Adatanserin
Adatanserin (WY-50,324, SEB-324) is a mixed 5-HT receptor partial agonist and 5-HT and 5-HT receptor antagonist. It was under development by Wyeth as an antidepressant but was ultimately not pursued.
Adantaserin has been shown to be neuroprotective against ischemia-induced glutamatergic excitotoxicity, an effect which appears to be mediated by blockade of the 5-HT receptor.
