Chemical compound
Akuammine (vincamajoridine[2] ) is an indole alkaloid. It is the most abundant alkaloid found in the seeds from the tree Picralima nitida ,[3] commonly known as akuamma, comprising 0.56% of the dried powder. It has also been isolated from Vinca major .[2] Akuammine is structurally related to yohimbine, mitragynine and more distantly Voacangine, all of which are alkaloid plant products with pharmacological properties.
Pharmacology
[edit ]Akuammine has antimalarial activity,[3] and may be the primary constituent of P. nitida seeds responsible for this activity.[4]
Akuammine is an opioid agonist with low affinity, selective for the mu-opioid receptor, when tested in vitro .[5] [6]
