Chromogenic peptide substrates for serine proteases have been designed by using two approaches: (1) by using the natural substrate as a model and (2) by structure-activity correlations obtained through screening of a large number of tripeptides. Some recent examples, substrates for kallikreins and urokinase are given.
The factor Xa-sensitive substrate BZ-Ile-Glu-Gly-Arg-p-nitroanilide has been made more sensitive by making ester and amide derivatives of the gamma-carboxyl group of the glutamyl residue. The morpholinyl and piperidyl amides react 2.5 times more rapidly with factor Xa.

The chromogenic substrate S-2251 (H-D-Val-Leu-Lys-pNA), a selective and sensitive substrate for plasmin activity, has made it possible to develop simple and reproducible methods for the determination of antiplasmin and plasminogen in human plasma. These methods have been optimized and studied in detail and found to be very specific for the respective factors.
