Hyoscyamine
Hyoscyamine (also known as daturine or duboisine) is a naturally occurring tropane alkaloid and plant toxin. It is a secondary metabolite found in certain plants of the family Solanaceae, including henbane, mandrake, angel's trumpets, jimsonweed, tomato, the sorcerers' tree, and deadly nightshade. It is the levorotary isomer of atropine (third of the three major nightshade alkaloids) and thus sometimes known as levo-atropine. Brand names for hyoscyamine include Symax, HyoMax, Anaspaz, Egazil, Buwecon, Cystospaz, Levsin, Levbid, Levsinex, Donnamar, NuLev, Spacol T/S, and Neoquess. Uses Hyoscyamine is used to provide symptomatic relief of spasms caused by various lower abdominal and bladder disorders including peptic ulcers, irritable bowel syndrome, diverticulitis, pancreatitis, colic, and interstitial cystitis. It has also been used to relieve some heart problems, control some of the symptoms of Parkinson's disease, as well as for control of abnormal respiratory symptoms and " ...

Hyoscine Hydrobromide
Scopolamine, also known as hyoscine, or Devil's Breath, is a natural or synthetically produced tropane alkaloid and anticholinergic drug that is formally used as a medication for treating motion sickness and postoperative nausea and vomiting. It is also sometimes used before surgery to decrease saliva. When used by injection, effects begin after about 20 minutes and last for up to 8 hours. It may also be used orally and as a transdermal patch since it has been long known to have transdermal bioavailability Scopolamine is in the antimuscarinic family of drugs and works by blocking some of the effects of acetylcholine within the nervous system. Scopolamine was first written about in 1881 and started to be used for anesthesia around 1900. Scopolamine is also the main active component produced by certain plants of the nightshade family, which historically have been used as psychoactive drugs (known as ''deliriants'') due to their antimuscarinic-induced hallucinogenic ef ...

Atropine
Atropine is a tropane alkaloid and anticholinergic medication used to treat certain types of nerve agent and pesticide poisonings as well as some types of slow heart rate, and to decrease saliva production during surgery. It is typically given intravenously or by injection into a muscle. Eye drops are also available which are used to treat uveitis and early amblyopia. The intravenous solution usually begins working within a minute and lasts half an hour to an hour. Large doses may be required to treat some poisonings. Common side effects include a dry mouth, large pupils, urinary retention, constipation, and a fast heart rate. It should generally not be used in people with angle closure glaucoma. While there is no evidence that its use during pregnancy causes birth defects, that has not been well studied. It is likely safe during breastfeeding. It is an antimuscarinic (a type of anticholinergic) that works by inhibiting the parasympathetic nervous system. Atropine occurs n ...

Tropane Alkaloid
Tropane alkaloids are a class of bicyclic [3.2.1] alkaloids and secondary metabolites that contain a tropane ring in their chemical structure. Tropane alkaloids occur naturally in many members of the plant family Solanaceae. Certain tropane alkaloids such as cocaine and scopolamine are notorious for their psychoactive effects, related usage and cultural associations. Particular tropane alkaloids such as these have pharmacological properties and can act as anticholinergics or stimulants. Classification Anticholinergics Anticholinergic drugs and deliriants: * Atropine, racemate, racemic hyoscyamine, from the deadly nightshade (''Atropa belladonna'') * Hyoscyamine, the ''levo''-isomer of atropine, from henbane (''Hyoscyamus niger''), mandrake (''Mandragora officinarum'') and the sorcerers' tree (''Latua pubiflora''). * Hyoscine hydrobromide, Scopolamine, from henbane and ''Datura'' species (Jimson weed) All three acetylcholine-inhibiting chemicals can also be found in the leave ...

Datura
''Datura'' is a genus of nine species of highly poisonous, vespertine-flowering plants belonging to the nightshade family Solanaceae. They are commonly known as thornapples or jimsonweeds, but are also known as devil's trumpets (not to be confused with angel's trumpets, which are placed in the closely related genus ''Brugmansia''). Other English common names include moonflower, devil's weed, and hell's bells. All species of ''Datura'' are extremely poisonous and potentially psychoactive, especially their seeds and flowers, which can cause respiratory depression, arrhythmias, fever, delirium, hallucinations, anticholinergic syndrome, psychosis, and even death if taken internally. Due to their effects and symptoms, they have occasionally been used not only as poisons, but also as hallucinogens by various groups throughout history. Traditionally, psychoactive administration of ''Datura'' species has often been associated with witchcraft and sorcery or similar practices in man ...

