Therapeutic Potential of Plant Phenolic Acids Combating Cancer Drug Resistance

Despite notable progress in treatment modalities, cancer continues to be a prom-inent cause of death globally. Chemotherapy is the main method used to treat cancer, and chemotherapeutic medications are categorized according to how they work. Nevertheless, the issue of multidrug resistance (MDR) is a significant obstacle, impacting almost 90% of cancer patients who receive chemotherapy or innovative targeted medicines. MDR pro-cesses involve the quick metabolism of foreign substances, the accelerated removal of drugs from cells, the stimulation of growth hormones, the enhancement of DNA repair ability, and the influence of genetic variables. Recent studies have mostly concentrated on studying the anticancer effects of dietary phytoconstituents as a possible remedy for overcoming multidrug resistance (MDR). Various bioactive compounds, such as phenolic acids, phe-nylpropanoids, flavonoids, stilbenes, terpenoids, and organo-sulfur compounds, have shown potential in fighting cancer. It is worth mentioning that a number of phenylpro-panoids are now being tested in clinical trials to evaluate their effectiveness in fighting cancer. This review presents a comprehensive summary of the existing knowledge regard-ing dietary phytoconstituents as possible agents for treating cancer, particularly their ability to overcome MDR. This discussion will focus on the mechanisms by which these com-pounds work, as well as the data from both preclinical and clinical studies. Additionally, we have explored the potential future applications of these compounds in the development of cancer therapeutics.
