| 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] |

| 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. |
