A 36-residue peptide corresponding to the entire amino acid sequence of human pancreatic polypeptide (hPP) was synthesized by the solution method. A new Asp derivative, Asp (OMen) [Men = menthyl] was employed. Seven fragments served to construct the peptide backbone of hPP and all the protecting groups employed were cleaved by 2 M trimethylsilyl trifluoromethane-sulfonate-diphenylsulfide/trifluoroacetic acid. The synthetic peptide inhibited protein secretion from rat pancreas.
