tropaanalkaloïden

Tropaanalkaloïden is a class of naturally occurring organic compounds that share a common tropane skeleton. This bicyclic structure consists of a piperidine ring bridged by a methylene group. These alkaloids are primarily found in plants belonging to the Solanaceae family, which includes well-known species such as belladonna, datura, and henbane. They are also present in some plants from other families, like Erythroxylaceae, the source of coca.

The pharmacological effects of tropaanalkaloïden are diverse and often potent, largely due to their ability to interact with neurotransmitter receptors in the nervous system. Many tropaanalkaloïden act as antagonists of muscarinic acetylcholine receptors, leading to anticholinergic effects. This can manifest as a range of symptoms including dilated pupils, dry mouth, increased heart rate, and in higher doses, hallucinations and delirium. Some examples of prominent tropaanalkaloïden include atropine, scopolamine, and cocaine. Atropine and scopolamine have historically been used in medicine for their anticholinergic properties, such as in ophthalmology and to treat motion sickness. Cocaine, on the other hand, is a stimulant that also exhibits local anesthetic properties and is known for its significant potential for abuse. The biosynthesis of tropaanalkaloïden is complex, involving amino acid precursors and a series of enzymatic reactions. Due to their toxicity and psychoactive properties, tropaanalkaloïden-containing plants have been used in traditional medicine and shamanistic rituals for centuries, but their medicinal use requires careful dosage and professional supervision.
