Dienogest
Based on 3 publication(s) in Google Scholar
Dienogest (STS-557) is an orally active and selective progesterone receptor agonist that effectively reduces the gene expression of COX-2, mPGES-1 and aromatase. Dienogest also inhibits the mRNA and protein expression of PGE2 synthase and the activation of NF-κB. Dienogest can be used in studies of endometriosis, menopause and menorrhagia.

Biological Activity
Dienogest (0.01-1 μM; 24 h) inhibits PGE2 production via inhibition of PGE2 synthase gene expressions with the concomitant inhibition of NF-κB activity in a spheroid culture[1].
Dienogest (0.1 μM; 24 h) inhibits aromatase expression gene along with COUP-TFII mRNA expression in a PGE2-independent manner[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
