FAPI-4

FAPI-4/CAS.2374782-02-0 is a quinoline-based theranostic ligands for the targeting of Fibroblast Activation Protein. FAPI-4 was identified as the most promising tracer for clinical application. Compared with the previously published ligand, FAPI-4 showed excellent stability in human serum, higher affinity for FAP as opposed to CD26, and slower excretion in vitro. FAPI-4 represents a promising tracer for both diagnostic imaging and, possibly, targeted therapy of malignant tumors with a high content of activated fibroblasts, such as breast cancer.
