Abstract: Methods of inhibiting S. aureus propagation, and screening for compounds that inhibit S. aureus propagation, are described. A method of inhibiting S. aureus propagation comprises inhibiting ribosomal binding of a specific S. aureus tRNA in the S. aureus by an amount sufficient to inhibit S. aureus protein expression. A method of screening for compounds useful for inhibiting S. aureus propagation comprises contacting a specific S. aureus tRNA to a ribosome that binds that tRNA in the presence of the test compound, and then determining whether the compound inhibits the binding of that tRNA.

Abstract: Methods of identifying inhibitors of retroviral propagation, tRNA used in the methods, and kits, including the tRNA, which can be used in the methods, are disclosed. Methods of treating or preventing retroviral infections by administering an effective amount of the inhibitors, and pharmaceutical compositions including the inhibitors, are also disclosed. The methods involve forming a mixture comprising a linear sequence of a tRNA anticodon stem loop fragment that is not capable of forming a stem-loop, a target nucleic acid molecule capable of binding to the tRNA anticodon stem loop fragment, and a test compound. The mixture is incubated under conditions that allow binding of the tRNA anticodon stem loop fragment and the target nucleic acid molecule in the absence of the test compound. Assays can then be performed that detect whether or not the test compound inhibits the binding of the tRNA anticodon stem loop fragment and the target nucleic acid molecule.

Abstract: Compositions and methods for identifying inhibitors of RNA-target molecule interactions are provided as well as identifying inhibitors that block the role of tRNA in protein synthesis. The methods involve forming a mixture comprising a tRNA fragment molecule containing a modified nucleotide, a target molecule capable of binding to the tRNA fragment, and a test compound. The mixture is incubated under conditions that allow binding of the tRNA and the target molecule in the absence of the test compound. Assays can then be performed that detect whether or not the test compound inhibits the binding of the tRNA molecule and the target molecule. High throughput assays are also provided.
