To evaluate the effects of isolated and combined artesunate (AS)/mefloquine (MQ) on embryo rats, pregnant rats were treated orally with AS (15 and 40 mg/kg body weight (bwt)/day), MQ (30 and 80 mg/kg bwt/day) and AS/MQ (15/30 and 40/80 mg/kg bwt/day) on days 9–11 post coitum (pc).
The results obtained indicate that compounds with one halogenous group substituted in position 6 and 7 provide an efficient approach for further development of antimalarial and antileishmanial agents. In addition, interesting ADME properties were found.
Our study investigated the possible impact of SP-IPT given to infants and children on the prevalence of SP-resistant haplotypes in the Plasmodium falciparum genes Pfdhfr and Pfdhps, comparing sites with and without IPTi/c. P. falciparum positive samples (N = 352) collected from children < 5 years were analyzed to determine the prevalence of SP resistance-related haplotypes by nested PCR followed by sequence-specific oligonucleotide probe-enzyme-linked immunosorbent assay.
Although many believe that the use of medicinal plants that have folklore reputations for antimalarial properties is relatively safe, many herbs may be potentially toxic due to their intrinsic adverse side effects. Therefore, herbal-derived remedies require powerful and deep assessment of their pharmacological qualities to establish their mode of action, safety, quality, and efficacy.
In the present study, we have used high-throughput screen datasets for the discovery of apicoplast inhibitors of the malarial pathogen as assayed from the delayed death response.
Our study has tried to address this gap by authenticating its traditional use for the treatment of malaria.
In this paper we review oxidative stress mechanisms involved in the disease and discuss the potential benefits of antioxidant supplementation as an adjuvant antimalarial strategy.
To further investigate the InsPx metabolism in these parasites a Plasmodium protein possessing inositol phosphate kinase (IPK) activity was recombinantly expressed, purified and enzymatically characterized for the first time
The aims of this study were to analyze the in vitro sensitivity of P. falciparum field isolates from Franceville, Gabon, to chloroquine (CQ), mefloquine (MF), dihydroartemisinine (DHA) and monodesethylamodiaquine (MDAQ), and to investigate polymorphisms associated with drug resistance.

Many of you will have come across counterfeit or substandard drugs in your careers and I’m sure many of you will understand my frustration. Therefore, I was really happy to see that the study on poor-quality anti-malarials by Dr Paul Newton and his team got the attention of the media. Even though their study was not large-scale and even though it cannot provide an accurate estimation of the prevalence of the fake anti-malarials all over Africa, it does provide an insight into the seriousness of the problem: it is severe!
