IM-12 is a potent inhibitor of GSK-3β with IC50 value of 53 nM [1].
Glycogen synthase kinase-3β (GSK-3β) is a proline-directed serine-threonine kinase and is involved in neuronal cell development, energy metabolism and body pattern formation. Inhibition of GSK-3β can cause β-catenin accumulation.
IM-12 is a potent GSK-3β inhibitor. In ReNcell VM cells, IM-12 significantly increased total β-catenin by 27% and at a concentration of 3 µM increased the β-catenin amount most. In ReNcell VM cells, IM-12 (3 µM) inhibited GSK-3β to a remaining activity of 27 ± 5%. Also, IM-12 significantly increased the cell doubling time to 26.5 ± 0.9 h and significantly inhibited cell proliferation. In ST14A cells, IM-12 caused an accumulation of β-catenin around the nucleus. In ReNcell VM cells transfected with TOPFlash, IM-12 increased TCF-activity. In cells transfected with TOP and pCAGGS-S33Y (a vector containing β-catenin), IM-12 significantly increased TCF-activity by 270%. In ReNcell VM cells, IM-12 significantly increased the level of βIIItub+ cells to 3.7 ± 0.7%, which suggested that IM-12 increased neuronal differentiation [1].

Novel indolylmaleimide acts as GSK-3beta inhibitor in human neural progenitor cells.[Pubmed:20708937]
Bioorg Med Chem. 2010 Sep 15;18(18):6785-95.
The Wnt pathway is involved in cellular processes linked to either proliferation or differentiation. Therefore small molecules offer an attractive opportunity to modulate this pathway, whereas the key enzyme GSK-3beta is of special interest. In this study, non-symmetrically substituted indolylmaleimides have been synthesized and their ability to function as GSK-3beta inhibitors has been investigated in a human neural progenitor cell line. Among the newly synthesized compounds, the substance IM-12 showed a significant activity in several biological tests which was comparable or even outplayed the effects of the known GSK-3beta inhibitor SB-216763. Furthermore the treatment of human neural progenitor cells with IM-12 resulted in an increase of neuronal cells. Therefore we conclude that indolylmaleimides act via the canonical Wnt signalling pathway by inhibition of the key enzyme GSK-3beta.
