C25-140

1358099-18-9

C25-140 is a specific, first-in-class small molecule inhibitor of the TRAF6-Ubc13 interaction, binds TRAF6, inhibits TRAF6-Ubc13 interaction and TRAF6 activity; C25-140 effectively reduced TRAF6-mediated ubiquitin chain formation in vitro, impedes NF-κB activation in various immune and inflammatory signaling pathways also in primary human and murine cells; does not effect other E3 ligases (MDM2, TRIM63, ITCH, E6AP and RNF4), also does inhibit E1/E2 reactions.

DI-591

2245887-38-9

DI-591 (DI591) is a potent, selective, cell-permeable inhibitor of the DCN1-UBC12 interaction with Ki of 10-12 nM for human DCN1 and DCN2; displays no affinity against DCN3/4/5 (Ki>10 uM); selectively inhibits neddylation of cullin 3 but has no or minimal effect on neddylation of other cullin family members; accumulates NRF2 protein and its transcriptional activation in cells.

WS-383

2247543-65-1 WS-383 (WS383) is a highly potent, selective, and cellular active inhibitor of DCN1-UBC12 interaction with IC50 of 11 nM; inhibits Cul3/1 neddylation selectively over other cullins and also induces accumulation of p21, p27 and NRF2; exhibits cellular target engagement to DCN1 in MGC-803 cells, enhances the thermal stability of cellular DCN1 protein even at 1 uM

NSC697923

343351-67-7 NSC697923 (NSC 697923) is a small molecule that specifically inhibits the activity of the ubiquitin-conjugating (E2) enzyme Ubc13 (UBE2N)-Uev1A; NSC697923 impedes the formation of the Ubc13 and ubiquitin thioester conjugate and suppresses constitutive NF-κB activity in ABC-DLBCL cells, inhibits NF-κB activation induced by PMA, but not by TNFα; specifically inhibits Ubc13-mediated polyubiquitin chain synthesis in vitro, does not inhibits UbcH5c-mediated polyubiquitin chain formation; inhibits the proliferation and survival of ABC-DLBCL cells and GCB-DLBCL cells.

UBE2M-DCN1 inhibitor 52

2089293-14-9 UBE2M-DCN1 inhibitor 52 is a highly potent inhibitor of DCN1-UBE2M protein-protein interaction with IC50 of 60 nM, inhibits cullin neddylation in pulse-chase NEDD8 transfer assay with EC50 of 80 nM; binds to DCN1 and selectively reduce steady-state levels of neddylated CUL1 and CUL3 in a squamous cell carcinoma cell line, inhibits DCN1 but not DCN3 stimulated NEDD8 transfer from UBE2F to the cullins.
