• Drug Groups: approved; investigational
• Description: Voacamine 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.
• Indication: For the treatment of malaria. Also under investigation for the modulation of multidrug resistance in cancer cells.
• Pharmacology: Voacamine is an anti-malarial extracted from the Brazilian tree Peschiera fuchsiaefolia. In one study (PMID: 11180519), the in vivo antiplasmodial activity of voacamine was assessed in a 4-day test. It was shown to exhibit in vivo activity with 25.4% and 43.4% inhibition of parasitaemia with 2.5 and 10 mg/kg, respectively. In synchronized cultures, it was found to act on trophozoite and schizont stages of Plasmodium falciparum.; Voacamine is a bisindolic alkaloid under investigation for modulation of multidrug resistance to enhance anticancer drugs such as doxorubicin.
