Cathepsin K complexed with a cyanamide-based inhibitor
Structural highlights
DiseaseCATK_HUMAN Defects in CTSK are the cause of pycnodysostosis (PKND) [MIM:265800. PKND is an autosomal recessive osteochondrodysplasia characterized by osteosclerosis and short stature.[1] [2] [3] [4] FunctionCATK_HUMAN Closely involved in osteoclastic bone resorption and may participate partially in the disorder of bone remodeling. Displays potent endoprotease activity against fibrinogen at acid pH. May play an important role in extracellular matrix degradation. Evolutionary Conservation Check, as determined by ConSurfDB.

Publication Abstract from PubMedConversion of the proline-derived cyanamide lead to an acyclic cyanamide capable of forming an additional hydrogen bond with cathepsin K resulted in a large increase in inhibitory activity. An X-ray structure of a co-crystal of a cyanamide with cathepsin K confirmed the enzyme interaction. Furthermore, a representative acyclic cyanamide inhibitor 6r was able to attenuate bone resorption in the rat calvarial model. Acyclic cyanamide-based inhibitors of cathepsin K.,Barrett DG, Deaton DN, Hassell AM, McFadyen RB, Miller AB, Miller LR, Payne JA, Shewchuk LM, Willard DH Jr, Wright LL Bioorg Med Chem Lett. 2005 Jun 15;15(12):3039-43.
