CGP-35348 was ineffective up to 100 μM to antagonize the inhibitory release of GABA elicited by baclofen, doing so selectively as a GABAB heteroreceptor antagonist.
[4] Moreover, CGP-35348 was about threefold less potent in antagonizing gamma-hydroxybutyrate (GHB) and gamma-butyrolactone (GBL) than baclofen and SKF-97,541.[5]
