Biological Activity for GS 39783

GS 39783 is a positive allosteric modulator of GABA_B receptor function. Potentiates the effects of GABA on [³⁵S]GTPγS binding at recombinant and native GABA_B receptors (EC₅₀ values are 2.1 and 3.1μM respectively). Decreases cocaine self-administration, blocks the rewarding properties of nicotine and produces anxiolytic-like activity without the side effects associated with baclofen or benzodiazepines.
