ABSTRACT:
A .gamma.-glutamyl-p-aminoanilide derivative of the formula: ##STR1## wherein R.sup.1 and R.sup.2 are independently lower alkyl; and R.sup.3 is hydrogen, lower alkyl, carboxyl or sulfo, can be produced by reacting a N-phthalyl-.gamma.-glutamyl-p-aminoanilide derivative with hydrazine. The .gamma.-glutamyl-p-aminoanilide derivative can be used as a substrate for measuring .gamma.-glutamyl transpeptidase activity in a living sample.
