BENZOTHIENYL ANALOGUE OF SOMATOSTATIN, SELECTIVE FOR CERTAIN SOMATOSTATIN RECEPTORS

摘要

The invention relates to a peptide compound having an improved binding affinity to somatostatin receptors, comprising a peptide and a chelating group covalently linked to a free amino group of said peptide, wherein said peptide is or comprises a somatostatin analogue carrying a 3-benzothienylalanine residue in its 3-position. The invention further relates to said peptide compound labelled with a detectable element or with a therapeutic radionuclide, as well as to a diagnostic method and to a method for the therapeutic treatment of tumors, by using the labelled compounds.
