FT827 is a selective and covalent ubiquitin-specific protease 7 (USP7) inhibitor (Ki=4.2 ?M). FT827 binds to the USP7 catalytic domain (USP7CD; residues 208-560) with an apparent Kd value of 7.8 ?M.
CC0651 is an allosteric inhibitor of the human Cdc34 ubiquitin-conjugating enzyme. CC0651 potently (IC50=1.72 μM) inhibits the ubiquitination of p27Kip1, as confirmed by dose-response analysis.
