Novel and efficient syntheses create novel piperazinone intermediates which facilitate the production and use of PNAs. Such syntheses and the products enhance the feasibility of a system which permits the rapid identification of PNA oligomers useful as therapeutics, diagnostics and/or gene characterization tools. A first component of the system is a universal PNA library that most preferably incorporates one or more universal nucleotide bases into carefully selected positions within each oligomer species thereby providing the library with the screening ability of a much larger library. The second component of the system is a high throughput screening system that includes a number of assays designed to provide information on the binding activities of the different PNAs to a target nucleotide sequence (generally, a DNA or RNA sequence). The third component is a software system especially designed to provide rapid analysis of the data collected from the high throughput screening system and to determine therefrom the sequence base identities and sequence lengths of PNA oligomers most likely to bind to and appropriately affect the target molecule.
新颖高效的合成方法创造了新颖的哌嗪酮中间体,有助于PNAs的生产和使用。这种合成方法和产品增强了一个系统的可行性,该系统允许快速识别可用作治疗、诊断和/或基因表征工具的PNA寡聚体。该系统的第一个组成部分是一个通用的PNA库,最好将一个或多个通用核苷酸碱基精心选定地嵌入到每个寡聚体物种的特定位置,从而赋予该库类似于更大库的筛选能力。该系统的第二个组成部分是一个高通量筛选系统,包括多种设计的检测方法,用于提供关于不同PNAs与目标核苷酸序列(通常为DNA或RNA序列)结合活性的信息。第三个组成部分是一个专门设计的软件系统,用于快速分析从高通量筛选系统收集的数据,并据此确定最可能与目标分子结合并适当影响目标分子的PNA寡聚体的序列碱基身份和序列长度。
