  Efficient Preparation of Organic Substrate−RNA Conjugates via in Vitro Transcription

  摘要：

  A concise synthetic way has been developed for the preparation of guanosine monophosphate derivatives carrying a decaethylene glycol spacer at their 5'-oxygen to which are attached a range of organic substrates. The four different compounds, prepared via a convergent synthetic strategy, carry a tethered benzylallyl ether residue (1a), an anthracene (1b), a benzyl carbamate residue (1c), or a primary amino group (1d), respectively. All four compounds have been successfully incorporated at the T-end of a 25-mer long RNA transcript via T7 RNA polymerase, and no inhibition of chain elongation could be observed. Under proper conditions, 1a and 1b can be incorporated up to 90-95% and 1c up to 68%. The amino-terminated initiator Id is incorporated less efficiently although still up to 49%. These results show that the more hydrophobic the guanosine monophosphate derivative is, the higher is its enzymatic incorporation.
