Structural formula of the radiohybrid PSMA-targeted ligand [18F]Ga-rhPSMA-7 equipped with a Silicon-Fluoride Acceptor for 18F-labeling in an isotopic exchange reaction. [18F]Ga-rhPSMA-7 represents a mixture of four stereoisomers (7.1, 7.2, 7.3, 7.4), differing in the stereoconfiguration of the diaminopropionic acid branching unit (D-Dap or L-Dap) and the glutamic acid pendant arm at the DOTA-GA-chelator (R-DOTA-GA or S-DOTA-GA; DOTA-GA: 2-(4,7,10-tris(carboxymethyl)-1,4,7,10-tetraazacyclododecan-1-yl)pentanedioic acid)
