NOVEL PHOSPHOTRIAZOLE MRNA 5`-END CAP ANALOGS, COMPOSITION COMPRISING THE SAME, RNA MOLECULE INCORPORATING THE SAME, USES THEREOF AND METHOD OF SYNTHESIZING RNA MOLECULE, PROTEIN OR PEPTIDE

摘要

The object of the invention is a compound of formula (I), or a stereoisomer or salt thereof, wherein R1 and R2 are selected from the group consisting of N, N+-CH3, N+-C2H5, N+-C3H8, N+- C4H5, N+-CH2C6H5 wherein at least one of R1, R2 is not N. n and m are independently chosen from the group consisting of 0, 1 and 2; X is selected from the group consisting of O, NH, S, CH2 k is 1 or 2 Y is either void or selected from the group of -CH2-, -CH2CH2-, -CH2O-, -CH2S-, -CH2NH-, - CH2CH2O-, -CH2CH2NH-, -CH2CH2S- R3, R4, R5, R6 are selected from the group consisting of H, OH, OCH3, or OCH2CH3; wherein R3 and R4 may be the same or different; R5 and R6 may be the same or different; if either of R3, R4 is different than OH than R5 and R6 are both OH; if either of R5, R6 is different than OH than R3 and R4 are both OH. The object of the invention is also a composition comprising the compound of the invention, an RNA molecule incorporating the same, uses thereof and a method of synthesizing, in vitro or in vivo, the RNA molecule, as well as a method of synthesizing a protein or peptide in vitro, or in vivo or in cultured cells, said method comprising translating the RNA molecule.
