Voacamine, also known under the older names voacanginine and vocamine, is a naturally occurring dimeric indole alkaloid of the secologanin type, found in a number of plants, including Voacanga africana and Tabernaemontana divaricata. It is approved for use as an antimalarial drug in several African countries.[1] Voacamine exhibits cannabinoid CB1 receptor antagonistic activity.[2]

Chemistry
editStructure
editThere is considerable confusion about the absolute stereochemical configuration of voacamine and the originally published absolute structure had to be later revised.[3][4] It has an ibogaine unit joined with vobasine unit.
Adverse Effect
editVoacamine can cause hypertension in high dose.[5]
