チデグルシブ

It is reported that tideglusib administration inhibits the activation of astrocytes and microglial cells, thus it presented a neuroprotective effect. It is known as well that the inactivation of GSK-3 protects against excitotoxicity. In pre-clinical trials, there have been reports of decrease Tau hyperphosphorylation, lower brain amyloid plaque load, learning and memory enhancement, prevention of neuronal loss and significant increases of the insulin growth factor 1 which is a potent neurotrophic peptide with therapeutic value.The reports in clinical trials have shown a trend in cognition increase of Alzheimer patients treated for 24 weeks.

GSK-3 is a proline/serine protein kinase that is ubiquitously expressed and involved in many cellular signaling pathways. From all its diverse functions, it plays a key role in Alzheimer's disease. This role is related to its link with β-amyloid and tau pathology. It has been suggested that aberrant Wnt or insulin signaling results in increased GSK-3 function. This kinase acts on γ-secretase producing the hyperphosphorylation of tau, the formation of neurofibrillary tangles and senile plaques. Tideglusib inhibits GSK-3 irreversibly by presenting a non-competitive inhibition pattern with respect to ATP. The binding of tideglusib seems to directly relate to the motif containing Cys199.
