title: Synthesis of porcine neuropeptide Y(NPY) in solution.
abstract: The porcine neuropeptide Y (NPY), a 36-residue peptide amide, was synthesized by assembling six peptide fragments followed by thioanisole-mediated deprotection with trifluoromethanesulfonic acid in trifluoroacetic acid. beta-Cycloheptyl aspartate, Asp(OChp), was employed to suppress base-catalyzed succinimide formation. When administered to dogs, the purified peptide (10 micrograms/kg) caused prolonged increase of systemic arterial blood pressure and decreased pancreatic blood flow.
