Pyrrolo[1,2‐a]quinoxalines: Insulin Mimetics that Exhibit Potent and Selective Inhibition against Protein Tyrosine Phosphatase 1B

The Front Cover shows a C2C12 cell with the inhibitor 4‐benzylpyrrolo[1,2‐a]quinoxaline targeting the α3/α6/α7 tunnel in the Protein Tyrosine Phosphatase 1B (PTP1B) represented as a ribbon diagram. The insulin receptor (clear green) and the glucose transporter (clear yellow) shown at the cell membrane are involved in the glucose uptake by the cell. The inhibition of PTP1B by this molecule and their analogues produces an insulin mimetic effect. This is indicated by red arrows for the glucose molecules (in sticks) crossing the cell membrane to the cytosol. Cover design by Javier García‐Marín.
