Voacangine (12-methoxyibogamine-18-carboxylic acid methyl ester) is an alkaloid found predominantly in the rootbark of the Voacanga africana tree, as well as in other plants such as Tabernanthe iboga, Tabernaemontana africana, Trachelospermum jasminoides and Ervatamia yunnanensis. It is an iboga alkaloid which commonly serves as a precursor for the semi-synthesis of ibogaine. It has also been demonstrated in animals to have similar anti-addictive properties to ibogaine itself. Angiogenesis, the formation of new blood vessels from pre-existing ones, plays a critical role in normal and pathological phenotypes, including solid tumor growth and metastasis. Accordingly, the development of new anti-angiogenic agents is considered an efficient strategy for the treatment of cancer and other human diseases linked with angiogenesis.
