Abstract:
A valylleucyllysine derivative represented by the formula, ##STR1## wherein R.sub.1 represents hydrogen or benzoyl and R.sub.2 represented naphthyl. The above compound is useful as an excellent substrate for various anzymes, such as, trypsin, plasmin, kallikrein, urokinase, Cl-esterase and the like. Accordingly, the activity of enzymes can be measured by use of said compound as a substrate.
