S1013 Bortezomib (PS-341) Bortezomib (PS-341) is a potent 20S proteasome inhibitor with Ki of 0.6 nM. Selective 20S proteasome, Ki: 0.6 nM
S2181 MLN9708 MLN9708 immediately hydrolyzed to MLN2238, the biologically active form, on exposure to aqueous solutions or plasma. MLN2238 inhibits the chymotrypsin-like proteolytic (β5) site of the 20S proteasome with IC50/Ki of 3.4 nM/0.93 nM, less potent to β1 and little activity to β2. Phase 3. Selective 20S proteasome, IC50: 3.4 nM; 20S proteasome, Ki: 0.93 nM
S2180 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. Phase 3. Selective 20S proteasome, Ki: 0.93 nM; 20S proteasome, IC50: 3.4 nM
S1157 CEP-18770 (Delanzomib) CEP-18770 (Delanzomib) is an orally active inhibitor of the chymotrypsin-like activity of proteasome with IC50 of 3.8 nM, with only marginal inhibition of the tryptic and peptidylglutamyl activities of the proteosome. Phase 1/2. Selective Chymotrypsin-like proteasome, IC50: 3.8 nM
S7172 ONX-0914 (PR-957) ONX-0914 (PR-957) is a potent and selective immunoproteasome inhibitor with minimal cross-reactivity for the constitutive proteasome. Selective LMP7, IC50: ~10 nM
S7462 PI-1840 PI-1840 is a reversible and selective chymotrypsin-like (CT-L) inhibitor with IC50 of 27 nM with little effects on the other two major proteasome proteolytic activities, trypsin-like (T-L) and postglutamyl-peptide-hydrolysis-like (PGPH-L). Selective Chymotrypsin-like proteasome, IC50: 27 nM
S7049 Oprozomib (ONX 0912) Oprozomib (ONX 0912) is an orally bioavailable inhibitor for CT-L activity of 20S proteasome β5/LMP7 with IC50 of 36 nM/82 nM. Phase 1/2. Selective 20S proteasome β5, IC50: 36 nM; 20S proteasome LMP7, IC50: 82 nM
S1290 Celastrol Celastrol is a potent proteasome inhibitor for the chymotrypsin-like activity of a purified 20S proteasome with IC50 of 2.5 μM. Selective 20S proteasome, IC50: 2.5 μM; 20S proteasome, :
