muscarinic receptor

Darenzepine is a muscarinic receptor inhibitor.

Anisodamine (6-beta-Hydroxyhyoscyamine) is an antagonist of muscarinic and nicotinic cholinoceptor with similar affinities at the muscarinic receptor as scopolamine and atropine. Anisodamine improve the microcirculation in states of shock and can be used in studies about organophosphate poisoning.

Tiquizium has effective Antimuscarinic effect, and causes significant bronchodilation in patients with chronic obstructive pulmonary disease.

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.

Solifenacin (YM905 free base) (YM905 free base) is a novel muscarinic receptor antagonist, its pKis for M1, M2 and M3 receptors is of 7.6, 6.9 and 8.0, respectively.

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

Hupehenine is a steriodal alkaloid extracted from the bulbs of Fritillaria Hupehensis, with the potential for inhibiting acetylcholine, antagonism for muscarinic receptors and cholinesterase inhibition.

L-Hyoscyamine sulfate (Levsin Sulfate) is the sulfate salt of a belladonna alkaloid derivative and the levorotatory form of racemic atropine isolated from the plants Hyoscyamus niger or Atropa belladonna, which exhibits anticholinergic activity. Hyoscyamine 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. 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.

Guvacoline hydrochloride (Norarecoline hydrochloride) is a muscarinic agonist.

Blarcamesine (AVex-73) is a muscarinic M1 agonist potentially for the treatment of Alzheimer's disease.

BTM-1086 is a potent gastric secretory inhibitor and an anti-ulcer agent.

Orphenadrine is a noncompetitive N-methyl-D-aspartate (NMDA) receptor antagonist that inhibits clonal HERG channels in a concentration-dependent manner, producing an IC of 0.85 μM in HEK cells.Orphenadrine is an antagonist of central and peripheral muscarinic receptors. Attenuation is blocked by mutations in pore residues Y652 or F656. Orphenadrine has antispasmodic, analgesic, and anticholinergic activity and protects against glutamatergic neurotoxicity in vitro and in vivo.Orphenadrine has inhibitory effects on sodium channels and can be used in the treatment of Parkinson's disease.

Xanomeline oxalate (LY246708 oxalate), a potent and selective muscarinic receptor agonist (SMRA), effectively stimulates in vivo phosphoinositide hydrolysis. It is a valuable compound for Alzheimer's disease research.

Scopolamine is a high-affinity (nanomolar level) muscarinic receptor antagonist that can reversibly inhibit 5-HT₃ receptor responses (IC₅₀ = 2.09 μM). It is commonly used to induce animal models of Alzheimer's disease or memory impairment.

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.

(±)-Tazifylline is a selective and long-acting antagonist of histamine H1 receptor. Tazifylline shows much lower affinity for H2 receptors, α- and β-adrenoceptors, 5-hydroxytryptamine and muscarinic receptor subtypes.

Cyclodrine hydrochloride is a dual cholinergic muscarinic receptor (mAChR) and nicotinic receptor (nAChR) antagonist that can be used in the study of neurologically related diseases.

Cyclodrine (Cyclopent) is a cholinergic (muscarinic, nicotinic) (mAChR and nAChR) receptor antagonist.

PQCA is a muscarinic M1 receptor-positive allosteric regulator, which is highly selective and effective. PQCA exhibited EC50 values of 49 nM in rhesus monkey and 135 nM in human M1 receptors, but showed no activity against other muscarinic receptors. PQCA is a potential compound for reducing cognitive deficits associated with Alzheimer's disease.

YM-46303 is a selective and potent muscarinic receptor antagonist that exhibits high affinity for the M3 receptor.YM-46303 can be used to study bradycardia in medullary rats.

CHF5407(SVT-47060) is a potent and selective muscarinic M3 receptor antagonist with prolonged action at muscarinic receptors.CHF5407 has an effect on bronchospasm and may be used in the study of respiratory disorders.CHF5407 is a potent and selective muscarinic M3 receptor antagonist with prolonged action at muscarinic receptors.
