Used as a selective inhibitor of protein tyrosine phosphatases, particularly PTP1B, making it a valuable tool in biochemical research for studying signal transduction pathways. It helps in understanding cellular processes such as cell growth, differentiation, and insulin signaling. Due to its ability to enhance tyrosine phosphorylation, it is employed in experiments aimed at modulating immune responses and investigating cancer mechanisms. Also utilized in neuroscience research for its effects on neuronal development and synaptic plasticity. Commonly applied in vitro in cell culture studies to probe phosphatase-dependent pathways.
