Imaging of <em>Plasmodium</em> liver stages to drive next-generation antimalarial drug discovery (Publications)
Most malaria drug development focuses on parasite stages detected in red blood cells, even though to achieve eradication, next-generation drugs active against both erythrocytic and exo-erythrocytic forms [...] imidazolopiperazine confers complete causal prophylactic protection (15 mg/kg) in rodent models of malaria and shows potent in vivo blood-stage therapeutic activity. The open source chemical tools resulting
Trisubstituted pyrimidines as efficacious and fast-acting antimalarials (Publications)
mouse model of malaria. The most promising compound (13) showed a reduction in parasitemia of 96% when dosed at 30 mg/kg orally once a day for 4 days in the P. berghei mouse model of malaria. It also demonstrated
The epidemiology of multiple <em>Plasmodium falciparum</em> infections. 7. Dynamics of multiple <em>Plasmodium falciparum </em>infections in infants... (Publications)
The force of infection and recovery rate for malaria in infants in a highly endemic area of Tanzania were analysed using polymerase chain reaction-restriction fragment length polymorphism genotyping of [...] recovery rates were in children under 4 months of age. The higher susceptibility of infants to clinical malaria in comparison with older children, in areas of very high transmission, may be largely a consequence
Discovery and characterization of ACT-451840: an antimalarial drug with a novel mechanism of action (Publications)
More than 40 % of the world's population is at risk of being infected with malaria. Most malaria cases occur in the countries of sub-Saharan Africa, Central and South America, and Asia. Resistance to standard
Systematic review of indoor residual spray efficacy and effectiveness against <em>Plasmodium falciparum</em> in Africa (Publications)
Indoor residual spraying (IRS) is an important part of malaria control. There is a growing list of insecticide classes; pyrethroids remain the principal insecticide used in bednets but recently, novel [...] of different IRS insecticides. We report that long-lasting IRS formulations substantially reduce malaria, though their benefit over cheaper, shorter-lived formulations depends on local factors including
On a mission to block transmission (Publications)
falciparum parasites could provide a platform to evaluate new drugs and vaccines aimed at blocking malaria transmission.
Multiplexed ddPCR-amplicon sequencing reveals isolated <em>Plasmodium falciparum</em> populations amenable to local elimination in Zanzibar, Tanzania (Publications)
Zanzibar has made significant progress toward malaria elimination, but recent stagnation requires novel approaches. We developed a highly multiplexed droplet digital PCR (ddPCR)-based amplicon sequencing [...] genetic structure across the Zanzibar archipelago and provides actionable insights for prioritizing malaria elimination efforts.
Structure-activity relationships and antiplasmodial potencies of novel 3,4-disubstituted 1,2,5-oxadiazoles (Publications)
The 4-substituted 3-amino-1,2,5-oxadiazole 1 from the Malaria Box Project of the Medicines for Malaria Venture foundation shows very promising selectivity and in vitro activity against Plasmodium falciparum
Discovery and characterization of potent, efficacious, orally available antimalarial plasmepsin X inhibitors and preclinical safety assessment of... (Publications)
Plasmepsin X (PMX) is an essential aspartyl protease controlling malaria parasite egress and invasion of erythrocytes, development of functional liver merozoites (prophylactic activity), and blocking [...] days. This work demonstrates the potential to deliver PMX inhibitors with in vivo efficacy to treat malaria.
Novel antimalarial tetrazoles and amides active against the hemoglobin degradation pathway in <em>Plasmodium falciparum</em> (Publications)
Malaria control programs continue to be threatened by drug resistance. To identify new antimalarials, we conducted a phenotypic screen and identified a novel tetrazole-based series that shows fast-kill [...] polymerization pathway and that can form the basis of future optimization efforts to develop a new malaria treatment.
