Lycopene: a review of its potential as an anticancer agent

Area of Science:

• Nutritional Science
• Molecular Biology
• Oncology

Background:

• Dietary chemoprevention is a cost-effective strategy against chronic diseases like cancer.
• Tomatoes and their products are recognized for extensive health benefits, particularly their high antioxidant capacity.
• Lycopene, a potent antioxidant carotenoid in tomatoes, effectively neutralizes reactive oxygen species (ROS).

Purpose of the Study:

• To review the sources, structure, absorption, metabolism, and bioavailability of lycopene.
• To explore the pharmacological properties of lycopene, focusing on its antioxidant and anticancer effects.
• To elucidate the mechanisms by which lycopene inhibits carcinogenesis.

Main Methods:

• Literature review of epidemiological, in vitro, and in vivo studies.
• Analysis of lycopene's chemical properties and biological activities.
• Examination of lycopene's role in cellular pathways related to cancer prevention.

Main Results:

• Lycopene demonstrates potent antioxidant and singlet oxygen quenching capabilities.
• Lycopene exhibits cardioprotective, anti-inflammatory, antimutagenic, and anticancer activities.
• Mechanisms include ROS scavenging, modulation of cell proliferation, and signal transduction pathways.

Conclusions:

• Lycopene is a key bioactive compound in tomatoes with significant chemopreventive potential.
• Its antioxidant and anticancer properties are supported by diverse biological effects and cellular mechanisms.
• Further research into lycopene's pharmacological applications is warranted.
