Abstract: 6-O-(2-Nitrobenzyl)guanosine and 4-O-(2-nitrobenzyl)uridine triphosphates (NBGTP, NBUTP) were synthesized, and their biochemical and photophysical properties were evaluated. We synthesized NBUTP using the canonical triphosphate synthesis method and NBGTP from 2',3'-O-TBDMS guanosine via a triphosphate synthesis method by utilizing mild acidic desilylation conditions. Deprotection of the nitrobenzyl group in NBGTP and NBUTP proceeded within 60s by UV irradiation at 365nm. Experiments using NBGTP or NBUTP in T7-RNA transcription reactions showed that NBGTP could be useful for the photocontrol of transcription by UV irradiation.
