Peptide analogues of the C-terminal tetrapeptide of gastrin in which the phenylalanine had been replaced were synthesized and their biological activity on acid secretion evaluated. Compounds Boc-Trp-Leu-Asp phenylethylamide 6, Boc-beta-Ala-Trp-Leu-Asp phenylethylamide 9, Boc-Trp-Leu-Asp p-fluorophenylethylamide 19, Boc-Trp-psi(CH2NH)-Leu-Asp phenylethylamide 23, Boc-Trp-Leu-Asp 2,2-diphenylethylamide 15, and Boc-D Trp-Leu-Asp 2,2-diphenylethylamide 21, in which the phenylalanine had been replaced by phenylethylamine, p-fluorophenylethylamine or 2,2-diphenylethylamine were synthesized. None of these derivatives showed activity on acid secretion in the anaesthetized rat at doses as high as 5 mg/kg. However, they were potent inhibitors of gastrin-induced acid secretion, with ED50 varying from 0.1 to 0.6 mg/kg.
