  The present invention describes reagents and methods for using a concatemerized double-stranded oligonucleotide molecules (CODN) for transcription factor decoys. In one embodiment, the concatemers consist of a variable number of end-to-end repeated copies of a short (more than 5, 10, 15, 20, 2, 3035, 40, 45, 50, 75, 100, or more by but generally less than about 3 kb) dsDNA containing a sequence or sequences that act as transcription factor decoys. The present invention also provides for the use of the polymers for CODN/polymer complexes to a specific cell type; thus the agent can be made organ, tissue and/or cell-type specific. In another embodiment, the present invention provides for use of the CODN's in vitro or in vivo, in isolated cells or intact animals in which specific blockade of transcription factors or delivery of DNA or other biological effector is desirable. In one embodiment, this includes use as a research tool, including studies of specific genes and studies to identify specific genes regulated by the transcription factors targeted. In another embodiment, the present invention provides for using polyamides for NF-kB-specific CODN delivery in the treatment of myocardial ischemia/reperfusion and myocardial infarction, heart failure and hypertrophy, cardioprotection, stroke, neuroprotection, sepsis, arthritis, asthma, heritable inflammatory disorders, cancer, heritable immune dysfunctions, inflammatory processes, whether caused by disease or injury or infection, oxidative stress to any organ whether caused by disease, surgery or injury. The decoys may be any transcription factors, including, but not limited to, NF-kB, AP-I, ATF2, ATF3, SP 1 and others.

  本发明描述了一种使用串联双链寡核苷酸分子（CODN）作为转录因子诱饵的试剂和方法。在一种实施例中，串联体由一种短的（大于5、10、15、20、25、30、35、40、45、50、75、100或更多，但通常小于约3 kb）双链DNA的端对端重复拷贝构成，其中包含作为转录因子诱饵的一个或多个序列。本发明还提供了将聚合物用于CODN/聚合物复合物对特定细胞类型的使用；因此，该试剂可以被制成特定的器官、组织和/或细胞类型。在另一种实施例中，本发明提供了在离体或体内、在孤立的细胞或完整的动物中使用CODN的方法，其中需要特定的转录因子阻断或DNA或其他生物效应物的递送。在一种实施例中，这包括用作研究工具，包括研究特定基因和研究识别被靶向的转录因子调控的特定基因。在另一种实施例中，本发明提供了使用聚酰胺进行NF-kB特异性CODN递送，用于治疗心肌缺血/再灌注和心肌梗死、心力衰竭和肥厚、心脏保护、中风、神经保护、败血症、关节炎、哮喘、遗传性炎症性疾病、癌症、遗传性免疫功能障碍、炎症过程，无论是由疾病、手术还是损伤或感染引起的，以及对任何器官的氧化应激。诱饵可以是任何转录因子，包括但不限于NF-kB、AP-I、ATF2、ATF3、SP1等。

• Polycationic β-Cyclodextrin “Click Clusters”:  Monodisperse and Versatile Scaffolds for Nucleic Acid Delivery
  作者：Sathya Srinivasachari、Katye M. Fichter、Theresa M. Reineke

  DOI：10.1021/ja074597v

  日期：2008.4.1

  Herein, a novel series of multivalent polycationic beta-cycloclextrin "click clusters" with discrete molecular weight have been synthesized, characterized, and examined as therapeutic pDNA carriers. The materials were creatively designed based on a beta-cyclodextrin core to impart a biocompatible multivalent architecture and oligoethyleneamine arms to facilitate pDNA binding, encapsulation, and cellular uptake. An acetylated-per-azido-beta-cyclodextrin (4) was reacted with series of alkyne dendrons (7a-e) (containing one to five ethyleneamine units) using copper-catalyzed 1,3-dipolar cycloaddition, to form a series of click clusters (9a-e) bearing 1,2,3-triazole linkers. Gel electrophoresis experiments, dynamic light scattering, and transmission electron microscopy revealed that the macromolecules bind and compact pDNA into spherical nanoparticles in the size range of 80-130 nm. The polycations protect pDNA against nuclease degradation, where structures 9c, 9d, and 9e did not allow pDNA degradation in the presence of serum for up to 48 h. The cellular uptake profiles were evaluated in Opti-MEM and demonstrate that all the click clusters efficiently deliver Cy5-labeled pDNA into HeLa and H9c2 (2-1) cells, and compounds 9d and 9e yielded efficacy similar to that of the positive controls, Jet-PEI and Superfect. Furthermore, the luciferase gene delivery experiments revealed that the level of reporter gene expression increased with an increase in oligoethyleneamine number within the cluster arms. The cytotoxicity profiles of these materials were evaluated by protein, MTT, and LDH assays, which demonstrate that all the click clusters remain nontoxic within the expected dosage range while the positive controls, Jet PEI and Superfect, were highly cytotoxic. In particular, 9d and 9e were the most effective and promising polycationic vehicles to be further optimized for future systemic delivery experiments.

  The present invention provides a new class of non-viral transduction vectors that can be used for both in vivo and in vitro applications. The present invention also provides a gene transfer vector that has comparable efficiency to a viral vector without the potential for a life-threatening immune response. Complexes according to the invention or portions thereof, can comprise a cellular delivery molecule or agent that can facilitate the translocation of the complex or portion thereof into cells. In some embodiments, cellular delivery molecules for use in the present invention may comprise one or more polymers of the present invention, e.g., polyamides, dendritic macromolecules and carbohydrate-containing degradable polyesters.
