Biochem/physiol Actions

Ganaxolone (3alpha-hydroxy-3beta-methyl-5alpha-pregnane-20-one) is a positive allosteric modulator of the GABAA receptor subtype; synthetic analog of the endogenous neurosteroid allopregnanolone; effective against chemically induced seizures in rats and mice. Ganaxolone is an orally active analog of allopregnanolone that is not converted to the hormonally active 3-keto form. The enhanced anticonvulsant potency of ganaxolone after neurosteroid withdrawal supports the use of ganaxolone as a specific treatment for perimenstrual catamenial epilepsy.

Low-frequency (6 Hz), long-duration (3 s) electrical stimulation in mice produces seizures characterized by immobility, focal clonus, and automatic behaviors reminiscent of human limbic epilepsy. Renewed interest has been expressed in this seizure model with the recognition that it is

The international journal of neuropsychopharmacology, 9(2), 191-200 (2005-09-22)
Accumulating evidence suggest a reciprocal interaction between neurosteroids, especially 5alpha-pregnan-3alpha-ol,20-one (3alpha,5alpha-THP, allopregnanolone), and the serotonergic (5-HT) system. Both 5-HT and neurosteroids seem to play an important role in the pathophysiology of major depression. We have previously shown that a 7-d

In women with epilepsy, seizures can be influenced by variations in sex hormone secretion during the menstrual cycle. The proconvulsant effects of estrogen have been demonstrated in both animals and humans, whereas progesterone has been found to have anticonvulsant properties.

Ganaxolone (3alpha-hydroxy-3beta-methyl-5alpha-pregnan-20-one) (GNX) is the 3beta-methylated synthetic analog of allopregnanolone; it belongs to a class of compounds referred to as neurosteroids. GNX is an allosteric modulator of GABA(A) receptors acting through binding sites which are distinct from the benzodiazepine binding

Ganaxolone (3alpha-hydroxy-3beta-methyl-5alpha-pregnane-20-one), an orally active synthetic analog of the neuroactive steroid allopregnanolone, is a positive allosteric modulator of gamma-aminobutyric acid(A) receptors with anticonvulsant properties. We sought to determine whether tolerance occurs to the anticonvulsant activity of ganaxolone in the pentylenetetrazol
