  Synthesis and Properties of Combinatorial Libraries of Phosphoramidates

  摘要：

  We have assembled a set of combinatorial libraries of phosphoramidates for pharmacological evaluation. A range of functionalized and unfunctionalized diols, representing a variety of diversity elements, were converted into their corresponding dimethoxytrityl H-phosphonate derivatives which were coupled to each other to produce H-phosphonate dimers and trimers. The H-phosphonate diesters were converted into phosphoramidates by reaction with a wide range of primary and secondary amines. Very large libraries (theoretically, in excess of one million compounds) possessing five sites of diversity were generated for use in our drug discovery program. Smaller libraries with lower molecular weights were also prepared in which only two monomeric units were coupled together and converted into their phosphoramidate derivatives. Methods for the attachment of both radioactive and nonradioactive labels, including (32)phosphorus, tritium, and fluorescein, have been developed. Representative single sequences were also prepared and their chemical properties studied.

  Solid-phase synthesis of peptidomimetic oligomers with a phosphodiester backbone

  摘要：

  An unnatural biopolymer is described in which amino acid side-chains are presented along a negatively charged phosphodiester backbone. For this purpose, a series of phosphoramidite monomers was prepared from chiral 1,2-diols. These were efficiently converted into oligomers using standard coupling conditions on an automated DNA synthesizer. (C) 1998 Elsevier Science Ltd. All rights reserved.

  interior of a 12-mer oligonucleotide duplex in various sequential arrangements and investigated with CD spectroscopy and UV melting curve analysis. The CD spectra of the modified duplexes indicated B-form DNA topology. Melting curve analyses revealed trends in DNA duplex stability that correlate with the known association of DAN and NDI moieties in aqueous solution as well as the known favorable interactions

  两种新型 DNA 碱基替代亚磷酰胺1和2分别基于相对富电子的 1,5-二烷氧基萘 (DAN) 和相对缺电子的 1,4,5,8-萘四甲二亚胺 (NDI)，分别被设计、合成并整合到 DNA 寡核苷酸链中。DAN 和 NDI 人工 DNA 碱基以各种顺序排列插入 12 聚体寡核苷酸双链体内部的三碱基对区域内，并用 CD 光谱和 UV 熔解曲线分析进行研究。修饰双链体的 CD 谱表明 B 型 DNA 拓扑结构。熔解曲线分析揭示了 DNA 双链体稳定性的趋势，这与水溶液中 DAN 和 NDI 部分的已知关联以及 NDI 和天然 DNA 碱基对之间已知的有利相互作用相关。这表明 DAN 和 NDI 之间的静电互补性可以驱动 DNA 双链体的稳定性和特异性。在最有利的情况下，发现 DNA 双链体中间的 NDI-DAN-NDI 排列大约与三个 A-T 碱基对一样稳定。
