AbstractOverexpression of ATP-binding cassette (ABC) transporters in cancer cells results in multidrug resistance (MDR) which leads to unsuccessful chemotherapy. The most important MDR-associated members of ABC superfamily are ABC B1/P-glycoprotein/MDR1, ABC C1/multidrug resistance associated protein 1 (MRP1), and ABC G2/BCRP. This study is not only focused on function, substrates, and localization of these popular proteins but also on other ABC C family members such as ABC C2–6/MRP2-6 and ABC C7/CFTR. Current research is mainly oriented on the cancer-promoting role of these proteins, but important lessons could also be learned from the physiological roles of these proteins or from polymorphisms affecting their function. Thorough knowledge of structure and detailed mechanism of efflux can aid in the discovery of new chemotherapy targets in the future. Although the best way on how to deal with MDR would be to prevent its development, we describe some new promising strategies on how to conquer both inherited and induced MDRs.

Multidrug resistance (MDR) in cancer is one of the main limitations for chemotherapy success. Numerous mechanisms are behind the MDR phenomenon wherein the overexpression of the ATP-binding cassette (ABC) transporter proteins P-glycoprotein (P-gp), breast cancer resistance protein (BCRP) and multidrug resistance protein 1 (MRP1) is highlighted as a prime factor. Natural product-derived compounds are being addressed as promising ABC transporter modulators to tackle MDR. Flavonoids and terpenoids have been extensively explored in this field as mono or dual modulators of these efflux pumps. Nitrogen-bearing moieties on these scaffolds were proved to influence the modulation of ABC transporters efflux function. This review highlights the potential of semisynthetic nitrogen-containing flavonoid and terpenoid derivatives as candidates for the design of effective MDR reversers. A brief introduction concerning the major role of efflux pumps in multidrug resistance, the potential of natural product-derived compounds in MDR reversal, namely natural flavonoid and terpenoids, and the effect of the introduction of nitrogen-containing groups are provided. The main modifications that have been performed during last few years to generate flavonoid and terpenoid derivatives, bearing nitrogen moieties, such as aliphatic, aromatic and heterocycle amine, amide, and related functional groups, as well as their P-gp, MRP1 and BCRP inhibitory activities are reviewed and discussed.
