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.

Atropine sulfate (Sulfatropinol) is a competitive antagonist for muscarinic acetylcholine receptor.

Atropine sulfate monohydrate (Atropine sulfate hydrate), the sulfate salt of atropine, is a competitive muscarinic acetylcholine receptor antagonist.

Noratropine is a metabolite of Atropine (A794625).

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.

Tropinone used as an intermediate in the synthesis of atropine sulfate, and is a decane alkaloid.

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.

Anisodamine hydrochloride, an anticholinergic and α1 adrenergic receptor antagonist, is used for enhancing blood flow in circulatory disorders like septic shock. It exhibits a range of pharmacological effects similar to Atropine and Scopolamine, including the inhibition of salivation, gastrointestinal and sweat secretion, gastrointestinal motility, respiratory secretion, and urinary bladder contraction in vivo [1].

Littorine is a tropane alkaloid found in a variety of plants including Datura and Atropa belladonna. It is closely related in chemical structure to atropine, hyoscyamine, and scopolamine, which all share a common biosynthetic pathway.

L-Hyoscyamine sulfate hydrate, a naturally occurring tropane alkaloid, acts as an effective competitive antagonist of muscarinic receptors (MR). It is the levorotary isomer of Atropine.

Tigloidin is an atropine analog with anticholinergic activity.

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.
