MedKoo CAT#: 522997

CAS#: 554403-08-6 (HCl)

Description: WAY-181187 is a potent and selective 5-HT6 receptor agonist. WAY-181187 possesses high affinity binding (2.2 and 4.8 nM, respectively) at the human 5-HT6 receptor and profile as full receptor agonists (WAY-181187: EC50=6.6 nM, Emax=93%). In the rat frontal cortex, acute administration of WAY-181187 (3-30 mg/kg, subcutaneous (s.c.)) significantly increased extracellular GABA concentrations without altering the levels of glutamate or norepinephrine.
