NEP162
NEP162 is a BRD4 PROTAC degrader based on the E3 ubiquitin ligase GID4, with DC50 values of 1.2 μM and 1.6 μM in SW480 and U2OS cells, respectively, and a Kd value of 0.13 µM for GID4. NEP162 bridges the E3 ligase GID4 and BRD4 to form a ternary complex, promotes polyubiquitination and subsequent degradation of BRD4 via the ubiquitin-proteasome system, reduces the proliferation capacity of tumor cells and induces apoptosis. NEP162 can be used for research on cancers such as osteosarcoma, colorectal cancer and non-small cell lung cancer.

NEP162 (0.1-20 μM; 6-24 h) induces dose- and time-dependent degradation of BRD4 protein in U2OS and SW480 cells, while it shows no obvious degradation effect in H3122, H520 and HEC-1-A cells[1].
NEP162 (0.5-5 μM; 24 h-7 days) inhibits cell viability, induces apoptosis, and significantly suppresses colony formation in U2OS cells[1].
NEP162 (31.25 nM-3 µM; 180 s association, 180 s dissociation) binds directly to purified recombinant GID4 protein, with a Kd value of 0.13 µM. It induces the formation of a stable ternary complex between purified recombinant GID4 and BRD4BD1 protein, with a Kd value of 0.30 µM[1].
NEP162 (2 μM; 18 h) loses its ability to degrade BRD4 protein in GID4-knockdown SW480 cells[1].
NEP162 (0.2-10 μM; 18 h) promotes the polyubiquitination of BRD4 in U2OS cells that are pre-transfected to express Flag-BRD4 and HA-Ub and pre-treated with MG132 (HY-13259), and it exerts a BRD2-degrading effect without degrading BRD3 protein[1].
