从色醇出发,通过Sharpless环氧化、酰胺化、偶联和成盐四步反应合成了一系列新型的吲哚并四氢呋喃-咪唑盐杂合物,其结构经1H NMR,13C NMR,HRMS以及X射线单晶衍射确定.对合成的新化合物进行了体外抗肿瘤细胞毒活性筛选,结果表明,1-((3aR,8aS)-3,3a-二氢-3a-羟基-2H-呋喃并[2,3-b]吲哚-8(8aH)-基)乙酮-3-(2-(萘-2-基)-2-氧乙基)-5,6-二甲基-1H-苯并[d]咪唑-3-溴盐(20)和1-((3aR,8aS)-3,3a-二氢-3a-羟基-2H-呋喃并[2,3-b]吲哚-8(8aH)-基)乙酮-3-(2-萘甲基))-5,6-二甲基-1H-苯并[d]咪唑-3-溴盐(22)具有较好的体外肿瘤生长抑制活性,对SMMC-7721、MCF-7和SW-480肿瘤细胞株的活性均优于顺铂(DDP),1-((3aR,8aS)-3,3a-二氢-3a-羟基-2H-呋喃并[2,3-b]吲哚-8(8aH)-基)乙酮-3-(2-溴苄基))-5,6-二甲基-1H-苯并[d]咪唑-3-溴盐(24)对SW-480肿瘤细胞株表现出较好的选择性细胞毒活性,其IC50值约为顺铂的2.0倍.

A series of novel hybrid compounds between indolo[b]tetrahydrofuran and imidazolium salts were prepared from tryptophol by four steps of Sharpless epoxidation, amidation, coupling and salt formation. Their structures were confirmed by 1H NMR, 13C NMR, HRMS and X-ray crystallographic analysis. These compounds were evaluated in vitro against a panel of human tumor cell lines. The results showed that 1-((3aR,8aS)-3,3a-dihydro-3a-hydroxy-2H-furo[2,3-b]indol-8(8aH)-yl)etha-none-3-(2-(naphthalen-2-yl)-2-oxoethyl)-5,6-dimethyl-1H-benzo[d]-imidazol-3-ium bromide (20) and 1-((3aR,8aS)-3,3a-di-hydro-3a-hydroxy-2H-furo[2,3-b]indol-8(8aH)-yl)ethanone-3-(2-naphthylmethyl)-5,6-dimethyl-1H-benzo[d]imidazol-3-ium bromide (22) exhibited higher inhibitory activity selectively against SMMC-7721, MCF-7 and SW480 cell lines compared with DDP. In particular, 1-((3aR,8aS)-3,3a-dihydro-3a-hydroxy-2H-furo[2,3-b]indol-8(8aH)-yl)ethanone-3-(2-bromobenzyl)-5,6-dimethyl-1H-benzo[d]imidazol-3-ium bromide (24) was more selective to SW-480 cell lines with IC50 values 2.0-fold lower than DDP.
