    Product Description

    AVN-492 is an antagonist of the serotonin (5-HT) receptor subtype 5-HT6 (Ki = 0.09 nM).1 It selectively inhibits the 5-HT6 receptor over the 5-HT2B receptor (IC50s = 0.19 and 268 nM, respectively, in a radioligand binding assay). AVN-492 inhibits increases in cAMP levels induced by 5-HT in HEK293 cells expressing the 5-HT6 receptor (IC50 = 1.5 nM). It increases the time spent in the open arms of the elevated plus maze in rats, indicating anxiolytic activity, when administered at a dose of 0.2 mg/kg. AVN-492 (1 mg/kg) also prevents memory deficits induced by the NMDA receptor antagonist MK-801 in a passive avoidance test.

    WARNING This product is not for human or veterinary use.
