Abstract
The neurosteroids progesterone and allopregnanolone control numerous neuroprotective
functions in neural tissues, including inhibition of epileptic seizures and cell
death. Ganaxolone (3α-hydroxy-3β-methyl-5α-pregnan-20-one) (GNX) is the 3β-
methylated synthetic analog of allopregnanolone and an allosteric GABAA positive modulator.
Ganaxolone reduces the frequency of CDD-associated seizures.
