| 摘要 |
The invention relates to novel peptides which are biologically active as ligands of blood platelet integrin GPIIbIIIa and the αv integrins, preferably the av&bgr;s and αv&bgr;3 integrin, having the formula (I): R1-Arg-X-Asp-Leu-Asp-Ser-Leu-Arg-R2 (I), in which R1 denotes H, acetyl or acyl and R2 denotes -Oh, OR3NH2, NHR3, N(R3)2 R3 denotes atkyl, aralkyl, aryl, Het and X denotes an amino acid of the formula (II), in which A denotes (CH2)n R4 denotes H, alkyl, aralkyl or aryl, and n denotes 1, 2, 3, 4, 5 or 6, and the amino acid of the formula (II) is bonded to the adjacent Arg via a peptide bond of the α-amino group and to the α-amino group of the adjacent Asp via a peptide bond of the α-carboxyl group.
