This invention provides compounds that are of the class of nucleoside analogs, and more specifically nucleoside analogs that have a non-standard nucleobase, and more specifically analogs where a side chain is appended to said non-standard nucleobase, where said side chain can be cleaved so as to leave behind no more than five atoms appended to the nucleobase as a “scar”. The claimed compounds are useful as intermediates in processes that transiently introduce tags, labels, fluorescent molecules, or other species into oligonucleotides, as in sequencing using cyclic reversible termination, in in vitro selection using functionalized nucleotides that must later be PCR amplified, or in nucleotide capture protocols used in diagnostics.
这项发明提供了一类核苷类似物,更具体地说是具有非标准核碱基的核苷类似物,更具体地说是在所述非标准核碱基上附加侧链的类似物,其中所述侧链可以被切断,以使附加在核碱基上的原子不超过五个,形成“疤痕”。所述化合物可用作在寡核苷酸中短暂引入标记、标签、荧光分子或其他物种的过程中的中间体,例如使用循环可逆终止测序,在体外选择中使用必须后来进行PCR扩增的功能化核苷酸,或在诊断中使用的核苷酸捕获协议中。
