Studies on the biosynthesis of tropane alkaloids in Datura
Tropane Alkaloids Food and feed in the spotlight Tropane alkaloids (TA) are secondary metabolites with more than 200 different substances identified in various plants. When growing in direct vicinity of crops, tropane alkaloid containing plants are potential contaminants of various food and feeding stuffs. The risk of contamina-tion usually increases if seeds of the alkaloid containing plant... Tropane alkaloids, atropine, hyoscyamine and scopolamine, are among the oldest drugs in medicine. On the other hand nicotine, the addictive agent in tobacco, has only recently gained attention as a backbone for novel potential alkaloids to be used for certain neurological diseases. The biotechnological production of alkaloids utilizing plant cells as hosts would be an attractive option

ALKALOID BIOSYNTHESIS IN PLANTS Biochemistry Cell
Abstract. 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. the logician and the engineer pdf Plant tropane alkaloid biosynthesis evolved independently in the Solanaceae and Erythroxylaceae Jan Jirschitzkaa, Gregor W.

- Abstract Recent advances in the cell, developmental, and molecular biology of alkaloid biosynthesis have heightened our appreciation for the complexity and importance of plant secondary pathways. Several biosynthetic genes involved in the formation of tropane, benzylisoquinoline, and terpenoid indole alkaloids have now been isolated. The early
- Tropane derivatives Ways of alkaloid biosynthesis are too numerous and cannot be easily classified. However, there are a few typical reactions involved in the biosynthesis of various classes of alkaloids, including synthesis of Schiff bases and Mannich reaction.
- Tropane alkaloids Alkaloids possessing the tropane skeleton are common in various plants. As most of the tropane alkaloids possess pronounced biological properties, plants with high content of tropane alkaloids have been used in herbal folk medicine, for recreational drug use, and as poison. The most prominent members of plants producing tropane alkaloids are Solanaceae (nightshade or potato
