Cardioprotective effects of phytopigments via multiple signaling pathways

Area of Science:

• Plant-derived compounds
• Cardiovascular research
• Pharmacology

Background:

• Cardiovascular diseases (CVDs) are a leading cause of mortality, with complex origins hindering effective treatment development.
• Phytopigments, natural plant compounds, demonstrate versatile cardioprotective properties in laboratory and animal studies.
• Significant financial resources are allocated annually to manage and treat CVDs.

Purpose of the Study:

• To review the cardioprotective effects of various phytopigments.
• To synthesize findings from in vitro, in vivo, and clinical studies on phytopigments and cardiovascular health.

Main Methods:

• A comprehensive literature search was conducted using major scientific databases (PubMed, Google Scholar, Scopus).
• Data on the cardioprotective activities of phytopigments were systematically collected and analyzed.

Main Results:

• Carotenoids, xanthophylls, flavonoids, anthocyanins, and anthraquinones were identified as key phytopigment classes with cardioprotective potential.
• These compounds mitigate cardiovascular conditions like cardiac hypertrophy, atherosclerosis, and hypertension.
• Mechanisms involve modulation of critical signaling pathways including AMPK, NF-κB, NRF2, and MAPK.

Conclusions:

• Phytopigments show considerable promise as novel therapeutic agents for cardiovascular diseases.
• Further rigorous clinical trials, specifically randomized placebo-controlled studies, are essential to validate their efficacy in humans.
