产品描述 | Y134 is an estrogen receptor inhibitor that is selective and orally active, exhibiting strong antagonist activity against ERα and Erβ with Ki of 0.09 nM and 11.31 nM, respectively. The selectivity of Y134 for ERα is 121.1 times higher than that for ERβ. Y134 inhibited the proliferation of ER positive human breast cancer cells stimulated by estrogen. |

体外活性 |
Y134 displays robust antagonistic effects on estrogen receptors (ERs) in CV-1 cells co-transfected with plasmids carrying ERα or ERβ along with estrogen-response element-driven luciferase, resulting in a significant decrease in luciferase activity.[1] Treatment with Y134 (0.01 nM-10 μM; 6 d) effectively suppresses the proliferation of ER-expressing breast cancer cells (MCF-7 and T47D) stimulated by estrogen.[1] |
体内活性 | Administration of Y134 (1-3 mg/kg/day; p.o. for 3 days) completely eliminates the estrogen-induced growth of terminal end buds (TEB) in the mammary glands of ovariectomized rats. Y134 exhibits a dose-dependent inhibition of uterine cell proliferation induced by estrogen (E2). [1] |

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。
