<p>Applications RIBOFLAVINE TETRABUTYRATE (cas# 752-56-7) is a useful research chemical.<br></p>

<p>Applications Pinocembrin is a flavanoid with antioxidant activity found in damiana, honey, and propolis. Recent studies show that Pinocembrin maybe be a therapeutic option in reducing cerebral ischemia/reperfusion injury as a result of its anti-oxidative and anti-apoptotic effects. Pinocembrin displayed neuroprotective effects in glutamate injury model partly by inhibiting p53 expression causing a lower Bax-Bcl-2 ratio and by inhibiting the release of cytochrome c.<br>References Zhao, J. et al.: J.

<p>Applications Silybin B is the 2R, 3R, 7‘S, 8‘S isomer of Silybin (S465850); a natural occurring flavolignan that exerts anti-inflammatory and anti-fibrogenic effects on human hepatic stellate cells.<br>References Lee, D.Y.W, et al.: J.

<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.
