This invention is directed to novel integrin binding peptides. These peptides bind to αv- or α5-containing integrins and can exhibit high binding affinity. They contain one of the following sequence motifs: RX1ETX2WX3 [SEQ ID NO: i] (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.
本发明涉及新型整合素结合肽。这些肽能与αv-或α5-含整合素结合,并表现出很高的结合亲和力。它们包含以下序列图案之一:RX1ETX2WX3[
SEQ ID NO: i](尤其是 RRETAWA [
SEQ ID NO: 8]);RGDGX[
SEQ ID NO: 2],其中 X 是具有疏
水芳香侧链的
氨基酸;双环 CX1CRGDCX2C [
SEQ ID NO:- 15];以及 RLD。这些肽通常在构象稳定时表现出最高的结合亲和力。本发明还提供了使用这些
多肽的方法。
