Tamoxifen citrate

Tamoxifen citrate is a white to off-white powder with no smell. It can dissolve in methanol, ethanol, and acetone to varying degrees and can slightly dissolve in trichloromethane, but it is almost insoluble in water. It can dissolve in glacial acetic acid. When tamoxifen citrate reaches a temperature between 142-148°C, it melts and decomposes at the same time.

개요Tamoxifen is a non-steroidal compound with structural similarities to diethylstilbestrol. Tamoxifen citrate is an estrogen receptor antagonist/partial agonist. Induces oxidative stress and apoptosis in estrogen receptor-negative cancer cell lines. Displays neuroprotective effects in permanent focal ischemia. Inhibits PKC. Potent agonist at GPR30 (membrane estrogen receptor). Clinically useful breast cancer agent.

용도Tamoxifen Citrate 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.

일반 설명Tamoxifen, 2-[4-(1,2-diphenyl-1-butenyl)phenoxy]-N,N-dimethylethanamine(Nolvadex), is a triphenylethylene SERM used to treatearly and advanced breast carcinoma in postmenopausalwomen. Tamoxifen is used as adjuvant treatment for breastcancer in women following mastectomy and breast irradiation.It reduces the occurrence of contralateral breast cancerin patients receiving adjuvant tamoxifen therapy. It is alsoeffective in the treatment of metastatic breast cancer in bothwomen and men. In premenopausal women with metastaticbreast cancer, tamoxifen is an alternative to oophorectomyor ovarian irradiation. Tamoxifen can be used preventativelyto reduce the incidence of breast cancer in women athigh risk. Antiestrogenic and estrogenic side effects caninclude hot flashes, nausea, vomiting, platelet reduction,and (in patients with bone metastases) hypercalcemia. Likeall triphenylethylene derivatives, it should be protectedfrom light.
