CpG oligonucleotide analogs containing hydrophobic T analogs with enhanced immunostimulatory activity
View Patent ↗The invention relates to oligonucleotides including at least one lipophilic substituted nucleotide analog and a pyrimidine-purine dinucleotide. The invention also relates to pharmaceutical compositions and methods of use thereof.
1. An oligonucleotide comprising the sequence JU*C-G*A*C*G*T*C*G*A*T*C*G*G*C*G*C*G*C*G*C*C*G*T (SEQ ID No. 60), wherein the JU is 5′-Iodo-2′-deoxyuridine, the * is phosphorothioate internucleotide linkage, and the - is phosphodiester internucleotide linkage.
2. An oligonucleotide comprising the sequence JU*C*G*A*C*G*T*C*G*A*T*C*G*G*C*G*C*G*C*G*C*C*G*T (SEQ ID No. 61), wherein the JU is 5′-Iodo-2′-deoxyuridine and the * is phosphorothioate internucleotide linkage.
3. An oligonucleotide comprising the sequence JU*C-G*T*C*G*A*C*G*A*T*C*G*G*C*G*G*C*C*G*C*C*G*T (SEQ ID No. 66), wherein the JU is 5′-Iodo-2′-deoxyuridine, the * is phosphorothioate internucleotide linkage, and the - is phosphodiester internucleotide linkage.
4. An oligonucleotide comprising the sequence JU*C*G*T*C*G*A*C*G*A*T*C*G*G*C*G*G*C*C*G*C*C*G*T (SEQ ID No. 67), wherein the JU is 5′-Iodo-2′-deoxyuridine and the * is phosphorothioate internucleotide linkage.
5. A pharmaceutical composition comprising the oligonucleotide of any one of claims 1 to 4 , said composition further comprising an antigen.
6. A pharmaceutical composition comprising the oligonucleotide of any one of claims 1 to 4 , said composition further comprising a pharmaceutically acceptable carrier.
7. A pharmaceutical composition comprising the oligonucleotide of any one of claims 1 to 4 , said composition further comprising an antigen and a pharmaceutically acceptable carrier.
