    Hyoscine butylbromide; (-)-Scopolamine butylbromide; Butylscopolamine bromide

    		 mAChR Neurological Disease Inflammation/Immunology
    Scopolamine butylbromide (Hyoscine butylbromide) is an orally active anticholinergic agent and spasmolytic. Scopolamine butylbromide binds with high affinity to rat cardiac M2 (Ki 83 nmol/L), hM2 (Ki 233 nmol/L), rat intestinal M3 (Ki 290 nmol/L) and hM3 (Ki 643 nmol/L) muscarinic receptors. Scopolamine butylbromide exerts a dose-dependent antagonistic effect on Carbachol-induced gastrointestinal smooth muscle spasm. Scopolamine butylbromide can be used for the research of abdominal colic and pain associated with gastrointestinal spasm, functional abdominal pain, chronic gastropathy and gastric ulcer .

    Oxomemazine

    		Histamine Receptor mGluR Inflammation/Immunology
    Oxomemazine is a phenothiazine-based histamine H1-receptor blocker. Oxomemazine is a selective antagonist for muscarinic M1 receptor, displays about 20-fold difference in the affinity for high (Ki = 84 nM, M1 receptor) and low (Ki = 1.65 μM, M2 receptor) affinity sites. Oxomemazine is an antihistamine and anticholinergic agent used for the study of cough treatment. Oxomemazine is protective against anaphylactic microshock in guinea pigs .

    Oxomemazine (Standard)

    		Reference Standards Histamine Receptor mGluR Inflammation/Immunology
    Oxomemazine (Standard) is the analytical standard of Oxomemazine (HY-136587). This product is intended for research and analytical applications. Oxomemazine is a phenothiazine-based histamine H1-receptor blocker. Oxomemazine is a selective antagonist for muscarinic M1 receptor, displays about 20-fold difference in the affinity for high (Ki = 84 nM, M1 receptor) and low (Ki = 1.65 μM, M2 receptor) affinity sites. Oxomemazine is an antihistamine and anticholinergic agent used for the study of cough treatment. Oxomemazine is protective against anaphylactic microshock in guinea pigs .

    NPC-14695

    		mAChR Neurological Disease Inflammation/Immunology
    NPC-14695 is a competitive and selective M3 muscarinic receptor antagonist, with a Kd value of 15 nM for guinea pig M3, 60 nM for guinea pig M2, and 25 nM for rabbit M1. NPC-14695 exhibits higher activity towards M3 receptors in bronchial smooth muscle than towards those regulating salivary secretion. NPC-14695 inhibits Carbachol (HY-B1208)-induced contraction of isolated rabbit iris smooth muscle .

  • HY-126862
    AQ-RA 721

    		mAChR Others
    AQ-RA 721 is a muscarinic receptor antagonist with differential affinity for the m4 and M2 sites, which can be used to characterize muscarinic receptor subtypes. Other muscarinic receptor antagonists have differential affinity for the M1 (rat cerebral cortex), M2 (rat heart), M3 (rat submandibular gland), m4 (receptor expressed in Chinese hamster ovary cells transfected with CHO), and guinea pig uterine smooth muscle at the muscarinic binding site .
