The growth hormone-release inhibiting factor (GH-RIF) tetradecapeptide {A figure is presented}, was prepared by the cyclization of a linear, disulfhydryl peptide intermediate by treatment with potassium ferricyanide. The linear peptide was synthesized by an automated solid-phase technique. The cyclic material inhibited the secretion of radioimmunoassayable growth hormone in vitro at doses as low as 0.1 μg. A high molecular weight compound formed during the cyclization reaction and believed to be predominantly dimer also possessed considerable inhibitory activity.
