Alstonine is an indole alkaloid and putative antipsychotic constituent of various plant species including Alstonia boonei, Catharanthus roseus, Picralima nitida, Rauwolfia caffra and Rauwolfia vomitoria.[1] In preclinical studies alstonine attenuates MK-801-induced hyperlocomotion, working memory deficit and social withdrawal.[2] It also possesses anxiolytic-like effects in preclinical studies.[1] It also attenuates amphetamine-induced lethality and stereotypy as well as apomorphine-induced stereotypy.[1] It also attenuates haloperidol-induced catalepsy.[3] These effects appear to be mediated by stimulation of the 5-HT2C receptor.[4] It also, similarly to clozapine, inhibits the reuptake of glutamate in hippocampal slices.[5] Unlike clozapine, however, it lacks pro-convulsant activity in mice.[6]
