應用
Tofisopam has been used for studying its biochemical mechanisms of actions using drug repositioning strategies.
生化／生理作用
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.
準備報告
Tofisopam is soluble in DMSO at approximately 14 mg/ml. However, it is insoluble in water.

Homophthalazines (2,3-benzodiazepin-derivates, such as tofisopam, nerisopam, girisopam) constitute a drug family with strong anxiolytic and antipsychotic potencies. By autoradiography, all of these drugs showed a specific distribution pattern of binding sites exclusively in brain areas which relate to the striato-pallido-nigral

Paroxysmal supraventricular tachycardia (PSVT) is a reentrant tachycardia, and the autonomic nervous system influences the paroxysms of PSVT. Tofisopam (Grandaxin) is a derivative of benzodiazepines. It is reported that heart rate variability (HRV) reveals the function of the autonomic nervous

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
