Anti-plasmodial flavonoids from the stem bark of Erythrina abyssinica
Abiy Yenesew,Martha Induli,Solomon Derese,Jacob O. Midiwo,Matthias Heydenreich,Martin G. Peter,Hoseah M. Akala,Julia Wangui,Pamela Liyala,Norman C. Waters +9 more
TL;DR: From the ethyl acetate extract of the stem bark of Erythrina abyssinica, a new chalcone, 2',3,4,4'-tetrahydroxy-5-prenylchalcone (trivial name 5- prenylbutein) and a new flavanone along with known flavonoids have been isolated as the anti-plasmodial principles.
Journal ArticleDOI

Abiy Yenesew,Solomon Derese,Jacob O. Midiwo,Hellen A. Oketch-Rabah,J. N. Lisgarten,J. N. Lisgarten,Rex A. Palmer,Matthias Heydenreich,Martin G. Peter,Hosea Akala,Julia Wangui,Pamela Liyala,Norman C. Waters +12 more
TL;DR: The dichloromethane extract of the stem bark of Millettia usaramensis subspecies usaramense showed anti-plasmodial activity against the chloroquine sensitive (D6) andchloroquine resistant (W2) strains of Plasmodium falciparum.
Journal ArticleDOI
Flavonoids and Isoflavonoids with Antiplasmodial Activities from the Root Bark of Erythrina abyssinica
Abiy Yenesew,Solomon Derese,Beatrice Irungu,Jacob O. Midiwo,Norman C. Waters,Pamela Liyala,Hoseah M. Akala,Matthias Heydenreich,Martin G. Peter +8 more
TL;DR: The crude extract and the flavonoids and isoflavonoids obtained from the roots of this plant showed antiplasmodial activities.
Journal ArticleDOI
Antiplasmodial flavonoids from Erythrina sacleuxii.
Andrew W. Andayi,Abiy Yenesew,Solomon Derese,Jacob O. Midiwo,Peter M. Gitu,Ogoche J. I. Jondiko,Hosea Akala,Pamela Liyala,Julia Wangui,Norman C. Waters,Matthias Heydenreich,Martin G. Peter +11 more
TL;DR: Chromatographic separation of the acetone extract of the root bark afforded a new is oflavone, 7-hydroxy-4'-methoxy-3'-prenylisoflavone (trivial name 5-deoxy-2'-3'- prenylbiochanin A) along with known isoflavonoids as the antiplasmodial principles.

TL;DR: In this article, the drug resistance profiles of Plasmodium falciparum isolated from four regions in Kenya were analyzed for drug resistance profile and observed variability in resistance to a broad range of antimalarial drugs across Kenya as determined from in vitro drug susceptibility screening and genotyping analysis.
