Tropane alkaloids are a class of bicyclic [3.2.1] alkaloids and secondary metabolites that contain a tropane ring in their chemical structure. [1] Tropane alkaloids occur naturally in many members of the plant family Solanaceae.

Tropane alkaloids (TAs) are a specific class of alkaloid and can be more specifically defined as all molecules that possess a tropane ring system (Figure 1 Structure of the tropane skeleton (green box) and the three major groups of TAs derived from, green box) .

2019年2月22日 · Tropane alkaloids (TA) are valuable secondary plant metabolites which are mostly found in high concentrations in the Solanaceae and Erythroxylaceae families. The TAs, which are characterized by their unique bicyclic tropane ring system, can be divided into three major groups: hyoscyamine and scopola …

Tropane is the condensation product of pyrrolidine precursor (ornithine) and piperidine ring with a common nitrogen and two carbon atoms . In nature, TAs occur as ester formed by the combination of organic acids (tropic acid) and alcoholic base (tropanol).

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). [2] [3]

Tropane is a bicyclic amine that has a pyrrolidine and a piperidine ring sharing a common nitrogen atom and 2 carbon atoms. It is the common structural element of all tropane alkaloids

TAs are a type of alkaloids with a tropane ring in their chemical structure, characterized by a two-ringed structure with pyrrolidine and piperidine rings sharing a single nitrogen atom and two carbon atoms (Figure 2). Most of them are esters derived …

Specifically it focuses on tropane, a fascinating, naturally occurring bicyclic chemical ring system that lends itself to many pharmaceutical and therapeutic applications.

2012年7月15日 · Tropane is regarded as the principle base of a plethora of alkaloids obtained from various members of the natural order, viz., Solanaceae, Erythroxylaceae, Convolvulaceae, and Dioscoreaceae. It essentially consists of a 7-carbon bicyclic ring with a N-atom strategically bridged between C-1 and C-5 and providing a C 7 N unit.
