mAChRs (muscarinic acetylcholine receptors) are acetylcholine receptors that form G protein-receptor complexes in the cell membranes of certainneurons and other cells. They play several roles, including acting as the main end-receptor stimulated by acetylcholine released from postganglionic fibersin the parasympathetic nervous system. mAChRs are named as such because they are more sensitive to muscarine than to nicotine. Their counterparts are nicotinic acetylcholine receptors (nAChRs), receptor ion channels that are also important in the autonomic nervous system. Many drugs and other substances (for example pilocarpineand scopolamine) manipulate these two distinct receptors by acting as selective agonists or antagonists. Acetylcholine (ACh) is a neurotransmitter found extensively in the brain and the autonomic ganglia.

  • HY-14539A
    Clozapine hydrochloride
    		Modulator
    Clozapine hydrochloride (HF 1854 hydrochloride) is an antipsychotic used for the research of schizophrenia. Clozapine hydrochloride has high affinity for a number of neuroreceptors. Clozapine hydrochloride is a potent antagonist of dopamine D2 with a Ki of 75 nM. Clozapine hydrochloride inhibits the muscarinic M1 receptor and serotonin 5HT2A receptor with Kis of 9.5 nM and 4 nM, respectively. Clozapine hydrochloride is also a potent and selective agonist at the muscarinic M4 receptor (EC50=11 nM).
