  Ketoheterocycle-based inhibitors of cathepsin K: A novel entry into the synthesis of peptidic ketoheterocycles

  摘要：

  Ketoheterocyclic inhibitors of cathepsin K have been disclosed. SAR of potency enhancing P-2-P-3 groups coupled with ketoheterocyclic warheads to provide cathepsin K inhibitors have been described. In addition, a novel route to access alpha-ketothiazoles using a key thioamide functionality has been disclosed. The mild method employed allows for the presence of diverse functional groups, such as amide and carbamate functionalities, commonly found in protease inhibitors that have peptidomimetic scaffolds. This new method should provide a quick entry into functionally diverse protease inhibitors. (c) 2005 Elsevier Ltd. All rights reserved.
