distribution of insecticide-treated nets. Here, we provide an update on phenotypic IR in four highly malaria-endemic areas of PNG. IR against deltamethrin, lambda-cyhalothrin, and dichlorodiphenyltrichloroethane
Anti-malarial ozonides OZ439 and OZ609 tested at clinically relevant compound exposure parameters in a novel ring-stage survival assay (Publications)
BACKGROUND: Drug efficacy against kelch 13 mutant malaria parasites can be determined in vitro with the ring-stage survival assay (RSA). The conventional assay protocol reflects the exposure profile of
Cytochrome P450-mediated metabolism and CYP Inhibition for the synthetic peroxide antimalarial OZ439 (Publications)
OZ439 is a potent synthetic ozonide evaluated for the treatment of uncomplicated malaria. The metabolite profile of OZ439 was characterized in vitro using human liver microsomes combined with LC/MS-MS
Pyrethroid and etofenprox resistance in <em>Anopheles gambiae </em>and <em>Anopheles coluzzii </em>from vegetable farms in Yaounde, Cameroon:... (Publications)
Previous studies have indicated widespread insecticide resistance in malaria vector populations from Cameroon. However, the intensity of this resistance and underlying mechanisms are poorly known. Therefore
Differential infectivity of Plasmodium for mosquitoes (Publications)
The four human malarias - Plasmodium falciparum, P. vivax, P. ovale and P. malariaecan - canonly be transmitted by mosquitoes of the genus Anopheles, although not all species (nor all strains) of these
Potent antimalarials with development potential identified by structure-guided computational optimization of a pyrrole-based dihydroorotate... (Publications)
DHODH inhibitors have great potential for use in prophylaxis, which represents an unmet need in the malaria drug discovery portfolio for endemic countries, particularly in areas of high transmission in Africa
