Plant phenols, powerful antioxidants, protect cells from oxidative stress. This review explores how these compounds, including flavonoids, activate cellular defense pathways and regulate autophagy for disease treatment.
Area of Science:
- Biochemistry
- Molecular Biology
- Pharmacology
Background:
- Plant phenols are potent antioxidants with therapeutic potential for various diseases.
- Oxidative stress contributes to cardiovascular, neurodegenerative, oncological, and inflammatory conditions.
- Phenolic compounds may exert protective effects beyond direct antioxidant activity.
Purpose of the Study:
- To review the mechanisms by which common plant phenols influence autophagy.
- To highlight the role of plant phenols in cellular defense pathways.
Main Methods:
- Literature review of studies on plant phenols and autophagy.
- Analysis of the Keap1/Nrf2/ARE signaling pathway activation by phenols.
- Examination of autophagy regulation by various classes of plant phenols.
Main Results:
- Plant phenols, including stilbenes, curcumins, catechins, and flavonoids, demonstrate significant antioxidant properties.
- Activation of the Keap1/Nrf2/ARE pathway is a key mechanism for phenolic compound protection.
- Phenols modulate autophagy, a cellular degradation process, contributing to their therapeutic effects.
Conclusions:
- Plant phenols offer protective effects against oxidative stress through antioxidant activity and modulation of cellular pathways.
- Understanding phenol-autophagy interactions is crucial for developing new treatments for oxidative stress-related diseases.
- Further research into specific plant phenols and their impact on autophagy is warranted.
