Proteasome Proteasome

Cat.No.  Name Information
M3884 Celastrol Celastrol (Tripterin) is a potent antioxidant and anti-inflammatory agent, as well as a proteasome inhibitor which potently and preferentially inhibits the chymotrypsin-like activity of a purified 20S proteasome with IC50 of 2.5 μM.
M2193 Epoxomicin Epoxomicin (BU-4061T) is a cell-permeable, selective and irreversible proteasome inhibitor with an IC50 value of 4 nM. Epoxomicin covalently binds to the LMP7, X, MECL1, and Z catalytic subunits of the proteasome and potently inhibits primarily the chymotrypsin-like activity. Epoxomicin can cross the blood-brain barrier.
M2071 ONX-0914 Onx-0914 (PR-957) is a selective inhibitor of low molecular weight polypeptide 7 (LMP7), a chymotrypsin subunit of the immune proteasome. Onx-0914 blocks cytokine production and reduces the progression of experimental arthritis. Onx-0914 is a non-competitive irreversible inhibitor of mycobacterium proteasome (Ki=5.2 μM). Onx-0914 activates latent HIV-1 through HF-1-mediated p-TEFb activation.
M2035 IU1 IU1 is a reversible, small molecule inhibitor of deubiquitination by USP14 that demonstrates an IC50 value of 4-5 μM.
M1902 MG132 MG132 is a specific and potent cell-permeable proteasome inhibitor (IC50 = 100 nM, Ki = 4 nM). MG-132 effectively blocks the proteolytic activity of the 26S proteasome complex. MG-132 is also a calpain inhibitor with IC50 of 1.2 μM.
M1686 Bortezomib (PS-341) Bortezomib (PS-341) is a highly selective proteasome inhibitor with a ki value of 6nM.
M66250 MV151 MV151 is a cell-permeable, fluorescent, broad-spectrum proteasome inhibitor that specifically targets all active subunits of the proteasome and immunoproteasome in living cells and can be used to label the proteasome in vitro and in vivo.
M59302 BT317 BT317 is a blood-brain transmissible mitochondrial Lon peptidase I (LonP1) and CT-L proteasome inhibitor. BT317 can increase the production of reactive oxygen species (ROS) and induce apoptosis in astrocytoma cells. BT317 has antitumor activity.
M28190 MG-115  MG-115 is a potent and reversible proteasome inhibitor, with Kis of 21 nM and 35 nM for 20S and 26S proteasome, respectively. MG-115 specifically inhibit the chymotrypsin-like activity of the proteasome, induces p53-dependent apoptosis.
M27794 ALLM ALLM (Calpain inhibitor II) is a potent inhibitor of calpain and cathepsin proteases. ALLM inhibits neuronal cell death and improves chronic neurological function after spinal cord injury (SCI).
M14519 ONX-0914 TFA ONX-0914 (PR-957) TFA is a selective inhibitor of low-molecular mass polypeptide-7 (LMP7), the chymotrypsin-like subunit of the immunoproteasome.
M14517 Capzimin Capzimin is a potent and moderately specific proteasome isopeptidase Rpn11 inhibitor.
M13366 (R)-MG-132 (R)-MG-132 (Z-LEu-LEu-Al) is a cellular permeable proteasome and Calpain inhibitor with IC50 of 100 nM and 1.2 μM, respectively.
M11459 ML604440 ML604440 is a potent, specific and cell-permeable inhibitor of the proteasome β 1I (LMP2) subunit. ML604440 disrupts MHC class I cell surface expression, IL-6 secretion and naive T helper differentiation to 17 T helper cells. ML604440 improves experimental colitis and EAE disease.
M11402 TCH-165 Tch-165 is a small molecule modulator of proteasome assembly that increases 20S levels and promotes 20S-mediated protein degradation.
M9577 RA190 hydrochloride RA190 HCl is a potent RPN13 and ADRM1 Inhibitor, inhibits proteasome function by covalently binding to cysteine 88 of ubiquitin receptor RPN13.
M9570 RAMB4 RAMB4 (PTP1B-IN-9) is a ubiquitin-proteasome system (UPS)-stressor with anticancer activity. RAMB4 inhibits ubiquitin-mediated protein degradation upstream of the 20S proteasomal catalytic activites. RAMB4 triggers a ubiquitin-proteasome-system (UPS)-stress response without affecting 20S proteasome catalytic activities.
M7764 PD150606 PD150606 is a selective, cellular permeable non-peptide calpain inhibitor with Ki of 0.21 μ m and 0.37 μ m on μ-calpains and M-calpains, respectively, and has neuroprotective activity.
M5221 MG-101 MG-101 is a potent inhibitor of cysteine proteases including calpain I (Ki = 190 nM), calpain II (Ki = 220 nM), cathepsin B (Ki = 150 nM), and cathepsin L (Ki = 500 pM). IC50 value: 150 nM (Ki)
M4985 VR23 VR23 is a small molecule that potently inhibited the activities of trypsin-like proteasomes (IC50 = 1 nM), chymotrypsin-like proteasomes (IC50 = 50-100 nM), and caspase-like proteasomes (IC50 = 3 μM).
