MedKoo CAT#: 317562

CAS#: 5786-21-0 (free base)

Description: Clozapine is an atypical antipsychotic drug because it binds to serotonin as well as dopamine receptors. Clozapine is a partial agonist at the 5-HT1A subunit of the serotonin receptor, putatively improving depression, anxiety, and the negative cognitive symptoms associated with schizophrenia. A direct interaction of clozapine with the GABAB receptor has also been shown. GABAB receptor-deficient mice exhibit increased extracellular dopamine levels and altered locomotor behaviour equivalent to that in schizophrenia animal models.

Product Data:
Biological target: Clozapine is a potent antagonist of dopamine and a number of other receptors, with a Ki of 9.5 nM for muscarinic M1 receptor.
In vitro activity: Clozapine binding affected fibrin formation by reducing coagulation speed and thickness of fibrin fibers suggesting that in the presence of clozapine, fibrinogen may acquire thrombogenic characteristics. ORAC and HORAC assays showed that clozapine reduced free radical-induced oxidation of fibrinogen. Reference: Int J Biol Macromol. 2020 Jul 1;154:142-149. https://pubmed.ncbi.nlm.nih.gov/32184141/
In vivo activity: While control animals treated with vehicle showed marked signs of EAE with a mean score of 4.3 ± 0.7 at the peak of EAE and chronification over more than 50 d, clozapine led to a dose-dependent reduction of clinical signs (Figure 2B). Disease incidence declined dose-dependently following clozapine administration (Additional Table 3). Moreover, the onset of clinical signs was delayed by 3 d in 15 mg/kg treated mice.
