CL-82198 is a selective inhibitor of MMP-13. CL-82198 binds to the entire S1’ pocket of MMP-13, which is the basis for its selectivity towards MMP-13 and the lack of inhibitory activities against other MMPs^[1][2]. CL-82198 is a pharmacologic treatment for preventing osteoarthritis (OA) progression^[4].

CL-82198 (10 μM; 24 hours) significantly reduces LS174 cell migration^[1].
CL-82198 decreases CTGF and TGF-β1 protein levels in hepatic stellate cells^[3].
