A, - Gly, Ala, Val, Leu, Ile. Ser, Thr, Pro, Pip, Phe or Tyr; A 2 - Arg or Lys; R 2 = an aromatic, possibly substituted, hydrocarbon group, wherein -NH-R 2 is a physico-chemically determinable group, preferably a chromogenic or fluorogenic group which is split by a present enzyme and then forms a cleavage product of the formula H 2 N - R 2 the amount of which can be quantified.
Process for the production of said substrates. Method in the laboratory diagnostics of proteases using said substrates.
