Nucleic acid probe containing fluorescent tricyclic base-linked acyclonucleoside for detection of single nucleotide polymorphisms
摘要:
The development of a reliable and simple method for detecting single nucleotide polymorphisms (SNPs), common genetic variations in the human genome, is currently an important research area because SNPs are important for identifying disease-causing genes and for pharmacogenetic studies. Here, we developed a novel method for SNP detection. We designed and synthesized DNA probes containing a fluorescent tricyclic base-linked acyclonucleoside P. The type of nucleobases involved in the SNP sites in the DNA and RNA targets could be determined using four DNA probes containing P. Thus, this system would provide a novel and simple method for detecting SNPs in DNA and RNA targets. (C) 2011 Elsevier Ltd. All rights reserved.
据报道,天然存在的核苷碱基腺嘌呤的伸展型8-氨基咪唑并[4',5':5,6]吡啶[2,3- d ]嘧啶(7)的合成。它们的制备涉及嘌呤转化为5- arninoimidazo [4,5- b ]嘧啶-6-甲腈(1)通过与丙二腈反应,接着进行施工在两个步骤中的嘧啶环的通过的乙氧基亚甲基衍生物3。可以以类似方式将8-氮杂嘌呤转化为8-氨基-1,2,3-三唑并[4',5':5,6]吡啶并[2,3- d ]嘧啶8。
