| 中文摘要: |
| RGD肽是一类含有精氨酸-甘氨酸-天冬氨酸(Arg-Gly-Asp)的小分子多肽,与整合素ανβ3受体有高度的选择性和亲和力。RGD肽与整合素ανβ3受体的特异性结合可介导多种病理生理过程的发生,尤其在肿瘤细胞的黏附、转移和肿瘤新生血管生成中起重要作用。因此,整合素ανβ3受体有望成为新型放射性药物的靶点,而放射性核素标记的RGD肽也可能成为潜在的肿瘤受体显像剂而应用于临床。本文对RGD肽类肿瘤靶向受体显像的研究现状及前景进行综述。 |
| 英文摘要: |
| RGD peptide is a group of small molecular polypeptide which contains Arg-Gly-Asp triple amino acids, a highly selective and affinitive receptor of integrin ανβ3. Specific binding of RGD peptide and integrin ανβ3 receptor may mediate variety of pathophysiological processes, inhibiting tumor cell adhesion and tumor cell metastasis, especially tumorous angiogenesis. Integrin ανβ3 receptor is expected to become the new target spot of radioactive substances, while the radioactive nuclide labeled RGD peptides will be a potential tumor imaging agent in clinical. The present recent findings and prospects related to the tumor targeting RGD peptide receptor imaging agent were reviewed in this article. |
