Synthesis and Biological Evaluation of Novel Acenaphthene Derivatives as Potential Antitumor Agents

Twelve novel acenaphthene derivatives have been synthesized. The structures of all compounds were confirmed by 1H-NMR, MS and elemental analysis. Their antitumor activities were evaluated in six human solid tumor cell lines, namely non-small cell lung cancer (H460), human colon adenocarcinoma (SW480), human breast cancer cell (MDA-MB-468 and SKRB-3), human melanoma cell (A375) and human pancreatic cancer (BxPC-3) . Among them, compound 3c shows the best antitumor activity against SKRB-3 cell line, as high as the positive control adriamycin.
