Design of small molecule ketoamide-based inhibitors of cathepsin K

Bioorg Med Chem Lett. 2004 Feb 9;14(3):719-22. doi: 10.1016/j.bmcl.2003.11.029.

Abstract

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 I collagen hydrolysis in a surrogate assay of bone resorption.
