A 36-residue peptide amide corresponding to the entire amino acid sequence of chicken antral peptide was synthesized by assembling seven peptide fragments via the azide, followed by thioanisole-mediated deprotection with trimethylsilyl bromide and trimethylsilyl trifluoromethanesulfonate in trifluoroacetic acid.The synthetic peptide stimulated gastric secretion, but not pancreatic secretion.
