== Disease ==
[https://www.uniprot.org/uniprot/CATK_HUMAN CATK_HUMAN] Defects in CTSK are the cause of pycnodysostosis (PKND) [MIM:[https://omim.org/entry/265800 265800]. PKND is an autosomal recessive osteochondrodysplasia characterized by osteosclerosis and short stature.<ref>PMID:8703060</ref> <ref>PMID:9529353</ref> <ref>PMID:10491211</ref> <ref>PMID:10878663</ref> 
== Function ==
[https://www.uniprot.org/uniprot/CATK_HUMAN CATK_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.

== Publication Abstract from PubMed ==
The trifluoromethylphenyl P2 motif from previously reported heteroarylnitrile series has been successfully applied for the design and synthesis of highly potent novel ketoamide-based cathepsin S inhibitors. The key in this process is the change of the torsion angle between the P2 phenyl ring and the attached secondary amide by adding a small Cl, F, or Me group at the 2-position.
