Narcissus pseudonarcissus
Classic European spring bulb with yellow flowers, source of galantamine for Alzheimers disease treatment.
Narcissus pseudonarcissus, the wild daffodil, is a European bulb historically used in folk medicine and now cultivated as a commercial source of galantamine, an acetylcholinesterase inhibitor approved for Alzheimer's disease. The plant contains several alkaloids including galantamine, lycorine, and narciclasine, which contribute to its neurological and toxicological profile. Despite its therapeutic potential, raw plant material is highly toxic and only processed galantamine is used clinically.
Galantamine, the primary active compound, is a reversible, competitive acetylcholinesterase inhibitor that increases synaptic acetylcholine levels, enhancing cholinergic neurotransmission. It also acts as an allosteric potentiating ligand at nicotinic acetylcholine receptors, further augmenting cholinergic function. Other alkaloids such as lycorine and narciclasine exhibit antiviral, anti-inflammatory, and anticancer activities in preclinical studies, but their mechanisms are less defined and they are not used therapeutically due to toxicity.
