Ixazomib (MLN2238) is a selective, potent, and reversible proteasome inhibitor, which inhibits the chymotrypsin-like proteolytic (β5) site of the 20S proteasome with an IC50 of 3.4 nM (Ki of 0.93 nM).
KZR-616 (KZR616) is a potent, selective dual immunoproteasome subunit LMP7/LMP2 inhibitor with IC50 of 39 nM/139 nM, weakly inhibits β5, MECL-1 and no acitivty against β1 subunit; shows no inhibition at 10 uM against a broad selectivity panel of 20 serine, metallo-, cysteine and aspartyl proteases and 11 hydrolases; demonstrates efficacy in the anti-collagen antibody induced arthritis (CAIA) models. Other Indication Phase 2 Clinical
Proteasome-IN-1 is a proteasome inhibitor extracted from patent WO 2013142376 A1.
Capzimin is a potent and moderately specific proteasome isopeptidase Rpn11 inhibitor.
FiVe1 is a vimentin binding small molecule that promotes vimentin disorganization and phosphorylation during metaphase, causes mitotic catastrophe, multinucleation, and the loss of stemness in cancer cells; selectively and irreversibly inhibits the growth of mesenchymally transformed breast cancer cells ( FOXC2-HMLER cells IC50=234 nM) and soft tissue sarcomas of diverse histological subtypes.
20S Proteasome activator 1 is a potent 20S proteasome activator with EC200 values of 0.3 μM, 0.7 μM and 1.8 μM for trypsin-like site, chymotrypsin-like site and caspase-like site. 20S Proteasome activator 1 translates well in a cellular system, preventing the accumulation of the pathogenic A53T mutant of α-synuclein. 20S Proteasome activator 1 can be used for researching neurodegenerative diseases[1].
Acetyl-Calpastatin(184-210)(human) is a potent, selective and reversible calpain inhibitor with Ki values of 0.2 nM and 6 μM for µ-calpain and cathepsin L, respectively[1][2].
RID-F is an inhibitor of the nonpeptidic proteasome.
Suc-Ala-Ala-Pro-Phe-SBzl can be used as the substrate of rat intestinal mast cell protease (RMCP I), rat skeletal muscle mast cell protease (RMCP II) and Chymotrypsin (HY-108910). Suc-Ala-Ala-Pro-Phe-SBzl can be hydrolyzed by glycine (R208G)[1][2].
Z-Leu-Leu-Tyr-COCHO is a potent chymotrypsin-like activity inhibitor with a Ki value of 3.0 nM[1].
Dazcapistat is a potent calpain inhibitor, with IC50s of <3 μM for calpain 1, calpain 2 and calpain 9, respectively (patent WO2018064119A1, compound 405)[1].
Z-Ala-Arg-Arg-AMC (Fluorogenic Proteasome Substrate) is a fluorogenic substrate for assaying trypsin-like activity of proteasome[1].
ML604440 is a potent, specific and cell permeable proteasome β1i (LMP2) subunit inhibitor[1].ML604440 impairs MHC class I cell surface expression, IL-6 secretion and differentiation of naïve T helper cells to T helper 17 cells. ML604440 strongly ameliorates disease in experimental colitis and EAE[2].
18α-Glycyrrhetinic acid, a diet-derived compound, is an inhibitor of NF-kB and an activator of proteasome, which serves as pro-longevity and anti-aggregation factor in a multicellular organism. 18α-Glycyrrhetinic acid induces apoptosis[1][2].
