Celastrol is a potent proteasome inhibitor [1].Proteasomes are protein complexes that degrading unneeded or damaged proteins by proteolysis.
Celastrol is a potent proteasome inhibitor and an antioxidant, anti-inflammatory and immunosuppressive agent. In a cell-free proteasome activity assay, Celastrol inhibits the chymotrypsin-like activity of a purified rabbit 20S proteasome at 2.5umol and human prostate cancer cellular 26S proteasome at 1-5 μmol. In PC-3 and LNCaP (AR-positive) cells, Celastrol results in the accumulation of ubiquitinated proteins and proteasome substrates (IKB-A, Bax, and p27), and induction of apoptosis [1]. In KBM-5 cells, Celastrol enhances TNF-induced apoptosis by 2% to 92%. In the tumor cells, Celastrol inhibited TNF-induced tumor-cell invasion by 12-fold [2]. In human PBMCs, Celastrol inhibited LPS-induced TNF-α production with IC50 value of 70 nM and LPS-induced IL 113 production with IC50 value of 30nM in a dose-dependent way [3].
In PC-3 tumor–bearing nude mice, Celastrol (1-3 mg/kg/d,1-31 days) inhibited the tumor growth by 65-93% [1].
