Oligonucleotide compositions and methods thereof
Among other things, the present disclosure relates to chirally controlled oligonucleotides of select designs, chirally controlled oligonucleotide compositions, and methods of making and using the same. In some embodiments, a provided chirally controlled oligonucleotide composition provides different cleavage patterns of a nucleic acid polymer than a reference oligonucleotide composition. In some embodiments, a provided chirally controlled oligonucleotide composition provides single site cleavage within a complementary sequence of a nucleic acid polymer. In some embodiments, a chirally controlled oligonucleotide composition has any sequence of bases, and/or pattern or base modifications, sugar modifications, backbone modifications and/or stereochemistry, or combination of these elements, described herein.
1. An oligonucleotide having the structure of:
mG*SmGmCmAmC*SA*SA*SG*SG*SG*SC*SA*SC*RA*SG*SmAmCmUmU*SmC (SEQ ID NO: 360), or a pharmaceutically acceptable salt thereof, wherein:
*S represents a Sp phosphorothioate;
*R represents a Rp phosphorothioate; and
m represents a 2′-OMe modification to a nucleoside.
2. The oligonucleotide of claim 1 , wherein the oligonucleotide is in a salt form.
3. An oligonucleotide, wherein the oligonucleotide is a sodium salt of:
mG*SmGmCmAmC*SA*SA*SG*SG*SG*SC*SA*SC*RA*SG*SmAmCmUmU*SmC (SEQ ID NO: 360), wherein:
*S represents a Sp phosphorothioate;
*R represents a Rp phosphorothioate; and
m represents a 2′-OMe modification to a nucleoside.
4. A chirally controlled composition of an oligonucleotide having the structure of:

mG*SmGmCmAmC*SA*SA*SG*SG*SG*SC*SA*SC*RA*SG*SmAmCmUmU*SmC (SEQ ID NO: 360), or a pharmaceutically acceptable salt thereof, wherein:
*S represents a Sp phosphorothioate;
*R represents a Rp phosphorothioate; and
m represents a 2′-OMe modification to a nucleoside.
8. The composition of claim 7 , wherein the oligonucleotide is in a salt form.
