N-(dibenzo[b,d]thiophen-3-ylsulfonyl)-L-valine

N-(dibenzo[b,d]thiophen-3-ylsulfonyl)-L-valine is an experimental small molecule compound belonging to the class of valine derivatives. It acts as a selective inhibitor of macrophage metalloelastase, also known as matrix metalloproteinase 12 (MMP12). Macrophage metalloelastase is involved in tissue injury and remodeling, with significant elastolytic activity. Inhibition of this enzyme has been explored for potential therapeutic applications in diseases involving excessive tissue degradation or inflammation, such as chronic obstructive pulmonary disease (COPD) and asthma. However, there are no approved indications or clinical trials reported for this compound[1][2][3][5].