Atropa Belladonna
''Atropa belladonna'', commonly known as belladonna or deadly nightshade, is a toxic perennial herbaceous plant in the nightshade family Solanaceae, which also includes tomatoes, potatoes, and eggplant (aubergine). It is native to Europe, North Africa, and Western Asia. Its distribution extends from Great Britain in the west to western Ukraine and the Iranian province of Gilan in the east. It is also naturalised or introduced in some parts of Canada and the United States. The foliage and berries are extremely toxic when ingested, containing tropane alkaloids. These toxins include atropine, scopolamine, and hyoscyamine, which cause delirium and hallucinations, and are also used as pharmaceutical anticholinergics. Tropane alkaloids are of common occurrence not only in the Old World tribes Hyoscyameae (to which the genus Atropa belongs) and Mandragoreae, but also in the New World tribe Datureae - all of which belong to the subfamily Solanoideae of the plant family Solanaceae. ...

Biosynthesis
Biosynthesis is a multi-step, enzyme-catalyzed process where substrates are converted into more complex products in living organisms. In biosynthesis, simple compounds are modified, converted into other compounds, or joined to form macromolecules. This process often consists of metabolic pathways. Some of these biosynthetic pathways are located within a single cellular organelle, while others involve enzymes that are located within multiple cellular organelles. Examples of these biosynthetic pathways include the production of lipid membrane components and nucleotides. Biosynthesis is usually synonymous with anabolism. The prerequisite elements for biosynthesis include: precursor compounds, chemical energy (e.g. ATP), and catalytic enzymes which may require coenzymes (e.g.NADH, NADPH). These elements create monomers, the building blocks for macromolecules. Some important biological macromolecules include: proteins, which are composed of amino acid monomers joined via peptide bon ...

Catuabine
Catuabines are a group of tropane alkaloids, isolated from '' Erythroxylum vaccinifolium'', which are used in the preparation of the drug Catuaba (which in traditional Brazilian medicine is purported to be an aphrodisiac and central nervous system stimulant, though such claims have not been substantiated). While catuabine A, B and C were isolated and characterized by Graf and Lude (1977, 1978), catuabine D was recently isolated by Zanolari et al. The catuabines are not known to have any physiological effects, this is in contrast to cocaine, which is an active constituent of another species, ''Erythroxylum coca''.

Scopine
Scopine is a tropane alkaloid found in a variety of plants including '' Mandragora'' root, '' Senecio mikanioides'' (''Delairea odorata''), ''Scopolia carniolica'', and '' Scopolia lurida''. Scopine can be prepared by the hydrolysis of scopolamine. It can also be prepared in three steps from ''N''-methoxycarbonylpyrrole and 1,1,3,3-tetrabromoacetone; the reagents are combined in a +3cycloaddition, followed by a diastereoselective reduction with diisobutylaluminum hydride, and finally a Prilezhaev epoxidation with trifluoroperacetic acid affords scopine.

Tropane Alkaloids Found In Solanaceae
Tropane is a nitrogenous bicyclic organic compound. It is mainly known for the other alkaloids derived from it, which include atropine and cocaine, among others. Tropane alkaloids occur in plants of the families Erythroxylaceae (including coca) and Solanaceae (including mandrake, henbane, deadly nightshade, datura, potato, tomato). Structurally, tropane is cycloheptane with a nitrogen bridge between carbons 1 and 5 and an additional methyl group attached to the nitrogen. While carbons 1 and 5 are asymmetric carbons, tropane itself is optically inactive due to mirror symmetry. 8-Azabicyclo .2.1ctane (tropane without the ''N''-methyl group) is known as nortropane or nor-tropane. See also * Phenyltropane * Tropane alkaloid * Tropine Tropine is a derivative of tropane containing a hydroxyl group at the third carbon. It is also called 3-tropanol. Tropine is a central building block of many chemicals active in the nervous system, including tropane alkaloids. Some of these comp . ...
