Abstract
We describe the synthesis of a series of DNA-threading bis(9-aminoacridine-4-carboxamides) comprising ethylpiperidino and N-methylpiperidin-4-yl sidechains, joined via neutral flexible alkyl chains, charged flexible polyamine chains and a semi-rigid charged piperazine linker. Their cytotoxicity towards human leukaemic cells gives IC(50) values ranging from 99 to 1100 nM, with the ethylpiperidino series generally being more cytotoxic than the N-methylpiperidin-4-yl series. Measurements with supercoiled DNA indicate that they bisintercalate.
