WebDexamethasone inhibits COX-2 mRNA expression induced by IL-1 in human articular chondrocytes. Dexamethasone suppresses the cyclooxygenase-2 induction by tumor necrosis factor α (TNFα) with an IC50 of 1 nM in MC3T3-E1 cells. Dexamethasone binds to the glucocorticoid receptor and then to the glucocorticoid response element. WebAbstract. Steroidal compounds that are closely related structurally to ecdysone are grouped as ecdysteroids. Ecdysteroids identified in plants are named phytoecdysteroids, and those from animals are sometimes called zooecdysteroids. Among ecdysteroids, ecdysone and 20-hydroxyecdsone (20E) are integral to the growth and reproductive functions in ...

WebMay 25, 2024 · Understanding the structural basis of the selectivity of steroid hydroxylation requires detailed structural and functional investigations on various steroid hydroxylases with different selectivities, such as the bacterial cytochrome P450 enzymes. Here, the crystal structure of the cytochrome P450 CYP106A1 from Priestia megaterium was solved. Dexamethasone is a synthetic pregnane corticosteroid and derivative of cortisol (hydrocortisone) and is also known as 1-dehydro-9α-fluoro-16α-methylhydrocortisone or as 9α-fluoro-11β,17α,21-trihydroxy-16α-methylpregna-1,4-diene-3,20-dione.
