Resveratrol

501-36-0 Biological Activity

Description

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.

In Vitro

Resveratrol is one of the numerous polyphenolic compounds found in several vegetal sources In the vast majority of cases, Resveratrol displays inhibitory/activatory effects in the micromolar range, which is potentially attainable pharmacologically, although targets with affinities in the nanomolar range have also been reported. Resveratrol also is a sirtuin activator[1]. MCF-7 cells are plated in DME-F12 medium supplemented with 5% FBS in the presence of increasing concentrations of Resveratrol. Control cells are treated with the same volume of vehicle only (0.1% ethanol). Resveratrol inhibits the growth of MCF-7 cells in a dose-dependent fashion. Addition of 10 μM Resveratrol results in an 82% inhibition of MCF-7 cell growth after 6 days while at 1 μM, only a 10% inhibition is observed. The cells treated with 10 μM Resveratrol have a doubling time of 60 hr whereas control cells doubled every 30 hr. Trypan blue exclusion assay shows that at concentrations of 10 μM or lower, Resveratrol does not affect cell viability (90% viable cells) whereas at 100 μM, only 50% of the cells are viable after 6 days of Resveratrol treatment. Moreover, MCF-7 cells do not undergo apoptosis after incubation with Resveratrol at concentration of 10 μM as determined by ApoAlert Annexin V Apoptosis kit[2].

In Vivo

The average tumor volume is reduced by treatment with Resveratrol at a dose of 50 mg/kg body weight (195.5±124.8 mm3; P<0.05) or 100 mg/kg body weight (81.7±70.5 mm3; P<0.001) compare with the vehicle-treated animals (315±94 mm3). There is a good correlation between the tumor volume and the tumor mass[3].

Cell Assay

To determine the effect of Resveratrol on cell growth, MCF-7 cells are plated in 6-well plates at 105 cells per well in 2 mL of DME-F12 medium supplemented with 5% FBS in the presence or absence of increasing concentrations of Resveratrol. The cell number is measured every 2 days till day 6 with a hemocytometer after detaching the cells with trypsin-EDTA[2].

Animal Admin

Mice[3] Female BALB/c (nu/nu) mice, 6 weeks old, are used. PA-1 cells (1×107 in 200 μL PBS) are injected s.c. on the right hind flank. Tumor volume (length×width×depth×0.52) is measured three times a week. After 10 days of implantation, two groups (n=10) are given Resveratrol (dissolved in 5% ethanol and 25% polyethyleneglycol 400 in distilled water) i.p. at a daily dose of 50 or 100 mg/kg body weight for consecutive 4 weeks, whereas the other group receive the vehicle only. Body weights are recorded everyday. Animals are given bromodeoxyuridine (BrdUrd; 10 mg/kg body weight, i.p.) 2 h before sacrifice. Xenograft tumors are weighed and frozen in liquid nitrogen or fixed in 10% formalin and embedded in paraffin. The BrdUrd-labeled cells in paraffin-embedded tissues are detected employing a monoclonal anti-BrdUrd antibody.
