Overview of the Anticancer Profile of Avenanthramides from Oat

Area of Science:

• Phytochemistry
• Pharmacology
• Oncology

Background:

• Cancer remains a leading global cause of death, with treatment challenges including side effects and drug resistance.
• Natural products, particularly polyphenols, offer a promising avenue for developing novel anticancer strategies.
• Oat (Avena sativa) contains unique signature compounds called avenanthramides (AVAs), a group of polyphenolic alkaloids.

Purpose of the Study:

• To provide a comprehensive review of the chemopreventive and chemotherapeutic potential of avenanthramides (AVAs).
• To critically assess the mechanisms by which AVAs may prevent and treat cancer.

Main Methods:

• Literature review of studies investigating avenanthramides (AVAs) and their biological activities.
• Analysis of pathways modulated by AVAs, including antioxidant effects, apoptosis, senescence, cell proliferation, and epithelial-mesenchymal transition.

Main Results:

• Avenanthramides (AVAs) demonstrate chemopreventive effects primarily by neutralizing reactive oxygen species.
• AVAs exhibit therapeutic potential by modulating key cancer pathways, including inducing apoptosis and senescence.
• AVAs can inhibit cancer progression by blocking cell proliferation and suppressing epithelial-mesenchymal transition and metastatization.

Conclusions:

• Avenanthramides (AVAs) are promising phytochemicals with both chemopreventive and anticancer properties.
• Further clinical trials and toxicological studies are essential to establish the efficacy of AVAs in cancer prevention and treatment.
• AVAs represent a potential natural product-based strategy to reduce the global burden of cancer diseases.
