FOLH1 and neoplasm: Complexes were evaluated on PC3-PIP/PC3-flu xenografts. [TcO]7,11,14 are the best of the series. High and stable PSMA-dependent tumor uptake (26.81 ± 1.9–33.59 ± 3.20% ID/g at 2 h p.i.). High kidney uptake followed by slow washout. High spleen uptake followed by slow elimination Low non-target organ uptake (<2% ID/g at 1 h p.i.) High target-to-non target ratiosClinical translation: No
