The brain is a highly metabolic organ, producing a large number of free radicals during normal physiological activities, such as superoxide anion radicals and hydroxyl radicals. These free radicals have strong oxidizing properties, attacking the cell membranes and mitochondria of nerve cells, leading to cell damage and death, and consequently triggering neurodegenerative diseases. Fisetin are a potent free radical scavenger. The phenolic hydroxyl group in its molecular structure can provide hydrogen atoms to combine with free radicals, reducing them to relatively stable molecules, thereby reducing the damage of free radicals to nerve cells. Studies have shown that Fisetin can significantly reduce the levels of oxidative stress markers in the brain, such as malondialdehyde (MDA), while increasing the activity of antioxidant enzymes, such as superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and catalase (CAT), thereby enhancing the antioxidant defense capacity of nerve cells and protecting them from oxidative damage.

Anti-inflammatory effects: Inhibiting inflammatory responses and reducing neuroinflammation

Neuritis is an important pathological basis for the development of many neurodegenerative diseases, such as Alzheimer’s disease and Parkinson’s disease. During neuroinflammation, microglia are activated, releasing large amounts of inflammatory mediators, such as tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6). These inflammatory mediators further damage nerve cells, leading to neurological dysfunction. Fisetin can inhibit microglia activation and reduce the release of inflammatory mediators, thereby alleviating neuroinflammation. Its mechanisms of action mainly include inhibiting the activation of the NF-κB signaling pathway, reducing the expression of inflammation-related genes, regulating the mitogen-activated protein kinase (MAPK) signaling pathway, and inhibiting the production of inflammatory cytokines. By reducing neuroinflammation, Fisetin create a relatively healthy microenvironment for nerve cells, helping to maintain normal nerve cell function.

Neuroprotective effects: Promoting neuronal connections and regulating neurotransmitters

Connections between neurons (synapses) are crucial for the transmission of nerve signals and normal brain function. In neurodegenerative diseases, these connections are disrupted, leading to impaired nerve signal transmission and consequently affecting cognitive function. Fisetin have been found to promote the formation of connections between neurons, enhance the efficiency of neurotransmitter transmission, and help improve brain plasticity, thereby improving cognitive function. For example, Fisetin can promote the expression of brain-derived neurotrophic factor (BDNF), a protein that plays an important role in the growth, survival, and differentiation of neurons. BDNF can promote neuronal growth and differentiation, enhance synaptic plasticity, and thus improve cognitive function. Furthermore, Fisetin can regulate neurotransmitter levels in the brain, such as increasing the level of acetylcholine (ACh). ACh is a neurotransmitter that plays a crucial role in learning and memory, participating in the transmission of nerve signals in the hippocampus (a brain region closely related to learning and memory). Fisetin enhance nerve signal transmission by promoting ACh synthesis or reducing its breakdown, thereby improving learning ability.
