Tamoxifen試劑

Tamoxifen (ICI 47699) 是一種口服有效的，選擇性雌激素受體 (estrogen receptor) 調(diào)節(jié)劑 (SERM)，可阻斷乳腺細(xì)胞中的雌激素作用，并可激活其他細(xì)胞，如骨骼，肝臟和子宮細(xì)胞中的雌激素活性。Tamoxifen 是一種有效的 Hsp90 激活劑，可增強(qiáng) Hsp90 分子伴侶 ATPase 的活性。Tamoxifen 還可以有效抑制傳染性 EBOV Zaire 和 Marburg (MARV)，IC₅₀ 分別為 0.1 µM 和 1.8 µM。Tamoxifen 可以激活自噬 (autophagy)，誘導(dǎo)凋亡 (apoptosis)。Tamoxifen 還可以誘導(dǎo) CreER(T2) 轉(zhuǎn)基因小鼠的基因敲除。

Tamoxifen試劑 生物活性

Tamoxifen (ICI 47699) is an orally active, selective estrogen receptor modulator (SERM) which blocks estrogen action in breast cells and can activate estrogen activity in other cells, such as bone, liver, and uterine cells^[1]^[2]^[3]. Tamoxifen is a potent Hsp90 activator and enhances the Hsp90 molecular chaperone ATPase activity. Tamoxifen also potent inhibits infectious EBOV Zaire and Marburg (MARV) with IC₅₀ of 0.1 µM and 1.8 µM, respectively^[5]. Tamoxifen activates autophagy and induces apoptosis^[4]. Tamoxifen also can induce gene knockout of CreER(T2) transgenic mouse^[6].

體外研究
(In Vitro)

Tamoxifen (ICI 47699) shows strong inhibition of MCF-7 cells (EC₅₀=1.41 μM) and to a lesser extent the T47D cells (EC₅₀=2.5 μM) but does not affect the MDA-MB-231 cells^[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

體內(nèi)研究
(In Vivo)

Injection of pre-mutant mice with Tamoxifen (75 mg/kg; injected for 5 days at 6 weeks of age) results in the excision of the floxed exon and, thus, in a gene knockout^[3].
