项目摘要
DESCRIPTION (provided by applicant): One of the challenges of research in infectious diseases is to find ways to use the increasing knowledge of the mechanisms underlying disease transformation and progression to develop novel therapeutic strategies for diseases such as increasing menace of bacterial infections. Targeting specific RNA, such as rRNA which are involved in proliferation and survival of bacteria is a promising approach. The world is rapidly heading towards a pre-1940's scenario when it comes to fighting infectious disease. Antimicrobial resistance is a growing problem on a global scale, greatly hampering our abilities to quell worldwide epidemics such as tuberculosis and malaria, as well as the simple staphylococcus infection. Unless innovative strategies are developed to produce robust and effective new classes of antibiotics, health care costs will continue to climb and we will completely lose our ability to combat even the most common infection. Nucleic acids are avenues for drug design, both as therapeutics and as targets. Here we propose to establish new methods for identifying antibiotic ribosome targets and lead compounds. We are developing fast and low cost methods to screen sequence-specific small molecules for novel anti-ribosomal activities. We will construct sequence-specific ribosomal targeting oligomers as antibacterials. Complexes between ribosomal components will be exploited as targets for small molecule drug libraries that- inactivate the ribosome, stopping bacterial protein synthesis and causing bacterial
death. NUBADs unique experimental approaches and technologies will allow us to target ribosomal regions not previously explored for susceptibility against anti-bacterial agents. This work addresses an important world health issue, antimicrobial resistance, and presents creative steps towards a novel solution to this problem. The work proposed here, a multidisciplinary effort encompassing solid-phase organic synthesis, RNA targeted screening and antibacterial studies, describes the development of sequence-specific cell permeable binders of rRNA as antibacterial therapeutics. The success of the proposed work would be a significant addition to currently available ribosome-specific approaches in antibacterial therapy. We propose using a small rRNA target sequences to design conjugates that can be employed to inhibit bacterial growth, opening possibilities for developing sequence-specific RNA targeted therapeutics.
描述(由申请人提供):传染病研究的挑战之一是找到方法,利用对疾病转化和进展机制的不断增长的知识来开发新的治疗策略,以治疗诸如细菌感染等威胁日益增加的疾病。靶向特异性RNA,如与细菌增殖和生存有关的rRNA,是一种很有前途的方法。在与传染病作斗争方面,世界正迅速走向20世纪40年代以前的情景。在全球范围内,抗微生物药物耐药性是一个日益严重的问题,极大地阻碍了我们遏制结核病和疟疾等全球流行病以及简单葡萄球菌感染的能力。除非制定创新战略,生产出强有力和有效的新型抗生素,否则卫生保健费用将继续攀升,我们甚至将完全失去与最常见感染作斗争的能力。核酸是药物设计的途径,既可以作为治疗药物,也可以作为靶标。在此,我们建议建立新的方法来鉴定抗生素核糖体靶点和先导化合物。我们正在开发快速和低成本的方法来筛选序列特异性小分子的新的抗核糖体活性。我们将构建序列特异性核糖体靶向低聚物作为抗菌药物。核糖体组分之间的复合物将被用作小分子药物文库的靶标,这些药物文库可使核糖体失活,阻止细菌蛋白质合成并引起细菌感染
