Reversal of Multidrug Resistance in Murine Lymphoma Cells by Amphiphilic Dihydropyridine Antioxidant Derivative
Multidrug resistance, the principal mechanism by which cancer cells develop resistance to chemotherapy drugs, is a major factor in the failure of many forms of chemotherapies. The aim of the study was to investigate the effect of K-2-11 on the reversal of multidrug resistance. The effects of amphiphilic dihydropyridine derivative K-2-11 were tested on MDR1-expressing mouse lymphoma cells and their parental control. The effects of K-2-11 with and without doxorubicin were studied by determination of cell viability, cell proliferation and production of reactive oxygen species. K-2-11 caused complete reversal of multidrug resistance of the MDR cells, being much more efficient than the positive control verapamil. Accordingly, the cytotoxic effects of doxorubicin were enhanced by K-2-11, both in the MDR and in parental cell line, while K-2-11 alone did not affect cell viability. K-2-11 also acted as an antioxidant, reducing the cellular generation of reactive oxygen species. Our results indicate the high potential of K-2-11 as a novel antioxidant with potent MDR-blocking ability that should be studied further for development in adjuvant anticancer treatments.
