Background

Epiallopregnanolone (CAS 567-01-1) is an endogenous neurosteroid metabolite derived from progesterone, structurally characterized as the 3β-isomer of allopregnanolone. Epiallopregnanolone functions mainly as a competitive antagonist at neurosteroid binding sites on GABA_A receptors, ligand-gated chloride channels essential for neuronal inhibition. In vitro, it selectively inhibits allopregnanolone-induced chloride ion flux and antagonizes allopregnanolone and ethanol-mediated suppression of hippocampal CA1 population spikes. In vivo experiments indicate epiallopregnanolone reduces ethanol discrimination behavior in trained rats. Its selective GABA receptor antagonism supports utility in neuroactive steroid and ethanol interaction research.
