BML-267 is a potent and selective PTP1B (protein tyrosine phosphatase 1B) inhibitor (IC50=11 μM)1. A similar N-des-methyl analog has been reported and has been used to probe the mechanism of PTP1B-mediated inhibition of leptin signaling. BML-267 have limited cell permeability. A cell permeable diethyl ester prodrug of BML-267 compound is available.
