Definitions
- the present invention relates to the field of chemistry, and more particularly to that of peptide chemistry. More specifically, it relates to acylated pseudodipeptides carrying a functionalized auxiliary arm, which may or may not be grafted in the form of conjugates and the auxiliary arm of which gives the molecule original properties in terms of biological activities and in physical- chemical.
- the chemical nature of the auxiliary arm gives an additional dimension to the acylated pseudodipeptide by finely modulating its original properties and giving it new ones.
- These molecules carrying a functionalized auxiliary arm can be conjugated to a phamacophore, to an antigen or to a vector molecule.
- Bioconjugation involves the coupling of two or more chemical entities to form a new molecular complex with properties different from those of its individual components. Natural or synthetic products with their own pharmacological properties can thus be combined with one another to create new entities with original or improved physico-chemical and pharmacological properties compared to the starting compounds.
- the applications of bioconjugation affect all areas of human, veterinary medicine and diagnostic methods.
- a hapten-adjuvant conjugate could prove to be very effective as a vaccination adjuvant.
- Ikeda et al. [(1999) Chem. Pharm. Bull., 47 (4), 563-568] have presented a synthesis between a structural analogue of Lipid A and a tumor antigen of peptide nature and demonstrated in vitro mitogenic activity.

- These compounds are distinguished by interesting and original pharmacological properties, in particular immunomodulatory. They are of particular interest in the preparation of vaccine compositions in formulations by admixture or as covalently conjugated with antigens of polypeptide or polysaccharide nature or on compounds consisting of polypeptides conjugated to polysaccharides. They can be used in particular in the prevention of infections of viral, microbial and protozoal origin or in the therapy of certain autoimmune diseases. They also find use as a vector of a molecule of therapeutic interest by their properties of non-covalent association according to the more or less hydrophilic or hydrophobic character of their auxiliary arm. Their chemical properties which allow them to be coupled with molecules of therapeutic interest, just as their amphiphilic character favors the formulations and the transport of the molecules which are associated to them towards the membrane receptors, as well as towards the cell walls and the cytoplasm.
- They can be used alone or in combination, covalent or not, with a molecule of therapeutic interest by extratemporary ex vivo incubation with blood cells in order to render the cells immunocompetent before re-inoculating them in vivo by the parenteral route.
- the molecules show similar properties, as adjuvants of the immune system used for example for, vaccination, in covalent association or not with the appropriate antigens, against diseases of viral, parasitic, microbial and fungal origin. These molecules, conjugated or not, can also be used in the therapy of certain autoimmune diseases.
- some of the compounds according to the invention after covalent association or not, show different properties in their capacity to induce the production of cytokines or the maturation of the immunocompetent stem cells coming from the hematopoietic and lymphoid organs.
- Some of the compounds according to the invention are capable of promoting the maturation and the differentiation of monocytes into functional dentritic cells, in the presence or in the absence of the appropriate antigen and thus contribute to strengthening humoral and cellular immunity.
- Some of the compounds promote the differentiation of cells of the hematopoietic system, in particular of the bone marrow, and make it possible to improve or correct certain dysfunctions of the immune system. They show in particular antiviral properties.
- the compounds according to the invention are particularly advantageous because of their low toxicity.

- the humoral response is presented in Figure 85 (2 weeks after the second injection) and Figure 86 (2 weeks after 3rd injection).
- the positive responses are observed in 5 out of the 7 animals in group 5 (animals having been immunized with peptide 1 conjugated by an auxiliary arm to 4 units of acylated pseudodipeptide).
- the percentage of responder mice increases with the 3rd injection since mice B and D show a titer of antibody significant but low.
- Group 3 immunized with the same peptide mixed with the same adjuvant does not produce a significant antibody titer.
- An emerging response is observed after 3 immunizations in group 7 (monoconjugate with peptide 2 supplemented by the free adjuvant OM-197).
- the tetraconjugate OM-197-peptide 2 is capable of inducing an antibody response in all mice immunized with a medium to low titer.
- the evaluation of cell activity is determined by the frequency of CTLs, secreting interferon- ⁇ , specific to the PyCS 252-260 epitope. The results are presented in Table 3.
- the positive control is represented by group 2 and the negative control represented by the adjuvants alone (group 1 and 8).
- the control of cell stimulation by Concanavalin A is positive for all the mice.
- Groups 5 (tetra-conjugate) and 7 (monoconjugate + adjuvant) show positive CTL responses.
- the aim of this experiment is to determine the highest concentration of acylated pseudodipeptide carrying a grafted auxiliary arm which does not induce fever in an injected rabbit i.v ..
- Group 1 1.0 mg / kg
- Group 2 0.1 mg / kg
- the rabbits are weighed and immobilized in boxes provided for this purpose. Temperature probes are introduced into their rectum.
- Each rabbit then receives an i.v. injection of product or control (sterile water to
- the compounds according to the invention are not pyrogenic at doses lower than 0.1 mg / kg.
