The total synthesis of Ardisinone E [15, 1-(2,4,6-trihydroxy phenyl)-11-(2-hydroxyphenyl)-undecan-1-one], a natural diarylundecanone, isolated from Ardisia arborescens, was accomplished along with 16 new diarylundecanone analogs (18a–p), by modified Wittig reaction. The structures of the compounds were confirmed by 1H, 13C and mass spectral data. Compound 15 showed potent cytotoxic activity with an
Ardisinone E [总合成15 1-(2,4,6-三羟基-苯基)-11-(2-羟基苯基)-undecan -1-酮],天然diarylundecanone,分离自朱砂藜,用沿完成通过改良的Wittig反应,得到16种新的二芳基十一烷酮类似物(18a – p)。化合物的结构由1 H,13 C和质谱数据证实。在盐水虾致死率测定模型中,化合物15显示出强的细胞毒性,ED 50为4.19 µg / mL。化合物18c,18e,18j,18k,18l和在NBT自由基测定中,18m具有很强的抗氧化活性,IC 50值分别为18.75、12.28、18.35、11.04、12.05和11.32 µg / mL。化合物18e,18k和18m还显示出显着的5-脂氧合酶抑制潜力,IC 50值分别为12.8、15.23和15.23 µg / mL。
