Descrição geral

Tamoxifen is a selective estrogen response modifier (SERM), protein kinase C inhibitor and anti-angiogenetic factor. Tamoxifen is a prodrug that is metabolized to active metabolites 4-hydroxytamoxifen (4-OHT) and endoxifen by cytochrome P450 isoforms CYP2D6 and CYP3A4. In breast cancer, the gene repressor activity of tamoxifen against ERBB2 is dependent upon PAX2. Blocks estradiol-stimulated VEGF production in breast tumor cells.

Aplicação

Tamoxifen has been used to facilitate the recombination of ect2flox allele in mouse organs91. It has also been used to study its effect on lipopolysaccharide (LPS)-induced microglial activation92.

Ações bioquímicas/fisiológicas

Protein kinase C inhibitor. Induces apoptosis in human malignant glioma cell lines. Tamoxifen and its metabolite 4-hydroxytamoxifen are selective estrogen response modifiers (SERMs) that act as estrogen antagonists in mammary gland. Blocks estradiol-stimulated VEGF production in breast tumor cells.

Nota de preparo

Tamoxifen is soluble in chloroform at 50 mg/ml and yields a clear, colorless to faint yellow solution. It is also soluble in methanol, ethanol, 2-propanol and propylene glycol. Stock solutions of tamoxifen can also be prepared in DMSO at 10 mM. However, it is practically insoluble in water (solubility is <0.01%, 20° C). Solutions are sensitive to UV light, and DMSO solutions are stable when stored at -20° C in the dark.

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product. 

  5. What is the solubility of tamoxifen, Product No. T5648?

    Tamoxifen is tested for solubility in chloroform at a concentration of 50mg/mL.  This yields a colorless to faint yellow solution.  Tamoxifen is practically insoluble in water.  It has been reported to be soluble in methanol, ethanol, 2-propanol and propylene glycol.  This product is also reported to be soluble in DMSO at 10mM concentration.  Reference for DMSO solubility: Wong, K.R., et al., Am. J. Physiol. Heart Circ. Physiol., 277, H1403-H1409 (1999).  Please also see the product information sheet (under Documents, above) for more information on the solubility of this product.

  6. What is the stability of tamoxifen (e.g., Product No. T5648) once in solution?

    Solutions of tamoxifen are sensitive to UV light. According to C.A. O'Brian et al., [Cancer Res. 45, 2462 (1985)], tamoxifen when dissolved in DMSO can be stored at -20°C in the dark. We generally recommend making the solution fresh right before each use.

  7. How do I find the expiration date of the bottle of Product No T5648, Tamoxifen, in my possession?

    According to Sigma Quality Control Data, T5648 (tamoxifen) should be stable for at least two years if stored dessicated at 2-8°C in the dark.  However, there is not an established expiration or retest date for Tamoxifen.  This product is guaranteed for 1 year from shipment, if stored correctly and unopened.
