  末端甲酰胺基团对聚酰胺对 DNA 序列识别的影响

  摘要：

  含有吡咯 (Py)-咪唑 (Im) 的聚酰胺结合在 DNA 的小沟中，可以通过堆叠的反平行二聚体识别特定序列。已经提出有两种不同的低能量方式来形成堆叠的二聚体，并且它们对末端甲酰氨基的存在很敏感：（i）完全重叠的堆叠模式，其中二聚体的 N 端杂环堆叠在 C 端两个杂环之间的酰胺基团上和 (ii) 交错堆叠模式，其中 N 端杂环在 C 端方向上移动大约一个单位（结构 1997, 5, 1033-1046） . 两种不同的 DNA 序列将被以这两种不同模式堆叠的相同聚酰胺识别。尽管聚酰胺作为序列特异性 DNA 识别剂的重要性，尚未系统地探索这些堆叠的可能性。作为开发可识别 DNA 中错配碱基对的试剂的计划的一部分，合成了一组具有和不具有末端甲酰胺基团的四个聚酰胺三聚体，并评估了它们与两种不同堆叠模式下预测的 DNA 识别序列的相互作用。通过使用表面等离子体共振 (SPR) 检测与固定化 DNA

  DNA minor groove binder hybrid molecules, netropsin derivatives such as N-[2-(dimethylamino)ethyl]-1-methyl-4-aminopyrrolo-2-carboxamide (MePy) or its derivatives containing two units of N-methylpyrrolecarboxamide (diMePy) and bisbenzimidazole (Ho33258), were linked to the NH2 function of AHMA or to the CH2OH group of AHMA-ethylcarbamate to form AHMA-N-netropsins (13-16) and AHMA-ethylcarbamate-O-netropsins (19-22), and AHMA-bis-benzimidazole (AHMA-Ho33258, 25), respectively. These conjugates' in vitro antitumor activity, inhibition of a variety of human tumor cell growth, revealed that AHMA-ethylcarbamate-O-netropsin derivatives were more cytotoxic than AHMA-N-netropsin compounds. In the same studies, all compounds bearing MePy were more potent than those compounds linked with diMePy. Moreover, AHMA-netropsin derivatives bearing a succinyl chain as the linking spacer were more potent than those compounds having a glutaryl bridge. Among these hybrid molecules, AHMA-ethylcarbamate-O-succinyl-MePy (19) was 2- to 6-fold more cytotoxic than the parent compound AHMA (5) in various cell lines, whereas compound 25 had very poor solubility and was inactive. Studies on the inhibitory effect against topoisomerase II (Topo II) and DNA interaction of these conjugates showed no correlation between the potency of DNA binding and inhibitory activity against Topo II.
• Antitumor Imidazotetrazines. 41. Conjugation of the Antitumor Agents Mitozolomide and Temozolomide to Peptides and Lexitropsins Bearing DNA Major and Minor Groove-Binding Structural Motifs

  日期：2002.12.1

  Carboxylic acids derived from the amido groups of the antitumor agents mitozolomide and temozolomide have been conjugated to simple amino acids and peptides by carbodiimide coupling. Solid-state peptide synthesis has been applied to link the acids to DNA major groove-binding peptidic motifs known to adopt alpha-helical conformations. Attachment of the acids to pyrrole and imidazole polyamidic lexitropsins gave a series of potential DNA minor groove- binding ligands. In vitro biological evaluation of a limited number of these novel conjugates failed to demonstrate any enhanced growth-inhibitory activity compared to the unconjugated drugs; sites of alkylation at tracts of multiple guanines were also unaffected. Attachment of additional residues at C-8 of the imidazotetrazines did not perturb the chemistry of activation of the bicyclic nucleus, and biological sequelae can be rationalized by invoking the liberation of a common, diffusible, reactive chemical intermediate, the methanediazonium ion.
• Synthesis of a netropsin conjugate of a water-soluble epi -quinocarcin analogue: the importance of stereochemistry at nitrogen
  作者：Brad Herberich、Jack D. Scott、Robert M. Williams

  DOI：10.1016/s0968-0896(99)00314-4

  日期：2000.3

  The efficient synthesis of a water-soluble C11a-epi-analogue (6b) of quinocarcin is described. This substance, and a netropsin amide conjugate (8) lack the capacity to inflict oxidative damage on DNA due to the stereoelectronic geometry of their oxazolidine nitrogen atoms. The capacity of these substances to alkylate DNA through the generation of an iminium species has been examined. Both compounds were found to be unreactive as DNA alkylating agents. The results of this study are discussed in the context of previous proposals on the mode of action of this family of antitumor alkaloids. (C) 2000 Elsevier Science Ltd. All rights reserved.
