Novel benzimidazolium bromides salts having (4-methoxyphenyl)ethyl, (phthalimide-2-yl)methyl, 4-nitro- benzyl, 2-phenylethyl, penthyl, or allyl groups were synthesized and their characterizations were conducted by $^1}$H and $^13}$C NMR and IR spectroscopic methods, and microanalysis. In vitro antitumor activities of the novel benzimidazole compounds (1-7) were determined by using ovarian (A2780) and prostate (PC-3) cancer cell lines. Antitumor properties of all compounds were determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. A time-dependent cell viability assay for the tested benzimidazole compounds was performed and the IC$_50}$ values of the compounds were calculated after treatment for 24 and 48 h. Our results indicate that the tested benzimidazole compounds show antitumor activity against A2780 and PC-3 cell lines (P $
合成了具有(4-甲氧基苯基)乙基、(邻苯二甲酰亚胺-2-基)甲基、4-硝基苄基、2-苯基乙基、戊基或烯丙基基团的新型苯并咪唑溴化物盐,并通过 $^1}$H 和 $^13}$C NMR 和 IR 光谱法以及显微分析法对其进行了表征。利用卵巢癌(A2780)和前列腺癌(PC-3)细胞系测定了新型苯并咪唑化合物(1-7)的体外抗肿瘤活性。所有化合物的抗肿瘤特性均通过 3-(4,5-二甲基噻唑-2-基)-2,5-二苯基溴化四氮唑(MTT)测定法确定。结果表明,受试苯并咪唑化合物对 A2780 和 PC-3 细胞株具有抗肿瘤活性(P $_50}$)。
