Metabolite Identification
Common NameVoacamine
DescriptionVoacamine is only found in individuals that have used or taken this drug. It is an alkaloid isolated from the bark of the Pescheria fuchsiae folia tree. It is an antimalarial drug approved for use in several African countries. Voacamine is also under investigation for use in modulating multidrug-resistance in tumor cells. Voacamine is possibly a substrate for P-glycoprotein (P-gp), an efflux pump responsible for multidrug resistance in tumor cells. Voacamine may compete with anticancer drugs such as doxorubicin for P-gp transport, decreasing removal of doxorubicin.

Chemical Taxonomy
Description Belongs to the class of organic compounds known as ibogan-type alkaloids. These are indole alkaloids with a structure based on the ibogamine skeleton or a derivative thereof. Ibogamine is a pentacyclic heterocyclic compound consisting of an indole fused to an azepane-containing tricyclic moiety ring. Iboga alkaloids arise from the cyclization of a secodine-type precursor through the formation of a 16,21 bond.
