An efficient synthetic method for 1,8-dioxo-decahydroacridines derivatives bearing the biologically active sulfonamide moiety is described. Aromatic aldehyde reacted with 5,5-dimethyl-1,3-cyclohexanedione and sulfanilamide, with molecular iodine as catalyst, to give 1,8-dioxo-decahydroacridines derivatives in high to excellent yield. The structures of these compounds were established on the basis of elemental (C, H and N) and spectral analysis (1H NMR, 13C NMR, MS and FTIR). All the compounds were tested for their cytotoxic activity in vitro against three human tumor cell lines: human mammary cancer cells (MCF-7), human cervical carcinoma cells (Hela), and human lung cancer cells (A549) by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Most of them showed moderate to potent cytotoxic activity against the tested cell lines. Among them, the most active compound 4e exhibited more efficient activity (10.92 μM) against MCF-7 cells than cisplatin (11.06 μM).
