SMILES: C[N+]1([C@@H]2[C@H](O3)[C@H]3[C@H]1C[C@@H](OC([C@@H](C4=CC=CC=C4)CO)=O)C2)C.[Br-]
Biological Activity: Methscopolamine bromide ((-)-Scopolamine methyl bromide; Hyoscine methyl bromide) is a peripherally acting muscarinic receptor (mAChR) antagonist that cannot cross the blood-brain barrier. Methscopolamine bromide blocks the muscarinic negative feedback regulation of acetylcholine release from striatal cholinergic terminals, thereby increasing acetylcholine release in the striatum of freely moving rats. Methscopolamine bromide does not induce motor excitation in freely moving rats, nor does it alter the duration of ethanol-induced loss of righting reflex in mice. Methscopolamine bromide fails to antagonize the arecoline-mediated reduction in the duration of ethanol-induced loss of righting reflex in mice[1][2].

Atropine methyl bromide (Standard) | ≥98% | Atropine methyl bromide (Standard) is the analytical standard of Atropine methyl bromide. This product is intended for research and analytical applications. Atropine methyl bromide (Methylatropine bromide), an antagonist of muscarinic acetylcholine receptors (mAChR), is a quaternary ammonium salt of atropine and a mydriatic for dilation of the pupil during ophthalmic examination. It is introduced for relieving pyloric spasm in infants for its highly polar nature. It penetrates less readily into the central nervous system than atropine. | ||||||||||||||||||||

(±)-Scopolamine | (±)-Scopolamine (Atroscine) is the racemic form of Scopolamine (HY-N0296) and belongs to the tropane alkaloids. (±)-Scopolamine can be synthesized as the free base via an H2O2-mediated epoxidation reaction using 6,7-dehydrotropine as a key intermediate. (±)-Scopolamine is useful for the synthesis of tropane alkaloids and stereochemical studies. | |||||||||||||||||||||

Scopolamine butylbromide | 99.04% | 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. | ||||||||||||||||||||
