Resveratrol is a selective human cytochrome P450 1A1 inhibitor. Resveratrol slightly inhibited ethoxyresorufin O-deethylation (EROD) activity in human liver microsomes with an IC50 of 1.1 mM.
|Cell lines||CNE-1 and CNE-2Z cells|
|Preparation method||Cell proliferation assay
The effect of resveratrol on the cell growth of CNE-1 and CNE-2Z cells was examined using the MTT assay. Cancer cells were plated in 96-well plates at 104 cells/well. Following pretreatment with different concentrations of resveratrol for 24 or 48 h, viable cells were determined using the MTT Assay kit (Chemicon, Temecula, CA, USA) according to the manufacturer’s protocol. At indicated time-points, 20 μl of MTT solution (5 mg/ml in PBS) were added into each well and incubated for 4 h. Then, 100 μl of DMSO was added to dissolve the crystals. The plate was then left to stand for 10 min at room temperature and the corresponding absorbance was measured at 490 nm. Each experiment was performed in triplicate.
|Concentrations||0, 10, 25, 50 and 100 μM|
|Incubation time||24 or 48 h|
|Animal models||female nude mice bearing CNE-2Z tumour xenograft model|
|Formulation||10% DMSO in PBS|
|Dosages||20 mg/kg once a day for 3 weeks|
|Body Surface Area (m2)||0.007||0.025||0.15||0.05||0.02||0.5|
|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.
|Solubility||DMSO 40 mg/mL|
Resveratrol inhibits human nasopharyngeal carcinoma cell growth via blocking pAkt/p70S6K signaling pathways.
