Modified 2′-deoxynucleosides and nucleoside triphosphates (dNTPs) bearing anthraquinone (AQ) via acetylene or propargylcarbamoyl linkers were prepared by single-step Sonogashira cross-coupling reactions halogenated nucleosides (7-iodo-7-deaza-2′-deoxyadenosine and 5-iodo-2′-deoxycytidine) or dNTPs with N-(2-propynyl)-anthraquinone carboxamide and 2-ethynylantraquinone. Polymerase incorporation of the AQ-labelled dNTPs into DNA has also been studied. Square-wave voltammetry of the AQ-labelled nucleosides and nucleotides showed one reversible peak at –0.5 V.
