Enhanced contrast in FAP-targeting PET imaging with 61Cu-labeled FAP inhibitors: development and preclinical evaluation of novel [61Cu]Cu-Kalios PET radioligands Open
Kalios ligands represent a new class of FAP-targeting 61Cu-labeled radioligands. The half-life of 61Cu allowed delayed 4-h imaging with improved tumor-to-background ratios. The improved delayed imaging and greater dis…

Pyridyl-Ala in the third position of radiolabeled somatostatin antagonists: the effect of regioisomeric substitution Open
Our study revealed that the replacement of Tyr3 with Pal3 isomers does not impact on SST2 affinity, but chirality at this position is critical, as the D2Pal3 derivative loses binding. More intere…

Copper-61 is an advantageous alternative to gallium-68 for PET imaging of somatostatin receptor-expressing tumors: a head-to-head comparative preclinical study Open
Background Gallium-68 positron emission tomography ( 68 Ga-PET) with the two registered somatostatin analogs, [ 68 Ga]Ga-DOTA-Tyr 3 -octreotide ([ 68 Ga]Ga-DOTA-TOC) and [ 68 Ga]Ga-DOTA-Tyr 3 -octreotate ([ 68 Ga]Ga-DOTA-TATE), where DOTA …

<sup>61</sup>Cu-PSMA–Targeted PET for Prostate Cancer: From Radiotracer Development to First-in-Human Imaging Open
The demand for PET tracers that target prostate-specific membrane antigen (PSMA) continues to increase. Meeting this demand with approved 68Ga- and 18F-labeled PSMA tracers is challenging outside of major urban center…

Pharmacokinetics and Biodistribution of Rhopalurus junceus Scorpion Venom in Tumor-Bearing Mice after Intravenous and Oral Administration Open
The PK and BD of R. junceus venom in mice depend on the administration route. These data represent a starting point for future experiments with this scorpion venom in experimental models of cancer.
