- Abstract
The methylerythritol 4-phosphate (MEP) pathway for the biosynthesis of the isoprenoid universal building blocks (isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP)) is present in most of human pathogens and is absent in animals, turning it into a promising therapeutic druggable pathway. Two different strategies, a pharmacophore-directed virtual screening and a protein-protein interaction (PPI)-mimicking cyclic peptide were used to search for compounds that bind to the PPI surface of the 4-(cytidine 5-diphospho)-2C-methyl-D-erythritol kinase (CMK), which catalyzes the fourth step of the MEP pathway. A significant part of the pharmacophore hypothesis used in this study was designed by mimicking water-mediated PPI relevant in the CMK homodimer complex stabilization. After database search and with the aid of docking and molecular dynamics (MD) simulations, a 7H-furo[3,2-g]chromen-7-one derivative and a cyclic peptide were chosen as candidates to be ligands of CMK. Their binding affinities were measured using surface plasmon resonance (SPR) technology. Copyright © 2010 John Wiley & Sons, Ltd.
