the formation of hemozoin (malaria pigment) has been proposed as an ideal drug target for antimalarial screening programs. in this study, we used an improved, cost-effective and high-throughput spectrophotometric assay to screen plant extracts for finding novel antimalarial plant sources. fifteen extracts with different polarity from three iranian artemisia species, a. ciniformis, a. biennis an...

Malaria eradication is a major goal in public health but is challenged by relapsing malaria species, expanding drug resistance, and the influence of host genetics on antimalarial drug efficacy. To overcome these hurdles, it is imperative to establish in vitro assays of liver-stage malaria for drug testing. Induced pluripotent stem cells (iPSC) potentially allow the assessment of donor-specific ...

The aim of this study was to review the antimalarial drug treatment and its resistance during the course of therapy. Malaria affects the populations of tropical and subtropical areas world-wide, as well as an increasing number of travellers to these areas. Although malaria is found in over 100 countries, the major burden of disease is carried by the nations of Africa, where over 90% of all deat...

BACKGROUND Home management of uncomplicated malaria (HMM) is now integrated into the community case management of childhood illness (CCM), an approach that requires parasitological diagnosis before treatment. The success of CCM in resource-constrained settings without access to parasitological testing significantly depends on the caregiver's ability to recognise malaria in children under five y...

Comparative mutagenic and genotoxic effects of three antimalarial drugs, chloroquine, primaquine and amodiaquine, were assessed in the Ames mutagenicity assay (in strains TA97a, TA100, TA102 and TA104) and in vivo sister chromatid exchange (SCE) and chromosome aberration (CA) assays in bone marrow cells of mice. These are the most commonly used antimalarial drugs available at present throughout...

Drug resistance is a recurrent problem in the fight against malaria. Genetic and epidemiological surveillance of antimalarial resistant parasite alleles is crucial to guide drug therapies and clinical management. New antimalarial compounds are currently at various stages of clinical trials and regulatory evaluation. Using ∼2000 Plasmodium falciparum genome sequences, we investigated the genetic...

Prices of new antimalarial drugs are targeted at the "travellers' market" in developed countries, which makes them unaffordable in malaria-endemic countries where the per capita annual drug expenditures are US$ 5 or less. Antimalarials are distributed through a variety of channels in both public and private sectors, the official malaria control programmes accounting for 25-30% of chloroquine di...

Alternative drugs to chloroquine are required to prevent the deleterious effects of malaria in pregnancy. Fear of potential toxicity has limited antimalarial drug use in pregnancy. Animal toxicity studies have documented teratogenicity when antimalarials are administered at high dosages. Excepting the tetracyclines, there is no evidence to suggest that, at standard dosages, any of the antimalar...

Objective: Current therapies to treat P. falciparum malaria are heavily reliant on artemisinin-based combinations. However, resistance to artemisinin has recently been identified, and resistance to key artemisinin partner drugs is already widespread. Therefore, there is an urgent need for new antimalarial drugs with improved attributes over older therapies. The objective of this research work i...
