Chemotaxonomy and geographical distribution of tropane alkaloids
Phytochemistry, 2000 This review illustrates the distribution of tropane alkaloids within the families Solanaceae, Erythroxylaceae, Proteaceae, Euphorbiaceae, Rhizophoraceae, Convolvulaceae and Cruciferae. Whereas tropane alkaloids are characteristic of the genera Datura, Brugmansia (tree datura) and Duboisia of the Solanaceae, the distribution is more widespread with ...

Complexation of tropane alkaloids by cyclodextrins
Carbohydrate Polymers, 2019Complexes of atropine, homatropine, scopolamine, and ipratropium with cyclodextrins were investigated by NMR and capillary electrophoresis. It has been demonstrated that tropane alkaloids form complexes with β- and γ-cyclodextrins of 1:1 stoichiometry.

The Chemical Synthesis and Applications of Tropane Alkaloids
, 2019 Tropanes are an important class of alkaloid natural products that are found in plants all over the world. These compounds can exhibit significant biological activity and are among the oldest known medicines. In the early 19th century, tropanes were isolated, characterized, and synthesized by notable chemical researchers.

Tropane alkaloids from Schizanthus litoralis [PDF]
Phytochemistry, 1996 Six new tropane alkaloids have been isolated from the leaves of the endemic Chilian plant Schizanthus litoralis (Solanaceae). The new structures include a new tropanol dimer of itaconic acid together with 6β- senecioyloxytropan-3α-methylmesaconate, 6β ...

Tropane alkaloids in food: poisoning incidents
Quality Assurance and Safety of Crops and Foods, 2014 A large number of wild and cultured plants produce secondary metabolites that can be toxic to humans and animals. The present study aims to provide insight into the routes of (un)intentional poisonings of humans by tropane alkaloids. Poisonings of humans

Conformation of Tropane Alkaloids
Nature, 1953IT has become generally accepted that cyclohexane compounds1 and pyranosides2 possess the chair conformation. By analogy we may assume that piperidine and its derivatives also exist in the chair conformation. Starting from this assumption, it is possible to determine the conformation of tropane alkaloids.

Tropane alkaloid biosynthesis: a centennial review
Natural Product Reports, 2021From the first ambitious imagination of tropinone biosynthesis mechanism in plants published in 1917 to the de novo production of scopolamine in yeast realized in 2020, what did we learn from this long story of more than 100 years old?

Analysis of tropane and related alkaloids
Journal of Chromatography A, 2002The current methods for tropane alkaloid chromatographic separation and determination are summarised. The alkaloids included are: the medicinally applied tropic acid esters hyoscyamine and scopolamine and their derivatives, cocaine and derivatives, the metabolites and degradation products of these compounds occurring in plant material, calystegines as ...

Tropane alkaloids and toxicity of Convolvulus arvensis
Phytochemistry, 1995Horses in a few, localized northern Colorado pastures exhibited weight loss and colic. At post mortem, intestinal fibrosis and vascular sclerosis of the small intestine was identified. The pastures where the affected horses grazed were overrun by field bindweed (Convolvulus arvensis). Bindweed from the pasture was found to contain the tropane alkaloids

Biosynthesis of Tropane Alkaloids
1989As with other secondary products, the biosynthesis of tropane alkaloids in plants has been extensively investigated by the use of labelled precursors (for a review, see [11]). Recent advances in the techniques of alkaloid analysis and enzyme purification, however, have now made it possible to isolate and characterize biosynthetic enzymes in the pathway,
