产品描述：

5β-Dihydroprogesterone (5β-DHP) is a progesterone receptor agonist and metabolite of progesterone .1,2 It is formed from progesterone by 5β-reductase.2 5β-DHP inhibits spontaneous contractions in isolated rat uterus when used at a concentration of 10 µg/ml, an effect that can be blocked by the progesterone receptor antagonist RU486 but not the GABAA receptor antagonist picrotoxin .1 It is a negative modulator of homooligomeric Ρ1 subunit-containing GABAA receptors, inhibiting GABA-induced currents in X. laevis oocytes expressing these receptors (IC50 = 5.02 µM).3 Plasma levels of 5β-DHP decrease at the onset of spontaneous human labor.4 1.Putnam, C.D., Brann, D.W., Kolbeck, R.C., et al.Inhibition of uterine contractility by progesterone and progesterone metabolites: Mediation by progesterone and gamma amino butyric acidA receptor systemsBiol.
