synthesis, and biological investigation of novel antimalarial agents with low potential to develop resistance and structurally based on a highly conjugated scaffold. Starting from a new hit, the designed modifications were performed hypothesizing a specific interaction with free heme and generation of radical intermediates. This approach provided antimalarials with improved potency against chloroquine-resistant
A series of N1-arylidene-N2-quinolyl- and N2-acrydinylhydrazones were synthesized and tested for their antimalarial properties. These compounds showed remarkable anti-plasmodial activity in vitro especially against chloroquine-resistant strains. Their potent biological activity makes them promising lead structures for the development of new antimalarial drugs. (c) 2006 Elsevier Ltd. All rights reserved.
