Halogen Replacement on the Lysine Side Chain of Lys-Urea-Glu-Based PSMA Inhibitors Leads to Significant Changes in Targeting Properties

ConclusionsIt was demonstrated that the halogen substituent on the lysine terminal amino group on the Glu-urea-Lys backbone did positively affect the binding of [68Ga]Ga-DOTA-SC691-R to PSMA. The bulkier and less electronegative Br (or I) elements are preferred for structural modifications here.
