The partitions of the leaves of C. scabrum were analyzed for their antiproliferative activity on the same cell lines and the antimicrobial potential of this plant was also evaluated against 36 microorganisms.
In vivo anti-malarial activity and toxicity studies of triterpenic esters isolated form Keetia leucantha and crude extracts
Its activity can be explained by the presence of triterpenic acids and esters which in vivo activity and safety were demonstrated for the first time and brought out new information on the safety of K. leucantha use and on the identification of anti-malarial compounds from its dichloromethane extract.
In vivo Antimalarial and Antitrypanosomal Activity of Strychnogucine B, a Bisindole Alkaloid from Strychnos icaja.
Strychnogucine B is a bisindole alkaloid previously isolated from Strychnos icaja that possesses promising in vitro antiplasmodial properties and shows moderate in vitro antitrypanosomal activity but no in vivo activity in an acute Trypanosoma brucei model.
