- Tropane alkaloid
Tropane alkaloids, also known as "Belladonna" alkaloids are a class of
alkaloids and secondary metabolites that contain a tropanering in their chemical structure. Tropane alkaloids occur naturally in many members of the plant family Solanaceae.
Important tropane alkaloids are:
Anticholinergic drugs and deliriants:
Atropine, racemic hyoscyamine, from the deadly nightshade("Atropa belladonna")
Hyoscyamine, the "levo"- isomerof atropine, from henbane(" Hyoscamus niger") and mandrake("Mandragora officinalis")
Scopolamine, from henbane and " Datura" species (Jimson weed)
Stimulants and cocaine-related alkaloids:
Cocaine, from " Erythroxylum coca"
Ecgonidine, and methylecgonidine, pyrolysisproducts of cocaine
Ecgonine, a precursor and metabolite of cocaine
Benzoylecgonine, a metabolite of cocaine
Cocaethylene, a metabolite of cocaine
Hydroxytropacocaine, from "Erythroxylum coca"
Methylecgonine cinnamate, from "Erythroxylum coca"
Catuabines, found in the drug catuaba, from " Erythroxylum vacciniifolium"
