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,包括至少一个结合KDR或VEGF/KDR复合物的结合基团,其在治疗、检测、分离或定位血管生成有优势的各种用途。特别公开了合成、分离的多肽,能够与KDR或VEGF/KDR复合物高亲和力结合(例如,具有KD<1微米),以及包含这些多肽的二聚体和多聚体构造,特别是对比剂。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过度增殖相关的疾病的治疗方案的治疗效果的方法,例如癌症。
