  • Publication number: 20220289688
    Abstract: The disclosure is directed to compounds that bind to a target RNA molecule, such as a TPP riboswitch, compositions comprising the compounds, and methods of making and using the same. The compounds contain two structurally different fragments that allow for binding with the target RNA at two different binding sites thereby producing a higher affinity binding ligand compared to compounds that only bind to a single RNA binding site.
