Lithium–halogen exchange of 2,4-dibromoquinolines proceeds regioselectively at C-4 and affords 4-substituted quinolines on quenching with electrophiles. Palladium-catalyzed cross-coupling reactions of 2-bromo-4-iodoquinoline provide 4-substituted 2

Two pleiotropic multi-drug resistant (PDR) KB cell lines were hypersusceptible to a cytotoxic extract from Fatsia japonica. Fractionation of an active extract using a cell-based assay for DNA topoisomerase inhibitors led to the isolation of three kno

Many tannins were previously identified as candidate topoisomerase poisons. Here we report further studies on sanguiin H-6, a dimeric ellagitannin isolated from Sanguisorba officinalis as an inhibitor of DNA topoisomerases. Catalytic strand-passing a

Two colchicine derivatives gave dose-dependent cytocidal effects in human osteogenic sarcoma cells. Unlike colchicine, the analogues stimulated formation of intacellular protein-linked DNA breaks, they inhibited DNA topoisomerase II in vitro, and the
