Two γ‐hydroxybutyric acid (GHB) analogues, trans‐γ‐hydroxycrotonic acid (t‐HCA) and γ‐(p‐methoxybenzyl)‐γ‐hydroxybutyric acid (NCS‐435) displaced [3H]GHB from GHB receptors with the same affinity as GHB but, unlike GHB, failed to displace [3H]baclofen from GABAB receptors. The effect of the GHB analogues, GHB and baclofen, on G protein activity and hippocampal extracellular glutamate levels was compared. While GHB and baclofen stimulated 5′‐O‐(3‐[35S]thiotriphospate) [35S]GTPγS binding both in… CONTINUE READING
