Abstract
Design, synthesis and T7 RNA polymerase substrate evaluation of (E)-5-[(3-selenophene-2-carboxamido)prop-1-en-1-yl]-uridine-5′-O-triphosphate is reported. The title compound is shown to be a good substrate for RNA polymerase by RNA labeling through in vitro transcription. pTRI-plasmid DNA with β-actin gene sequence (∼300 base pairs) with T7 promoter was used as a template for the in vitro transcription. Transcribed product is characterized for incorporation by gel assay and for integrity, full length and size by bioanalyzer. The title compound will be very useful in biophysical techniques to obtain information on dynamics and recognition properties in real time as well as 3D structure of nucleic acids.
