Biological Activity

Description Tideglusib (NP031112, NP-12) is an irreversible, non ATP-competitive GSK-3β inhibitor with IC50 of 60 nM in a cell-free assay; fails to inhibit kinases with a Cys homologous to Cys-199 located in the active site. Phase 2.
Targets
GSK-3β [1]
(Cell-free assay)
60 nM
In vitro Tideglusib irreversibly inhibits GSK-3, reduces tau phosphorylation, and prevents apoptotic death in human neuroblastoma cells and murineprimary neurons. [1] 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. [2]
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. [2] 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.

Protocol (Only for Reference)

Kinase Assay: [1]
Binding Experiments with Radiolabeled Tideglusib [35S]Tideglusib (207 Bq/nmol) at 55 μM is incubated with 5 μM GSK-3β for 1 h at 25 °C in 315 μL of 50 mM Tris-HCl, pH 7.5, containing 150 mM NaCl and 0.1 mM EGTA. The incubation is extended for another 30 min after having added 35 μL of the same buffer with or without 100 mM DTE. Finally, a third 40-μL aliquot of each original sample is mixed with 10 μL of denaturing electrophoresis sample buffer without reducing agents, and 35 μL of this mixture is loaded onto a 10% polyacrylamide gel and subjected to SDS-PAGE, followed by fluorography of the dried gel.
Animal Study: [3]
Animal Models Transgenic APPsw-tauvlw mice overexpressing human mutant APP and a triple human tau mutation.
Dosages 200 mg/kg
Administration Oral gavage

(A) NPCs were treated with 3µM of the GSK3 inhibitor (tideglusib) for 24 hours. Representative images of untreated SPG11-NPCs (SPG11‐NT) and tideglusib-treated SPG11-NPCs (SPG11-Tide) on day 3. Cell proliferation was analyzed using colabeling of PCNA in Nestin/Sox2-positive NPCs. Nuclei were visualized with DAPI. Scale bar = 50µm. (B) Increased numbers of Nestin/Sox2‐positive cells colabeled with PCNA in CHIR99021-treated SPG11-NPCs. (C) Tideglusib-treated SPG11-NPCs, compared to untreated NPCs, revealed restoration of cell proliferation similar to the CTRL‐NPCs.

Data from [Data independently produced by , , Front Immunol, 2018, 9:2527]

BV-2 cells were pretreated with NP-12 (an inhibitor of GSK-3β, 2.5 μM) for 4 h, following which they were treated with PLD for 1 h. After cells were harvested, the protein expression of GSK-3β, p-GSK-3βSer9 (D), and Nucleosol-Nrf2 (E) was measured via Western blotting.
