Aminopeptidase N inhibitors are primarily used in medical research and therapeutic applications due to their ability to modulate enzyme activity. They are investigated for their potential in cancer treatment, as AP-N is often overexpressed in tumor cells, contributing to angiogenesis and metastasis. By inhibiting this enzyme, these compounds can help restrict tumor growth and spread. Additionally, AP-N inhibitors are explored in the context of inflammatory diseases, as the enzyme plays a role in immune response regulation. They are also studied for their potential in managing hypertension, as AP-N is involved in the breakdown of vasoactive peptides. In drug development, these inhibitors serve as valuable tools for understanding the biological functions of AP-N and its role in various pathological conditions.
