Oligodeoxynucleotide analogs with 5′‐linked anthraquinone

Abstract
We report here the synthesis of novel 5′‐linked oligodeoxynucleotides, both normal phosphodiester and phosphorothioate analogs, in which a covalently attached group at the 5′‐terminus is an anthraquinone. These compounds represent a new class of antisense compounds in which the base sequence of the oligodeoxynucleotide serves to deliver a nuclease‐resistant reactive drug‐like molecule to a cellular target nucleic acid (mRNA or DNA).
