| 摘 要： | NGR为肿瘤血管特异导向肽，将其与功能肽KV7连接构建成一导向功能多肽NGR-KV7；为研究该多肽与人肿瘤乳癌细胞的相互作用，应用核磁共振技术来探讨该多肽与细胞的作用位点和亲和性；通过1H NMR和T2弛豫谱的分析，推断该多肽分子与人乳癌细胞结合紧密，亲和程度高.

| Abstract: | NRG is a specific peptide with targeting binding affinity to tumor blood vessel.In this study,tumor-targeting functional peptides were constructed by connecting NGR peptide with functional peptides.To study the interaction between the constructed peptides with human breast cancer cell,binding epitope and affinity were measured with NMR spectroscopy.The spectroscopic and relaxation data showed that these peptides can bind to human breast cancer cell with high affinity. |

| Keywords: | NMR interaction T_2 relaxation NGR peptide |
