Anti-inflammatory properties of MMP inhibitors in experimental models of chronic obstructive pulmonary disease and lung inflammation

Matrix metalloproteinases (MMPs) are a group of proteases known to regulate the turnover of extracellular matrix and thus are suggested to be important in the process of lung disease associated with tissue remodelling. Furthermore, the concept that modulation of airway remodelling including excessive proteolysis damage of the tissue, may be of interest as a basis for future treatment. Among the metalloproteinases (MMPs) family, macrophage elastase (MMP-12) is able to degrade extracellular matrix components such as elastin and is involved in tissue remodelling processes in chronic obstructive pulmonary disease including emphysema. Recent studies using broad spectrum MMP or dual MMP-9/MMP-12 inhibitors have demonstrated a reduction in both inflammatory process and airspace enlargement in lung tissue. In the present chapter, we also report the inhibitory activity of a new MMP-9/MMP-12 inhibitor, AS112108, on acute lung inflammatory processes induced by cigarette smoke.
