  Synthesis of gastrin antagonists, analogs of the C-terminal tetrapeptide of gastrin, by introduction of a .beta.-homo residue

  摘要：

  A series of analogues of Boc-Trp-Leu-Asp-Phe-NH2, a potent gastrin agonist, were synthesized by introducing a beta-homo residue in the sequence. These compounds were tested in vivo on acid secretion, in the anesthetized rat, and for their ability to inhibit binding of labeled gastrin to its receptors on gastric mucosal cells. These analogues behaved as gastrin antagonists. The most potent compounds in this series were Boc-Trp-Leu-beta-homo-Asp-NHCH2C6H5 (10) (IC50 = 1 microM, ED50 = 0.2 mg/kg), Boc-Trp-Leu-beta-homo-Asp-NHCH2CH2C6H5 (11) (IC50 = 0.75 microM, ED50 = 0.5 mg/kg), Boc-Trp-Leu-beta-homo-Asp-Phe-NH2 (12) (IC50 = 1.5 microM, ED50 = 0.1 mg/kg), and Boc-Trp-Leu-beta-homo-Asp-D-Phe-NH2 (13) (IC50 = 2 microM, ED50 = 0.1 mg/kg). We could demonstrate the importance of the region of the peptide bond between leucine and aspartic acid and of the structure of the C-terminal dipeptide Asp-Phe-NH2, for exhibiting biological activity on acid secretion.

  synthetic equivalents of a variety of α‐carboxylate anions. Phase‐transfer catalysis (PTC) enabled their mild deprotonation and catalytic asymmetric addition to highly reactive imines generated in situ from α‐amidosulfones (see scheme; Pg=protecting group). The synthetic utility of the products was demonstrated by their straightforward transformation into a range of β‐amino acid derivatives.
