<p>Applications Lobetyolin is a natural phenolic glycoside found in herbal remedies used in Chinese and Korean medicine. Potential treatment for diabetic complications.<br>References Jang, D. et al.: Arch. Pharm. Res., 33, 875 (2010); Koike, Y. et al.: J. Nat. Med., 64, 245 (2010);<br></p>

<p>Applications Labelled Ferulic acid (4-hydroxy-3-methoxycinnamic acid or, in IUPAC nomenclature, 3-(4-hydroxy-3-methoxy-phenyl)prop-2-enoic acid) which is a highly abundant phenolic phytochemical which is present in plant cell walls. It may have significant health benefits through its antioxidant and anti-cancer activity, and may also serve as a precursor in the manufacturing of useful aromatic compounds. Used as an antioxidant.<br>References Smart, M.G., et al.: Aust. J. Plant Physiol., 6, 485 (1979), Chen, C., et al.: J. Food Lipids, 2, 35,1995, Benzie, I., et al.: Anal.

<p>Applications A natural phenolic compound. Potent anti-tumor agent having anti-inflammatory and antioxidant 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.Curcumin is currently being examined as a possible therapeutic for the treatment of Alzheimers disease. Neuroprotective. Dyes and metabolites.<br>References Srinivasan, et al.: J. Pharm.
