Abstract: Osteoarthritis (OA) is an age-related degenerative disease, which is characterized by
chronic joint pain, inflammation and the damage of joint cartilage. At present, steroidal drugs and
nonsteroidal anti-inflammatory drugs (NSAIDS), selective cyclooxygenase-2 (COX-2) inhibitors,
are the first-line drugs for the treatment of OA. However, these drugs could lead to some cardiovascular
side effects. Therefore, it is urgent to develop novel agents for the treatment of OA. Matrix
metalloproteinase-13 (MMP-13), an important member of matrix metalloproteinases (MMPs) family,
plays a vital role by degrading type II collagen in articular cartilage and bone in OA. It is noted
that MMP-13 is specially expressed in the OA patients, and not in normal adults. In addition, broadspectrum
MMP inhibitors could result in some painful and joint-stiffening side effects, called musculoskeletal
syndrome (MSS) in the clinical trials. Thus, developing selective MMP-13 inhibitors is
a potential strategy for the therapy of OA. In this review, we summarize the recent progress of selective
MMP-13 inhibitors including two subfamilies, namely zinc-binding and non-zinc-binding selective
MMP-13 inhibitors.
