  Design, synthesis, activity, and structure of a novel class of matrix metalloproteinase inhibitors containing a heterocyclic P2′-P3′ amide bond isostere

  摘要：

  A novel series of hydroxamate-based inhibitors of matrix metalloproteinases containing benzimidazole and imidazole heterocycles as amide bond isosteres have been prepared. Potent inhibition (in the low nanomolar range) and selectivity (> 100-fold) can be attained with inhibitors containing only one amide bond. X-ray crystal structures of matrilysin (MMP-7) with two different inhibitors bound confirm that imidazole is an excellent amide bond isostere. Copyright (C) 1996 Elsevier Science Ltd

• An efficient one-pot conversion of carboxylic acids into benzimidazoles <i>via</i> an HBTU-promoted methodology
  作者：Leonard Barasa、Sabesan Yoganathan

  日期：——

  Benzimidazole is a privileged, and routinely used pharmacophore in the drug discovery process. Herein, we report a mild, acid-free and one-pot synthesis of indole, alkyl and alpha-amino benzimidazoles through a novel HBTU-promoted methodology. An extensive library of indole-carboxylic acids, alkyl carboxylic acids and N-protected alpha-amino acids has been converted into the corresponding benzimidazoles

  苯并咪唑是药物发现过程中一种特殊且常规使用的药效基团。在此，我们报告了通过 HBTU 推广的新型方法温和、无酸、一锅法合成吲哚、烷基和 α-氨基苯并咪唑。广泛的吲哚羧酸、烷基羧酸和N保护的 α-氨基酸库已被转化为相应的苯并咪唑，产率为 80-99%。由于α-氨基苯并咪唑是非常有用的合成子，可作为化学催化以及药物发现工作的手性配体，因此我们报道的方法提供了通过简单的一锅操作从市售羧酸直接获得该支架的方法。
