The synthesis and biological activities of representatives of a new class of antitumor agent, the N-[2-(dialkylamino)ethyl ]-9-aminoacridine-4-carboxamides, are reported. Members of this class are stable and very water soluble with high levels of in vitro and in vivo antitumor activity. The compounds bind tightly to double-stranded DNA by intercalation, but the requirements for antitumor activity are

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 IC50 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. (C) 2008 Elsevier Ltd. All rights reserved.
