Chemical compound
5α-Dihydroprogesterone (5α-DHP ), also known as 5α-pregnan-3,20-dione , is an endogenous progestogen and neurosteroid that is synthesized from progesterone .[ 1] [ 2] It is also an intermediate in the synthesis of allopregnanolone and isopregnanolone from progesterone. 5α-DHP is an agonist of the progesterone receptor and a positive allosteric modulator of the GABAA receptor (albeit with an affinity for this receptor that is regarded as relatively low (in comparison to 3α-hydroxylated progesterone metabolites such as allopregnanolone and pregnanolone )).[ 1] [ 2] [ 3] [ 4] It has also been found to act as a negative allosteric modulator of the GABAA -rho receptor .[ 5] In addition, it is a weak agonist of the pregnane X receptor (PXR) (EC50 >10,000 µM)), with approximately six-fold lower potency relative to its 5β-isomer, 5β-dihydroprogesterone .[ 6]
