PTP1B-IN-1 is primarily used in research settings to study the role of protein tyrosine phosphatase 1B (PTP1B) in cellular processes. It acts as an inhibitor of PTP1B, making it valuable for investigating pathways related to insulin signaling and glucose metabolism. This compound is particularly useful in exploring potential therapeutic strategies for type 2 diabetes and obesity, as PTP1B is known to negatively regulate insulin and leptin signaling. Additionally, PTP1B-IN-1 is employed in cancer research to examine its effects on cell proliferation and survival, given PTP1B's involvement in oncogenic signaling pathways. Its application extends to understanding metabolic disorders and identifying novel drug targets.
