Several new 3-formylchromone derivatives proved to be modifiers of multidrug resistance in mouse lymphoma cells and in human Colo320 colon cancer cells. There is apparently a structure-activity relationship between the antiproliferative multidrug resistance-reversing effect and the chemical structure of the 3-formylchromones. The total polar surface areas and the ground state dipole moments of the molecules are presumed to play a key role in the multidrug resistance-reversing effect. The log P values can provide an adequate explanation for the selective cytotoxicity against cancer cells.
