hf-1854

Clozapine (HF 1854) is a tricylic dibenzodiazepine, classified as an atypical antipsychotic agent. It binds several types of central nervous system receptors, and displays a unique pharmacological profile. Clozapine is a serotonin antagonist, with strong binding to 5-HT 2A 2C receptor subtype. It also displays strong affinity to several dopaminergic receptors, but shows only weak antagonism at the dopamine D2 receptor, a receptor commonly thought to modulate neuroleptic activity.

Clozapine (HF 1854) dihydrochloride is utilized for researching psychiatric disorders. This compound exhibits high affinity for numerous neuroreceptors and acts as an effective antagonist of dopamine receptors, with a Ki value of 75 nM. Clozapine inhibits the muscarinic M1 receptor and serotonin 5HT2A receptor, with Ki values of 9.5 nM and 4 nM, respectively. Additionally, Clozapine is a selective agonist of the muscarinic M4 receptor (EC50 = 11 nM).
