Malaria elimination in the Greater Mekong Sub-Region is challenged by a rising proportion of malaria attributable to P. vivax. Primaquine (PQ) is effective in eliminating the parasite's dormant liver stages and can prevent relapsing infections, but it induces severe haemolysis in patients with Glucose-6-Phosphate Dehydrogenase (G6PD) deficiency, highlighting the importance of testing enzyme activity prior to treatment.

NOT Open Access | Computational chemogenomics drug repositioning strategy enables the discovery of Epirubicin as a new repurposed hit for P. falciparum and P. vivax

Widespread resistance against antimalarial drugs thwarts current efforts for controlling the disease and urges the discovery of new effective treatments. Drug repositioning is increasingly becoming an attractive strategy since it can reduce costs, risks and time-to-market. Herein we have used this strategy to identify novel antimalarial hits. We performed a comparative in silico chemogenomics approach to select Plasmodium falciparum and P. vivax proteins as potential drug targets and analyzed these using a computer-assisted drug repositioning pipeline to identify approved drugs with potential antimalarial activity. Among seven drugs identified as promising antimalarial candidates, the anthracycline epirubicin was selected for further experimental validation.

Comprehensive proteomics investigation of P. vivax-infected human plasma and parasite isolates

In recent times, Plasmodium vivax (P. vivax) has become a serious threat to public health due to its ability to cause severe infection with fatal outcomes. Its unique biology makes it resilient to control measures that are otherwise effective against P. falciparum. A deeper understanding of P. vivax biology and pathogenesis is, therefore, essential for developing the right control strategies. 

Humoral immunity prevents clinical malaria during Plasmodium relapses without eliminating gametocytes

Plasmodium relapses are attributed to the activation of dormant liver-stage parasites and are responsible for a significant number of recurring malaria blood-stage infections.

Phosphoethanolamine-N-methyltransferase is a potential biomarker for the diagnosis of P. knowlesi and P. falciparum malaria

PMT, like the pan-specific LDH biomarker used in RDT tests, is both soluble, present at comparable concentrations in the parasite and constitutes a promising antimalarial drug target.
