产品描述 4-Hydroxytamoxifen (ICI 79280) is the active metabolite of Tamoxifen, an estrogen receptor modulator (SERM) with selective and oral potency. 4-Hydroxytamoxifen has antitumor activity and may be used in breast cancer research.
靶点活性 ERR:3.3 nM
体外活性 方法:人子宫内膜腺癌细胞系 HEC-1B 用 4-Hydroxytamoxifen (0.01-100 µM) 处理 3 天,使用 CellTiter 96 AQueous One Solution Cell Proliferation Assay 检测细胞活力。
结果:暴露于更高浓度 (1-100 µM) 的 4-Hydroxytamoxifen 的 HEC-1B 细胞显示出不同浓度之间细胞存活率的显著差异。[1]
方法:ER-阳性乳腺癌症细胞系 MCF-7、T47D 和 BT-474 用 4-Hydroxytamoxifen (0.5-1 µM) 和 sulforaphane (5 µM) 处理 48 h,使用 Western Blot 检测靶点蛋白表达水平。
结果:Sulforaphane 诱导 PARP 切割,其强度取决于细胞系。sulforaphane 和 4-Hydroxytamoxifen 的联合治疗进一步提高了 PARP 的切割。[2]
体内活性 方法:为检测体内抗肿瘤活性,将 Cholesterol (1 mg/kg) 腹腔注射给携带人乳腺癌肿瘤 MCF-7 的 Nu/Nu 小鼠,每天一次,持续二十三天。
结果:4-Hydroxytamoxifen 有效地抑制小鼠的肿瘤生长。[3]
方法:为诱导 Cre 重组酶活性,将 Cholesterol (30-60 mg/kg) 腹腔注射给 Rosa26BEST1-CreERT2 小鼠,每天一次,持续四天。
结果:TdTomato 在两性小鼠的 RPE 中强烈表达。[4]
激酶实验 Cytosol (200 μL) is incubated for 30 min at 4°C with different concentrations of oestradiol, tamoxifen and (4-Hydroxytamoxifen) or dihydroxytamoxifen administered in 10 μL methanol. Control tubes are incubated with 10 μL methanol alone and non-specific binding is determined in a parallel incubation of cytosol (200 μL) with methanol (10 μL) containing DES (5 × 106 M). [2,4,6,7-3H]Oestradiol solution (50 μL) in TED buffer is added to each tube to give a final concentration of 2 × 10-9 M. Incubation is continued for 4 h (4°C) and then 400 μL of a suspension of dextran-coated charcoal (250 mg % Norit A, 2.5 mg % dextran) in TED buffer is added and allowed to stand for 20 min. Tubes are centrifuged at 800 g for 10 min (4°C) and 400 μL samples of the supernatant are added to 10 mL tritium scintillator (6 g butyl PBD, 135 mL toluene, 720 ml dioxane, 100 g naphthalene, 45 mL absolute methanol). Samples are counted for 10 min in a liquid scintillation spectrometer. Counting efficiency is determined by external standardization (35-36 %). Results are represented as a percentage of the specifically bound radioactivity (c.p.m.) in the control tubes[1].
动物实验 4-Hydroxytamoxifen is formulated in sesame oil[3].Animals of each sex are divided into two groups: one group receives 4-Hydroxytamoxifen [6 μg/0.1 mL sesame oil/day, subcutaneously (s.c.) starting at 06.00 h] injections for three consecutive days, while the other group receives an equivalent amount of sesame oil injection for 3 days. Four hours following the third injection, each group is then subdivided into two groups: one receives four cumulative doses of methamphetamine hydrochloride (10 mg/kg, s.c.), and the other receives a comparable volume of saline at 2-h intervals. Bilateral gonadectomy is performed under pentobarbital anesthesia (50 mg/kg, intraperitoneally). Five weeks after surgery, gonadectomized mice of each sex are randomly divided into six groups. Five groups of each sex receive three daily injections of various concentrations of 4-Hydroxytamoxifen (0, 1.5, 3.0, 6.0, and 12.0 μg/0.1 mL sesame oil/day). Four hours following the third injection, mice receive four doses of methamphetamine (MA, 10 mg/kg) at 2-h intervals. The remaining group of each sex receives sesame oil pretreatment for three consecutive days, followed by saline injections, and serves as the control group[3].

TargetMol Calculator 体内实验配液计算器

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。

母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。

体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
