Flavonoids and Polyphenols

<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 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>References Powell, R.G., et al.: Phytochemistry, 35, 335 (1994), Jeandet, P., et al.: J.

<p>Applications Bisdemethoxycurcumin is one of the three major forms of curcuminoids found in the rhizomes of turmeric. Bisdemethoxycurcumin displays antioxidant, anti-inflammatory as well as chemotherapeutic activity. Bisdemethoxycurcumin acts as an inhibitor of human pancreatic α-amylase, a target for type-2 diabetes .<br>References Ponnusamy, S. et al.: Food Chem., 135, 2638 (2012); Hung, C.-M. et al.: J. Agric.
