Abstract
Disclosed herein are compounds (such as peptides or peptide mimetics) that bind to HIV RRE RNA. In some examples, the compounds inhibit (for example, decrease) binding of Rev to the RRE RNA. In some embodiments, the compounds include two moieties, each of which bind to one of the Rev binding sites in the RRE. In some examples, the moieties include peptides or small molecules. In some examples, the peptides include an arginine-rich motif. The RRE binding compounds may be further linked to a detectable label or cargo moiety. Also disclosed are methods of treating or inhibiting HIV including administering one or more of the disclosed compounds to a subject.
Claims13
A compound that binds to a human immunodeficiency virus (HIV) Rev response element (RRE) RNA comprising two covalently linked peptides:
- wherein the RRE RNA comprises a first Rev binding site and a second Rev binding site and wherein the first peptide binds to the first Rev binding site and the second peptide binds to the second Rev binding site;
- and
- wherein the two peptides are joined by a linkage of about 30-80 Å;
- and
- wherein the first peptide binds to the first Rev binding site with an affinity of about 1 mM to 1 fM and the second peptide binds to the second Rev binding site with an affinity of about 1 mM to 1 fM.
