AVN-492

Description: AVN-492 is a highly specific, selective and orally bioavailable antagonist of the 5-HT6R with Ki of 91 pM. The binding affinity of AVN-492 to 5-HT6R (Ki=91 pM) is more than three orders of magnitude higher than that to bind to the only other target, 5-HT2BR, (Ki=170 nM). Thus, the compound AVN-492 displayed great 5-HT6R selectivity against all other serotonin receptor subtypes, and is extremely specific against any other receptors such as adrenergic, GABAergic, dopaminergic, histaminergic, etc. AVN-492 demonstrates good in vitro and in vivo ADME profile with high oral bioavailability and good brain permeability in rodents. AVN-492 is a very promising tool for evaluating the role the 5-HT6 receptor might play in cognitive and neurodegenerative impairments. AVN-492 is an excellent drug candidate to be tested for treatment of such diseases, and is currently being tested in Phase I trials.
