Gliotoxin
Immunomodulator / A fungal metabolite with immunosuppressive properties; blocks phagocytosis, cytokine production and proliferation of T and B cells.1 Inhibits chymotrypsin-like activity of 20S proteasome preventing IκBα degradation and preventing NF-κB degradation2. Displays antiinflammatory activity3 and blocks leukotriene B4 production via inhibition of LTA4 hydrolase4. It inhibits nuclear NOTCH2 and recovers a tumor-suppressor NOTCH3 activity in chronic lymphocytic leukemia cells.5
