Potential Therapeutic Appliances of Dietary Polyphenols: Resveratrol and Curcumin in Treatment of Gliomas.

Plant-derived polyphenols have become a subject of scientific interest in recent decades due to their widespread occurrence in dietary sources and multi-faceted biological activity, with many of these compounds being recognized as antioxidants and anti-inflammatory agents. Several of these chemicals have, moreover, attracted further interest as their anti-tumoral capabilities were discovered, promising potential implementation in the treatment of proliferative diseases, including various cancers. Malignancies of the central nervous system, the most prevalent of which are glioblastomas, are noted for their aggressiveness, dismal prognosis and low survival rates. This review focuses on two polyphenols with the most expansive body of research on this topic, namely resveratrol and curcumin. It covers recent developments in the research, including in vitro findings, animal model studies and clinical trials on these compounds' effects on the growth and progression of glial tumors of the central nervous system. Its aim is to present the latest findings on the subject of the mechanisms of action of these phytochemicals and their synergistic activity with conventional therapies, as well as strategies to improve their efficacy for future therapeutic applications.
