E3 ligase Ligand 23 is a cereblon binding agent that degrades Ikaros or Aiolos via the ubiquitin proteasome.

Gabexate mesylate (FOY) is a serine proteinase inhibitor used therapeutically in the treatment of pancreatitis, disseminated intravascular coagulation (DIC), and as a regional anticoagulant for hemodialysis. The drug inhibits the hydrolytic effects of thrombin, plasmin, and kallikrein, but not of chymotrypsin and aprotinin.

Carfilzomib (PR-171) is a proteasome inhibitor that irreversibly binds to the chymotrypsin of the 20S proteasome. Carfilzomib has antitumor activity and may be used to treat multiple myeloma.

Tripterin (Celastrol) is a natural product, a proteasome inhibitor that inhibits the pancreatic rennet-like activity of the 20S proteasome (IC50=2.5 μM). Tripterin has anti-inflammatory, anti-infectious, and immunomodulatory properties.

Alloxan Monohydrate is a diabetogenic agent that acts as a proteasome inhibitor and induces diabetes in experimental animals by damaging the insulin-secreting β-cells in the pancreas. It is commonly used to establish diabetes models.

4'-Hydroxychalcone (2-Benzal-4-Hydroxyacetophenone) is a chalcone metabolite with hepatoprotective activity
