The present invention provides polypeptides, peptide dimers, and multimeric complexes comprising at least one binding moiety for KDR or VEGF/KDR complex, which have a variety of uses wherever treating, detecting, isolating or localizing angiogenesis is advantageous. Particularly disclosed are synthetic, isolated polypeptides capable of binding KDR or VEGF/KDR complex with high affinity (e.g., having a K
D
<1
μM), and dimer and multimeric constructs comprising these polypeptides, particularly contrast agents. Also provided are methods for monitoring and evaluating the therapeutic effectiveness of treatment protocols for diseases associated with angiogenesis or endothelial cell hyperproliferation, such as cancer, using contrast agents of the invention.
本发明提供了多肽、肽二聚体和多聚复合物,其中包括至少一种结合KDR或VEGF/KDR复合物的结合基团,这些复合物在治疗、检测、分离或定位血管生成有优势的任何地方都有各种用途。特别公开的是能够高亲和力地结合KDR或VEGF/KDR复合物(例如,具有KD<1μM)的合成、分离的多肽,以及包含这些多肽的二聚体和多聚体构造,特别是对比剂。本发明还提供了使用本发明的对比剂监测和评估与血管生成或内皮细胞增殖过度相关的疾病治疗方案的治疗效果的方法,例如癌症。
