Adatanserin (WY-50,324,SEB-324) is a mixed5-HT1A receptorpartial agonist and5-HT2A and5-HT2C receptorantagonist.[1][2][3] It was under development byWyeth as anantidepressant but was ultimately not pursued.[3][4]

Adantaserin has been shown to beneuroprotective againstischemia-inducedglutamatergicexcitotoxicity, an effect which appears to be mediated by blockade of the 5-HT2A receptor.[5]

Synthesis

[edit]

2-Chloropyrimidine (1) reacts withpiperazine (2), forming 2-(1-piperazinyl)pyrimidine (3). Treatment with thephthalimide derivative N-(2-bromoethyl)phthalimide (4) in analkylation reaction produces (5), which isdeprotected usinghydrazine to give theprimary amine (6).Amide formation with theacid chloride of1-adamantanecarboxylic acid yields adatanserin.[6][3]
