Synthesis of condensed quinolines and quinazolines as DNA ligands
摘要:
Among new condensed quinolines and quinazolines the design of which were inspired by anti-cancer DNA-binding alkaloids such as camptothecin and batracyclin, DNA binding tests identify the 8-methoxy-7-piperazinylpropoxyindeno[1,2-b]quinolin-II-one tetracyclic system as a new motif for DNA recognition.

The present invention provides compounds of formula (I): ##STR1## wherein R.sub.1 -R.sub.7, W, X, Y, and Z have any of the values defined in the specification, and pharmaceutically acceptable salt thereof, that are are useful as anticancer agents. Also disclosed are pharmaceutical compositions comprising one or more compounds of formula I, processes for preparing compounds of formula I, and intermediates useful for preparing compounds of formula I.

benz[a]acridine and benz[c]acridinederivatives were synthesized and their relative activity as topoisomerase poisons was determined. While the benz[c]acridinederivatives evaluated as part of this study were devoid of topoisomerase poisoning activity, several dihydrobenz[a]acridines were able to enhance DNA cleavage in the presence of topo I. In contrast to certain protoberberine derivatives that did
