Flavonoids as Potential Anti-Inflammatory Molecules: A Review.

Area of Science:

• Biochemistry
• Pharmacology
• Nutrition Science

Background:

• Flavonoids, a class of hydroxylated polyphenols abundant in plants, possess diverse medicinal properties.
• These compounds are recognized for their antioxidant, anti-cancer, anti-microbial, neuroprotective, and anti-inflammatory activities.

Purpose of the Study:

• To review the sources, biochemical activities, and health-enhancing roles of flavonoids, particularly their anti-inflammatory mechanisms.
• To highlight the potential of flavonoids in managing various inflammatory conditions.

Main Methods:

• Literature review of studies on flavonoid sources and their biochemical activities.
• Analysis of research detailing the molecular mechanisms of flavonoid anti-inflammatory action.
• Synthesis of information on the therapeutic implications of flavonoids for inflammatory diseases.

Main Results:

• Flavonoids activate antioxidant pathways, leading to anti-inflammatory effects.
• They inhibit pro-inflammatory enzymes (e.g., inducible nitric oxide synthase, cyclooxygenase-2) and modulate cytokine expression (e.g., IL-1β, TNF-α).
• Flavonoids regulate gene expression of inflammatory molecules like NF-κB and adhesion molecules (e.g., ICAM, VCAM).

Conclusions:

• Flavonoids demonstrate significant anti-inflammatory properties through multiple biochemical pathways.
• Understanding these mechanisms can lead to improved therapeutic strategies for inflammatory diseases such as COVID-19, IBD, arthritis, and cardiovascular diseases.
• Flavonoids represent a promising area for natural product-based health enhancement.
