  Evaluation of synthetic acridones and 4-quinolinones as potent inhibitors of cathepsins L and V

  摘要：

  Cathepsins, also known as lysosomal cysteine peptidases, are members of the papain-like peptidase family, involved in different physiological processes. In addition, cathepsins are implicated in many pathological conditions. This report describes the synthesis and evaluation of a series of N-arylanthranilic acids, acridones, and 4-quinolinones as inhibitors of cathepsins V and L The kinetics revealed that compounds of the classes of acridones are reversible competitive inhibitors of the target enzyme with affinities in the low micromolar range. They represent promising lead candidates for the discovery of novel competitive cathepsin inhibitors with enhanced selectivity and potency. On the other hand, 4-quinolinones were noncompetitive inhibitors and N-arylanthranilic acids were uncompetitive inhibitors. (C) 2012 Elsevier Masson SAS. All rights reserved.

  4-(1H)-quinolones play an important role in medicinal chemistry. Many 2-aryl(alkyl)-4(1H)-quinolones are found to exhibit diverse biological properties. While traditional methods have inherent issues [like starting materials with incompatible functional groups (NH2 and keto groups)], many modern methods either require activated starting materials (like Ynones) or employ expensive metals (Pd, Rh, Au

  开发了一种新型铜催化串联 C-N 和 C-C 键形成反应来制备 2-取代-4-( 1H )-喹诺酮类药物。 4-( 1H )-喹诺酮类药物在药物化学中发挥着重要作用。发现许多2-芳基(烷基)-4( 1H )-喹诺酮类药物表现出多种生物学特性。虽然传统方法存在固有问题（例如具有不相容官能团（NH 2和酮基）的起始材料），但许多现代方法要么需要活化的起始材料（如 Ynones），要么使用昂贵的金属（Pd、Rh、Au 等），其中涉及使用CO或金属络合物进行羰基化。我们的方案提出了一种环保的一步法，使用廉价的 Cu-，从容易获得的芳基硼酸（或频那醇酯）和腈作为新原材料构建这些有用的 2-取代-4-( 1H )-喹诺酮类。催化剂和O 2 (空气)作为绿色氧化剂。我们进一步将其应用扩展到各种天然产物的合成，包括首次正式全合成普那那文。已经提出了一种可能的机制，涉及芳基腈离子（由于芳基硼物质和腈基之间的分子间
