Biochem/physiol Actions

Neurosteroid; positive allosteric modulator of the GABAA receptor; anesthetic.
Synthetic steroid compound alphaxalone (AFX) - 5α-Pregnan-3α-ol-11,20-dione- is a neurosteroid that directly activates and potentiates GABAA receptor-activated membrane current (IGABA). It acts as a positive allosteric modulator of the GABAA receptor; anesthetic. The alpha subunit subtype of GABAA determines the efficacy, but not the potency, of AFX neuroactive steroid to potentiate IGABA.

Neuropharmacology, 37(9), 1103-1110 (1998-12-02)
The effects of increased membrane cholesterol on the potentiation of GABA(A) currents by pregnanolone (5beta-pregnan-3alpha-ol-20-one), allopregnanolone (5alpha-pregnan-3alpha-ol-20-one), alphaxalone (5alpha-pregnan-3alpha-ol-11,20-dione) and propofol were investigated in acutely dissociated rat hippocampal neurones using the whole-cell patch clamp technique. Cholesterol enrichment of the neurones
R Maitra et al.
Brain research, 819(1-2), 75-82 (1999-03-20)
Neurosteroids are potent, endogenous modulators of GABAA receptor function in the central nervous system. The endogenous progesterone metabolite allopregnanolone (ALP) and the synthetic steroid compound alphaxalone (AFX) have been shown to both directly activate and potentiate GABAA receptor-activated membrane current
