A full GABAA agonist and partial GABAC agonist; binds GABAA on both high- and low-affinity sites (Kd = 10 and 270 nM, respectively), stimulating chloride efflux with an EC50 of 200 nM; activates GABAC receptors with an EC50 of 1.3 μM; impairs memory formation and retrieval; attenuates airway constriction.
