'''CATHEPSIN B COMPLEXED WITH DIPEPTIDYL NITRILE INHIBITOR'''<br />


==Overview==
==Cathepsin B complexed with dipeptidyl nitrile inhibitor==
Cathepsin B is a member of the papain superfamily of cysteine proteases, and has been implicated in the pathology of numerous diseases, including, arthritis and cancer. As part of an effort to identify potent, reversible, inhibitors of this protease, we examined a series of dipeptidyl nitriles, starting with the previously reported Cbz-Phe-NH-CH(2)CN (19, IC(50) = 62, microM). High-resolution X-ray crystallographic data and molecular, modeling were used to optimize the P(1), P(2), and P(3) substituents of, this template. Cathepsin B is unique in its class in that it contains a, carboxylate recognition site in the S(2)' pocket of the active site., Inhibitor potency and selectivity were enhanced by tethering a carboxylate, functionality from the carbon alpha to the nitrile to interact with ...

== Publication Abstract from PubMed ==
Cathepsin B is a member of the papain superfamily of cysteine proteases and has been implicated in the pathology of numerous diseases, including arthritis and cancer. As part of an effort to identify potent, reversible inhibitors of this protease, we examined a series of dipeptidyl nitriles, starting with the previously reported Cbz-Phe-NH-CH(2)CN (19, IC(50) = 62 microM). High-resolution X-ray crystallographic data and molecular modeling were used to optimize the P(1), P(2), and P(3) substituents of this template. Cathepsin B is unique in its class in that it contains a carboxylate recognition site in the S(2)' pocket of the active site. Inhibitor potency and selectivity were enhanced by tethering a carboxylate functionality from the carbon alpha to the nitrile to interact with this region of the enzyme. This resulted in the identification of compound 10, a 7 nM inhibitor of cathepsin B, with excellent selectivity over other cysteine cathepsins.
