Abstract

The invention provides compounds including a CpG oligodeoxynucleotide sequence linked to a lipid by a linker and related compositions and methods. The invention features a compound consisting of the nucleotide sequence of SEQ ID NO:1, at its 5′ end, bonded or linked by a linker to a lipid. Further, the invention features a method of treating a cancer in a human patient, comprising administering to the patient the compound. Further, the invention features a pharmaceutical composition including the compound and a pharmaceutically acceptable carrier. The invention features a kit including (I) the compound or a composition comprising the compound; and (ii) a protein comprising SEQ ID NO:2 or SEQ ID NO:3.

Claims (56)

1. A compound consisting of the nucleotide sequence 5′-TCGTCGTTTTGTCGTTTTGTCGTT-3′ (SEQ ID NO:1), at its 5′ end, bonded or linked by a linker to the following lipid:

or a salt thereof,

wherein X is O or S, and wherein the nucleotides in the nucleotide sequence are optionally joined by one or more phosphorothioate bonds.

2. The compound of claim 1 , wherein the nucleotide sequence is bonded to the lipid.

3. The compound of claim 1 , wherein all internucleoside groups connecting the nucleosides in 5′-TCGTCGTTTTGTCGTTTTGTCGTT-3′ (SEQ ID NO:1) are phosphorothioates.

4. A method of treating a human papillomavirus (HPV) positive cancer in a human patient comprising administering to the patient the compound of claim 1 , a protein comprising the amino acid sequence:
