A structural screening approach to ketoamide-based inhibitors of cathepsin K

Bioorg Med Chem Lett. 2005 May 2;15(9):2209-13. doi: 10.1016/j.bmcl.2005.03.023.

Abstract

Several novel ketoamide-based inhibitors of cathepsin K have been identified. Starting from a modestly potent inhibitor, structural screening of P2 elements led to 100-fold enhancements in inhibitory activity. Modifications to one of these leads resulted in an orally bioavailable cathepsin K inhibitor.
