An aminoacylation/translation (AIT) system based on the protein synthesis system from the pathogen Pseudomonas aeruginosa , was used to screen chemical compounds for identifying inhibitors of protein synthesis. This system includes elongation factors: EF-Tu, EF-Ts and EF-G, aminoacyl tRNA synthetase (aaRS) specific for phenylalanine, PheRS, and ribosomes isolated from cultures of Pseudomonas aeruginosa . Compounds identified using this assay have been shown to contain broad spectrum activity against both Gram+ and Gram− pathogens. Methods of using the identified compounds, as well as derivatives and analogues of these compounds, as antimicrobial agents against bacterial infections are described. |
