A series of novel hybrid compounds between tricyclic indeno[5,6-b]furan and imidazole has been prepared and
evaluated in vitro against a panel of human tumor cell lines. The results suggest that the existence of benzimidazole ring
and substitution of the imidazolyl-3-position with a naphthylacyl group were vital for modulating cytotoxic activity. In
particular, hybrid compound 26 was found to be the most potent compound against 5 strains human tumor cell lines and
more active than cisplatin (DDP), while compound 18 was more selective towards breast carcinoma (MCF-7) and colon
carcinoma (SW480) with IC50 value 3.4-fold and 4.3-fold more sensitive to DDP.
一系列新颖的杂化化合物,介于三环吲哚[5,6-b]呋喃和咪唑之间,已被制备并针对一组人类肿瘤细胞系进行了体外评估。结果表明,苯并咪唑环的存在以及咪唑-3-位被萘基酰基团取代对于调节细胞毒性活性至关重要。特别是,杂化化合物26被发现是针对5种人类肿瘤细胞系中最有效的化合物,且比顺铂(DDP)更活跃,而化合物18对乳腺癌(MCF-7)和大肠癌(SW480)更具选择性,其IC50值比DDP敏感3.4倍和4.3倍。
