Piceatannol (3,3′,4,5′-tetrahydroxy-trans-stilbene; PIC) is a naturally occurring stilbene present in diverse plant sources. Piceatannol is a hydroxylated analog of resveratrol and produced from resveratrol by microsomal cytochrome P450 1A11/2 and 1B1 activities. Like resveratrol, Piceatannol has a broad spectrum of health beneficial effects, many of which are attributable to its antioxidative and anti-inflammatory activities. Piceatannol exerts anticarcinogenic effects by targeting specific proteins involved in regulating cancer cell proliferation, survival/death, invasion, metastasis, angiogenesis, etc. in the tumor microenvironment. Piceatannol also has other health promoting and disease preventing functions, such as anti-obese, antidiabetic, neuroprotective, cardioprotective, anti-allergic, anti-aging properties. A comprehensive review of PIC concludes that the compound has the health promoting and disease preventive potential. However, low water-solubility and bioavailability of PIC limit its pharmaceutical application and also use in functional foods. In this context, it is noticeable that beta-cyclodextrin was found to improve the bioavailability, the solubility and the stability of Piceatannol.

The pharmacokinetics of Piceatannol were investigated in male Sprague-Dawley rats after single intravenous doses of 10 mg/kg body weight.

Intravenous
The 96-hole culture plates was used to seed WM266-4 and A2058 cells with 1 x 10 cells/well, and the plate was placed in incubation box at 37 °C with 5% CO2. The cells were treated with different concentrations of piceatannol and after 24-h culture, MTT assay (Gibco) was performed to determine the cell apoptosis. The culture media were placed and 20 μl MTT assay (5 mg/ml) was added to each well prior to 4 h incubation. 150 μl DMSO were added to dissolve the formazan crystals. After 10 min oscillation, the optical density (OD) values were measured with a microplate reader (Beckmann Coulters) at 490 nm. Cell viability was presented as a percent of MTT reduction in the treated cells versus the controls (cells incubated in serumfree DMEM without extracts).
