Tideglusib is under the investigation for the development of treatments for Alzheimer's disease and for progressive supranuclear palsy. It is reported to be a potent anti-inflammatory and neuroprotective that is a non-ATP competitive inhibitor of glycogen synthase kinase 3 (GSK-3). Tideglusib is being developed by the Spanish pharmaceutic company Zeltia group and its current status is withdrawn for the treatment of Alzheimer's disease as of 2012.

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.
Tideglusib was initially formulated for the treatment of Alzheimer and progressive supranuclear palsy. The raising interest for the use of tideglusib comes from the significant upregulation of GSK-3 in the brain in patients with Alzheimer disease. Its function as a degradant of β-catenin, was also important, as it prevents the transcription of cell survival genes. All these factors have directed current research towards this kinase as a potential target. Alzheimer disease is the most prevalent form of dementia. The most accepted hypothesis to explain this disease is related to the presence of amyloid β, which triggers a cascade that will alter the Tau protein and provoke synaptic dysfunction and neuronal death. GSK-3 importance in the tissue repair pathway has also pointed out a novel application for tideglusib. Thus, it is also under the research for the natural repair treatment of deep caries lesions.
