Design, docking studies and molecular dynamics of new potential selective inhibitors of Plasmodium falciparum serine hydroxymethyltransferase

In this paper, former studies on the interactions of the natural substrate and potential inhibitors of Plasmodium falciparum serine hydroxymethyltransferase (PfSHMT) were used to design five new potential selective inhibitors to this enzyme. Results of the docking energies calculations of these structures inside the active sites of PfSHMT and human SHMT were used to select a more suitable structure as a potential selective inhibitor to PfSHMT. Further molecular dynamics studies of this molecule and 5-formyl-6-hydrofolic acid (natural substrate) docked inside these enzymes' active sites revealed important features for additional refinements of this structure and also additional residues in the PfSHMT active site to be considered further for designing selective inhibitors.
