Flavonoids with Anti-Angiogenesis Function in Cancer

Area of Science:

• Molecular Biology
• Pharmacology
• Plant Biochemistry

Background:

• Angiogenesis, the formation of new blood vessels, is crucial for cancer development and progression.
• Current anti-angiogenic therapies often involve expensive or toxic synthetic compounds and antibodies.
• There is a critical need for affordable, less toxic, and effective anti-angiogenic agents.

Purpose of the Study:

• To review the anti-angiogenic properties of naturally derived flavonoids from plants.
• To elucidate the molecular mechanisms through which these flavonoids exert their anti-angiogenic effects.
• To summarize flavonoid structures, classifications, and their interactions with plant signaling pathways.

Main Methods:

• Literature review of studies on plant-derived flavonoids and their anti-angiogenic activities.
• Analysis of molecular mechanisms, focusing on key signaling pathways involved in angiogenesis.
• Summary of flavonoid structure-activity relationships and their classification.

Main Results:

• Naturally derived flavonoids exhibit significant anti-angiogenic potential.
• Flavonoids modulate critical signaling pathways including HIF-1α/VEGF/VEGFR2/PI3K/AKT, Wnt/β-catenin, JNK1/STAT3, and MAPK/AP-1.
• Plant-derived flavonoids offer a promising alternative to synthetic anti-angiogenic drugs.

Conclusions:

• Plant-derived flavonoids represent a valuable source of novel anti-angiogenic compounds.
• Understanding their molecular mechanisms provides a basis for developing new cancer therapies.
• Further research is needed to improve flavonoid bioavailability for clinical applications.
