Chemical structure of tropane which forms the core of tropane alkaloids Chemical structure and phylogeny of tropane alkaloids. Displayed are 3 chemical compounds that occur as natural products in 5 plant species. Tropane alkaloids are a class of bicyclic [3.2.1] alkaloids and secondary metabolites that contain a tropane ring in their chemical ...
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 ).
Tropane alkaloid biosynthesis is another avenue of defense with codons positively selected and expanded in the Datura branch. It is aided by the tropane alkaloid Littorine rearrangement which is very important to scopolamine and atropine/hyoscyamine production, all of which serve to debilitate any organism that would come into contact with them.
Of the approximately 200 members in the genus Erythroxylum, most species contain the central nervous system stimulant tropane alkaloid, known more commonly as cocaine.Because the plant is endemic ...
Such alkaloid-related substances as serotonin, dopamine and histamine are important neurotransmitters in animals. Alkaloids are also known to regulate plant growth. [202] One example of an organism that uses alkaloids for protection is the Utetheisa ornatrix, more commonly known as the ornate moth.
One interesting example of plant/animal interaction involves the butterfly Placidula euryanassa, which uses Brugmansia suaveolens as one of its main larval foods. It has been shown that these can sequester the plant's tropane alkaloids and store them through the pupal stage on to the adult butterfly, where they are then used as a defense ...
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, the sorcerers' tree, and Atropa belladonna (deadly nightshade).
