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).
本研究描述了一种具有生物活性磺酰胺分子的 1,8-二氧代十氢吖啶衍生物的高效合成方法。在分子碘作为催化剂的作用下,芳香醛与 5,5-二甲基-1,3-环己二酮和磺胺发生反应,得到 1,8-二氧代十氢吖啶衍生物,收率高至极佳。这些化合物的结构是根据元素分析(C、H 和 N)和光谱分析(1H NMR、13C NMR、MS 和 FTIR)确定的。通过 3-(4,5-二甲基噻唑-2-基)-2,5-二苯基溴化四氮唑(MTT)测定法,对所有化合物对三种人类肿瘤细胞系(人类乳腺癌细胞(MCF-7)、人类宫颈癌细胞(Hela)和人类肺癌细胞(A549)的细胞毒活性进行了体外测试。大多数化合物对受试细胞株都显示出中等至强效的细胞毒性活性。其中,活性最强的化合物 4e 对 MCF-7 细胞的活性(10.92 μM)高于顺铂(11.06 μM)。
