Biological Activities
Strychnopsis thouarsii plays a vital role in Malagasy traditional medicine due to its potent antimalarial properties. Research indicates that decoctions from this plant can prevent infection by targeting the early liver stage of the Plasmodium parasite. Through bioassay-guided fractionation, scientists have isolated several new morphinan alkaloids, such as tazopsine, which demonstrate the ability to fully inhibit parasite growth in vitro. Additionally, the plant contains bisbenzylisoquinoline alkaloids like 7-O-demethyltetrandrine that exhibit significant antiplasmodial potency. These compounds may also act as adjuvants to chloroquine, potentially offering a way to combat drug-resistant strains of malaria.
Compounds
