Celastrol (34157-83-0) displays potent antioxidant and anti-inflammatory activity. Inhibits NFkB (IC50=270 nM).  It induces heat shock response and cytoprotection in various cells. Inhibits 20S proteasome chymotrypsin activity (IC50=2.5 mM). Induces autophagy by targeting AR/miR-101 in prostate cancer cells.4 Induces UPR-dependent cell death in cancer cells.5 Cell permeable.
