Natural product-derived drugs exemplified by quinine, isolated from South American Cinchona species and artemisinin discovered in China are of immense importance for the treatment of malaria. Although malaria parasites resistant to artemisinin have not yet been found in malaria patients, the need for new antimalarial agents remains. The burden of malaria is heaviest in Africa where over a milli...

Objective:Zea mays root decoction that has been traditionally used for the treatment of malaria by various tribes in Nigeria, was evaluated for antimalarial potential against malaria parasites using in vivo and in vitro models. Materials and Methods: The root extract of Zea mays was investigated for antimalarial activity against Plasmodium berghei in mice using rodent malaria models; suppressiv...

background: resistance to most antimalarial drugs has encouraged the development of novel drugs. an alternative source for discovering such drugs is natural products. some ferulago species are used in folk medicine for their sedative, tonic and anti-parasitic effects. besides, coumarins isolated from this genus found to have in vitro anti-leishmanicidal effect. the present study is aimed to eva...

Leishmaniasis and malaria are serious public health problems in tropical and sub-tropical regions worldwide. Development of drug-resistant strains has disrupted efforts to control the spread of these diseases in the world. The conventional antiparasitic chemotherapy still suffers from side effects and drug resistance. Therefore, the development of novel antimalarial and leishmanicidal drugs rem...

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...

The evaluation of new antimalarial agents using older methods of monitoring sensitivity to antimalarial drugs are laborious and poorly suited to discriminate stage-specific activity. We used flow cytometry to study the effect of established antimalarial compounds, cysteine protease inhibitors, and a quinolone against asexual stages of Plasmodium falciparum. Cultured P. falciparum parasites were...

The methanolic extract of Languas galanga rhizomes was investigated for antimalarial activity against Plasmodium berghei (NK65) infections in mice. The median lethal dose was determined to ascertain the safety of the extract in ICR mice of both sexes. The antimalarial activities during early and established infections, as well as the prophylactic activity were evaluated. Phytochemical screening...
