The invention is related to new peptidase substrates of formula (I) :
wherein
- R1 is a peptidyl or amino acid moiety directly linked to W via its carbonyl function or one of its carbonyl functions, or, R1 is a chain R'1-NH-Y-C(0)- in which R'1 is a peptidyl or amino acid moiety directly linked to the NH of the R1 chain via its carbonyl function or one of its carbonyl functions and Y is an organic spacer,
- W is O, NH or NR2 with R2 representing a (C1-C4)alkyl,
- T and Rb are as defined in claim 1.
and a process for detecting the presence of a catalytically active peptidase, using one of such substrates.
