Definitions
- the invention relates to the use of carbohydrates for immunomodulation, for immunosuppression and for the treatment of infections in humans and animals and the food, dietetic and pharmaceutical compositions containing the carbohydrates.
- One way of influencing such ligand-receptor relationships is to block the respective receptors or ligands of one of the two cell surfaces or both cell surfaces.
- sialic acids makes an important contribution to the pathogen-cell interactions mentioned on the one hand and to cell-cell interactions on the other hand.
- These monosaccharides are particularly effective as a component of oligosaccharides and glycoconjugates such as glycolipids and Glycoproteins (Traving and Schauer, Structure function and metabolism of sialic acids, Gell. Mol. Life Sei., Vol 54 1998).
- Sialic acids occur in up to 40 different forms of derivatization and have so far been found in humans, animals and some viruses, bacteria and fungi.
- sialic acids In addition to the physicochemical effect of the negative charge of the carboxyl group, the main function of sialic acids is the specific involvement in molecular and cellular recognition processes (Keim, S. & Schauer, R. (1997) Sialic acids in molecular and cellular interactions. Int. Rev. Cytol. 175, 137-240). These include the stabilization of enzymes and other proteins, self-not-self-recognition of the immune system, masking of cells and proteins.
- the Siglecs represent a special class of sialic acid-specific lectins (P.R. Crocker et al. (1998) Siglecs - a family of sialic aeid-binding lectins. Glycobiol., 8, Glyco Forum 2 v-vi.). These molecules have immunoglobulin-like domains, are lectin-like receptors and bind sialic acid as an essential feature.
- the structure of the ligands or receptors is generally essential for their mechanism of action.
- the binding of a ligand to a receptor is the first event that can trigger further signal cascades.
- Siglecs was also shown to be involved in signal transduction mechanisms. So z. B. in Siglec-2 (CD22) occurring tyrosines are phosphorilized, which in turn leads to a reduced activation of B cells via further intermediate steps.
- the mechanism of binding specific proteins to carbohydrate structures is also important for the attachment of bacteria to epithelial surfaces. Since attachment is the first step in an initial infection, inhibiting this binding is an important goal of infection prevention.
- the bacterial lectins (adhesins) that specifically recognize ⁇ 2-3 are subject to the same mechanism that applies to the Siglecs.
- the so-called clustering of both receptor and ligands plays an important role in the binding intensity.
- An important criterion is the polyvalence of the binding-active ligands. The more ligand structures are combined in one molecule, the stronger the interactions between ligand and receptor or between two or more cells can be. This applies in particular to interactions in which the cross-linking of molecules or cells modulates the function of a biological process. It should be emphasized that polyvalent ligands lead to a cross-linking of the receptors and thus can produce a different signal effect.
- the object of the present invention is to show a way in which immunomodulation, immunosuppression and treatment of infections in humans and animals can be achieved with the aid of carbohydrates.
- Sia is a sialic acid or a sialic acid derivative in an ⁇ 2-3 bond
- Gal is a galactose-monosaccharide unit
- HexNac is an N-acetylated galactosamine or glucosamine monosaccharide unit (GalNAc or GIcNAc) means hex is a galactose or glucose monosaccharide unit (Gal or Glc)
- C is HexNac or Hex or is absent
- n stands for 1 to 50
- V stands for OH, a carbohydrate residue or for a connection point to a carrier T, with the proviso that if V stands for OH, n stands for 1 and, if V stands for a carbohydrate residue or for a carrier T, n is the number of this carbohydrate residue or
- Carrier means directly bound carbohydrate units of the general formula II
- X represents a sialic acid or a sialic acid derivative thereof, it being possible for a sialic acid or the sialic acid derivative to have a second sialic acid or a sialic acid derivative or more or more sialic acids or sialic acid derivatives bonded in an ⁇ 2-8 bond, a phosphate, sulfate or carboxyl group or one Monosaccharide with a phosphate, sulfate or carboxyl group means and only one of the radicals X is present, used for immunomodulation, for immunosuppression and for the prevention and treatment of infections in humans and animals.
- the carbohydrates according to the invention must have at least one carbohydrate unit of the general formula II [Sia ⁇ 2-3-Gal-HexNac (X) -Hex (X) -C -] -; the radicals Sia, Gal, HexNac, Hex, X and C have the meanings given in connection with the general formula I.
- This carbohydrate unit of the general formula II thus represents a constituent of the carbohydrates of the general formula I according to the invention. If the radical V in the formula of the general formula I is OH, then the carbohydrates of the general formula I are composed of a carbohydrate unit of the general formula II and this Rest V built up.
- the preferred linkages for the sialised carbohydrates are as follows: ⁇ 1 -2, ⁇ 1-3, ⁇ 1 -4, ⁇ 1 -6, ⁇ 2-3, ⁇ 2-6, ⁇ 2-8, ß1 -2, ß 1 -3 ß 1 -4 and ß 1 -6. Both one and more of the bonds mentioned can occur in a carbohydrate or glycan.
