4-hydroxy Estrone is a metabolite of the endogenous estrogen estrone .1 It is formed from estrone primarily by the cytochrome P450 (CYP) isoforms CYP1B1, CYP1A2, and CYP1A1. 4-hydroxy Estrone (5 µM) induces nuclear translocation of phosphorylated p53 and is protective against glutamate-induced oxidative death in HT22 hippocampal neuronal cells.2 It reduces neurodegeneration induced by kainic acid in the rat hippocampus and improves working memory in the Y-maze in rats when administered at a dose of 10 µg/animal. 4-hydroxy Estrone also inhibits proliferation of MCF-7 and MDA-MB-231 breast cancer cells with IC50 values of 30 and 38 µM, respectively.3

General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |

Working concentration: mg/ml;
Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )
Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.
Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.
Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
