Reversan is primarily used in the field of medical research and pharmacology due to its ability to modulate multidrug resistance (MDR) in cancer cells. It functions as a multidrug resistance-associated protein 1 (MRP1) inhibitor, which helps in reversing the resistance of cancer cells to various chemotherapeutic agents. By blocking the efflux of drugs from cancer cells, Reversan enhances the intracellular concentration of chemotherapeutic drugs, thereby increasing their efficacy. This makes it a valuable tool in improving the outcomes of cancer treatments, particularly in cases where drug resistance has become a significant challenge. Additionally, Reversan is utilized in laboratory studies to better understand the mechanisms of drug resistance and to develop new strategies to overcome it in clinical settings.
