  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。

  The disclosure relates to nucleic acids that contain modifications at the 5'-end, 3'-end or 5'-end and 3'-ends, and compounds that can be used to make the modified nucleic acids are disclosed. The modified nucleic acids have improved expression, lower immunogenicity and improved stability compared to unmodified nucleic acids.

  该披露涉及在5'-末端、3'-末端或5'-末端和3'-末端上含有修饰的核酸，以及可用于制备修饰核酸的化合物。与未经修饰的核酸相比，修饰核酸具有更好的表达、更低的免疫原性和更好的稳定性。

  Linker compounds, methods of making them, and methods of using them as linking agents for oligonucleotides and other chemical and biological substances are described. Embodiments of linker compounds are configured or selected to exhibit higher stability to cleavage by serum nucleases relative to intracellular nucleases, enabling enhanced control of longevity and hence bioavailability to a target cell of the chemical and biological substances linked together by such linker compounds when administered to a subject.

  本文描述了连接剂化合物、制备方法以及将它们用作寡核苷酸和其他化学和生物物质的连接剂的使用方法。连接剂化合物的实施例被配置或选择以相对于细胞内核酸酶具有更高的稳定性，从而使得通过这种连接剂化合物连接在一起并在给予受试者时可控制生物和化学物质的寿命和因此生物可用性增强到目标细胞。