- Preferred are ⁇ -linked basic structures (I, II) with ⁇ -glycosidically charged groups, provided that X also represents a glycan.
- the residue V can also stand for a carbohydrate residue or for a connection point to a carrier T. In the latter case, V strictly speaking does not mean a remainder, but rather this connection point.
- the carbohydrate unit of the general formula II is bound or immobilized on a carrier via this connection point V.
- the type of carrier is not particularly critical so that a variety of carriers can be used. Up to 50 carbohydrate units of the general formula II can be bound to such a carrier, each of which is bound or coupled to this carrier T via the connection point V.
- the index n used in the context of the present documents thus denotes the number of carbohydrate units of the general formula II and not a chain of n elements of these carbohydrate units.
- n stands for 1-50, then this means that n stands for an integer 1-50 and thus for 1, 2, 3, 4, 5, 6, 7, 8,
- the carrier T is in particular a peptide, a protein, a polymer or a biopolymer, the linkage with the peptide or protein being in particular N- or O-glycosidic.
- Polyhydroxybutyric acid can be used as a biopolymer.
- a suitable polymer is, for example, polyacrylamide.
- the residue V can also represent a carbohydrate residue. This is preferably a monosaccharide, oligosaccharide or polysaccharide residue. Examples include: milk oligosaccharides, storage carbohydrates (especially starch) and skeletal carbohydrates such as pectins, celluloses and galactomannans. These carbohydrates can also be referred to as biopolymers. For clearer terminological delimitation, however, the above-mentioned biopolymers are not included for the purposes of the present invention.
- the carbohydrate residue representing residue V can also be one or more (also chain-like) carbohydrate residues which are composed in the same way as the carbohydrate units of the general formula II, the linkages of these carbohydrate residues being different.
- the carbohydrate unit of the general formula II has at least two negative charges which are present on a core of at least 3 and in particular 4 neutral monosaccharides (Gal, HexNac, Hex and C).
- One of these negative charges is located at the non-reducing end of the core (can also be referred to as core) as ⁇ 2-3-bound sialic acid on a galactose.
- the second charge is either sub-terminal as sialic acid, but can also be replaced by other charged groups, namely phosphate, sulfate and carboxyl groups.
- These phosphate, sulfate and carboxyl groups can are located directly on the monosaccharides HexNac and Hex or are bound to another monosaccharide. In other words, this other monosaccharide then represents the bridge between this charged group and the monosaccharide HexNac or Hex of the carbohydrate unit of the general formula II.
- radical V is a carbohydrate radical whose composition corresponds to the carbohydrate unit of the general formula II, preference is given to using those radicals V in which there are two negative charges per 3 or 4 neutral monosaccharides.
- radicals X Only one of the radicals X is present in the carbohydrate units of the general formula II.
- either the monosaccharide HexNac or the monosaccharide Hex carries a radical X of the type described above.
- monosaccharide unit would have to be used strictly, because these monosaccharides are not unique, but are to other monosaccharides or groups bound. For the sake of simplicity, however, only the expression monosaccharide or the specific name of the monosaccharide (e.g. galactose, glucose, hexosamine etc.) is used.
- the monosaccharide unit labeled Sia is preferably acetylneuraminic acid (NeuAc) or N-glycolylneuraminic acid (NeuGc).
- the O-acyl derivative of the sialic acid of the radicals Sia and X is, for example, an O-acetyl derivative.
- radical X is a sialic acid or an O-acyl derivative
- it is preferably NeuAc, NeuGc and their derivatives, e.g. B. O-acetylated sialic acid in ⁇ 2-3 or ⁇ -2-6 bond.
- a second sialic acid or a plurality of sialic acids in an ⁇ 2-8 bond can be present on the radical X.
- the second or third Neu ⁇ Ac is only necessary because of the charge, to achieve an increase in affinity.
- the type of binding does not matter.
- This second Neu ⁇ Ac (radical X) can also be replaced by another group carrying a negative charge (phosphate, sulfate, carboxyl, also in the form of carboxylate).
- the carbohydrate units of the general formula II are therefore of primary importance for immunomodulation, immunosuppression and for the treatment of infections in humans and animals with the aid of the carbohydrates according to the invention.
- the type of carrier T to which these carbohydrate units of the general formula II can be bound is therefore also of a subordinate nature.
- the carrier T can therefore be of any type. It is preferably a carbohydrate, a peptide, a protein, a polymer or a biopolymer, the linkage with the peptide or protein preferably being N- or O-glycosidic.
- the carrier T is furthermore preferably lipophilic compounds which have one or more carbohydrate units or carbohydrate units of the general formula II which represent or represent the head group or head groups thereof. Preferred lipophilic compounds are glycolipids and gangliosides.
- Disialyl-lacto-N-tetraose DS-LNT
- disialyl-lacto-N-neo-tetraose D-LNnT
- glycomacropeptide GMP
- the GMP preferably comes from animal milk, for example sheep, goat, buffalo, camel and especially cow's milk.
