16b-Hydroxyestradiol

Description

16B-Hydroxyestradiol, which is better known as epiestriol (or 16beta-epiestriol or 16beta-hydroxy-17beta-estriol), belongs to the class of organic compounds known as estrogens and derivatives. These are steroids with a structure containing a 3-hydroxylated estrane. Thus, epiestriol is considered to be a steroid molecule. Formally 16b-hydroxyestradiol is a 3-hydroxy steroid that is 17beta-estradiol substituted by a beta-hydroxy group at position 16. In other words, it has hydroxyl groups at the C3, 16-beta, and 17-beta positions. It is an oxidative metabolite of 17beta-estradiol (PMID: 12865317 ). Epiestriol is found in all vertebrates. Epiestriol is a minor and weak endogenous estrogen. It is the 16beta-epimer of estriol (which is 16alpha-hydroxy-17beta-estradiol). Epiestriol has been used clinically in the treatment of acne. In addition to its estrogenic actions, epiestriol has been found to possess significant anti-inflammatory properties without glycogenic activity or immunosuppressive effects (PMID: 9120824 ).
