Epigomisin O is a dibenzocyclooctadiene lignan isolated from Schisandra chinensis, used in research for its potential neuroprotective properties, particularly in studies related to Alzheimer's disease. It shows ability to modulate enzyme activity involved in neuroinflammation and oxidative stress. Investigated for cognitive enhancement due to its influence on synaptic function and neuronal health. Also explored for anti-aging applications in cellular models, as well as anti-inflammatory and hepatoprotective effects.
