In vitro activity: Resveratrol inhibits the activity of Cyclooxygenase and lipooxygenase, PKCs and p56lck, ERK1, JNK1, p38, IKK β, Src, STAT3, Ribonucleotide Reductase, DNA polymerases α and δ, PKD, PKC α, Quinone reductase 2, and Aromatase with IC50 of from 0.035-60 μM. Resveratrol is also an activator of Adenylyl cyclase and AMPK with EC50 of 0.8 μM and 50 μM, respectively. The roles of Resveratrol as inhibitor or activator enable its effects on decreasing cell inflammatory associated behaviors, growth inhibition and induction of apoptosis in cancer cells, reversal of endothelin-1 stimulated cell responses, inhibition of phorbol ester-induced expression of COX-2, inhibition of DNA synthesis in cell, resistance to menadione-induced cell death, and improvement of cell mitochondrial function and glucose/lipid metabolism. Resveratrol is also an activator of sirtuins. Resveratrol lowers the Michaelis constant of SIRT1 for both the acetylated substrate and NAD+, and increases cell survival by stimulating SIRT1-dependent deacetylation of p53. In yeast, Resveratrol mimics calorie restriction by stimulating Sir2, increasing DNA stability and extending lifespan. Resveratrol is effective at protecting isolated rat hearts against ischemia/reperfusion injury via its antioxidant activity, with improved recovery of developed pressure and aortic flow, reduction of malondialdehyde concentrations and reduction of infarct size.

Kinase Assay: Resveratrol (SRT 501), a natural polyphenol that possesses anti-oxidant, anti-inflammatory, cardioprotective, and anti-cancer properties. It has a wide spectrum of targets including mTOR, JAK, β-amyloid. Resveratrol also is a sirtuin activator.

Cell Assay: Cells (Human breast cancer cell MCF-7) are plated in flat-bottomed, 96-well microtiter plates (4000 cells/6.4-mm-diameter well). After 12–24 hr, cells are treated with DMSO (0.1–0.3%) or increasing doses of Resveratrol. After 48 h of treatment, cells are treated with 10μL of MTT reagent for 4 hr at 37 ℃ and then treated with 100 μL of solubilization solution at 37 ℃ overnight. The quantity of formazan product is measured using a spectrophotometric microtiter plate reader at 570 nm wavelength.
