  苄基碳取代的立体化学与 2-硝基苄基的环修饰作为快速裂解可逆终止子的关键决定因素

  摘要：

  已经开发出一套完整的 2-硝基苄基修饰的可逆终止剂，它们在暴露于紫外线下时会产生天然的羟甲基核苷酸（见方案）。苄基碳上的立体特异性 ( S )-叔丁基 (R) 和 2-硝基苄基环上的 5-OMe 基团 (R') 的组合显着提高了光化学裂解的速率。对于 7-deaza-7-hydroxymethyl-2'-deoxyguanosine，这些修饰导致速率增加超过一个数量级。

  The present invention relates generally to 3'-OH unblocked nucleotides and nucleosides labeled and unlabeled with 5-methoxy-substituted nitrobenzyl-based photocleavable terminating groups for use in methods and systems related to DNA and RNA sequencing and analysis. These compounds may be used as reversible terminators as they exhibit fast nucleotide incorporation kinetics, single-base termination, high nucleotide selectivity, and rapid terminating group cleavage that results in a naturally occurring nucleotide.

  本发明通常涉及用于DNA和RNA测序和分析方法及系统中的3'-OH未阻断核苷酸和核苷的标记和未标记的5-甲氧基取代硝基苯基光致裂解终止基团。这些化合物可用作可逆终止剂，因为它们表现出快速的核苷酸结合动力学、单碱基终止、高核苷酸选择性和快速的终止基团裂解，导致自然发生的核苷酸。

  Provided are novel nucleotides, nucleoside, and their derivatives described herein, that can be used in DNA sequencing technology and other types of DNA analysis. In one embodiment, the nucleotide or nucleoside with an unprotected 3′-OH group is derivatized at the nucleobase to include a fluorescent dye attached via a linker to a photocleavable terminating group. The photocleavable-fluorescent group is designed to terminate DNA synthesis as well as be cleaved so that DNA oligomers can be sequenced efficiently in a parallel format. The design of such rapidly cleavable fluorescent groups on nucleotides and nucleosides can enhance the speed and accuracy of sequencing of large oligomers of DNA in parallel, to allow rapid whole genome sequencing, and the identification of polymorphisms and other valuable genetic information, as well as allowing further manipulation and analysis of nucleic acid molecules in their native state following cleavage of the fluorescent group.

  本文介绍了一些新型的核苷酸、核苷和它们的衍生物，可以用于DNA测序技术和其他类型的DNA分析。在一个实施例中，带有未保护的3'-OH基团的核苷酸或核苷在核碱基处衍生化，包括通过连接剂连接的荧光染料和光解终止基团。光解荧光基团旨在终止DNA合成，同时被裂解，以便在并行格式中高效地测序DNA寡聚物。在核苷酸和核苷上设计这种快速可裂解的荧光基团可以增强大型DNA寡聚物并行测序的速度和准确性，以实现快速的全基因组测序，并识别多态性和其他有价值的遗传信息，同时在裂解荧光基团后允许进一步操作和分析核酸分子的自然状态。
