DEVELOPMENT OF A PROBE CONTAINING NOVEL FLUORESCENT TRICYCLIC-NUCLEOSIDE ANALOGS FOR DETECTING SINGLE NUCLEOTIDE POLYMORPHISMS

摘要

Here we report the synthesis of nucleoside analogs containing several aryl groups at the 6-position of the fluorescent tricyclic base, 8-amino-3-(2,3-dihydroxypropyl)imidazo[4',5':5,6]pyrido[2,3-d]pyrimidine (1), to expand the fluorescence color range of single nucleotide polymorphism (SNP)-detecting probes. The identity of the RNA target bases could be determined using probes containing an analog with a phenyl group at the 6-position of 1.
