Homogeneous suspension	CMC-NA	≥5mg/ml	Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
Clear solution	10% DMSO 1 40% PEG 300 2 5%Tween80 3 45% water この製剤はselleckのラボで検証済みです。上記の溶解方法がご要望を満たさない場合、selleckの営業担当までお問い合わせ頂ければ、個別の試験を行います。	5.000mg/ml (12.90mM)	Taking the 1 mL working solution as an example, add 100 μL of 50 mg/ml clear DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify it; then continue adding Dilute 450 μL ddH2O to 1 mL. The mixed solution should be used immediately for optimal results.
Clear solution	10% DMSO 1 90% corn oil この製剤はselleckのラボで検証済みです。上記の溶解方法がご要望を満たさない場合、selleckの営業担当までお問い合わせ頂ければ、個別の試験を行います。	2.500mg/ml (6.45mM)	Taking the 1 mL working solution as an example, add 100 μL of 25 mg/ml clear DMSO stock solution to 900 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明	(Z)-4-Hydroxytamoxifen ((Z)-4-OHT, trans-4-Hydroxytamoxifen, 4-Monohydroxytamoxifen) is a selective modulator of estrogen receptor (SERM) with IC50 of 3.3 nM for the [³H]oestradiol binding to oestrogen receptor.
in vitro	This compound is a partial estrogen that binds to estrogen receptors with relative binding affinity (RBA) of 2.9 and blocks the growth of the MCF-7 human mammary tumor cell line in vitro.^[2]
in vivo	(Z)-4-Hydroxytamoxifen is a partial estrogen with antiestrogenic properties, and the cis isomer is less potent than the trans isomer.^[3] This compound inhibits estradiol benzoate action and reduces the uterine growth rate in vivo.^[2]

細胞アッセイ	細胞株	MCF-7 cells
	濃度	0.1 nM - 10 μM
	反応時間	50 min
	実験の流れ	MCF-7 cells are incubated at 37℃ for 50 min with 1 nM [³H]estradiol in the absence or presence of increasing amounts (0.1 nM - 10 μM) of (Z)-4-Hydroxytamoxifen or unlabeled estradiol (control). Bound compounds are then extracted with ethanol, and the amounts of estrogen receptor bound [³H]estradiol are measured.
