It is a weak antiestrogen but a ten-fold more potent inhibitor of protein kinase C (PKC) than tamoxifen. It also potently regulates ceramide metabolism in human AML cells, limiting ceramide glycosylation, hydrolysis, and sphingosine phosphorylation\u003csup\u003e[1][2][3]\u003c\/sup\u003e. It is supplied as a white to off-white solid (C25H27NO, MW 357.50) at 99.59% purity.\u003c\/p\u003e\n\u003ch2\u003ePhysical \u0026amp; Chemical Properties\u003c\/h2\u003e\n\u003ctable class=\"bhp-spec-table\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eCAS Number\u003c\/th\u003e\n\u003ctd\u003e31750-48-8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMolecular Formula\u003c\/th\u003e\n\u003ctd\u003eC25H27NO\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMolecular Weight\u003c\/th\u003e\n\u003ctd\u003e357.50 g\/mol\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePurity\u003c\/th\u003e\n\u003ctd\u003e99.59%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAppearance\u003c\/th\u003e\n\u003ctd\u003eSolid\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eColor\u003c\/th\u003e\n\u003ctd\u003eWhite to off-white\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSMILES\u003c\/th\u003e\n\u003ctd\u003eCC\/C(C1=CC=CC=C1)=C(C2=CC=C(OCCNC)C=C2)\\C3=CC=CC=C3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTarget\u003c\/th\u003e\n\u003ctd\u003ePKC, Estrogen Receptor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSignaling Pathway\u003c\/th\u003e\n\u003ctd\u003eEpigenetics; TGF-beta\/Smad; Vitamin D Related\/Nuclear Receptor; Metabolic Enzyme\/Protease\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSolubility\u003c\/th\u003e\n\u003ctd\u003eIn Vitro: DMSO: 11.4 mg\/mL (31.89 mM; Requires sonication; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStorage\u003c\/th\u003e\n\u003ctd\u003ePowder: -20°C, 3 years; 4°C, 2 years.
