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 In Vitro FAPI-46 (1-24 h) robustly binds to human FAP in human FAP-expressing HT-1080 cells. MCE has not independently confirmed the accuracy of these methods. They are for reference only. In Vivo FAPI-46 (i.v.) shows improved ratios of tumor to liver, kidney, and brain uptake, resulting in an enhanced image contrast for PET imaging . MCE has not independently confirmed the accuracy of these methods. They are for reference only. Form:Solid IC50& Target:fibroblast activation protein (FAP)
