Field of application
CBK006377 (CBK77) is a small molecule inhibitor of the ubiquitin-proteasome system (UPS) with EC50 of 4.3 uM in MelJuSo Ub-YFP cells (6h treatment).CBK77 (16h treatment, 10 uM) causes an irreversible, global impairment of the UPS collapse, accompanied by a general accumulation of ubiquitylated proteins and caspase-dependent cell death.CBK77 causes a global impairment of ubiquitin-dependent proteasomal degradation without global inhibition of proteasome or DUB activity.NAD(P)H:quinone oxidoreductase 1 (NQO1) is a critical factor for CBK77-mediated UPS impairment, CBK77 is an NQO1 substrate, efficiently metabolized by NQO1.CBK77 reduces growth of NQO1-proficient human cancer cells and xenograft tumors in mice without overt signs of toxicity.

DC29221 PTP1B-IN-9 PTP1B-IN-9 is a ubiquitin-proteasome system (UPS)-stressor. PTP1B-IN-9 inhibits ubiquitin-mediated protein degradation upstream of the 20S proteasomal catalytic activites. PTP1B-IN-9 triggers a ubiquitin-proteasome-system (UPS)-stress response without affecting 20S proteasome catalytic activities. Anticancer activity.
DC11125 TCH-165 TCH-165 is a specific small molecule modulator of proteasome assembly, regulates the dynamic equilibrium between the 20S and 26S proteasome complexes, favoring 20S-mediated protein degradation.
DC10304 RA190 RA190, a bis-benzylidine piperidon, inhibits proteasome function by covalently binding to cysteine 88 of ubiquitin receptor RPN13.
DC4243 ONX-0914 ONX 0914 is an immunoproteasome inhibitor with potential treatment applications in autoimmune disorders, such as rheumatoid arthritis, inflammatory bowel disease and lupus.
DC5086 Ixazomib(MLN2238) MLN2238 inhibits the chymotrypsin-like proteolytic (β5) site of the 20S proteasome with IC50 and Ki of 3.4 nM and 0.93 nM, respectively, also inhibits the caspase-like (β1) and trypsin-like (β2) proteolytic sites, with IC50 of 31 and 3500 nM.
DC77117 Boc3Arg Boc3Arg is the tert-butyl carbamate-protected arginine. Boc3Arg is an efficient tag to induce degradation through directly localizing the protein to the 20S proteasome.
DC74328 WZ-1831 WZ-1831 is a potent and highly selective inhibitor of human constitutive proteasome chymotryptic activity (β5c) with IC50 of 10 nM, >500-fold selectivity over β5i (IC50=7.1 uM).
DC74327 TXS-8 TXS-8 is a specific, small molecule binder of Rpn-6 with KD of 14 uM, Rpn-6 is a subunit of the 19S regulatory particle (RP) of 26s proteasome.
DC74326 TCL-Ester TCL-Ester is the cell-permeable derivative of TCL-1, a non-covalent ligand targeting the Pru domain of Rpn-13.
DC74325 TCL-1 TCL-1 is a non-covalent ligand targeting the Pru domain of Rpn-13, TCL-1 binds to the Pru domain at the Rpn-2 docking site, affects proteasome-mediated proteolysis.
