Aplicação

Acetyl-β-methylcholine bromide (methylcholine bromide, methacholine bromide, Mch), a muscarinic acetylcholine receptor agonist, may be used in studies that involve the indentification, characterization and mechanism of action of muscarinic acetylcholine receptors. Mch may be used as a reference material in procedures used to detect or quantify its presence.

1. We have examined possible mechanisms of cross-talk between the G(q/11)-linked M(3) muscarinic acetylcholine (mACh) receptor and the G(i/o)-linked M(2) mACh receptor by stable receptor coexpression in Chinese hamster ovary (CHO) cells. A number of second messenger (cyclic AMP, Ins(1,4,5)P(3))

The presence of multiple muscarinic acetylcholine receptor (mAChR) subtypes in the heart and lung, combined with the lack of mAChR subtype-selective ligands, have complicated the task of identifying the mAChR subtypes mediating cardiac slowing (bradycardia) and airway narrowing (bronchoconstriction) due

Development of combination therapies has received significant interest in recent years. Previously, a two-receptor one-transducer (2R-1T) model was proposed to characterize drug interactions with two receptors that lead to the same phenotypic response through a common transducer pathway. We applied

Solutions of histamine and methacholine bromide in different matrices for diagnostic purposes were analyzed for stability and quality control using capillary electrophoresis. Histamine (2,[4-imidazolyl]ethylamine) [CAS No. 51-45-6] was determined using a 0.1 M Tris-borate buffer of pH 8.3 with 5.10(-5)

Members of the muscarinic acetylcholine receptor family (M1-M5) have central roles in the regulation of many fundamental physiological functions. Identifying the specific receptor subtype(s) that mediate the diverse muscarinic actions of acetylcholine is of considerable therapeutic interest, but has proved
