Series of structurally varied N-alkyl 1,4-dihydropyridines and novel benzo-annelated derivatives as 1,4- dihydroquinolines have been characterized as ABCB1 inhibitors. Structure-activity relationships (SARs) are discussed. Cytotoxic activities of selected compounds have been determined. A first bioanalysis of ABCB1 substrate properties has been carried out in a cell-based model. Compounds with highest ABCB1 inhibiting activities were no substrates of ABCB1 and not transported by the efflux pump, thus profiling the new ABCB1 inhibitors.
