Used primarily as a selective inhibitor of protein tyrosine phosphatases, particularly PTP1B, making it a valuable tool in biochemical and cellular research. It helps in studying signal transduction pathways involving phosphorylation, especially those related to insulin and leptin signaling. Its ability to enhance tyrosine phosphorylation in cells makes it useful in experiments aiming to understand cell growth, differentiation, and metabolic regulation. Commonly applied in vitro to investigate the role of phosphatase activity in disease models such as diabetes, obesity, and cancer.
