Synthesis, Structure and Cytotoxic Activity of Mono- and Dialkoxy Derivatives of 5,8-Quinolinedione.


ABSTRACT: A series of 5,8-quinolinedione derivatives containing one or two alkoxy groups was synthesized and characterized by ¹H- and (13)C-NMR, IR and MS spectra. X-ray diffraction was used to investigate the crystal structures of 6-chloro-7-(2-cyjanoethoxy)-5,8-quinolinedione and 6,7-di(2,2,2-trifloroethoxy)-5,8-quinolinedione. All studied compounds were tested in vitro for their antiproliferative activity against three human cancer cell lines and human normal fibroblasts. Most of the compounds showed higher cytotoxicity than the starting compound, 6,7-dichloro-5,8-quinolinedione, and cisplatin, which was used as a reference agent.
