Clozapine  (Synonyms: HF 1854)

Cat. No.: HY-14539 Purity: 99.99%
COA Handling Instructions

Clozapine (HF 1854) is an antipsychotic used for the research of schizophrenia. Clozapine has high affinity for a number of neuroreceptors. Clozapine is a potent antagonist of dopamine D2 with a Ki of 75 nM. Clozapine inhibits the muscarinic M1 receptor and serotonin 5HT2A receptor with Kis of 9.5 nM and 4 nM, respectively. Clozapine is also a potent and selective agonist at the muscarinic M4 receptor (EC50=11 nM).

For research use only. We do not sell to patients.

Description

Clozapine (HF 1854) is an antipsychotic used for the research of schizophrenia. Clozapine has high affinity for a number of neuroreceptors. Clozapine is a potent antagonist of dopamine D2 with a Ki of 75 nM. Clozapine inhibits the muscarinic M1 receptor and serotonin 5HT2A receptor with Kis of 9.5 nM and 4 nM, respectively[1][2][3]. Clozapine is also a potent and selective agonist at the muscarinic M4 receptor (EC50=11 nM)[4].

In Vitro

Clozapine (HF 1854) is a D2 receptor antagonist with a Ki of 75 nM, blocks the serotonin 5HT2A receptor with a Ki of 4 nM, inhibits the muscarinic M1 receptor with a Ki of 9.5 nM, blocks α2-adrenoceptor with a Ki value of 51 nM[1].
? Clozapine (0-1 μM; 24 h) downregulates 5-HT6 and upregulates 5-HT7 receptors in HeLa cells[2].
? Clozapine is a full agonist at the muscarinic M4 receptor (EC50=11 nM) expressed in CHO cells[4].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
