New precursors with various linkers for the construction of targeted radiopharmaceuticals based on a pharmacophore fragment of the hormone somatostatin, tetrapeptide H-Phe-d-Trp-Lys-Thr-OH, were synthesized. The tetrapeptide was additionally modified by adding 1,3-thiazolidinecarboxylic acid (Thz) and l-proline (Pro) to improve the cytotoxic properties. Synthesis routes were developed and conjugates of peptides with chelators were obtained.
