A new series of ellipticine derivatives, 1-(alkylamino)-5,11-dimethyl-9-methoxy-6H-pyrido[4,3-b]carbazoles, were synthesized as potential DNA intercalating antitumor drugs. The structure of these compounds were confirmed by 1H NMR spectroscopy and mass spectrometry. These compounds are able to bind to DNA with an affinity of about 10(6) M-1, and their intercalating characteristics (lengthening and
合成了一系列新的玫瑰树碱衍生物1-(烷基氨基)-5,11-二甲基-9-甲氧基-6H-吡啶并[4,3-b]咔唑,作为潜在的DNA嵌入抗肿瘤药物。这些化合物的结构通过1 H NMR光谱和质谱确认。这些化合物能够以约10(6)M-1的亲和力与DNA结合,其嵌入特性(DNA的延长和解旋)取决于位置1上链的长度。这些化合物对L1210的细胞毒性与NIH-3T3细胞非常相似,荧光技术表明该化合物主要定位于细胞的细胞质颗粒中。这些化合物之一似乎显示出很高的抗肿瘤活性(相当于活性更高的玫瑰树碱类似物:
