Abstract:
One of the major problems in chemotherapy is multidrug resistance (MDR) against anticancer drugs. ATP-binding cassette (ABC) transporters are a family of proteins that mediate MDR via ATP-dependent drug efflux pumps. Many MDR inhibitors have been identified, but none of them have been proven clinically useful without side effects. Efforts continue to discover not toxic MDR inhibitors which lack pharmacokinetic interactions with anticancer drugs. Novel approaches have also been designed to inhibit or circumvent MDR. In this review, the structure and function of ABC transporters and development of MDR inhibitors are described briefly including various approaches to suppress MDR mechanisms.
Insights
Multidrug resistance (MDR) in chemotherapy involves ATP-binding cassette (ABC) transporters. This review covers MDR inhibitors and novel strategies to overcome drug resistance, aiming for effective and safe anticancer treatments.
Area of Science:
- Biochemistry
- Pharmacology
- Oncology
Background:
- Multidrug resistance (MDR) is a significant challenge in cancer chemotherapy, limiting treatment efficacy.
- ATP-binding cassette (ABC) transporters facilitate MDR by pumping anticancer drugs out of cells.
- Current MDR inhibitors often cause side effects or have pharmacokinetic interactions with chemotherapy drugs.
Purpose of the Study:
- To review the structure and function of ABC transporters in mediating MDR.
- To discuss the development of novel MDR inhibitors.
- To explore various strategies for suppressing MDR mechanisms in cancer treatment.
Main Methods:
- Literature review of scientific publications on ABC transporters and MDR.
- Analysis of existing and emerging MDR inhibitor research.
- Synthesis of information on different approaches to overcome MDR.
Main Results:
- ABC transporters are key mediators of MDR through ATP-dependent drug efflux.
- Development of MDR inhibitors faces challenges with clinical utility and side effects.
- Novel strategies are being investigated to inhibit or circumvent MDR.
Conclusions:
- Understanding ABC transporter function is crucial for developing effective MDR therapies.
- Continued research is needed to discover non-toxic MDR inhibitors with minimal drug interactions.
- Innovative approaches are essential to overcome MDR and improve chemotherapy outcomes.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
