Beschreibung

General description

Tamoxifen (TAM) an antimicrobial agent is also a selective estrogen response modifier (SERM) that is used to prevent and treat breast cancer. It was first introduced by AstraZeneca as effective therapeutic and preventive agent against estrogen-positive breast cancer. As an antibiotic, TAM has shown a direct inhibitory action on the growth of Staphylococcus aureus, methicillin-resistant S. aureus (MRSA) strains, and M. tuberculosis.1 It is metabolized to active metabolites 4-hydroxytamoxifen (4-OHT) and endoxifen by cytochrome P450 isoforms CYP2D6 and CYP3A4. TAM is also a protein kinase C inhibitor and an anti-angiogenetic factor.

Application

Contribution of metabolic effects of TAM in increasing drug resistance was studied in MCF-7 and MCF7-TAM cell lines. 4-hydroxytamoxifen was used to examine calcium influx in human-induced pluripotent stem cell-derived cardiomyocytes (iPSC-CMs) modeled on Duchenne Muscular Dystrophy (DMD).

Biochem/physiol Actions

Proteinkinase C-Inhibitor. Induziert Apoptose in menschlichen malignen Gliomzelllinien. Tamoxifen und sein Metabolit 4-Hydroxytamoxifen sind selektive Östrogenrezeptormodulatoren (SERM), die als Östrogen-Antagonisten in Brustdrüsen wirken. Hemmt die Estradiol-stimulierte VEGF-Produktion in Brustkrebszellen.

Östrogen-Antagonist in der Brustdrüse. Hemmt die Östradiol-stimulierte VEGF-Produktion in Brustkrebszellen. Proteinkinase C-Inhibitor.

Active metabolites of TAM act as estrogen antagonists inmammary glands and block VEGF production in breast cancer cells. TAM is known toinhibit mitochondrial function, causing increased glycolysis and lactateproduction. 4-hydroxytamoxifen treatment of iPSC-CMs increased cellsurvival, decreased beating rate and increased beating velocity.

As an antibiotic, TAM increases membrane permeabilityand is active against Gram-positive and Gram- negative bacterial strains. It actsas both bactericidal and bacteriostatic agent.

Preparation Note

Tamoxifen is soluble in Acetone at 1gr/ 30 ml and yields a clear, colorless to faint yellow solution. Solution is sensitive to UV light.
