Atropine

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.

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.

Atropine methyl bromide (Methylatropine bromide) is a quaternary ammonium salt of atropine, characterized as a muscarinic receptor (mAChR) antagonist. It functions as a mydriatic to dilate the pupil during ophthalmic examination. Compared to atropine, it demonstrates reduced penetration into the central nervous system[1][2]. Its high polarity makes it particularly effective in relieving pyloric spasm in infants.

Atropine Oxide Hydrochloride is a derivative of Atropine. Atropine is utilized in research involving nerve agent and pesticide poisoning models, selected forms of bradycardia, and salivary secretion regulation during surgical procedures. Atropine functions as a competitive antagonist of muscarinic acetylcholine receptor subtypes M1, M2, M3, M4, and M5 and is classified as an anticholinergic (parasympatholytic) compound. Atropine Oxide Hydrochloride is therefore relevant for pharmacological investigations involving cholinergic neurotransmission, receptor antagonism, autonomic nervous system regulation, and toxicological response mechanisms.

(±)-Atropine-D3(N-methyl-D3) is a deuterated compound of  (±)-Atropine (TMSM-0473). (±)-Atropine has a CAS number of 51-55-8. Atropine 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-D5 is the deuterated form of Atropine sulfate monohydrate (T0375L) . Atropine (Tropine tropate) sulfate monohydrate serves as a broad-spectrum, competitive antagonist of muscarinic acetylcholine receptors (mAChR) and exhibits anti-myopia properties.
