Definitions
- the invention relates to a saccharide library, processes for producing such and their use.
- active ingredients e.g. B. Therapeutics on a saccharide basis. This is especially true if the active ingredients
- Agonists or antagonists of Zeil receptors are said to be. So far, however, it has been extremely difficult to provide saccharide-based drugs, i.e. to find those that exactly match target proteins, e.g. Receptors, react.
- the present invention is therefore based on the object of providing an agent with which active substances based on saccharide can be found.
- the invention thus relates to a saccharide library with different saccharide-containing molecules, the saccharide-containing molecules each comprising a core molecule with at least two functional groups and at least two saccharides.
- saccharide library means a variety, e.g. at least 6, preferably at least 20, particularly preferably at least 50 and most preferably at least 100 of different saccharide-containing molecules. These molecules can be unbound or attached to a carrier. All matrices suitable for use in the
- Solid phase chemistry can be used, such as solid phases based on poly styrene, polyethylene glycol, diatomaceous earth, CPC (controlled pore ceramics), cellulose and glass.
- core molecule with at least two functional groups encompasses aliphatic compounds which have at least two, in particular
- core molecules are cyclic aliphates. Representatives of these are C 6 cycloalkanes, such as trihydroxycycloalkanes, for example 1, 3, 5-trihydroxycycloalkanes, in particular 1, 3,5-trihydroxycyclohexane, inositols, in particular myo-inositol, and C 5 cycloalkanes, such as tri- and tetrahydroxycykiopentanes and derivatives thereof.
- Core molecules are also heterocyclic hydroxy compounds.
- core molecules are aliphatic amines, such as triamines, in particular methylene triamines, and pentaerythritol. Particularly preferred core molecules are shown in Fig.
- Steroids, methyl cholates and saccharides are not core molecules in the sense of the invention.
- saccharide includes saccharides of all kinds in all stereoisomeric and enantiomeric forms, especially monosaccharides, e.g.
- Pentoses and hexoses such as a- and ⁇ -D-glucose and a- and? -D-mannose, as well
- Saccharides here also include inositols, very particularly optically active derivatives of myo-inositol and quebrachitol, e.g. out
- Galactinols both from plant sources, such as sugar beet, and from milk products, or by enzymatic separation of enantiomers
- Saccharides are also glycoconjugates. These can be conjugates of
- glycoconjugates Z1 -Z1 0, a mixture of 1 0 glycoconjugates.
- the compounds Z1-Z10 are naturally occurring glycopeptides, glycoproteins and lipopolysaccharides. All of these compounds are of great biological interest because of their role in various immunological processes. An example of one is
- R amino acids e.g. Aspartic acid, lysine, glycine, alanine, etc. or fatty acids means.
- Derivatives of the above saccharides such as those with protective groups, e.g. Benzyl, protected saccharides and / or saccharides modified with functional groups such as amino groups, phosphate groups or haiogenide groups.
- the above saccharides can occur naturally or can be made synthetically.
- a saccharide-containing molecule preferably has 3, 4, 5 or 6 saccharides.
- the saccharides can be the same or different from one another. Also, several of the saccharides in the saccharide-containing molecule may be the same and one or more of the remaining saccharides may differ from one another.
- a saccharide can be a di, tri, or oligosaccharide and the rest are e.g. B. a monosaccharide. This is referred to as the saccharide background library (see FIG. 3).
- the saccharides can be bound to the core molecule at their functional groups. This is preferably done with the formation of an O-glycosidic bond.
- a spacer is present between the core molecule and one or at most all of the saccharides.
- examples of such are aliphatic compounds such as alkanes.
- the spacer can also be an unsaturated aliphatic compound.
- the spacer preferably has 3 to 10 carbon atoms.
- the spacer can be bound to the functional groups of the core molecule and / or the saccharides. If there are several spacers, these can be the same or different from one another.
- a saccharide-containing molecule present in the library according to the invention preferably has an organic compound.
- This can be the core molecule and / or be bound to one or more of the saccharides.
