  Identification of novel molecular scaffolds for the design of MMP-13 inhibitors: A first round of lead optimization

  摘要：

  Osteoarthritis (OA) is the leading cause of joint pain and disability in middle-aged and elderly patients, and is characterized by progressive loss of articular cartilage. Among the various matrix metalloproteinases (MMPs), MMP-13 is specifically expressed in the cartilage of human OA patients and is not present in normal adult cartilage. Thus. MMP-13-selective inhibitors are promising candidates in ostearthritis therapy. Recently, we designed an N-isopropoxy-arylsulfonamide-based hydroxamate inhibitor, which showed low nanomolar activity and high selectivity for MMP-13. In parallel to further studies aiming to assess the in vivo activity of our compound, we screened the Life Chemicals database through computational docking to seek for novel scaffolds as zinc-chelating non-hydroxamate inhibitors. Experimental evaluation of 20 selected candidate compounds verified five novel leads with IC50 in the low mu M range. These newly discovered inhibitors are structurally unrelated to the ones known so far and provide useful scaffolds to develop compounds with more desirable properties. Finally, a first round of structure-based optimization on lead 1 was accomplished and led to an increase in potency of more than 5 fold. (C) 2011 Elsevier Masson SAS. All rights reserved.
