Definitions
- the invention relates to a ganglioside mixture, the use of this ganglioside mixture for the production of a dietetic, pharmaceutical and nutritional agent and a corresponding agent.
- Gangliosides are complex glycolipids that are predominantly located on the outer surface of the plasma membrane of a cell. They contain a polar part (head) composed of sugars and sugar derivatives and possibly N-acetylneuraminic acid as well as several non-polar aliphatic chains composed of fatty acids and their derivatives.
- the structure of the ganglioside oligosaccharide chain directly determines the cell-cell interaction (cell adhesions), receptor coverage (e.g. IL-2, selectins), compare Robb, RJ, J. Immunol. 1986, 136,971-976, enterotoxin binding (antibacterial / antiviral and prebiotic Effects), see also Rueda, R., Sabetel, JL, Maldonaldo, J., Molinos-Font, JA, Gil, AJ Pediatr.
- the fatty acid composition is responsible for the spatial arrangement of the molecules in a membrane (microdomain formation / clustering) and is a determining factor for the substrate-specific conversion of the glycolipids in the metabolism (enzyme-substrate specificity).
- a distinction is often not made between the two non-polar aliphatic chains, both of which are called fatty acids.
- These fatty acids are a structure and function-determining element, compare Ladisch, S., Hasegawa, A :, Li, R., Kiso, M. Biochemistry 1999, 34, 1197-1202.
- the N-acylsphingosin portion of gangliosides (ceramide) is important as an intracellular signal-mediating molecule.
- the long-chain acyl groups of gangliosides are omnipresent fatty acids in biological systems and give these gangliosides a high level of bioactivity in their diverse functions.
- Gangliosides are enzymatically (lysosomal enzymes) intracellularly converted to ceramide, this to sphingomyelin and further to sphingosine, sphingosine-1P. Ceramide also influences the synthesis of diacylglycerol and phosphoryldiacylglycerol via the sphingomyelin conversion. These substances are all highly potent signal-mediating molecules. Gangliosides and gangliosides converted to ceramide thus determine the metabolism and cell functions in a variety of ways. While the 3-keto bound fatty acid of ganglioside contains all metabolites of ceramide e.g. Sphingosine structurally and functionally determined i.e.
- N-acylated (amide) fatty acid is only contained as a fatty acid composition of the ceramide itself and corresponding glycosyl derivatives and is split off in the metabolism of the secondary messenger substances.
- acylation of the molecule determines the potency of gangliosides / ceramides and their metabolites as signal-mediating molecules.
- the metabolism of ganglioside derivatives by substrate-specific enzymes sphingomyelinase, ceramidase, sphingosine acyltransferase
- ceramide dehydrogenase ceramide dehydrogenase
- Ceramidkinase is determined by the acyl pattern as a structural element. Saturated fatty acids also cause a Carbon length up to C 24 a fast ganglioside metabolism (de novo synthesis / conversion). The specific acylation of the molecule is also relevant for the influence of gangliosides on various intracellular, regulatory enzymes (phosphokinase C, phospholipase D and various protein phosphatases / kinases).
- Anticarcinogenic effects (induces apoptosis, stops cell growth), compare Vesper, HL, Schmelz, E.-M., Nikolova-Karakashian, M.N., Dillehay, D.L., Lynch, D.V., Merril, A.H.Jr. J. Nutr. 1999, 129, 1239-1250; Farooqui, A., Harrocks, L.A., Farooqui, T., Chemistry and Physics 2000, 106, 1-29.
- T cell differentiation is induced (induction of cell maturation); Inhibition of the T cell response, see also Yanagihava, K., Kato, E :, Hitomi, S., Sunamoto, J., Wada, H. Glycoconjugate J. 1999, 16, 59-65.
- gangliosides which have been extensively described in the literature, are mainly associated with the composition of the oligosaccharide chain.
- the Lip ⁇ d portion is considered less functional, although it is known that the bioactivity of the gangliosides is caused by the
- Fatty acid composition is determined. Most of the existing patents are therefore mainly concerned with the oligosaccharide chain or do not specify any specification of the fatty acids, see JP 92105616. Others only provide information on the ratio of saturated to unsaturated fatty acids, see JP 3101691.
- US Pat. No. 5,366,963 22/94 describes the relationship between the proportion of fatty acids and a chain length ⁇ C18 and> C20 and the immunosuppressive effect of a ganglioside mixture.
- the fatty acids C18 and C20 are expressly excluded.
- the object of the present invention is therefore to provide a ganglioside mixture with an improved biological activity.
- the gangliosides correspond to the following general formula I:
- This general formula I describes those gangliosides which form the basis for the mixture according to the invention. It is not a matter of providing gangliosides of this type as such, since the mixture according to the invention can even consist of known gangliosides. Rather, the invention consists in that of the gangliosides, which fall under the formula given above and the radicals in this general formula defined in the context of the present documents, the group -CO-R1 is made up of certain fatty acids in certain amounts.
