CGP-35348 is a compound used in scientific research which acts as an antagonist at GABAB receptors.[1][2][3]

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. [4] Moreover, CGP35348 was about threefold less potent to antagonize GHB and GBL than baclofen and SKF97541. [5]
