Disease

[CATK_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]

Function

[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

Starting from potent aldehyde inhibitors with poor drug properties, derivatization to semicarbazones led to the identification of a series of semicarbazone-based cathepsin K inhibitors with greater solubility and better pharmacokinetic profiles than their parent aldehydes. Furthermore, a representative semicarbazone inhibitor attenuated bone resorption in an ex vivo rat calvarial bone resorption model. However, based on enzyme inhibition comparisons at neutral pH, semicarbazone hydrolysis rates, and 13C NMR experiments, these semicarbazones probably function as prodrugs of aldehydes.

Semicarbazone-based inhibitors of cathepsin K, are they prodrugs for aldehyde inhibitors?,Adkison KK, Barrett DG, Deaton DN, Gampe RT, Hassell AM, Long ST, McFadyen RB, Miller AB, Miller LR, Payne JA, Shewchuk LM, Wells-Knecht KJ, Willard DH Jr, Wright LL Bioorg Med Chem Lett. 2006 Feb 15;16(4):978-83.
