Bioassay-directed fractionation provided two new limonoids, trichirubines A and B, which may be helpful in recovering naturally occurring compounds of medicinal significance for human medicine.
Ugandenial A, a New Drimane-type Sesquiterpenoid from Warburgia ugandensis
One new drimane-type sesquiterpenoid was isolated from the ethyl acetate extract of the bark of Warburgia ugandensis (Canellaceae) together with eight known drimanes- type sesQUiterpenoids, establishing their structures by detailed spectroscopic analysis.
Antiplasmodial phenolic compounds from Piptadenia pervillei.
Five analogues of (+)-catechin 5-gallate were synthesized and evaluated for their antiplasmodial activity and displayed the highest in vitro activity against the chloroquine-resistant strain FcB1 of Plasmodium falciparum.
