'''Tropane alkaloids''' are a class of chemicals that include compounds with [[subjective effects index|psychoactive effects]].
'''Substituted tropanes''' (or simply '''tropanes''') are a group of [[psychoactive compounds]] that include a tropane ring in their structure. Prominent examples include certain [[stimulants]] like [[cocaine]] and its derivatives as well as [[deliriants]] like [[atropine]] and [[scopolamine]].

Tropanes are molecules which contain a substituted tropane ring in their structure. Tropane is a nitrogen-containing bicyclic organic molecule which consists of a [[piperidine]] and [[pyrrolidine]] ring fused at carbons R<sub>1</sub> and R<sub>5</sub> along with an additional methyl substitution at R<sub>N</sub>. It is mainly known for a group of [[alkaloids]] derived from it. Tropane alkaloids are commonly substituted at R<sub>3</sub> with an ether bridge (as seen in [[scopolamine]], [[atropine]], [[hyoscyamine]], and [[cocaine]]). Synthetic analogs of tropane alkaloids also exist, such as the phenyltropanes. They are not considered to be alkaloids per definition.

Tropane alkaloids are mostly [[Acetylcholine#The cholinergic system|anti-cholinergics]] (antagonistic action on acetylcholine [[receptors]]) or [[stimulant]]s (prevention of [[dopamine]] reuptake).
