Novel compositions of matter of the general formula
A-L-Phe-L-Arg-Y
are described, in which A is lower alkanoyl, pyroglutamyl, substituted with -OH or halogen, and cyclo lower alkanoyls; Y is -OH or a known tag with either radioactive, fluorogenic, chromogenic or chemiluminescent properties.
The compounds of the invention are useful as novel substrates for plasma kallikrein.
A new method of performing the assay for plasma kallikrein is also described.
