Androsterone, a neurosteroid, acts as a positive allosteric modulator of GABA(A) receptors, that can cross into the brain and could have effects on brain function. It was discovered, that the association of beta subunits with alpha subunits GABA(A) receptor affects the sensitivity of glycine receptors to androsterone. In spite of that, androsteron is considered as an inactive metabolite of testosterone. In addition, was studied that androsterone possessed anticonvulsant properties. Although of low potency, the androsterone was present in high abundance and was able to represent endogenous modulator of seizure susceptibility.

Anticonvulsant potency in mice:

Route of Administration: Intraperitoneal

In Vitro Use Guide

Solutions of androsterone (5α,3α-A), its 5β-epimer etiocholanolone (5β,3α-A) and unnatural enantiomers: ent-5α,3α-A and ent-5β,3α-A were made fresh daily in 40% hydroxypropyl-β-cyclodextrin in sterile 0.9% saline. The convulsant agent pentylenetetrazol (PTZ) was dissolved in saline immediately before use. All drug solutions were administered in a volume equaling 0.01 ml/g body weight. In the convulsant pentylenetetrazol (PTZ), 6-Hz and maximal electroshock (MES) seizure tests, the steroids or vehicle were administered intraperitoneally 15 min before PTZ or electrical stimulation. It was found that in addition to greater potency, the eutomers have more prolonged durations of action likely as a result of greater metabolic stability.
