Activities of quinoxaline, nitroquinoxaline and [1,2,4]triazolo[4,3-a]quinoxaline analogs of MMV007204 against <em>Schistosoma mansoni</em> (Publications)
Recently, an antimalarial quinoxaline derivative (MMV007204) from the Medicines for Malaria Venture (MMV) Malaria Box demonstrated promise against Schistosoma mansoni In this study, 47 synthesized compounds

parasite is dominant. This compartmental model accounts specifically for the liver stages of P. vivax malaria and it has recently been refined to include imported infections as well as treatment of blood and/or [...] data on reported local and imported cases, and it can be used to simulate the expected impact of malaria treatment schemes, vector control strategies, reactive interventions or mass drug administration

isolates and lab-raised drug-resistant strains of Pf. It was efficacious in the humanized NSG mouse malaria infection model at a single oral dose of 32 mg/kg. This compound was nonteratogenic in the zebrafish [...] human dose, indicating that this series has the potential to deliver a preclinical candidate for malaria.
Fast-killing tyrosine amide ((<em>S</em>)-SW228703) with blood- and liver-stage antimalarial activity associated with the cyclic amine resistance... (Publications)
Current malaria treatments are threatened by drug resistance, and new drugs are urgently needed. In a phenotypic screen for new antimalarials, we identified (S)-SW228703 ((S)-SW703), a tyrosine amide with [...] fast-killing mechanism of action, available for lead optimization to generate new treatments for malaria.
Addressing the intracellular vestibule of the plasmodial lactate transporter PfFNT by p-substituted inhibitors amplifies in vitro activity (Publications)
Inhibition of the lactate transporter PfFNT is a valid novel mode of action against malaria parasites. Current pyridine-substituted pentafluoro-3-hydroxy-pent-2-en-1-ones act as substrate analogs with [...] metabolized, the more stable p-acetanilide cleared 99.7% of parasites at 4 × 50 mg kg(-1) in a mouse malaria model. Future stabilization of the p-substitution against metabolism may translate the gain in in

pleiotropic kinase phosphorylating substrates in different cellular compartments in eukaryotes. In the malaria parasite Plasmodium falciparum, PfCK2 is vital for asexual proliferation of blood-stage parasites [...] PfCK2alpha catalytic subunit in gametocytes, the sexual forms of the parasite that are essential for malaria transmission. We show that PfCK2alpha localizes to the nucleus and cytoplasm in asexual and sexual
