  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.

  Eight possible diastereomers of the 3-amino-5,6,7-trihydroxy octadecanoic acid (ATHOD) moiety of the burkholdines (Bks) have been synthesized and their configurations assigned. Though the relative configuration of the triol in the ATHOD residue of the Bks was proposed to be anti–anti–anti in the literature, 1H NMR spectra of our synthesized anti–anti–anti ATHOD derivative was inconsistent with that

  已经合成了伯克霍尔定 (Bks) 的 3-氨基-5,6,7-三羟基十八烷酸 (ATHOD) 部分的八种可能的非对映异构体，并分配了它们的构型。虽然在文献中提出 Bks 的 ATHOD 残基中三醇的相对构型是反抗反抗的，但我们合成的反抗反抗的1 H NMR 光谱ATHOD 衍生物与分离的 ATHOD 残基的衍生物不一致，表明文献中对该残基的相对构型的分配是不正确的。然而，通过使用 Kishi 的 NMR 数据库方法将我们的 ATHOD 衍生物的 NMR 数据与配置定义的 2-氨基-4-戊醇样品的 NMR 数据进行比较，我们得出结论 ATHOD 部分的绝对构型为 (3 R ,5 S , 6 R ,7 S )。此外，我们发现存在于 occidiofungins A-D 中的 ATHOD 残基具有与所有 Bks 中相同的构型。

  Negamycin 1 is a bactericidal antibiotic with activity against Gram-negative bacteria, and served as a template in an antibiotic discovery program. An orthogonally protected beta-amino acid derivative 3a was synthesized and used in parallel synthesis of negamycin derivatives on solid support. This advanced intermediate was also used for N- and C-terminal modifications using solution-phase methodologies. The N-terminal modifications have resulted in the identification of active analogues, whereas the C-terminal modifications resulted in complete loss of antibacterial activity. The N-methyl negamycin analogue, 19a, inhibits protein synthesis (IC50 = 2.3 muM), has antibacterial activity (Escherichia coli, MIC = 16 mug/mL), and is efficacious in an E. coli murine septicemia model (ED50 = 16.3 mg/kg).

• Peptidyl β-homo-aspartals: Specific inhibitors of interleukin-1β converting enzyme and its homologues (caspases)

  Inhibition of interleukin-1 beta converting enzyme (ICE), apopain, papain, thrombin and trypsin with substrate like peptidyl L- and D-alpha-aldehydes and their L-beta-homo-aldehyde analogues was investigated. The L-beta-homo-aspartals appear to be specific inhibitors for ICE and its homologues; the other enzymes were not inhibited with such L-beta-homo aldehydes. Papain shows tolerance for D-residues at P-1 depending on their chiral stability. (C) 1998 Elsevier Science Ltd. All rights reserved.
