RAC BHFF is the potent and selective GABAB receptor positive allosteric modulator that increases the potency and efficacy of GABA. Exhibits anxiolytic and anticonvulsant activity in vivo and is orally active. RAC BHFF reduces alcohol’s reinforcing properties in alcohol-preferring rats and adds further support to the hypothesis that the positive allosteric modulators of the GABAB receptor may constitute a novel class of agents with therapeutic potential for alcohol dependence.
