Scrophularia umbrosa is a medicinal plant used as a traditional herb. This study was designed to investigate the phytochemical analysis of methanol (MeOH), DCM, and n-Hexane extracts of rhizome as well as total phenol and total flavonoid contents (TPC and TFC). In-vitro β-hematin formation assay and DPPH method were applied for analyzing antimalarial and free-radical scavenging activities of th...
Malaria is a clear example of a reemerging disease. The annual number of cases (incidence) fell sharply 30-35 years ago as the result of a malaria eradication campaign (1, 2). At that time, malaria was eliminated from Europe, most Asian regions of the USSR, the United States, and most of the Caribbean (3). However, it was not eradicated in Southeast Asia, South America, or Africa, and has reeme...
Methods and techniques for clinical trials on antimalarial drug effi cacy: genotyping to identify parasite populations: informal consultation organized by the Medicines for Malaria Venture and cosponsored by
BACKGROUND Malaria is a highly debilitating and frequently fatal disease of wide distribution. Improper drug storage and rampant self-medication are some of the factors that may contribute to an increase in the development of drug resistance by malaria parasites towards antimalarials. OBJECTIVES To determine the extent of antimalarial drugs storage, sources and associated factors at household...
We formulate and analyze a mathematical model for malaria with treatment and the well-known three levels of resistance in humans. The model incorporates both sensitive and resistant strains of the parasites. Analytical results reveal that the model exhibits the phenomenon of backward bifurcation (co-existence of a stable disease-free equilibrium with a stable endemic equilibrium), an epidemiolo...
Evaluation of a simple operational approach for monitoring resistance to antimalarial drugs in Peru.
Since 1994, the Peruvian Malaria Control Program has used a simplified operational approach for monitoring antimalarial drug efficacy, in which blood smears are taken 7 and 14 days after treatment from all patients diagnosed with malaria at Ministry of Health facilities. The proportion of patients with parasitaemia on one of their return visits provides an indication of the efficacy of the drug...
We have tested five distinct classes of established and experimental antimalarial drugs for their anticancer potential, using a panel of 91 human cancer lines. Three classes of drugs: artemisinins, synthetic peroxides and DHFR (dihydrofolate reductase) inhibitors effected potent inhibition of proliferation with IC50s in the nM- low µM range, whereas a DHODH (dihydroorotate dehydrogenase) and a ...
BACKGROUND Many acute and chronic neurological sequelae from the quinoline derivative antimalarial drug mefloquine, including dizziness and effects on the visual system such as diplopia and blurred vision, may be attributable to focal central nervous system toxicity. Maculopathy has also been reported with use of mefloquine, although the mechanism of this effect has remained unclear. Identifica...
Mefloquine has been one of the more valuable antimalarial drugs but has never reached its full clinical potential due to concerns about its neurologic side effects, its greater expense than that of other antimalarials, and the emergence of resistance. The commercial development of mefloquine superseded that of another quinolinyl methanol, WR030090, which was used as an experimental antimalarial...
