17alpha-Estradiol

Description

17alpha-Estradiol (also known as 17alpha-E2, 17-epiestradiol) 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. 17alpha-Estradiol is also classified as an estradiol. Specifically, estradiols are characterized by an estra-1,3,5(10)-triene substituted by hydroxy groups at positions 3 and 17. 17alpha-Estradiol is considered as a 17alpha-hydroxy steroid and a 3-hydroxy steroid. 17alpha-Estradiol is a weak endogenous steroidal estrogen that is related to 17beta-estradiol. 17beta-estradiol is better known simply as estradiol or E2 (PMID: 16728493 ). Therefore, 17alpha-Estradiol is the C17 alpha epimer of 17beta-estradiol (PMID: 16728493 ). 17alpha-Estradiol is found in all vertebrates. It has approximately 100-fold lower estrogenic potency than 17beta-estradiol. 17alpha-estradiol is a non-feminizing estrogen with significantly reduced binding affinity for the classic estrogen receptors ERalpha and ERbeta. Although 17alpha-estradiol is far weaker than 17beta-estradiol as an agonist of the nuclear estrogen receptors, it has been found to bind to and activate the brain-expressed ER-X with a greater potency than that of 17beta-estradiol. 17alpha-Estradiol is a potent 5-alpha reductase inhibitor that has been shown to improve metabolic function, enhance insulin sensitivity, and reduce fat and inflammation in older lab animals without causing feminization (PMID: 26809497 ). It has also been shown that 17alpha-Estradiol also increases AMPK levels and reduced mTOR activity in visceral adipose tissue (PMID: 26809497 ).
