U 93631 is a GABAA receptor antagonist that binds picrotoxin site and stabilizes the inactive form of the channel via allosteric interaction. U 93631 accelerates decay of GABA-induced Cl- currents with little effect on peak amplitude. This compound also inhibits 5-HT3A receptors via a similar mechanism.
