Biological Activity

GR3027 (Golexanolone) is a GABA-A receptor modulating steroid antagonist that selectively antagonizes the enhanced activation of GABAA receptors by neurosteroids such as allopregnanolone and THDOC; inhibits α1β2γ2L receptor 29 ± 5% of THDOC enhancement of the GABA response, does not antagonize the effect of GABA at the GABAA receptor; during the specific conditions used for the different receptors, IC50=250 nM for the α1β2γ2L GABAA receptor and 350 nM for the α5β3γ2L GABAA receptor; restores spatial learning and motor coordination in rats with chronic hyperammonemia and hepatic encephalopathy.
