  Synthesis of an analogue of the substance P C-terminal hexapeptide with modification at the glutaminyl and methioninyl residues and increased activity in NK-2 receptor type: Structure-activity relationships

  摘要：

  Analogues of [Orn6]-Sp6-11 have been synthesized in which the Met11 residue is replaced by Hse(CH3), Hse(Bzl), Nva(5-OCH3), Nva(5-OBzl) and Abu. These analogues were tested in 3 in vitro preparations representative of NK-1, NK-2 and NK-3 receptor types. The Hse(Bzl) analogue is 16.6-fold more potent than the parent hexapeptide at the NK-2 receptor and 2.4-fold more potent at the NK-3 receptor. The Nva(5-OCH3) analogues howed weak antagonist activity in NK-2 and NK-3 receptor types, being a full agonist at NK-1. It is concluded from structure-activity correlations that the role of Met11 side chain in substance P is associated with activity and/or efficacy, as appropriate modifications in the side chain may result either in agonists with increased activity compared to the parent hexapeptide or selective agonists or may induce antagonism.

  The octatriacontapeptide corresponding to positions 1 to 38 of human parathyroid hormone (hPTH), a half of the whole molecule, was synthesized by assembling 9 peptide fragments in a conventional manner. Arg (mesitylene-2-sulfonyl), a new arginine derivative bearing an acid-labile protecting group, was employed in combination with a new deprotecting procedure with 1 M trifluoromethanesulfonic acid-thioanisole in TFA. The synthetic peptide exhibited an activity of 1400 IU/mg when assayed by the mouse bone adenyl cyclase activity assay.

  A new porcine gastrointestinal 29-residue peptide, galanin, was synthesized in a satisfactory yield by assembling seven peptide fragments followed by deprotection with 1 M trifluoromethane-sulfonic acid-thioanisole in trifluoroacetic acid. Nin-Mesitylenesulfonyltryptophan was employed to suppress indole alkylation during Na-deprotection. β-Cycloheptylaspartate was employed to suppress base-catalyzed succinimide formation. The synthetic peptide exhibited a powerful contractile activity on rat ileum, but not on guinea pig ileum and caused sustained hyperglycemia in dogs.

  Porcine secretin was synthesized by the trifluoromethanesulfonic acid deprotecting procedure. Release of the biologically important His1-residue from synthetic secretin was noted when the secretin was incubated in an aqueous solution at 37°C under nearly neutral conditions. Apparent autolysis of the N-terminal tetrapeptide, His-Ser-Asp-Gly, was examined by using 5 peptide analogs, and the participation of the β-carboxyl group of Asp and the basic amino acid, His, in this unusual phenomenon was deduced. Hydrolysis of the peptide bonds between Asp-Ser (15-16) and Asp-Gly (3-4) was also noted when the above incubated solution was examined by high performance liquid chromatography.
