Affinisine
Affinisine is a monoterpenoid indole alkaloid which can be isolated from plants of the genus Tabernaemontana.[1][2] Structurally, it can be considered a member of the sarpagine alkaloid family and may be synthesized from tryptophan via a Pictet-Spengler reaction.[3][4] Limited pharmacological testing has indicated that affinisine may effectively inhibit acetylcholinesterase and butyrylcholinesterase.This article about an alkaloid is a stub.You can help Wikipedia by expanding it.
