Batimastat sodium salt is primarily used in research settings as a potent inhibitor of matrix metalloproteinases (MMPs), which are enzymes involved in the breakdown of extracellular matrix components. Its application is significant in studying cancer progression, as MMPs play a critical role in tumor invasion and metastasis. By inhibiting these enzymes, it helps researchers understand the mechanisms of tumor growth and spread, potentially aiding in the development of therapeutic strategies. Additionally, it is utilized in studies related to angiogenesis, inflammation, and tissue remodeling, providing insights into various pathological processes. Its role in preclinical models makes it a valuable tool for exploring targeted treatments for diseases involving excessive MMP activity.
