CIS-TRIMETHOXY STILBENE

Description

Resveratrol is a potent antioxidant found in grapes and red wine that also has anti-proliferative, anti-neoplastic and anti-angiogenic activities. In addition, resveratrol activates sirtuins and, in yeast, extends lifespan. cis-trismethoxy Resveratrol is a potent anti-mitotic drug that is 100-fold more active than resveratrol at inhibiting the growth of human colon cancer Caco-2 cells. It inhibits tubulin polymerization in a dose-dependent manner (IC₅₀ = 4 μM) and inhibits enzymes involved in the synthesis of the polyamines, putrescine, and spermidine. trans-trismethoxy Resveratrol has superior pharmacokinetic characteristics when compared with resveratrol, including greater plasma exposure, longer elimination half-life, and lower clearance.

The Uses of CIS-TRIMETHOXY STILBENE

cis-trismethoxy Resveratrol is a potent antioxidant found in grapes and red wine. Also, it is a resveratrol analog with increased antiproliferative activity towards a number of cancer cell lines.

What are the applications of Application

cis-trismethoxy Resveratrol is a potent antioxidant found in grapes and red wine

in vitro

cis-trismethoxy resveratrol at 0.3 microm could exert a 80% growth inhibition of human colon cancer caco-2 cells and arrest growth completely at 0.4 microm. the cis conformation of cis-trismethoxy resveratrol was also 100-fold more potent than the trans isomer. cis-trismethoxy resveratrol was able to cause cell cycle arrest at the g2/m phase transition and inhibit tubulin polymerization dose-dependently, leading to the depletion of the polyamines, putrescine and spermidine. in addition, cis-trismethoxy resveratrol inhibited partially colchicine binding to its binding site on tubulin [1].

in vivo

previous study found that from the angle of pharmacokinetics, cis-trismethoxy resveratrol appeared to be a superior analog of resveratrol since it was orally available and showed greater plasma exposure, longer elimination half-life and lower clearance. due to the superior pharmacokinetic characteristics of cis-trismethoxy resveratrol had, its potentials as a preventive or therapeutic agent in resveratrol-effective diseases would be considered [2].
