Recent discoveries of anticancer flavonoids

Area of Science:

• Natural Product Chemistry
• Pharmacology
• Medicinal Chemistry

Background:

• Flavonoids are a diverse class of natural compounds with a wide range of biological activities.
• Their anticancer potential has been recognized, but recent advancements require systematic review.
• Understanding structure-activity relationships is key to developing effective anticancer agents.

Purpose of the Study:

• To review recent advances in the anticancer activity of natural flavonoids.
• To categorize and analyze studies based on the source of bioactivity (plant extracts vs. purified compounds).
• To detail mechanisms of action, targets, and structure-activity relationships of flavonoids with anticancer properties.

Main Methods:

• Comprehensive literature search of scientific databases for studies published in the last five years.
• Categorization of retrieved studies based on the reporting of plant extract bioactivity versus purified flavonoid activity.
• Extraction and synthesis of data on identified flavonoids, their biological targets, mechanisms of action, and structure-activity relationships.

Main Results:

• Recent studies show significant anticancer activity for various natural flavonoids.
• Findings are presented distinguishing between crude plant extracts and isolated, identified flavonoids.
• Detailed information on mechanisms, targets, and structure-activity relationships is provided for key compounds.
• Exploration of flavonoids with the 2-phenyl-4H-chromen-4-one core and unusual flavonoid structures.

Conclusions:

• Natural flavonoids represent a promising source for anticancer drug development.
• Further research into purified flavonoids and their specific mechanisms is warranted.
• Structure-activity relationship studies are crucial for optimizing flavonoid-based anticancer therapies.
