muscarinic acetylcholine receptor

Clozapine N-oxide is the major metabolite of Clozapine and is blood-brain barrier permeable. Clozapine N-oxide is an agonist of DREADDs and activates the DREADD receptors hM3Dq and hM4Di. Clozapine N-oxide is also a dopamine antagonist and selective muscarinic M4 receptor agonist.

Ipratropium bromide monohydrate (Ipratropium bromide hydrate) is a muscarinic antagonist structurally related to ATROPINE but often considered safer and more effective for inhalation use. It is used for various bronchial disorders, in rhinitis, and as an antiarrhythmic.

Amitriptyline hydrochloride (Annoyltin) is the hydrochloride salt of the tricyclic dibenzocycloheptadiene amitriptyline with antidepressant and antinociceptive activities.

Pilocarpine Hydrochloride (NSC 5746 HCl) , a nonselective muscarinic acetylcholine receptor agonist, is utilized to produce an experimental model of epilepsy.

Oxybutynin (Ditropan) is a synthetic anticholinergic agent that is used for treatment of urinary incontinence and overactive bladder syndrome.

Pilocarpine nitrate (Pilagan) is a slowly hydrolyzed muscarinic agonist with no nicotinic effects. Pilocarpine is used as a miotic and in the treatment of glaucoma.

Olanzapine (LY170053) is an atypical antipsychotic that is used currently in the treatment of schizophrenia and bipolar illness.

Arecoline hydrobromide (Arecoline HBr) is a muscarinic acetylcholine receptor agonist.

Bethanechol chloride (Carbamyl-β-methylcholine chloride) is a slowly hydrolyzing muscarinic agonist with no nicotinic effects. It is used to increase smooth muscle tone in the GI tract following abdominal surgery or to treat urinary retention without obstruction. Possible side effects include hypotension, heart rate changes, and bronchial spasm.

Prifinium bromide is a quaternary ammon antimuscarinic. It inhibits hyperkinesia of the digestive organs and urinary tract and has a spasmolytic action.

Scopolamine butylbromide ((-)-Scopolamine butylbromide) is a competitive antagonist of mAChR (IC50: 55.3 ± 4.3 nM).

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.

Dronedarone (SR 33589) is an amiodarone analogue which has an effective and promising treatment for Atrial fibrillation.

Atropine (DL-Hyoscyamine) Sulfate is the sulfate salt of atropine, a naturally-occurring alkaloid isolated from the plant Atropa belladonna. Atropine functions as a sympathetic, competitive antagonist of muscarinic cholinergic receptors, thereby abolishing the effects of parasympathetic stimulation.

Atropine sulfate monohydrate (Atropine sulfate hydrate), the sulfate salt of atropine, is a competitive muscarinic acetylcholine receptor antagonist.

L-Hyoscyamine (Daturine) functions as a non-selective, competitive antagonist of muscarinic receptors, thereby inhibiting the parasympathetic activities of acetylcholine on the salivary, bronchial, and sweat glands, as well as the eye, heart, bladder, and gastrointestinal tract. Hyoscyamine is a belladonna alkaloid derivative and the levorotatory form of racemic atropine isolated from the plants Hyoscyamus niger or Atropa belladonna, which exhibits anticholinergic activity. These inhibitory effects cause a decrease in saliva, bronchial mucus, gastric juices, and sweat. Furthermore, its inhibitory action on smooth muscle prevents bladder contraction and decreases gastrointestinal motility.

Tiotropium bromide (BA679 BR) is a long-acting, 24 hour, anticholinergic bronchodilator used in the management of chronic obstructive pulmonary disease (COPD). Tiotropium is a muscarinic receptor antagonist, on topical application it acts mainly on M3 muscarinic receptors located in the airways to produce smooth muscle relaxation, thus producing a bronchodilatory effect.

Otenzepad (AF-DX 116) is a selective M2 mAChR antagonist with IC50 values of 386 nM in rat heart and 640 nM in rabbit peripheral lung.

Procyclidine hydrochloride ((±)-Procyclidine hydrochlorid) is a potent anticholinergic agent and also have NMDA antagonist properties.

Guvacoline hydrochloride (Norarecoline hydrochloride) is a muscarinic agonist.

Arborine (Arborin) is a larval growth inhibitor from glycoslnis pentaphylla.

Anisodamine Hydrobromide (6-Hydroxyhyoscyamine) is an anticholinergic and α1-adrenergic receptor antagonist used in the treatment of acute circulatory shock.

Fesoterodine ((R) Fesoterodine) is an orally active, competitive mAChR antagonist with pKi values of 8.0, 7.7, 7.4, 7.3, 7.5 for M1, M2, M3, M4, M5 receptors, respectively. It is used for the overactive bladder (OAB).

Scopolamine hydrobromide ((-)-Scopolamine hydrobromide) is an alkaloid from SOLANACEAE, especially DATURA and SCOPOLIA. Scopolamine and its quaternary derivatives act as antimuscarinics like ATROPINE, but may have more central nervous system effects. Among the many uses are as an anesthetic premedication, in URINARY INCONTINENCE, in MOTION SICKNESS, as an antispasmodic, and as a mydriatic and cycloplegic.
