Tetrahidrodeoksikortikosteron
Tetrahidrodeoksikortikosteron (skraćeno THDOC; 3α,21-dihidroksi-5α-pregnan-20-on), koji se takođe naziva alotetrahidrokortikosteron, je endogeni neurosteroid.[1] Sintetiše se iz nadbubrežnog hormona deoksikortikosterona dejstvom dva enzima, 5α-reduktaze tipa I i 3α-hidroksisteroid dehidrogenaze.[2] THDOC je snažan pozitivni alosterični modulator GABAA receptora i ima sedativno, anksiolitičko i antikonvulzivno dejstvo.[3][4][5] Promene u normalnom nivou ovog steroida, posebno tokom trudnoće i menstruacije, mogu biti uključene u neke vrste epilepsije (katamenijalna epilepsija) i predmenstrualni sindrom,[6] kao i stres, anksioznost i depresiju.[7][8][9][10][11]
