Multi-target agents against tyrosine kinases and topoisomerases are potentially useful for the effective treatment of cancers. Discovery of new multi-target scaffolds are important for developing such agents. A series of five novel acridine analogues, LXL 1–5, were synthesized and their antiproliferative activity against HepG-2 cell lines were evaluated, among which the 9-benzyloxyacridine analogue, LXL-5, showed inhibitory activity against ...
