The chemical structure of tropane

Tropane alkaloids are a class of bicyclic [3.2.1] alkaloids and secondary metabolites that contain a tropane ring in their chemical structure. Tropane alkaloids occur naturally in many members of the plant family Solanaceae. Some tropane alkaloids have pharmacological properties and can act as anticholinergics or stimulants.
