Description | Clozapine (HF 1854) is an antipsychotic used to treat schizophrenia. Clozapine is a potent antagonist of dopamine and a number of other receptors, with a Ki of 9.5 nM for M1 receptor. |

Ki: 9.5 nM (M1), 51 nM (α2-adrenoceptor), 75 nM (D2)[1] |
In Vitro | Clozapine shows the unique property of having antipsychotic action but no Parkinson-like motor side effects. The chemical structure of clozapine facilitates a relatively rapid dissociation from D2 receptors. After short-term occupation of D2 receptors, peak neural activity raises synaptic dopamine, which then displaces clozapine. While clozapine also occupies other types of receptors, they may not have a significant role in preventing parkinsonism. Clozapine is very potent at D2 receptor with a Ki of 75 nM. Clozapine is also potent at the α2-adrenoceptor with a Ki value of 51 nM[1]. Clozapine causes paradoxical downregulation of 5-HT2A receptors. Clozapine also binds to 5-HT6 and 5-HT7 receptors with high affnity[2]. |
In Vivo | Head-twitch response is decreased and [3H]ketanserin binding is downregulated in 1, 7, and 14 days after chronic clozapine. 5-HT2A mRNA is reduced 1 day after chronic clozapine. Induction of c-fos, but not egr-1 and egr-2, is rescued 7 days after chronicclozapine[3]. |
Animal Admin | Mice: Mice are treated chronically (21 days) with 25 mg/kg/day clozapine. Experiments are conducted 1, 7, 14, and 21 days after the last clozapine administration. [3H]Ketanserin binding and 5-HT2A mRNA expression are determined in mouse somatosensory cortex. Head-twitch behavior, expression of c-fos, which is induced by all 5-HT2A agonists, and expression of egr-1 and egr-2, which are LSD-like specific, are assayed[3]. |
