fapi4

FAPI-4 是一种成纤维细胞激活蛋白 (FAP) 抑制剂，是FAPI配体，在原发性肝癌肝细胞癌（HCC）的PET成像中显示出强烈的肝脏摄取作用，常用于 PET 成像，可用于研究癌症。

FAPI-46 is a quinoline-derived radiotracer that specifically targets fibroblast activation protein (FAP). It exhibits enhanced tumor uptake and extended accumulation in tumor tissues, rendering it suitable for diverse cancer imaging applications.

NOTA-FAPI-4 is an analogue of FAPI-4 and a fibroblast activation protein (FAP) inhibitor. NOTA-FAPI-4 is useful in the diagnosis or treatment of a disease characterized by overexpression of fibroblast activation protein (FAP). NOTA-FAPI-4 can be used as a PET tracer for detection of diseases or disorders related to fibroblast activation protein.
