OSU-03012 (AR-12) is an inhibitor of 3-phosphoinositide-dependent kinase-1 (PDK-1) with IC50 value of 5μm, which shows 2-fold higher potency over OSU-02067 [1].

OSU-03012 has represented to suppress PC-3 cell proliferation and induce apoptosis in PC-3 cells. Expression of the constitutively active forms of PDK-1 and Akt has revealed to reduce OSU-03012-induced apoptosis in PC-3 cell [1].

OSU-03012 could potently inhibit the growth of primary human VS cells and malignant schwannoma HMS-97 cells in a dose-dependent manner. In contrast, normal human Schwann cells showed to be more resistant to OSU-03012. Additionally, OSU-03012 revealed to inhibit phosphorylation of AKT at the threonine-308 site in both VS cells and HMS-97 cells [2].
