Antiplasmodial hits. (a) Network of connections between drug targets and our Plasmodium hits. Overview of the compounds from the Maybridge hitfinder library identified as specific inhibitors of the following parasite (P. falciparum, Pf, square nodes; P. vivax, Pv, large circular nodes) targets: dihydrofolate reductase (DHFR), blue; drug-resistant dihydrofolate reductase (Rdhfr), light blue; N-myristoyltransferase (NMT), yellow; phosphoglycerate kinase (PGK), green. Small nodes represents hits with Tanimoto distance coefficients of  less than 0.4 (red), less than 0.5 (pink) or greater than 0.5 (blue) to Chemblntd compounds identified in P. falciparum in vitro screens (www.ebi.ac.uk/chemblntd). (b) Chemblntd compounds (compounds with demonstrated activity against P. falciparum in ex vivo assays) and similar hits identified in our screens as potentially targeting PvPGK. Schematic depicting the structures of PvPGK-specific compounds identified in screens and similar compounds with demonstrated activity against P. falciparum.
