(verify) cgp-35348 was ineffective up to 100 μm to antagonize the inhibitory release of gaba elicited by baclofen, doing it selective as gabab heteroreceptor antagonist. moreover, cgp-35348 was about threefold less potent to antagonize gamma-hydroxybutyrate (ghb) and gamma-butyrolactone (gbl) than baclofen and skf-97,541.
