BVT948
BVT 948 is a non-competitive, cell-permeable inhibitor of protein tyrosine phosphatases (PTPs) with IC50 of 0.09 - 1.7 μM, displaying irreversible inhibition through catalysis of the hydrogen peroxide-dependent oxidation of PTP. BVT 948 enhances insulin signaling in vitro and insulin tolerance in ob/ob mice in vivo.
