摘要

报道了一种基于肽的,缺氧诱导因子-1α (HIF-1α)特异性PET示踪剂用于肿瘤缺氧成像。采用快速Al18F标记法制备,稳定性高。Al18F-CLLFVY以高亲和力特异性结合HIF-1α,并在缺氧条件下的细胞中表现出更高的摄取。Al18F-CLLFVY表现出与18F-FMISO相当的肿瘤摄取和更好的对比。

A peptide-based, hypoxia-inducible factor-1 α (HIF-1α) specific PET tracer for tumor hypoxia imaging is reported. It was prepared with a rapid Al18F labeling method with high stability. Al18F-CLLFVY specifically binds to HIF-1α with high affinity and shows higher uptake in cells under hypoxia. Al18F-CLLFVY demonstrated comparable tumor uptake to 18F-FMISO and better contrast.
