Two novel photolabile nucleotide triphosphate (NTP) analogues were synthesized through Sonogashira coupling and their enzymatic incorporation into DNA was evaluated with three different DNA polymerases (Taq, Vent exo- and T4) by polymerase chain reaction. Both nucleotide triphosphate analogues were recognized by these DNA polymerases as substrates for primer extension. Light irradiation of PCR products removed the photolabile group and released the amino and carboxyl moieties. Further site-specific dual-labeling for oligodeoxynucleotides (ODNs) and random labeling for a long DNA construct with fluorophores were successfully achieved with incorporation of the photolabile amine modified deoxyuridine triphosphate (dUnTP).
