Abstract

Background: Overcoming multidrug resistance (MDR), which is often caused by the overexpression of ATP binding cassette (ABC) transporters in cancer cells remains a major challenge for cancer treatment. Receptor tyrosine kinase inhibitors have demonstrated potential in reversing MDR. This study aimed to investigate the effects of c-MET RTKIs on the reversal of MDR induced by ABCG2 in breast cancer cells.

Methods: MTT assay was employed to assess antiproliferative activity of c-MET inhibitors, including cabozantinib, crizotinib, and PHA665752. The accumulation of the fluorescent probe mitoxantrone was evaluated by flow cytometry. The drug-drug interaction in combination treatments was analyzed using CalcuSyn software.

Results: The combination of cabozantinib, crizotinib, and PHA665752 with mitoxantrone resulted in synergistic effects in MDR cells. This was demonstrated by the mean CI values of 0.32 ± 0.07, 0.53 ± 0.05, and 0.59 ± 0.03, respectively. In the same cells, c-MET inhibitors enhanced the accumulation of mitoxantrone, with accumulation ratios ranging from 1.6 to 3.8, while no change was found in parental MCF-7 cells. Computational analysis revealed that the drug-binding region of ABCG2 transporters could be a viable target for these compounds.

Conclusion: c-MET inhibitors hold potential as effective agents for reversing MDR in ABCG2-medicated drug-resistant cancer cells.

期刊介绍: JPP keeps pace with new research on how drug action may be optimized by new technologies, and attention is given to understanding and improving drug interactions in the body. At the same time, the journal maintains its established and well-respected core strengths in areas such as pharmaceutics and drug delivery, experimental and clinical pharmacology, biopharmaceutics and drug disposition, and drugs from natural sources. JPP publishes at least one special issue on a topical theme each year.
