Ethinylestradiol CAS# 57-63-6

Description of Ethinylestradiol

eed, also sometimes written as 17α-ethinyl estradiol, ethinylestradiol, ethynyl estradiol, or ethinyl œstradiol, is a derivative of 17β-estradiol (E2), the major endogenous estrogen in humans. EE2 is an orally bioactive estrogen used in many formulations of combined oral contraceptive pills and is one of the most commonly used medications for this purpose.
Transdermal ethinyl estradiol carries a greater risk of clot formation and venous thromboembolism than naturally occurring 17β-estradiol, which some have theorized to be related to different amounts of hepatic metabolism after absorption. The same contraindications and precautions apply for EE2 as with other estrogen medications.

In two cultured rat hepatocytesandHepG2 cells, EthinylEstradiol increased respiratory chain activity.eed is a strong promoter of liver cancer formation. In female rat liver, EthinylEstradiol increased the transcriptional levels of genes encoded by the nuclear and mitochondrial genomes and respiratory chain activity;
