Description |
AR-A014418 is an ATP-competitive, and selective GSK3β inhibitor with IC50 and Ki of 104 nM and 38 nM in cell-free assays, without significant inhibition on 26 other kinases tested. |
Features |
Cell-permeable GSK3-selective inhibitor. |

In vitro |
AR-A014418 inhibits tau phosphorylation at a GSK3-specific site (Ser-396) in 3T3 fibroblasts expressing human four-repeat tau protein with IC50 of 2.7 μM, and protects cultured N2A cells from death induced by blocking PI3K/PKB pathway. In hippocampal slices, AR-A014418 inhibits neurodegeneration mediated by beta-amyloid peptide. [1] While in NGP and SH-5Y-SY cells, AR-A014418 reduces neuroendocrine markers and suppresses neuroblastoma cell growth. [2]

In vivo |
In ALS mouse model with the G93A mutant human SOD1, AR-A014418 (0-4 mg/kg, i.p.) delays the onset of symptoms, improves motor activity, slows down disease progression, and postpons the endpoint of the disease. [3] In addition, AR-A014418 produces inhibition effect on acetic acid- and formalin-induced nociception in mice by modulating NMDA and metabotropic receptor signaling as well as TNF-α and IL-1β transmission in the spinal cord.
