Description

Epipregnanolone is a neurosteroid and an active metabolite of the steroid hormone pregnenolone .1 It is enzymatically formed from pregnenolone via the intermediates progesterone and 5β-dihydroprogesterone in the placenta.2 Epipregnanolone inhibits spontaneous contractions in myometrial strips isolated from at-term pregnant women (IC50 = 156 ?M).3 Epipregnanolone (10 and 20 mg/kg) decreases operant alcohol self-administration in rats.4 Maternal plasma levels of epipregnanolone increase over the duration of pregnancy.
