FAPI-46 是一种基于喹啉的靶向成纤维细胞活化蛋白 (FAP) 的放射性示踪剂。FAPI-46 具有更高的肿瘤吸收率和增长的肿瘤积累时间。FAPI-46 可用于多种不同癌症的肿瘤成像。
FAPI-46 is a quinoline-based fibroblast activation protein (FAP)-targeted radiotracer. FAPI-46 has higher tumor uptake and prolonged tumor accumulation. FAPI-46 can be used for tumor imaging of a multitude of different cancers[1][2].
FAPI-46 (1-24 h) robustly binds to human FAP in human FAP-expressing HT-1080 cells[1].
FAPI-46 (i.v.) shows improved ratios of tumor to liver, kidney, and brain uptake, resulting in an enhanced image contrast for PET imaging[1].
