Tellimagrandin II (Eugeniin), with oral activity, is the first intermediate of the ellagitannin series derived from 4C1-glucose. It inhibits the resistance of Staphylococcus aureus by disrupting the integrity of the cell wall, leading to the loss of cytoplasmic contents. Additionally, Tellimagrandin II exhibits anti-inflammatory effects and inhibits acetylcholinesterase (AChE) activity, improving memory impairment. Tellimagrandin II holds potential for research in the fields of antibacterial, anti-inflammatory, and neurodegenerative diseases.
