产品描述	4′-Bromoflavone is a highly effective inducer of phase II detoxification enzymes and has been identified as a potent agent in cancer chemoprevention.
体外活性	4′-Bromoflavone significantly induces quinone reductase (QR) activity in cultured murine hepatoma 1c1c7 cells (concentration to double activity: 10 nM) and effectively induces the α- and mu-isoforms of glutathione S-transferase in cultured H4IIE rat hepatoma cells with no observed toxicity[1]. 4′-Bromoflavone is a potent inhibitor of cytochrome P4501A1-mediated ethoxyresorufin-O-deethylase activity, with an IC 50 of 0.86 μM. In HepG2 or MCF-7 cells, 4′-Bromoflavone significantly reduces the covalent binding of metabolically activated benzo[a]pyrene to cellular DNA[1].
体内活性	In short-term dietary studies, 4′-Bromoflavone is also shown to increase QR activity and glutathione levels in rat liver, mammary gland, colon, stomach, and lung in a dose-dependent manner. In studies conducted with female Sprague Dawley rats ,4′-Bromoflavone significantly increases QR activity (phase II enzyme)[1]. In DMBA-treated female Sprague Dawley rats. Dietary administration of 4′-Bromoflavone (2000 and 4000 mg/kg of diet, from 1 week before to 1 week after DMBA) significantly inhibits the incidence and multiplicity of mammary tumors and greatly increases tumor latency[1].

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。
