| Chemical Properties | WHITE TO PALE YELLOW CRYSTALS OR CRYST. POWDER | | Uses | Antioxidant agent-15 (Compound 4) is a potent antioxidant inhibition activity, with the IC50 of 15.44 nM. Antioxidant agent-15 inhibits tumor cell growth in Hela, Hep G2 and Caco-2 cells, with the IC50 of 395.26, 400.4 and 24.6 nM, respectively[1]. | | Purification Methods | Dissolve hydroxypixyl in AcOH and add H2O whereby it separates as colourless prisms. It is slightly soluble in CHCl3, soluble in *C6H6 but insoluble in pet ether. It sublimes on heating. UV in H2SO4: 450nm max ( 5620) and 370nm ( 24,900) and the HClO4 salt in CHCl3 has 450 ( 404) and 375nm ( 2420). max [Sharp J Chem Soc 2558 1958, Bünzly & Decker Chem Ber 37 2983 1904, Chattopadhyaya & Reece J Chem Soc, Chem Commun 639 1978, Gomberg & Cone Justus Liebigs Ann Chem 370 142 1909, Beilstein 17 I 80, 17 II 161, 17 III/IV 1704, 17/4 V 675.] | | References | [1] Abualhasan M, et al.
