Application

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

Biochem/physiol Actions

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.
Ligand for the GABAA receptor benzodiazepine modulatory site.

Preparation Note

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

1-(3,4-Dimethoxyphenyl)-4-methyl-5-ethyl-7,8-dimethoxy-5H-2,3-benzodiazepine (tofisopam) contains one chiral center, so two enantiomeric forms exist. The ring system of tofisopam possesses two sterically stable boat structures, leading to two distinct conformers for each enantiomer. A method was developed for the separation of these enantiomers
