FAPI-4 is a potent fibroblast activation protein (FAP) inhibitor for the targeting FAP. FAPI-4 can be used in cancer research. 68Ga-FAPI-4 PET/CT is a promising new diagnostic method for imaging various kinds of cancer, with good tumor-to-background contrast ratios[1][2].
FAPI-4 (Intravenous injection; 30 nmol per mouse; once) shows excellent tumor uptake in BALB/c nu/nu mice[2].
