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]

Pharmacology

Limited pharmacological testing has indicated that affinisine may effectively inhibit acetylcholinesterase and butyrylcholinesterase.[1][5]
