Common Name

Tropine

Description

Tropine is a tropane alkaloid, a chemical class characterized by a bicyclic structure containing a nitrogen atom. Its chemical structure features a seven-membered ring fused with a six-membered ring, which is typical of tropane derivatives. Tropine serves as a critical biosynthetic intermediate in the production of various alkaloids, including atropine and scopolamine, which are derived from it through enzymatic modifications (PMID:41003533 ). In the context of pharmacology, tropine and its analogues have been studied for their effects on opioid-induced respiratory depression, with isobutyric tropine ester (Ibutropin) demonstrating the ability to mitigate respiratory depression without compromising analgesia in animal models (PMID:40258571 ). Additionally, tropine has been utilized in analytical methods for the determination of tropane alkaloids, such as atropine and scopolamine, through enzymatic oxidation processes (PMID:40208267 ). The kinetic characterization of tropinone oxidase has further facilitated the simultaneous analysis of these compounds (PMID:40208267 ). Overall, tropine plays a significant role in both the biosynthetic pathways of various alkaloids and in pharmacological studies related to respiratory control mechanisms (PMID:40258571 ).
