Flavonoids and Polyphenols

<p>Nordalbergin, a coumarin isolated from the bark of Dalbergia sissoo, can significantly induce the differentiation of HL-60 cells.</p>

<p>Applications Khellin is a compound present in the kella or picktooth fruit, used as a muscle relaxant.<br>References Shinde, P. et al.: Indian J. Nat. Prod. Res., 5, 40 (2014); Sztiller-Sikorska, M. et al.:<br></p>

<p>Applications trans-Piceatannol-d3 is an isotope labelled compound of trans-Piceatannol (P436300), which is human metabolite of Resveratrol (R150000).<br>References Athar, M., et al.: Toxicol.

<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 2,4,5-Trichlorophenol-d2 is the labelled analogue of 2,4,5-Trichlorophenol (T774145), which is used as a broad range pesticide against insects, fungi, vegetation and bacteria. It has become a common environmental contaminant and probable human carcinogen.<br> Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package<br>References Amer, S. et al.: Cytologia, 39, 633 (1974); Xu, X. wt l.: Occup.
