  • Substrate for the quantitative determination of proteolytic enzymes
    Patent number: 4070245
    Abstract: A substrate for the quantitative determination of enzymes in human and mammal body fluids as well as in animal cell extracts and glandular venoms of cold-blooded animals, which has the structureR.sup.1 -- Gly -- Pro -- X -- NH -- R.sup.2wherein R.sup.1 represents hydrogen or a blocking acyl or sulfonyl group, R.sup.2 represents an aromatic hydrocarbon group which may carry substituents and X represents arginyl or lysyl, --NH--R.sup.2 being a chromogenic or fluorescent group capable of yielding a split product NH.sub.2 --R.sup.2 the quantity of which can be measured by photometric, spectrophotometric or fluorescence-photometric methods.

  • Substrate for the quantitative determination of enzymes
    Patent number: 4016042
    Abstract: A synthetic substrate having the structureR.sup.1 -- Pro -- X -- Y -- NH -- R.sup.2,wherein R.sup.1 is a blocking group, --NH--R.sup.2 is a chromogenic or fluorescent group, X represents a phenylalanyl, .beta.-cyclohexylanyl, phenylglycyl or tyrosyl group, and Y represents a protonized arginyl or lysyl group, is disclosed. This substrate is useful for the quantitative determination of proteolytic enzymes of class E.C. 3.4.4., except thrombin and thrombin-like enzymes.
