A variety of 2-amino-3-arylpropan-1-ols, anti-2-amino-3-aryl-3-methoxypropan-1-ols and anti-2-amino-1-arylpropan-1,3-diols were prepared selectively through elaboration of trans-4-aryl-3-chloro-β-lactams. In addition, a number of 2-(azidomethyl)aziridines was converted into novel 2-[(1,2,3-triazol-1-yl)methyl]aziridines by Cu(I)-catalyzed azide-alkyne cycloaddition, followed by microwave-assist...

7,20-Diisocyanoadociane, a scarce marine metabolite with potent antimalarial activity, was synthesized as a single enantiomer in 13 steps from simple building blocks (17 linear steps). Chemical synthesis enabled identification of isocyanoterpene antiplasmodial activity against liver-stage parasites, which suggested that inhibition of heme detoxification does not exclusively underlie the mechani...

The synthesis and physico-chemical properties of novel compounds obtained by conjugation of amodiaquine with moieties containing either furoxan or nitrooxy NO-donor substructures are described. The synthesised compounds were tested in vitro against both the chloroquine sensitive, D10 and the chloroquine resistant, W-2 strains of Plasmodium falciparum (P. falciparum). Most of the compounds showe...

phytochemical investigation of a dichloromethane-methanol (1:1) extract of the fruit pericarp of omphalocarpum procerum which exhibited antiplasmodial activity during preliminary screening led to the isolation of the new fatty ester triterpenoid 3β-hexadecanoyloxy-28-hydroxyolean-12-en-11-one (1), together with five known compounds 2-6. the structure of the new compound as well as those of the ...

The crude extract of the bark of Dehaasia longipedicellata exhibited antiplasmodial activity against the growth of Plasmodium falciparum K1 isolate (resistant strain). Phytochemical studies of the extract led to the isolation of six alkaloids: two morphinandienones, (+)-sebiferine (1) and (-)-milonine (2); two aporphines, (-)-boldine (3) and (-)-norboldine (4); one benzlyisoquinoline, (-)-retic...

Objective. The study was designed to determine the efficacy of combined Amodiaquine and Ciprofloxacin in plasmodiasis therapy. Method. The in vivo antiplasmodial effect of different dosage levels of Amodiaquine, Ciprofloxacin, and their combinations against Plasmodium berghei berghei was evaluated using Swiss albino mice. Results. Amodiaquine (a known antiplasmodial agent) had a fairly signific...

Introduction: The production of large amounts reactive oxygen species in severe malarial infection is due to parasite invasion erythrocytes. Malaria resistance medication has left malaria-endemic countries with no alternate source medications but traditional medicine. One such plants utilized by healers Phyllanthus amarus. Therefore, this study aims at ascertaining the antiplasmodial and cytoto...
