Adatanserin (WY-50,324, SEB-324) is a mixed 5-HT1A receptor partial agonist and 5-HT2A and 5-HT2C receptor antagonist.[1][2][3] It was under development by Wyeth as an antidepressant but was ultimately not pursued.[3][4]

Adantaserin has been shown to be neuroprotective against ischemia-induced glutamatergic excitotoxicity, an effect which appears to be mediated by blockade of the 5-HT2A receptor.[5]
