3-Oxo-14α,15α-epoxyschizozygine: A new schizozygane indoline alkaloid from Schizozygia coffaeoides
(University of Nairobi, 2014-07)The stem bark extract of the Schizozygia coffaeoides (Apocynaceae) showed moderate antiplasmodial activity (IC50 = 8–12 μg/mL) against the chloroquine-sensitive (D6) and chloroquine-resistant (W2) strains of Plasmodium ... -
Antiplasmodial and antileishmanial flavonoids from Mundulea sericea
(University of Nairobi, 2020)Five known compounds (1-5) were isolated from the extract of Mundulea sericea leaves. Similar investigation of the roots of this plant afforded an additional three known compounds (6-8). The structures were elucidated using ... -
