Integrin-binding peptides

Abstract

This invention is directed to novel integrin binding peptides. These peptides bind to αv- of α5-containing integrins and can exhibit high binding affinity. They contain one of the following sequence motifs: RX1ETX2WX3 [SEQ ID NO:1] (especially RRETAWA [SEQ ID NO:8]); RGDGX [SEQ ID NO:2], in which X is an amino acid with a hydrophobic, aromatic side chain; the double cyclic CX1CRGDCX2C [SEQ ID NO:15]; and RLD. The peptides generally exhibit their highest binding affinity when they assume a conformationally stabilized configuration. This invention also provides methods of using these peptides.
