Flavonoids and Polyphenols

<p>Stability Hygroscopic<br>Applications Dihydrogenistein is a derivative of Genistein (G350000), a compound that exhibits specific inhibitory activity against tyrosine kinases,including autophosphorylation of epidermal growth factor receptor kinase.<br>References McLaughlin, J.M., et al.: Cancer. Prevent. Res., 5, 496 (2012); Magiera, S., et al.: J. Pharma. Biomed. Anal., 56, 93 (2011);<br></p>

<p>Applications An anthocyanin responsible for red pigment in fruits and berries. It is an antioxidant, protecting the cell against damage from SOD.<br>References Riihinen, K., et al.: Food Chem., 110, 156 (2008), Khanizadeh, S., et al.: J. Food Comp.

<p>Applications Isoorientin is a flavonoid compound that can be isolated from the passion flower, and several other species of plants. Isoorientin has also shown to exert antioxidant, anti-nociceptive, anti-inflammatory and gastroprotective activities in several studies.<br>References Alves, S.F., et al.: J. Pharma. Rsch., 4, 4621 (2011); Ma, X., et al.: J. Agri. Food. Chem., 60, 10844 (2012); Joubert, E., et al.: J. Agri. Food. Chem., 60, 9171 (2012);<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.
