Despite the urgent need of a new antimalarial drugs, particularly those against multiresistant falciparum malaria, only a limited number of drugs are now at an advanced stage of preclinical or clinical development. They include artemisinin derivatives, pyronaridine and benflumetol (all originally developed in China), as well as new antifolate combinations, the hydroxynaphoquinone atovaquone whi...

Malaria kills over a million people each year. The loss of chloroquine due to the spread of parasite resistance is largely responsible for the resurgence of malaria. A new class of antimalarial drugs called artemisinins are available, but are unaffordable to most people in malaria-endemic countries and may quickly face the same fate as chloroquine unless they are combined with a partner drug. S...

This work studied the effect of malaria infection and antimalarial drugs on oxidative stress in 259 pregnant and nonpregnant women at Ade-Oyo hospital, Ibadan, Nigeria. Oxidative stress was determined by measuring serum lipid peroxidation, ascorbic acid, and reduced glutathione (GSH) levels using spectrophotometer. The results showed that mean lipid peroxidation was significantly higher (p < 0....

Malaria, the most prevalent and most pernicious parasitic disease of humans, is estimated to kill between one and two million people, mainly children, each year. Resistance has emerged to all classes of antimalarial drugs except the artemisinins and is responsible for a recent increase in malaria-related mortality, particularly in Africa. The de novo emergence of resistance can be prevented by ...

The development of new antimalarial therapeutics is necessary to address the increasing resistance to current drugs. Bicyclic azetidines targeting Plasmodium falciparum phenylalanyl-tRNA synthetase comprise one promising new class of antimalarials, especially due to their activities against three stages of the parasite's life cycle, but a lengthy synthetic route to these compounds may affect th...

Malaria is one of the most significant causes of infectious disease in the world. The search for new antimalarial chemotherapies has become increasingly urgent due to the parasites' resistance to current drugs. Ellagic acid is a polyphenol found in various plant products. In this study, antimalarial properties of ellagic acid were explored. The results obtained have shown high activity in vitro...

The use of antimalarial drugs in India has evolved since the introduction of quinine in the 17 th century. Since the formal establishment of a malaria control programme in 1953, shortly after independence, treatments provided by the public sector ranged from chloroquine, the mainstay drug for many decades, to the newer, recently introduced artemisinin based combination therapy. The complexity o...

The antimalaria effect of iron chelators is attributed to their interaction with a labile iron pool within parasitised erythrocytes, and it was postulated that increased affinity to iron as well as increased lipophilicity may improve antimalarial activity. In the present study we have examined the antimalarial effect of 3-hydroxypyridin-4-ones, a family of bidentate orally effective iron chelat...

Artemisinins have become essential antimalarial drugs for increasingly widespread drug-resistant malaria strains. Although tremendous efforts have been devoted to decipher how this class of molecules works, their exact antimalarial mechanism is still an enigma. Several hypotheses have been proposed to explain their actions, including alkylation of heme by carbon-centered free radicals, interfer...

Malaria's ability to rapidly adapt to new drugs has allowed it to remain one of the most devastating infectious diseases of humans. Understanding and tracking the genetic basis of these adaptations are critical to the success of treatment and intervention strategies. The novel antimalarial resistance locus PF10_0355 (Pfmspdbl2) was previously associated with the parasite response to halofantrin...
