Cathepsin K in complex with a selective 2-cyano-pyrimidine inhibitor
Structural highlights
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. Evolutionary Conservation Check, as determined by ConSurfDB.

Publication Abstract from PubMedMorphing structural features of HTS-derived chemotypes led to the discovery of novel 2-cyano-pyrimidine inhibitors of cathepsin K with good pharmacokinetic profiles, for example, compound 20 showed high catK potency (IC(50)=4nM), >580-fold selectivity over catL and catB, and oral bioavailability in the rat of 52%. Design and optimization of a series of novel 2-cyano-pyrimidines as cathepsin K inhibitors.,Rankovic Z, Cai J, Kerr J, Fradera X, Robinson J, Mistry A, Hamilton E, McGarry G, Andrews F, Caulfield W, Cumming I, Dempster M, Waller J, Scullion P, Martin I, Mitchell A, Long C, Baugh M, Westwood P, Kinghorn E, Bruin J, Hamilton W, Uitdehaag J, van Zeeland M, Potin D, Saniere L, Fouquet A, Chevallier F, Deronzier H, Dorleans C, Nicolai E Bioorg Med Chem Lett. 2010 Mar 1;20(5):1524-7.
