A series of novel water-soluble β-carbolines bearing a flexible amino side chain was designed, synthesized and evaluated as potent cytotoxic and DNA intercatalating agents. The N9-arylated alkyl substituted β-carbolines represented the most interesting cytotoxic activities. The results suggested that (1) the N9-arylated alkyl substituents of β-carboline nucleus played a very important role in the modulation of the cytotoxic potencies; (2) the length of the alkylamino side chain significantly affected their cytotoxic potency, and N,N-dimethylaminopropylamino substituent were more favorable. In addition, these compounds were found to exhibit significant DNA intercalating potencies.
设计、合成了一系列带有柔性
氨基侧链的新型
水溶性 β-咔啉,并作为有效的细胞毒性剂和 DNA 嵌入剂进行了评估。 N9-芳基化烷基取代的β-咔啉代表了最有趣的细胞毒性活性。结果表明:(1)β-咔啉核上的N9-芳基化烷基取代基在细胞毒效力的调节中发挥着非常重要的作用; (2)烷基
氨基侧链的长度显着影响其细胞毒效力,且N,N-二甲基
氨基丙
氨基取代基更有利。此外,这些化合物被发现表现出显着的 DNA 嵌入能力。
