GNE-6640

GNE-6640 (GNE6640) is a potent, selective USP7 inhibitor with IC50 of 0.75 uM; dislpalys selectivity over USP47 and USP5 (IC50>200 uM); promotes endogenous MDM2 ubiquitination, stabilized p53 and upregulated p21, induces tumour cell death and enhances cytotoxicity with chemotherapeutic agents and targeted compounds, including PIM kinase inhibitors; decreased viability of 108 cell lines with IC50 <10 uM.(In Vitro):GNE-6640 promotes endogenous MDM2 ubiquitination with Lys48 (K48)-linked polyubiquitin chains, which directs proteasomal degradation13. GNE-6640 targets cellular USP7, MDM2, and p53 signalling pathways. GNE-6640 decreases viability of 108 cell lines with IC50 ≤ 10 μM. Combining GNE-6640 with doxorubicin or cisplatin (DNA-damaging agents), which could activate the p53 response and enhance USP7 inhibitor efficacy. GNE-6640 could induce tumor cell death. GNE-6640 enhances cytotoxicity with chemotherapeutic agents and targeted compounds, including PIM kinase inhibitors.
