Competitive PTP1B inhibitor (IC50 = 0.781 μM). Binds catalytic P-loop of enzyme. Improves insulin sensitivity in obese mice in the glucose tolerance test and the homeostasis model assessment of insulin resistance index (HOMA-IR). Enhances insulin-induced glucose uptake in adipocytes and myotubes in vitro. Exhibits some selectivity for PTP1B over other protein tyrosine phosphatases, except TCPTP.
