    Product Description

    CGP 52432 is an antagonist of GABAB receptors.1 It selectively reverses (–)-baclofen-induced inhibition of potassium-evoked GABA release over glutamate or somatostatin release (IC50s = 0.085, 3.35, and 9.26 μM, respectively) from rat cortical synaptosomes. CGP 52432 (10 μM) reduces paired-pulse inhibition of monosynaptic inhibitory potentials (IPSPs) by 80% in CA1 pyramidal neurons in rat hippocampal slices.2 It increases cell proliferation in the ventral subgranular zone of the dentate gyrus when administered at a dose of 3 mg/kg per day for 21 days and reduces immobility in the forced-swim test when administered at 10 mg/kg in stress-sensitive BALB/c mice.3 CGP 52432 (30 mg/kg) increases locomotor activity in mice.4 It also inhibits the analgesic effects of isovaline, GABA, and baclofen (Item No. 18600) in a mouse model of hindpaw allodynia induced by prostaglandin E2 (PGE2; Item No. 14010).5
