Biological Activities
Strychnos usambarensis contains several alkaloids that demonstrate significant antiplasmodial potential. Research has shown that specific compounds, such as strychnopentamine and 3',4'-dihydrousambarensine, exhibit high levels of activity against Plasmodium falciparum during in vitro testing. While these alkaloids show promise in a controlled laboratory setting, their effectiveness against Plasmodium berghei in vivo remains limited. The study further explores how various derivatives, including usambarensine and usambarine, interact with different protozoa. Ultimately, understanding these structure-activity relationships is crucial for evaluating the pharmacological properties of this plant.
Compounds
Strychnos usambarensis serves as a rich botanical source for a diverse array of potent indole alkaloids. Research into the plant's roots has successfully identified several key compounds, including the tertiary amine usambarensine. The species also contains 10'-hydroxyusambarensine, a bisindole alkaloid noted for its antimalarial properties. Furthermore, the plant yields various bisquaternary ammonium derivatives such as afrocurarine and C-curarine, which act as neuromuscular blocking agents.
