METHODS AND COMPOSITIONS FOR IDENTIFICATION OF INHIBITORS OF RIBOSOME ASSEMBLY

摘要

The invention provides a means for identifying novel antibiotics by screening for compounds that inhibit bacterial ribosome assembly and ribosomal protein synthesis, which comprises the screening of test compounds to identify those that inhibit the activity of a bacterial ribosomal protein. The in vitro and in vivo assays detect (a) increased translation of a reporter mRNA that is normally repressed in the presence of a ribosomal protein, (b) increased growth in cells that over-express ribosomal protein, and (c) decreased binding of the ribosomal protein to its target RNA. The invention encompasses the (a) methods of screening and testing compounds by the above methods, (b) compounds that are identified in the assay which inhibit ribosome assembly and protein synthesis and (c) methods for treatment using said compounds.
