New antimalarial drug candidates that act via novel mechanisms are urgently needed to combat malaria drug resistance. Here, we describe the multi-omic chemical validation of Plasmodium M1 alanyl metalloaminopeptidase as an attractive drug target usin

ABSTRACT To combat the global burden of malaria, development of new drugs to replace or complement current therapies is urgently required. Here, we show that the compound MMV1557817 is a selective, nanomolar inhibitor of both Plasmodium falciparum an

Antimalarial resistance to the first-line partner drug piperaquine (PPQ) threatens the effectiveness of artemisinin-based combination therapy. In vitro piperaquine resistance is characterized by incomplete growth inhibition, i.e. increased parasite g

Here, de Vries et al. perform a pre-clinical characterization of the antimalarial compound MMV693183: the compound targets acetyl-CoA synthetase, has efficacy in humanized mice against Plasmodium falciparum infection, blocks transmission to mosquito

We describe our work resulting in the selection of ACT-451840 ( 38 ) as a novel antimalarial drug with a novel mode of action. The compound was broadly characterized in vitro as well as in vivo in rat PK experiments as well as two different mouse mal

Hitz et al. describe the role of the protein kinase PfCK2α in the development of the human malaria parasite Plasmodium falciparum. Using mutant parasites, they show that PfCK2α is not only essential for asexual but also sexual development of P. fal

Abstract Background Emergence of anti-malarial drug resistance and perpetual increase in malaria incidence necessitates the development of novel anti-malarials. Histone deacetylases (HDAC) has been shown to be a promising target for malaria, despite
