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.
Exploration of the P2–P3 SAR of aldehyde cathepsin K inhibitors
摘要:
The synthesis and biological activity of a series of aldehyde inhibitors of cathepsin K are reported. Exploration of the properties of the S-2 and S-3 subsites with a series of carbamate derivatized norleucine aldehydes substituted at the P-2 and P-3 positions afforded analogs with cathepsin K IC(50)s between 600 nM and 130 pM.
