Definitions

  • This invention relates to peptide derivatives which are useful as therapeutic agents in the treatment of gastroenterological disorders.
  • Peptide YY is a 36-residue peptide amide isolated originally from porcine intestine, and localized in the endocrine cells of the gastrointestinal tract and pancreas (Tatemoto et al. Proc . Natl . Acad . Sci . 79:2514, 1982) .
  • Peptide YY has N-terminal and C-terminal tyrosine amides; accordingly, these two tyrosines give PYY its name (Y represents the amino acid tyrosine in the peptide nomenclature) .
  • PYY has a number of central and peripheral regulatory roles with its homologous peptide neuropeptide Y (NPY) , which was originally isolated from porcine brain (Tatemoto, Proc . Natl . Acad . Sci . 79:5485, 1982). In contrast with the cellular location of PYY, NPY is present in submucous and myenteric neurons which innervate the mucosal and smooth muscle layers, respectively (Ekblad et al. Neuroscience 20:169, 1987). Both PYY and NPY are believed to inhibit gut motility and blood flow (Laburthe, Trends Endocrinol . Metab .
  • PYY receptor system which exhibits a slightly higher affinity for PYY than NPY has been characterized in rat intestinal epithelia (Laburthe et al. Endocrinology 118:1910, 1986; Laburthe, Trends Endocrinol . Metab . supra) and shown to be negatively coupled to adenylate cyclase (Servin et al. Endocrinology 124:692, 1989). Consistently, PYY exhibited greater antisecretory potency than NPY in voltage clamped preparations of rat small intestine (Cox et al. J . Physiol . supra) , while
  • PYY has been implicated in a number of physiological activities including nutrient uptake (see, e.g., Bilcheik et al. Digestive Disease Week
