In vitro
Tideglusib irreversibly inhibits GSK-3, reduces tau phosphorylation, and prevents apoptotic death in human neuroblastoma cells and murineprimary neurons. Tideglusib (2.5 μM) inhibits glutamate-induced glial activation as evidenced by decreased TNF-α and COX-2 expression in rat primary astrocyte or microglial cultures. Tideglusib (2.5 μM) also exerts a potent neuroprotective effect on cortical neurons from glutamate-induced excitotoxicity as evidenced by significant reduction in the number of Annexin-V-positive cells in rat primary astrocyte or microglial cultures.
In vivo
Tideglusib (50 mg/kg) injected into the adult male Wistar rats hippocampus dramatically reduces kainic acid-induced inflammation and has a neuroprotective effect in the damaged areas of the hippocampus.Tideglusib (200 mg/kg, oral) results in lower levels of tau phosphorylation, decreased amyloid deposition and plaque-associated astrocytic proliferation, protection of neurons in the entorhinal cortex and CA1 hippocampal subfield against cell death, and prevention of memory deficits in APP/tau double transgenic mice.
