USP7-IN-18

USP7-IN-18 is a naphthalene derivative. USP7-IN-18 is a selective USP7 inhibitor (IC50 : 130.9 nM), with no or very weak inhibition of the other 8 DUBs including USP47. USP7-IN-18 specifically binds to the catalytic domain of USP7, blocking its deubiquitinase activity. USP7-IN-18 causes degradation of the oncogenic proteins MDM2 and DNMT1, and also degrades the novel target PCLAF. USP7-IN-18 activates the p53-p21 pathway. USP7-IN-18 exerts anti-tumor effects in colon cancer animal models and reshapes the tumor immune microenvironment. USP7-IN-18 achieves both direct cytotoxic and immune-synergistic anti-tumor actions[1].
