GNE 6640 是一种选择性泛素特异性肽酶 7(USP7)的非共价抑制剂，其对全长USP7、USP7 催化结构域、全长USP43 以及 Ub-Mdm2 的IC50值分别为 0.75 μM、0.43 μM、20.3 μM 和 0.23 μM。

GNE-6640 is a non-covalent inhibitor of ubiquitin epecific peptidase 7 (USP7), with IC50 values of 0.75 μM, 0.43 μM, 20.3 μM and 0.23 μM for full length USP7, USP7 catalytic domain, full length USP43 and Ub-MDM2, respectively.

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.
