Tripterin (Celastrol) is a proteasome inhibitor which potently and preferentially inhibits the chymotrypsin-like activity of a purified 20S proteasome with IC50 of 2.5 μM. Celastrol down-regulated the basal and DNA damaging agents-induced monoubiquitination of FANCD2, followed by proteolytic degradation. Celastrol treatment abrogated the G2 checkpoint induced by IR,and enhanced the ICL agents-induced DNA damage and inhibitory effects on lung cancer cells through depletion of FANCD2.Celastrol presented striking growth inhibition and apoptosis induction potency on DU145 cells in vitro in a time- and dose-dependent manner.Celastrol exhibits its antiprostate cancer effects partially through the downregulation of the expression level of hERG channel in DU145 cells,suggesting that celastrol may be a potential agent against prostate cancer with a mechanism of blocking the hERG channel.Celastrol ameliorates experimental colitis in IL-10 deficient mice via the up-regulation of autophagy by suppressing the PI3K/Akt/mTOR signaling pathway.Celastrol has the potential to inhibit cytochrome P450 activities and may cause the herb-drug interactions.Celastrol induces apoptosis in TNBC cells and indicated that apoptosis might be mediated through mitochondrial dysfunction and PI3K/Akt signaling pathway.
