Assessment of new 2'-O-acetalester protecting groups for regular RNA synthesis and original 2'-modified proRNA.

Abstract:

:New base-labile acyloxymethyl groups were evaluated to protect 2'-OH functions of ribonucleotides for regular RNA synthesis in order to shorten the deprotection procedure upon ammonia. These same acetalester groups were assessed in 2'-modified proRNA as biolabile 2'-protections removable by cell enzymes to generate parent RNA. Demasking of 2'-modified pro-uridylates was studied in cell extracts.
