Target complexes based onNOTA/NODAGA/DOTA/DODAGA also showed high affinity and selectivity for GRPR (Gastrin-Releasing Peptide Receptor), SSTR2 (Somatostatin Receptor Subtype 2) and MC1R (Melanocortin-subtype 1 receptor), receptors present on the surface of primary and secondary tumors of the prostate, mammary glands, pancreas, lungs, etc. [48]. This evidence concerns the gene GRPR and prostate neoplasm.
