title: PTP1B inhibitor Ertiprotafib is also a potent inhibitor of IkappaB kinase beta (IKK-beta).
abstract: Ertiprotafib was developed as an inhibitor of PTP1B for the treatment of type 2 diabetes. It normalized the plasma glucose and insulin levels in diabetic animal models, and progressed to a phase II clinical trial. Multiple in vivo targets of Ertiprotafib, in addition to PTP1B inhibition, have been suggested. In this study, Ertiprotafib was also shown to be a potent inhibitor of IkappaB kinase beta (IKK-beta), with an IC(50) of 400nM.
