| titleOfInvention | Pancreozymin-cholezystokinin active peptides, process for their preparation and pharmaceutical compositions containing them |
| abstract | Peptides with the carboxyl-terminal sequence of pancreozymin cholecystokinin 25-33, such that amino acid residue 25 carries a strongly basic group, amino acid residue 28 has a hydrophilic character of the hydroxyamino acid type and amino acid residue 31 has a strongly hydrophobic character of the type of amino acids with aliphatic side chains has, in particular nonapeptides of the sequence HX-Asp-Tyr (S0 3 H) - Y-Gly-Trp-Z-Asp-Phe-NH 2 , where X is arginine, homoarginine, norarginine, Ne, N ε- dialkyllysine. N8 or Nδ-dialkylornithine, Y threonine, serine or hydroxy-proline and Z is norleucine, leucine, norvaline or a-aminobutyric acid, have pronounced pancreozymin activity and can be used in drugs for controlling the function of the gallbladder and for controlling the enzyme secretion of the Pancreas.n n n Tyrosine-O-sulphate-barium salt and its N-acyl derivatives can be used as intermediates for the preparation of such peptides to give 27, a N-acyl-tyrosine in a polar organic solvent, with excess pyridine-S0 3 is reacted to introduce the amino acid residue, the resulting Solution extracted with water, the barium salt of N-acyl-tyrosine-O-sulfate falls from the aqueous phase by adding a soluble barium compound, optionally splitting off the acyl group in the usual way and the tyrosine-O-sulfate-barium salt thus obtained or its acyl derivative processed in a manner known per se by customary peptide synthesis methods. |