- the general formula I thus defines the mathematical and material reference base on which the material and obtain quantitative information. It is possible, for example, to obtain mixtures according to the invention exclusively by newly mixing gangliosides or ganglioside mixtures which are already known. Of course, modifications etc. of the gangliosides can also be made, which will be discussed in more detail below.
- the radical R 2 here denotes a straight, saturated alkyl radical or a straight alkenyl radical, where both radicals have 10 or more carbon atoms, for example up to 30 carbon atoms.
- the radical R 2 can thus have 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29 and 30 carbon atoms exhibit.
- the number of carbon atoms is preferably an even number, for example 14, 16 and 18.
- the alkenyl radical can have one, two or three double bonds.
- the radical R 1 denotes a straight, saturated alkyl radical with 10 or more carbon atoms, for example up to 30 carbon atoms.
- the radical R 1 can thus have 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29 and 30 carbon atoms exhibit.
- the number of carbon atoms is preferably an even number, for example 18, 20, 22 and 24.
- the radical R 1 together with the keto group bonded to it represents a fatty acid which is bonded to the rest of the molecule in the form of an amide.
- This radical -CO-R 1 is referred to as acyl fatty acids in the context of the present documents.
- an essential aspect of the present invention is that in the ganglioside mixture according to the invention the C20: 0 fatty acid makes up at least 10% by weight of the acyl fatty acids (and thus the group -CO-R 1 ; see above).
- This information therefore only concerns one of the non-polar aliphatic chains of gangliosides. No statement is made about the other non-polar aliphatic chain and the sugar unit. This other aliphatic chain can be known and / or of any nature.
- the statement C20: 0 denotes an acyl group with 20 C atoms (the carbon atom of the CO group is counted here) without a double bond (: 0).
- the C20: 0 fatty acid makes up 10 to 15% by weight.
- all intermediate values, all narrower ranges and in particular all integer intermediate values are included and disclosed, e.g. B. 1 1, 12, 13 and 14 wt .-%.
- the weight ratio of the C18: 0 acyl fatty acid in the group -CO-R 1 to the C20: 0 acrylic fatty acid in the group -CO-R 1 is 1.0 to 3.0.
- This range specification also includes all intermediate values, all narrower ranges and in particular individual values, for example 1, 1, 1, 2, 1, 3, 1, 4, 1, 5, 1, 6, 1, 7, 1, 8, 1, 9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8 and 2.9.
- the ganglioside mixture according to the invention can be obtained on the basis of animal (the term “animal” or “animal” used here does not refer to humans and also no sources of human origin) and / or vegetable lipid extracts and / or synthetically produced gangliosides, including those obtained from fungi and unicellular organisms ,
- the gangliosides can be modified from the lipid extracts given above.
- lipid extracts of this type with isolates of gangliosides with an enriched fatty acid specification. It is also possible to add chemically synthesized gangliosides to such lipid extracts.
- the gangliosides that make up the mixture can be made entirely synthetic. It is also possible to combine different types of modifications and / or productions with one another. However, it is preferred to start from native gangliosides. These can then be modified.
- the mixtures according to the invention are thus preferably composed of native unmodified gangliosides which are mixed with gangliosides were obtained from native gangliosides and then modified. Some of the options for modification are listed below:
- N-Deacylase EC 351 - new specific fatty acid esterification by acid / alkaline catalyzed chemical esterification or specific fatty acid derivatization according to Anand, J.K., Sadozai, K.K., Hakomori, S. Lipids 1996, 31, 995-998 using free fatty acids.
- the biological activity of the gangliosides can be increased by modifying the acyl fatty acids in the sense of the invention. This increase in biological activity applies to the most diverse functions of gangliosides. If, for example, a ganglioside has a certain biological activity, the change or modification of the lipid content without, for example, changing the sugar unit increases the corresponding, already existing biological activity. This is due to the fact that the inventive modification of the lipid portion of the gangliosides improves the mobility of the molecule in the membranes.
- receptor-mediated signals influences cell surface receptors
- the activity of ion channels e.g. Na / K ATPase
- membrane-bound enzymes e.g. phosphokinase C
- gangliosides can be increased by modifying the lipid content (more precisely the acyl fatty acids).
- the ganglioside mixture according to the invention can be used both in pure form and in the form of an emulsion, in particular an aqueous emulsion.
- the ganglioside mixture can also be used together with other lipids, it being assumed that the further lipids do not influence the biological activity of the ganglioside mixture or the gangliosides which make it up. This means that the biological activity of the gangliosides is only influenced by the fatty acids in the lipid component of the ganglioside, but not by the fatty acids that are also used.
- the ganglioside mixture according to the invention can be added to any conventional food and also to a pharmaceutical, insofar as it is expedient.
- the invention also relates to food, dietetic and pharmaceutical compositions which contain a ganglioside mixture according to the invention.

However, it is expedient to use agents which are suitable for oral or lingual administration and are formulated in accordance with the mode of administration.
- a ganglioside-containing mixture or a ganglioside-containing agent of the type described here contains a ganglioside mixture according to the invention, it is only necessary to determine the amount of gangliosides belonging to general formula I and then to analyze whether the specifications given here relate to the acyl group -CO-R1 are fulfilled.
