Synthesis and Multiple Incorporations of 2′-O-Methyl-5-hydroxymethylcytidine, 5-Hydroxymethylcytidine and 5-Formylcytidine Monomers into RNA Oligonucleotides.
- Abstract:
- The synthesis of 2'-O-methyl-5-hydroxymethylcytidine (hm5 Cm), 5-hydroxymethylcytidine (hm5 C) and 5-formylcytidine (f5 C) phosphoramidite monomers has been developed. Optimisation of mild post-synthetic deprotection conditions enabled the synthesis of RNA containing all four naturally occurring cytosine modifications (hm5 Cm, hm5 C, f5 C plus 5-methylcytosine). Given the considerable interest in RNA modifications and epitranscriptomics, the availability of synthetic monomers and RNAs containing these modifications will be valuable for elucidating their biological function(s).
