4-Hydroxyestrone-d4
Based on 1 Customer Validation
4-Hydroxyestrone (4-OHE1)-d4 is the deuterium labeled 4-Hydroxyestrone (HY-W009300). 4-Hydroxyestrone is a brain-penetrant estrogen metabolite. 4-Hydroxyestrone shows neuroprotective effects involving increased cytoplasmic localization of p53 resulting from SIRT1-mediated p53 deacetylation. 4-Hydroxyestrone relies on PDI to mediate its protective effect against chemically induced ferroptosis in estrogen receptor-negative cancer cells. 4-Hydroxyestrone inhibits lipid peroxidation and lipid-ROS accumulation. 4-Hydroxyestrone blocks preovulatory luteinizing hormone surges in Rattus norvegicus. 4-Hydroxyestrone can be used for the researches of neurodegeneration, breast cancer and endocrine disease.
