Definitions
- the present invention relates to special low-molecular compounds which are suitable for forming aggregates by intermolecular association.
- the present invention also relates to aggregates comprising such compounds, and to methods for producing such aggregates.
- the invention further relates to special uses of the compounds and aggregates, in particular for therapeutic and diagnostic purposes.
- Multivalent interactions are very widespread in biology, and the interacting units can have ligands such as oligosaccharides, proteins, nucleic acids or lipids. Multivalent interactions are characterized by a large number of individual weak monovalent bonds, which are often preferred in biological systems over a single strong monovalent bond (M. Mammen, S-K. Choi, G. M. Whitesides, Angew. Chemie, 110, 2908, 1998).
- Multivalent inhibitors are those in which several ligands are covalently attached to a low molecular weight support (LL Kiesling, NL Pohl, Chemistrv & Biolo ⁇ v. 3, 71, 1996; GD Glick, PL Toogood, DC Wiley, JJ Skehel, JR Knowles, J. Biol Chem., 266, 23660, 1991) or to a dendrimer (D. Zanini, R. Roy, J. Org. Chem., 63, 3486, 1998). In these cases, however, the specific binding affinity is increased only slightly.
- WO 98/14215 discloses glucoconjugates as inhibitors of viral cell adhesion.
- the compound [Neu5Ac ⁇ 2-6Galß1-4GlcNAcß1-NHCOCH 2 NH-CO (CH 2 ) 4 CO- (NHCH 2 -CO) 3 -NHCH 2 -] 4 C is disclosed.
- this compound does not form aggregates in aqueous solution.
- multivalent inhibitors are also known in which the active ligands are bound to a polymeric carrier. These compounds show increased efficiency compared to the corresponding monomeric ligands.
- a multivalent polymer-based inhibitor affects this interaction (monovalent: K D ⁇ 2 xl O ⁇ M, multivalent: K D ⁇ 3 x 10 _7 M; A. Jonstein et al., J. Am. Chem. Soc, 113, 686, 1991).
- the multivalent polymer inhibitors known to date are also unsuitable for therapeutic use.
- the disadvantages are due to the polymer carrier molecules used and their properties.
- High polymers (60-70 kDa) are no longer effectively filtered by the kidney, and their breakdown by the liver can lead to intolerance due to the formation of toxic metabolites.
- Patent applications EP 601417 and WO 95/34673 describe polymer-based carbohydrate receptor blockers which are physiologically compatible as a whole molecule and as degradation products. These properties are achieved through the use of biodegradable polymers. However, these products also have a fundamental disadvantage for use as a pharmaceutical, because in practice polymers are not pure and precisely defined compounds, but rather consist of complex mixtures of compounds of different molecular sizes. This fact makes the use (approval) of such a polymeric inhibitor as a medicament extremely difficult.
- Another group of multivalent inhibitors are compounds in which the ligands are bound to the surface of liposomes. Liposomes have the disadvantage that their lipophilic components can enter into unspecific interactions, e.g. through the installation in cell membranes.

- terminal groups R are selected so that aggregates are obtained which, on the one hand, interact with suitable receptors via suitable ligands through polyvalent interactions and, on the other hand, contain marker units. This makes the polyvalent interactions accessible for detection and the compounds can be used in a diagnostic procedure.
- the aggregates can be constructed from compounds of the formula (I) which contain both ligand and marker residues.

- terminal groups are also advantageously linked via the active ester method to the compounds of the general formula (I) synthesized according to scheme 1 (scheme 2).
- Fig. 3 shows the influence of the temperature and the presence of urea on the
- the aggregates are high-molecular, non-covalent polymers that are formed by self-assembly of compounds of the general formula (I) (Scheme 3).
- the non-covalent nature of the bonds between the compounds of the general formula (I) causes the reversibility of the aggregate formation and, when the external conditions change, enables the aggregates to dissociate to compounds of the general formula (I) or their conversion into other aggregates, in each case in In terms of the formation of the most thermodynamically stable structures.
- the external conditions which determine the formation of the aggregates and the course of the intermolecular association include, in addition to the temperature, the pH and the type and composition of the solvent. It was shown by light scattering studies that the compound [HCl H-Gly 7 -NHCH 2 -] 4 C (22a) is present in water at 20 ° C in an unassociated form, but by adding a 0.8 M NaHC0 3 solution Self-association of the connection is achieved. The association can then be reversed by adding HCI (see Example 9).
- the formation of aggregates is also influenced by the presence of components which can interact with the compounds of the general formula (I). These can be organic molecules, e.g. B. Compounds of formula (III), urea ( Figure 3), trifluoroethanol, methanol, acetone or other organic solvents. There may also be other compounds of the general formula (I) or (III) which on their own - under the given conditions - do not form any associates.
- the process of self-association is also influenced by the interactions between the ligands and the corresponding receptors.
- This influence can e.g. B. consist in the fact that only the presence of the receptors causes an association of compounds of the general formula (I), under conditions in which no association of these compounds would otherwise take place.
- the reversibility of the aggregate formation also makes it possible for aggregates to change in the presence of receptors while rearranging or changing the composition in such a way that a thermodynamically favorable state of the overall system consisting of aggregate and receptor is achieved.
- the aggregates can therefore adapt to different receptor arrangements and thus optimize an interaction between the receptors and ligands. This optimization through subsequent adaptation of the polyvalent interactions represents a significant advantage over the prior art.
- Tables 2 and 3 show the influence of the matrix structure on the inhibition of viral cell adhesion by influenza viruses, measured in a fetuin binding assay known to the person skilled in the art. Doing so reinforces the specific activity of the inhibitor by more than three orders of magnitude compared to the activity of the free ligand Neu ⁇ Ac ⁇ Bn in the case of the aggregate ⁇ [Neu5Ac-Gab-Ad-AC 3 -Gly 5 -NHCH 2 -] 4 C ⁇ X (44).
- Another example of the increase in the biological activity of a biological ligand by its binding to an aggregate is the compound ⁇ [B dr Ap-Ad-AC 3 - Gly g -NHCH 2 -] 4 C ⁇ X (49) as an inhibitor of cytotoxicity of human blood sera against the pig kidney kidney cells PK15.
