The present invention relates to new adjuvants and the uses in pharmaceutical compositions, like in vaccines. In particular, the present invention provides new compounds useful as adjuvants and/or immunomodulators for prophylactic and/or therapeutic vaccination in the treatment of infectious diseases, inflammatory diseases, autoimmune diseases, tumors, allergies as well as for the control of fertility in human or animal populations. The compounds are particularly useful not only as systemic, but preferably as mucosal adjuvants. In addition, the invention relates to its uses as active ingredients in pharmaceutical compositions.

Cycic di-GMP, or a cyclic dinucleotide analogue thereof that has the same effect as cyclic di-GMP, stimulates or enhances immune or inflammatory response in a patient or enhances the immune response to a vaccine by serving as an adjuvant. Cyclic di-GMP, or a cyclic dinucleotide analogue thereof, also has neuroprotective properties for use as a neuroprotective agent to inhibit, treat, or ameliorate the effects of injuries, diseases,

A cyclic dinucleotide compound of Formula (I):

wherein X₁ is H or F; X₂ is H or F; at least one among X₁ and X₂ is a fluorine atom; Z is OH, OR₁, SH or SR₁, wherein: R₁ is Na or NH₄, or R₁ is an enzyme-labile group which provides OH or SH in vivo such as pivaloyloxymethyl; B₁ and B₂ are bases chosen from Adenine, Hypoxanthine or Guanine, and B₁ is a different base than B₂ and a pharmaceutically acceptable salt thereof. Pharmaceutical compositions including the cyclic dinucleotide, as well as their use in the treatment of a bacterial infection, a viral infection or a cancer are also described.

The present invention relates to the use of the cyclic dinucleotide c-di-GMP and cyclic dinucleotide analogues thereof in a method for attenuating virulence of a microbial pathogen or for inhibiting or reducing colonization by a microbial pathogen. This method further inhibits microbial biofilm formation and is capable of treating bacterial infections. The microbial colonization or biofilm formation inhibited or reduced may be on the skin or on nasal or mucosal surface. The microbial colonization or biofilm formation inhibited can also be on the surfaces of medical devices, especially those in close contact with the patient, as well on the surfaces of industrial and construction material where microbial colonization and biofilm formation is of concern.

The present invention relates to methods for preparing virus-like particles comprising immunogenic cyclic dinucleotides.

An intraorally administrable vaccine composition useful to be a preventive or therapeutic agent for infectious diseases, and effectively induces a systemic immune response or a mucosal immune response is provided. A vaccine composition for administration to the oral cavity of a human or an animal, the vaccine composition containing at least one antigen derived from an infectious disease, and at least one selected from the group consisting of a toll-like receptor 4 (TLR4) agonist, a toll-like receptor 2/6 (TLR2/6) agonist, and cyclic dinucleotide, or a derivative or salt thereof.

Cyclic di-GMP or cyclic dinucleotides thereof can be used to inhibit cancer cell proliferation or to increase cancer cell apoptosis in vitro as well as in vivo in a patient.

Disclosed is the use of fluorinated cyclic dinucleotides and pharmaceutically acceptable salts thereof as an adjuvant for the preparation of an oral vaccine. Further disclosed is the use of fluorinated cyclic dinucleotides and pharmaceutically acceptable salts thereof for enhancing the immune response to an orally administered vaccine.

The present disclosure relates to 2′3′ cyclic phosphonate dinucleotides of general formula (J), their pharmaceutically acceptable salts, their pharmaceutical composition and combinations of said substances and other medicaments or pharmaceuticals. The disclosure also relates to the use of said compounds for the treatment or prevention of diseases or conditions modifiable by STING protein modulation, such as cancer or viral, allergic and inflammatory diseases. In addition, these substances can be used as adjuvants in vaccines.

The present invention provides a vaccine composition which comprises a cellular immunity induction promoter universally usable against various antigens in cellular immunity induction by mucosal administration of the antigen and exerts a high cellular immunity inducing effect by mucosal administration. The present invention provides a vaccine composition for mucosal administration to induce cellular immunity, comprising: (i) an antigen; and (ii) one or more cellular immunity induction promoters selected from the group consisting of a TLR ligand, a cyclic dinucleotide, a helper peptide and an immunomodulatory small molecule drug.

A kit of parts includes a) gemcitabine or a pharmaceutically acceptable salt thereof and b) a cyclic dinucleotide or pharmaceutically acceptable salt thereof, wherein the cyclic dinucleotide or pharmaceutically acceptable salt thereof is an agonist of the receptor known as “stimulator of interferon genes” (STING), for use in the treatment of solid pancreatic cancer.

Provided herein are the 3′3′ cyclic phosphonate dinucleotides of general formula J, their pharmaceutically acceptable salts, a pharmaceutical composition containing them and combinations of said substances and other medicaments or pharmaceuticals. The disclosure also relates to the use of said compounds for the treatment or prevention of diseases or conditions modifiable by STING protein modulation, such as cancer or viral, allergic and inflammatory diseases. In addition, these substances can be used as adjuvants in vaccines.

The invention discloses cyclic dinucleotide analogues, a pharmaceutical composition of the analogues and applications of the analogues and the pharmaceutical composition. The cyclic dinucleotide analogs (I), an isomer, prodrug, stable isotope derivative or pharmaceutically acceptable salt of the analogs have a structure shown in the specification. The cyclic dinucleotide analogs provided by the invention can be used as regulators of stimulator of interferon genes (STIG) and related signaling pathways, and can effectively treat and/or alleviate multiple types of diseases, including but not limited to malignant tumors, inflammation, autoimmune diseases and infectious diseases; and in addition, the STING regulators can also be used as vaccine adjuvants.
