Metalloprotease inhibitors (MPIs) are a class of drugs that inhibit the activity of metalloproteases, a group of enzymes that play a crucial role in various physiological processes, including inflammation, angiogenesis, and tumor growth. Metalloproteases are zinc-dependent enzymes that break down proteins, and their dysregulation has been linked to numerous diseases, such as cancer, arthritis, and neurodegenerative disorders.

MPIs are designed to selectively inhibit specific metalloproteases, thereby modulating their biological functions. They are often used in the treatment of conditions where the uncontrolled activity of metalloproteases contributes to disease progression. For example, in cancer therapy, MPIs can inhibit the activity of matrix metalloproteases (MMPs), which are involved in tumor invasion and metastasis.

MPIs can be classified into several categories based on their chemical structure and mechanism of action. Some common types include hydroxamates, boronic acids, and peptidomimetics. Hydroxamates, such as marimastat and batimastat, are the most well-known MPIs and have been approved for clinical use. Boronic acids, like roxadustat, are another class of MPIs that have shown promise in preclinical studies. Peptidomimetics, such as galardin, are designed to mimic the natural substrate of metalloproteases and inhibit their activity.

The development of MPIs has been driven by the need for more selective and potent inhibitors of metalloproteases. However, the clinical use of MPIs has been limited by their toxicity and the development of resistance. Ongoing research aims to address these challenges and improve the therapeutic potential of MPIs.
