Flavonoides e Polifenóis

<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 Protected Curcumin (C838500). A natural phenolic compound. Potent anti-tumor agent having anti-inflammatory and anti-oxidant properties. Induces apoptosis in cancer cells and inhibits phorbol ester-induced protein kinase C (PKC) activity. Reported to inhibit production of inflammatory cytokines by peripheral blood monocytes and alveolar macrophages. Potent inhibitor of EGFR tyrosine kinase and IκB kinase. Inhibits inducible nitric oxide synthase (iNOS), cycloxygenase and lipoxygenase. Easily penetrates into the cytoplasm of cells, accumulating in membranous structures such as plasma membrane, endoplasmic reticulum and nuclear envelope.<br>References Srinivasan, et al.: J. Pharm.
