  Synthesis and biological activity of new peptide segments of gastrin exhibiting gastrin antagonist property

  摘要：

  A series of C-terminal peptide segments of gastrin, i.e., (tert-butyloxycarbonyl)-L-tryptophyl-L-methionyl-L-aspartic acid amide, (tert-butyloxycarbonyl)-glycyl-L-tryptophyl-L-methionyl-L-aspartic acid amide, (tert-butyloxy-carbonyl)-L-tyrosyl-glycyl-L-tryptophyl-L-methionyl-L-asp artic acid amide, and (benzyloxycarbonyl)-L-glutamyl-L-alanyl-L-tyrosyl-glycyl-L-tryptophyl-L -methionyl-L-aspartic acid amide were prepared and were shown to competitively inhibit the binding of labeled human gastrin to its receptors in an isolated gastric mucosal cell preparation and to antagonize the action of gastrin on gastric acid secretion (ED50 from 1.5 to 7 mg/kg) in vivo in the reperfused rat stomach, determined according to the method of Ghosh and Schild. From these studies, it could be concluded that the C-terminal phenylalanine residue, which is of primary importance for intrinsic biological gastrin-like activity, is not essential for binding to gastrin receptors.

  Structure-activity relationships of C-terminal tri- and tetrapeptide fragments that inhibit gastrin activity

  摘要：

  A series of tri- and tetrapeptide derivatives, analogues of the gastrin C-terminal region with no phenylalanine residue, were synthesized. These peptides were tested for their ability to inhibit gastrin-stimulated acid secretion in vivo as well as binding of [125I]-(Nle11)-HG-13 to gastric mucosal cell receptors in vitro. Most of the peptides tested exhibited gastrin antagonist activity in vivo and in vitro. Most active derivatives were 20-30 times more potent than the well-known gastrin antagonist derivatives proglumide and benzotript and had 20-200 times more binding affinity. The smallest fragment exhibiting antagonist activity was the tripeptide Boc-L-tryptophyl-L-methionyl-L-aspartic acid amide.
