说明

一般說明

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.

應用

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).

生化／生理作用

蛋白激酶 C 抑制剂。诱发人类恶性神经胶质瘤细胞系的细胞凋亡。他莫昔芬及其代谢产物 4-羟基他莫昔芬是选择性雌激素反应调节剂 (SERM)，在乳腺中用作雌激素拮抗剂。阻止乳腺肿瘤细胞中雌二醇刺激的 VEGF 的产生。

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.

準備報告

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