Biological Activity

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.

Cell Experiment
Cell lines RPMI 8226, KATOIII, UM-SCC1, U251MG and MDA-MB-231 cells
Preparation method Determining the anti-proliferative effect of celastrol on various human tumor cell lines by the MTT uptake method. Briefly, incubating 5×103 cells with Celastrol in triplicate in a 96-well plate at 37 ℃. Then adding MTT solution to each well. After a 2 hours incubation at 37 ℃, adding extraction buffer (20% SDS, 50% dimethylformamide) , incubating cells overnight at 37 ℃, and then measuring the optical density at 570 nm using a Tecan plate reader.
Concentrations ~5 μM
Incubation time 2 hours
Animal Experiment
Animal models nude mice bearing C4-2B tumors
Formulation 10% DMSO, 70% Cremophor/ethanol (3:1), and 20% PBS
Dosages 3 mg/kg
Administration Intraperitoneal injection
Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
