Description

Application

Tofisopam has been used for studying its biochemical mechanisms of actions using drug repositioning strategies.

Biochem/physiol Actions

Ligand for the GABA_A receptor benzodiazepine modulatory site.

Studies have reported that tofisopam functions by blocking PDE4 (phosphodiesterase 4). Furthermore, the S-enantiomer of tofisopam is considered ten times more active than R-enantiomer.

Preparation Note

Tofisopam is soluble in DMSO at approximately 14 mg/ml. However, it is insoluble in water.
