Peptide inhibitors of dengue virus NS3 protease. Part 1: Warhead
摘要:
Substrate-based tetrapeptide inhibitors with various warheads were designed, synthesized, and evaluated against the Dengue virus NS3 protease. Effective inhibition was achieved by peptide inhibitors with electrophilic warheads such as aldehyde, trifluoromethyl ketone, and boronic acid. A boronic acid has the highest affinity, exhibiting a K-i of 43 nM. (c) 2005 Elsevier Ltd. All rights reserved.

[reaction: see text] The Passerinireaction of N-protected amino aldehydes, isonitriles, and TFA using pyridine-type bases proceeds under mild conditions and directly affords alpha-hydroxy-beta-amino amide derivatives in moderate to high yields. These adducts are readily hydrolyzed to alpha-hydroxy-beta-amino carboxylic acids. Application of these key intermediates to concise syntheses of P(1)-alpha-ketoamide

Molecular modeling and topographic considerations of the thrombin-specific sequences Boc-Asp-Pro-Arg-TS or Ac-d-Phe-Pro-Arg-TS (TS = transition state analog electrophilic center) and related scaffolds led to the design of novel P-2-P-4-azapeptidomimetic P-1-argininal and P-1-ketoargininamide derivatives (3a-j). The synthesis and biological activity of these potential serine protease inhibitors are presented. (C) 1997, Elsevier Science Ltd.

Peptidomimetic derivatives featuring a P-1-argininoyl heterocycle were designed. The preparation of two key building blocks containing benzoxazole or benzimidazole rings and their incorporation into thrombin and factor Xa specific sequences is described. The serine protease inhibitory activity of these targets was evaluated. Molecular modeling of two representative structures is presented. (C) 1997 Elsevier Science Ltd.
