DNA Conjugated Phenoxyaniline Intercalators: Synthesis of Diethanolaminoacetamide-type Linkers.
摘要:
Two non-nucleosidic monomers conjugated to a phenoxyaniline intercalator have been synthesized and inserted into ODNs. The conjugated monomers were prepared from 2-chloro-N-(4-phenoxyphenyl) acetamide (1) either by reaction with diethanolamine and 4,4'-dimethoxytritylation, or by reaction with ethanolamine by subsequent peptide coupling type reaction with 4,4'-dimethoxytrityl protected glycolic acid. The modified ODNs moderately stabilize DNA three-way junctions when the intercalator was introduced at the branch point. For targeting RNA the results were more ambiguous.
