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.
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.

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. [3]

Protocol (from reference)

Animal Research:[3]
  • Animal Models: Transgenic APPsw-tauvlw mice overexpressing human mutant APP and a triple human tau mutation.
  • Dosages: 200 mg/kg
  • Administration: Oral gavage
  • (Only for Reference)

Solubility (25°C)

In vitro

DMSO 8 mg/mL warmed

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Frequently Asked Questions

Question 1:
I want to deliver S2823 via i.p. injection, can you suggest one?

This compound can be dissolved in 4% DMSO+corn oil at 2.5 mg/ml clearly. This is the highest concentration, since its solubility in DMSO is pretty low.