- organic compounds are alkanes with a functional group, e.g. B. a halogen, such as bromine, a hydroxy, azido and / or amino group, or alkenes, in particular with a terminal double bond.
- the alkenes can also have the above functional groups.
- the above organic compound preferably has 3 to 10 carbon atoms.
- one or more of the organic compound can be present. If there are several, these can be the same or different from one another. With the organic compounds it is possible, for example, to bind the saccharide-containing molecule to a support and / or dyes, magnetic particles and / or other components to the
- Bind saccharide-containing molecule Bind saccharide-containing molecule.
- the components of the saccharide-containing molecules are shown as starting materials. In the saccharide-containing molecules, however, they are in a derivatized form.
- a method for producing the above saccharide libraries is also provided.
- the individual components i.e. Core molecules, saccharides, possibly linkers, possibly organic compounds and possibly carriers are covalently linked to one another.
- a core molecule bound to a support is provided in which the functional groups have protective groups.
- the protecting groups can be orthogonal protecting groups. These protecting groups are characterized by the fact that they are isolated (selective), i.e. one by one, from one molecule
- the presence of other protective groups can be split off without these other protective groups being influenced by the split-off conditions.
- protecting groups are acyl groups such as benzoyl, acetyl and chloroacetyl, benzyl groups and silyl groups.
- acyl groups such as benzoyl, acetyl and chloroacetyl, benzyl groups and silyl groups.
- the person skilled in the art knows how they can be split off selectively.
- One of these protective groups is split off. Then it is reacted with a saccharide or a mixture of saccharides so that the saccharides attach to the functional group be bound. Then the next protecting group is selectively split off and the reaction is repeated.
- a new saccharide, a new mixture of saccharides or the saccharide or mixture of saccharides used in the above step can be used.
- A, B, C 3 different carbohydrates that can be coupled to the solid phase
- monosaccharides for example, can be bound to the core molecule. These can be the same or different from each other. One of these monosaccharides has a group capable of binding to another saccharide, for example an acetyl group. A saccharide different from the already bound saccharides is then bound at this point. Finally, the saccharide-containing molecules obtained can be split off from the support and, if desired, the protective groups which may be present on the saccharides. In this way, a saccharide background library can be obtained.
- a core molecule as described in FIGS. 2-4, can be glycosidated chemically and enzymatically.
- the latter takes advantage of the fact that glycosidases can transfer monosaccharides from activated donor saccharides (nitrophenylglycosides, glycals, glycosylfluorides, disaccharides etc.) to suitable acceptors (transglycosidation).
- the glycosides obtained are anomerically pure.
- a circular process in which the core molecule is continuously treated with a solution of glycosidase and donor sugar can achieve almost quantitative conversion.
- Glycosidases with broad donor specificity can be used in the form of combinatorial batch synthesis.
- a core molecule is e.g. reacted with a glycosidase and a mixture of different donor sugars.
- a saccharide library is obtained, the composition of which, inter alia, is determined by the specificity of the enzyme and the reactivity of the donor sugar. The methods suitable for the enzymatic binding of saccharides to core molecules and the materials required for this are
- Saccharide libraries according to the invention are distinguished in that they provide a large number of different saccharide-containing molecules. Furthermore, saccharide libraries according to the invention, in particular their
- saccharide libraries according to the invention are ideally suited for a screening method with which specific active substances can be fished out of the saccharide library.
- the procedure can be as follows: When developing a saccharide-based active ingredient that, for example, specifically reacts with a known receptor, one will use affinity chromatography, for example. For this purpose, the known receptor is immobilized, e.g. B. on a solid phase. By applying the saccharide library to this solid phase, only those saccharide-containing molecules that bind to the receptor are retained. All other saccharide-containing molecules are separated. Then all binding saccharide-containing molecules are eluted, for example by increasing the salt concentration of the solvent, and then analyzed.
- Branch libraries can e.g. B. can be obtained in the following way: According to the method described above, after the selective cleavage of a protective group (R.,), coupling with components A, B and C is carried out separately. This results in three pots, each of which is the first
