Method and product for cleaning and/or whitening of teeth

A method and a product for cleaning and / or whitening of teeth. Natural human cysteine proteinases are employed for cleaning and whitening purposes and this activity can be blocked by natural cysteine protease inhibitors, which are released secondarily from the product at a later stage. The use of natural cysteine proteinases and their inhibitors provides the advantage that they are man's own proteins, and therefore the risk of allegorization is minimized. In addition, their enzyme kinetics are will known.

Cysteine protease capturing agents

InactiveUS20150158931A1Compounds screening/testingBiocideIrreversible bindingProteinase activity
The invention concerns cysteine protease capturing agents capable of highly selective and irreversible binding of the corresponding cysteine protease. Such compounds may have utility in fundamental biological research and diagnostics, e.g. involving labeled or immobilized versions of such compounds, and they may also have potential utility in therapy, based on competitive inhibition of the cysteine protease, as will be readily apparent to those skilled in the art. The present inventors have discovered that such capturing agents can be obtained by modification of a cleavage fragment of a ‘natural’ substrate for the cysteine protease of interest, said modification involving the introduction of a propargyl moiety in such a way that the terminal alkyne group is positioned to allow for interaction with the free thiol group of the cysteine residue at the active site of the protease.
