生物活性：3α,21-Dihydroxy-5α-pregnan-20-one-d₃ 是一种氘代标记的 3α,21-Dihydroxy-5α-pregnan-20-one。3α,21-Dihydroxy-5α-pregnan-20-one (THDOC)，是一种内源性神经甾体，是 GABA_A 受体的正向调节剂。3α,21-Dihydroxy-5α-pregnan-20-one (THDOC) 增强神经元对低浓度 α4β1δ GABA_A 受体的反应。

3α,21-Dihydroxy-5α-pregnan-20-one-d₃ is the deuterium labeled 3α,21-Dihydroxy-5α-pregnan-20-one. 3α,21-Dihydroxy-5α-pregnan-20-one (THDOC), an endogenous neurosteroid, is a positive modulator of GABAA receptors. 3α,21-Dihydroxy-5α-pregnan-20-one potentiates neuronal response to low concentrations of GABA at α4β1δ GABAA receptors in vitro.
