Galanthus nivalis
European native bulb containing galantamine, used in Eastern European folk medicine for neurological conditions.
Snowdrop (Galanthus nivalis) is a bulbous plant native to Europe, historically used in Bulgarian folk medicine for neurological conditions and as a source of the alkaloid galantamine, a standard pharmaceutical treatment for Alzheimer disease. Its primary active compound, galantamine, acts as a reversible acetylcholinesterase inhibitor, while other alkaloids such as lycorine and tazettine contribute to its neuroprotective and toxicological profile. Despite its traditional use, the raw plant is considered toxic and is not used directly; only purified galantamine is employed clinically.
Galantamine, the principal active alkaloid, is a competitive, reversible inhibitor of acetylcholinesterase (AChE), increasing acetylcholine levels in synaptic clefts and enhancing cholinergic neurotransmission. It also acts as an allosteric modulator of nicotinic acetylcholine receptors (nAChRs), potentiating receptor response to acetylcholine. Additionally, galantamine exhibits antioxidant and anti-inflammatory properties, reducing oxidative stress and microglial activation in neuronal tissues. Other alkaloids like lycorine inhibit protein synthesis and may contribute to both neuroprotective and toxic effects depending on dose.
