Role of Polyphenols and Flavonoids as Anti-Cancer Drug Candidates: A Review

Natural drug-based chemotherapeutic have advanced at an unprecedented rate over the past decade. Owing to protective roles in vegetation, and exceptional antioxidant qualities, polyphenols and flavonoids have demonstrated promising clinical implications in malignancies amongst other plant metabolites. It is widely debated how dietary flavonoids and polyphenols can prevent cancer. Flavonoids are believed to execute a significant role in cancer prevention and treatment, as corroborated from experimental studies, epidemiological research, and human clinical trials. Carcinogen deactivation, antimutagenic, cell cycle arrest, apoptosis and differentiation, suppression of vasculature, oxidative stress, and reversion of multidrug resistance are among the many mechanisms of action that have been discovered. The present review outlines the classification of various polyphenols and flavonoids and their potential as anticancer therapeutic agents.
