| abstract |
In particular, the present invention relates to a PSMA binding ligand comprising an oligosaccharide building block which comprises a bond being cleavable by alpha-amylase. Typically, this PSMA binding ligand further comprises a PSMA binding motif Q and a chelator residue A, wherein the PSMA binding motif Q and the chelator residue A are preferably linked via at least one linker A-LAQ-Q comprising the oligosaccharide building block, the PSMA binding ligand thus preferably having the structure (I) or a pharmaceutically acceptable salt or solvate thereof |
