Clozapine is an atypical antipsychotic medication [1]

Clozapine has been considered an atypical antipsychotic medication because of their therapeutic efficacy in the treatment of schizophrenic patients resistant to conventional neuroleptics. In addition, Clozapine has shown the effect on binding 5HT1c and 5HT2 sites with pKi values of 8.07 and 7.63, respectively. Besides, Clozapine has been reported to recognize all human dopamine receptor subtypes with Ki values of 80nM, 230nM, 89nM, 141nM and 250nM for D2, D3, D4, D1 and D5 receptor, respectively. Clozapine has been found to be the only drug to have a higher affinity for 5-HT1c sites than for the 5-HT2, D1 and D2 receptors [1].

General tipsFor obtaining a higher solubility, please warm the tube at 37°C and shake it in the ultrasonic bath for a while. Stock solution can be stored below -20°C for several months.


Cell experiment:

Cell lines

Prefrontal cortical (PFC) neurons, Rats hepatocytes

Preparation method

The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reacting condition

0.1-10 μM for 16-72 h; or 20 - 80 μM for 48 h


Clozapine induced initial pERK1-specific blockade and subsequent activation of the ERK response in prefrontal cortical (PFC) neurons in vitro [1]. Moreover, Clozapine (20-80 μM) concentration-dependently induced hepatotoxicity [2].

Animal experiment:

Animal models

C57BL/6 mouse model, Male Sprague-Dawley (SD) rats model

Dosage form

1, 2.5 mg/kg; intraperitoneal administration, for 15 h, 24 h; or 25 mg/kg, oral administration, for 7 days


Clozapine induced ERK1/2 cell signaling activation via the EGF receptor in mouse prefrontal cortex [1]. Moreover, Clozapine treatment led to marked accumulation of triglyceride and increase in gglutamyl transpeptidase (g-GT) activity, liver weight, and serum AST in rats [2].

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
