Identification of novel inhibitors of methionyl-tRNA synthetase (MetRS) by virtual screening

Multiple inhibitors of the antibacterial target, Staphylococcus aureus MetRS, were identified by virtual screening. The process consisted of building a Catalyst® pharmacophore from a ligand-S. aureus MetRS structure and using this pharmacophore to screen a commercial database. The top hits from this search were then docked into the S. aureus MetRS structure and this information was used to select compounds for testing. This resulted in a high hit rate of compounds that are in distinct structural classes from the known MetRS ligands.
