BACKGROUND
Hydantoin derivatives possess a variety of biochemical and pharmacological properties. Although hydantoin compounds are studied extensively, there are not many studies that investigate their anticancer properties.
METHODS
Thirty hydantoin compounds were evaluated for their efflux

BACKGROUND
Hydantoin derivatives are very promising candidates to improve the efficacy of anticancer chemotherapy. Previously, we demonstrated that eight hydantoin derivatives inhibited the P-glycoprotein (ABCB1) efflux pump of mouse T-lymphoma cells, as well as acting synergistically with the
