Biochem/physiol Actions

Neurosteroid; positive allosteric modulator of the GABA_A receptor; anesthetic.

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