Disclosed are compounds and compositions for the activation or induction of expression of a pattern recognition receptor (e.g., STING, RIG-I, MDA5), and methods of use thereof.
The present invention provides a protected nucleotide for elongation, which can be purified efficiently and in a high yield by a liquid-liquid extraction operation, and can achieve an oligonucleotide production method by a phosphoramidite method.
It has been found that the above-mentioned problem can be solved by a particular oligonucleotide comprising a protected base and/or particular oligonucleotide protected by a branched chain-containing aromatic group at 3′-position.

The present invention relates to a chirally-modified dsRNA agent capable of inhibiting the expression of a target gene. The sense and antisense strands of chirally-modified dsRNA agent independently or in combination comprises one or more site specificsite specific/position specific, chirally-modified internucleotide linkages.
