Strychnogucine B is a bisindole alkaloid previously isolated fromStrychnos icajathat possesses promisingin vitroantiplasmodial properties. This compound was synthesized in four steps from (−)-strychnine. As no acute toxicity was observed at the highest tested cumulative dose of 60 mg/kg, itsin vivoantimalarial activity was determined intraperitoneally at 30 mg/kg/d in aPlasmodium bergheimurine model. In the Petersʼs 4-d suppressive test, this alkaloid suppressed the parasitaemia by almost 36% on day 5 and 60% on day 7 compared to vehicle-treated mice. In addition to this interesting antimalarial activity, it showed moderatein vitroantitrypanosomal activity but noin vivoactivity in an acuteTrypanosoma bruceimodel. It was also inactivein vitroonLeishmania mexicanapromastigotes. This highlights its selective antimalarial efficacy and leads to further investigation to assess its potential as new antimalarial lead compound.
