Tritiated Peptides. Part 11. Synthesis of 6>-, 11>-, and 6,11>-Somatostatin and the Metabolite 1>-Somatostatin

The syntheses are described of somatostatin labelled with tritium singly in the phenylalanine residues at positions 6 and 11 and doubly at residues 6 and 11 to specific radioactivities of 15.5, 13.8 and 14.1 Cim mol-1, respectively, by reductive deiodination of fully-protected precursors.Cysteine residues were proteced by S-trityl groups and the disulphide bridge was formed by iodine oxidation of the tritiated protected precursors.The purity of the products was assessed by acidic hydrolysis, ion-exchange and high-pressure liquid chromatography, and by enzymic digestion of the products modified by reduction and aminoethylation.The synthesis of the metabolite 1>-somatostatin is described.The syntheses of 6>-, 11>- and 6,11>-somatostatin are described.
