Complexation of tropane alkaloids by cyclodextrins

Carbohydrate Polymers, 2019
Complexes 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.

Analysis of tropane and related alkaloids

Journal of Chromatography A, 2002
The 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 ...

Conformation of Tropane Alkaloids

Nature, 1953
IT 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 and Related Alkaloids

2000
Tropane alkaloids comprise a large group of bases occurring predominantly in the family of the Solanaceae. Structurally they are esters of carboxylic acids with tropine (3-hydroxy-8-aza-8-methyl-[3.2.1]-bicyclooctane) and are biosynthetically derived from amino acid and acetate precursors.
