Quality Control of 17-PA

Chemical structure


Biological Activity of 17-PA

Selective antagonist of neurosteroid potentiation and direct gating of GABAA receptors. Selectively reduces the effects of 5α-reduced steroids compared to 5β-reduced steroids and displays no effect on potentiation evoked by barbiturates and benzodiazepines. Attenuates 3α,5α-THP-induced loss of righting reflex and total sleep time following i.c.v administration in rats.
