Flavonoids and Polyphenols

<p>Applications Cannflavin B is a prenylated flavone which can be isolated from the cannabinoid free ethanolic extract of Cannabis sativa L.<br>References Barrett, M. L., Experientia, 42, 452-3, (1986)<br></p>

<p>Applications Exhibits specific inhibitory activity against tyrosine kinases,including autophosphorylation of epidermal growth factor receptor kinase (IC50 - 2.6uM). Also inhibits other protein kinases through competitive inhibition of ATP. Inhibits tumor cell proliferation and induces tumor cell differentiation. Produces cell-cycle arrest and apoptosis in Jurat T-leukemia cells. However, it prevents anti-CD3 monoclonal antibody-induced thymic apoptosis. Genistein also inhibits topoisomerase II activity in vitro. Genistein has also been shown to inhibit the action of GABA on recombinant GABAA receptors2. uv(max)ethanol: 262.5 nm (e= 138). moderately sol. in hot alcohol<br>References Akiyama, T., et al.: J.

<p>Applications Allyl Bromide is used as a reagent in the synthesis of Resveratrol derivatives. Resveratrol (R150000) is a minor constituent of wine, correlated with serum lipid reduction and inhibition of platelet aggregation. Resveratrol is a specific inhibitor of COX-1, and it also inhibits the hydroperoxidase activity of COX-1. It has been shown to inhibit events associated with tumor initiation, promotion and progression.<br> E0<br>References Powell, R.G., et al.: Phytochemistry, 35, 335 (1994), Jeandet, P., et al.: J.
