FOLH1 and neoplasm: Three radioligands consisting of a DOTA chelator, the aforementioned linker, the albumin-binding group and a urea-based PSMA binding motif (PSMA-ALB-02, PSMA-ALB-05 and PSMA-ALB-97) were radiolabeled with 177Lu and evaluated against [177Lu]Lu-PSMA-617 in PC-3 PIP tumor bearing mice with all three ligands showing a high tumor-to-blood ratio but still high kidney uptake.
