Piperazinylpyrazines with central serotoninmimetic activity.

Article abstract of DOI:10.1021/jm00204a007

A series of 2-(1-piperazinyl)pyrazines was synthesized and evaluated for central serotonin-like activity. The most interesting member of the series, 6-chloro-2(1-piperazinyl)pyrazine (3a), had pharmacological properties characteristic of potent central serotoninmimetic activity and only weak peripheral serotoninmimetic action. Structural similarities between 3a and serotonin are discussed.
