摘　　要：从胡椒酸出发,通过还原、甲磺酸酯化、偶联和成盐四步反应合成了-系列新型的胡椒基咪唑盐类化合物,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-((苯并[d][1,3]二氧杂环戊烯-5-基甲基)-3-(2-萘甲基))-5,6-二甲基-1H-苯并[d]咪唑-3-溴盐(30)具有显著的细胞毒活性,对HL-60、SMMC-7721、A-549、MCF-7和SW-480肿瘤细胞株的活性均优于顺铂(DDP),尤其对HL-60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7.2倍.进一步研究表明,化合物30具有诱导SMMC-7721细胞株在细胞周期G0/G1期阻滞和细胞凋亡的作用.A series of novel hybrid compounds between piperonyl and imidazolium salts were prepared from tryptophol by four steps of reduction,mesylation,coupling and salt formation.Their structures were confirmed by'H 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 l-((benzo[d][l,3]dioxol-5-ylmethyl)-3-(2-naphthylmethy 1))-5,6-dimethyl-lH-benzo[[d]imidazol-i3u-m bromide(30)exhibited remarkable inhibitory activity selectively against HL-60,SMMC-7721,A-549,MCF-7 and SW480 cell lines compared with DDP.In particular,the compound was more selective to HL-60 cell lines with IC50 values f7o.2ld-lower than DDP.Further studies showed that compound 30 has the effect of inducing SMMC-7721 cell line arrest and cell apoptosis in cell cycle G0/G1.
