Common Name17alpha,20alpha-Dihydroxypregn-4-en-3-one
Description17 Alpha,20alpha-Dihydroxypregn-4-en-3-one, also known as 17,20 alpha-OHP or 20alpha-dihydroxyprogesterone, is a steroid hormone that is elevated in late pregnancy. In particular, the concentration of plasma 17,20 alpha-OHP is significantly increased during the third trimester of pregnancy, and the increment continues to increase through labour and delivery (PMID:6874891 ). 17,20 Alpha-OHP is known to be a substrate for the enzyme 20alpha-hydroxysteroid dehydrogenase or 20alpha-HSD (EC 1.1.1.149). This enzyme catalyzes the following chemical reaction: 17Alpha,20alpha-dihydroxypregn-4-en-3-one + NAD(P)+ = 17alpha-hydroxyprogesterone + NAD(P)H + H+. This enzyme is actively involved in the control of progesterone homeostasis in the pregnancy of mammals. While 20alpha-HSD expression and activity is downregulated in the corpus luteum of pregnancy, 24 hours prior to parturition, ovarian 20alpha-HSD activity is acutely stimulated. 17,20 Alpha-OHP is a biologically weaker progestin. Progestin facilitates estrogen induction of the preovulatory luteinizing hormone (LH) surge. It is known that 17,20 alpha-OHP is increased at midcycle but its importance in regulating LH has not been studied. However, periovulatory levels of 17,20 alpha-OHP do not play a role in modulating the estrogen-induced bioactive LH surge (PMID:2245841 ).
