MRK-016 is a functionally selective inverse agonist of ?5 subunit-containing GABAA receptors.{65493} It selectively binds to ?1-, ?2-, ?3-, and ?5 subunit-containing GABAA receptors (Kis = 0.83, 0.85, 0.77, and 1.4 nM, respectively) over those containing ?4 or ?6 subunits (Kis = 395 and >4,000 nM, respectively). It also selectively inhibits GABA-induced currents in mouse fibroblast L-M(TK-) cells expressing ?5 subunit-containing GABAA receptors over those containing ?1, ?2, or ?3 subunits. MRK-016 (3 mg/kg) reverses LPS-induced decreases in Bdnf expression, but not LPS-induced increases in amyloid-? levels, in the mouse hippocampus.{65494} It reverses LPS-induced inhibition of contextual fear acquisition in the same study, indicating a reversal of memory consolidation deficits.{65494} It enhances the performance of wild-type rats in a delayed matching-to-place water maze when administered at doses of 0.3, 1, and 3 mg/kg, indicating nootropic properties.{65493} MRK-016 also reduces immobility in the forced swim test in mice, an effect that can be blocked by the AMPA glutamate receptor antagonist NBQX (Item No. 14914).{65495} It does not potentiate proconvulsant activity induced by pentylenetetrazole (Item No. 18682) in mice when administered at doses up to 10 mg/kg.{65493}
