synthetic antileukemic drug amsacrine) has been synthesized. Their DNA binding properties were determined and discussed in terms of their structural differences and in relation to their observed base-dependent binding. Binding data are consistent with a model in which the acridine nucleus occupies an intercalation site and the netropsin or distamycin residue resides in the DNA minor groove. Cytostatic
合成了一组假肽,天然抗肿瘤剂双歧霉素或netropsin与苯胺基r啶发色团(与合成的抗白血病药物氨茶碱有关)的分子组合。确定并讨论了它们的DNA结合特性,并讨论了它们的结构差异以及与观察到的碱基依赖性结合。结合数据与模型一致,在模型中the啶核占据一个插入位点,而netropsin或distamycin残基位于DNA小沟中。报道了针对鼠细胞系的细胞抑制活性和细胞毒性活性,以及对DNA合成的抑制作用的显着差异。

A novel sequence-selective extended PBD dimer 4 has been synthesized that binds with high affinity to an interstrand cross-linking site spanning 11 DNA base pairs. Despite its molecular weight (984.07) and length, the molecule has significant DNA interstrand cross-linking potency (approximately 100-fold greater than the clinically used agent melphalan) and sub-micromolar cytotoxicity in a number of
已经合成了新颖的序列选择性扩展的PBD二聚体4,其以高亲和力结合跨越11个DNA碱基对的链间交联位点。尽管其分子量(984.07)和长度,该分子在许多肿瘤细胞系中仍具有显着的DNA链间交联能力(比临床使用的药物melphalan约大100倍)和亚微摩尔的细胞毒性,这表明它很容易穿透细胞膜和核膜以达到其DNA靶标。
