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.

Design of small molecule ketoamide-based inhibitors of cathepsin K
摘要:
A novel series of ketoamide-based inhibitors of cathepsin K has been identified. Modifications to p(2) and p(3) elements were crucial to enhancing inhibitory activity. Although not optimized, a selected inhibitor was effective in attenuating type 1 collagen hydrolysis in a surrogate assay of bone resorption. (C) 2003 Elsevier Ltd. All rights reserved.
