Definitions
- the invention relates to a method for providing artificial receptors on a polymeric compound, preferably on a stabilized surface thereof, with binding sites for binding biologically or pharmacologically active substances by template-assisted optimization as a new way of producing customized chromatography materials via or on intelligent Surfaces
- the object of the invention is to provide a method by which the template, which at least partially corresponds to a biologically or pharmacologically active compound in terms of conformation and configuration, binds the template to a polymer compound by binding the template to the Controlling the polymer connection to the ligands to be coupled
- the configuration and conformation of the template as a so-called negative image should be shaped by the ligands coupled to the polymer compound, for example by the coupling of certain ligands whose molecular size and conformation should also the negative image as information about the conformation and configuration of the template can be shaped permanently or briefly as a so-called short-term or long-term memory on the polymer compound by the ligands bound to the polymer compound.
- the receptors formed by the ligands should serve as information stores
- the invention relates to a method for providing artificial receptors on a polymeric compound, preferably on a stabilized surface thereof, with binding sites for binding biologically or pharmacologically active substances by a) immobilizing template molecules which are biologically or pharmacologically active compounds the polymeric compound, b) coupling reactive functional groups to the polymeric compound to bind ligands under physiological conditions, c) binding of compounds as ligands to the reactive groups, d) preferably stabilizing the adjacent compounds bound to the reactive groups with one another for chemical stabilization of the ligands on the polymeric compound and e) detaching the template molecules.
- the process I according to the invention can preferably be used to provide artificial receptors on a polymer compound for binding biologically or pharmacologically active substances which are a template, preferably on stabilized surfaces of a polymeric compound, which is characterized in that a) a polymer compound for aminopropylation with a chloropropylamine dissolved in MeOH in one heating step, preferably in a microwave reactor with 600 watts irradiated for 1 to 4 minutes, preferably irradiated for a further 4 minutes, and then dried after washing with aqueous acetic acid and aqua bidest, b ) the polymer compound with aminopropyl groups to produce activated polymer compound with a square acid ester compound and triethylamine dissolved in MeOH at RT for 1 to 24 hours, incubated and air-dried after washing with ETOH, c) the polymer Connection to represent a polymer dendrime r- compound with a dendritic polymer and triethylamine dissolved in MeOH
- the method according to the invention enables the immobilization of template molecules by means of covalent bonding or non-covalent bonding such as electrostatic interaction e.g. ion binding, hydrophobic binding or the like can be carried out on the surface of the polymeric compound.
- the method II according to the invention for providing artificial receptors on a polymer compound for binding biologically or pharmacologically active substances which are a template, preferably on stabilized surfaces of a polymer compound can be characterized in that a) the polymer compound for the preparation of activated polymer compound with a squaresate compound and triethylamine dissolved in MeOH at RT for 1 to 2 hours and air-dried after washing with MeOH, b) the activated polymer compound to increase the the polymer compound-bound amino groups are incubated with polyethyleneimine in MeOH and air-dried after washing with MeOH, c) then the polymer compound to prepare highly activated polymer compound with a squarate ester compound and triethylamine dissolved in MeOH at RT 1 to Incubated for 24 hours and air-dried after washing with MeOH, d) the highly activated polymer compound for the preparation of polymer compound containing a glucose-nototated surface with glucosamine dissolved in MeOH at
- Cellulose membrane, glass, plastic surface, preferably microtiter plates, a dendrimeric compounds, or dendritic polymers or a lipid membrane with OH groups can preferably be used as the polymer compound.
- Amino acids, nucleotides, nucleosides are suitable for the processes I and II according to the invention.
- the compound can be a cellulose compound, such as a cellulose membrane filter (Schleicher-Schull). Any small-molecule compounds or high-molecular compounds such as coenzyme A, dyes (see exemplary embodiments) are suitable as the template compound
- step a) of process II the polymer compound for aminopropylation after heating to 70-90 ° C. with methanolic bromopropyl phthalimide solution in the presence of NaOH is incubated for 60 to 120 minutes and then after washing with aqueous acetic acid and be dried aqua bidest
- the method according to the invention for providing artificial receptors is also intended to enable adequate stabilization thereof without loss of time due to the transfer of the polymer compound substituted by methods I and II into hermetically sealed vessels in order to avoid hydrolysis and oxidation, which is achieved in that the polymer compound activated with step b of process I in order to check the activity of the activated polymer dendrimer compound for 1 to 104 weeks at pH 5.5 to 6.5 without cyclodextrins and even more than 104 weeks in the presence of cyclodextrin compound as Stabilizer can be left at RT.
- Stage B addition of different ligands which can be reversibly covalently arranged around the template molecules under the incubation conditions. These immobilization steps are strictly reversible and thus create an important competitive situation.
- This stage can be called the optimization phase.
- the highlighted lines symbolize the optimized, supramolecular interaction .
- the more optimal the non-covalent interaction the longer the corresponding ligands stay on the surface.
- the situation may well arise that an existing optimal interaction becomes suboptimal due to the binding of a further ligand and this ligand must then be replaced by another, to create a stronger interaction in the dressing
- the ligand population influences or determines individual interactions
- Step C After optimization has been completed, the ligands are chemically stabilized. This step irreversibly shapes the dynamic process chemical fixation of the ligand arrangement is an essential prerequisite for the construction of artificial receptors.
- Step D After the ligands have been chemically fixed, the templates are removed in a targeted manner and a surface is obtained in which artificial receptors are embedded. This customized surface should be seen as an optimized supramolecule in which individual receptors are distributed.
- a surface is used as an anchor for the dynamic imprinting process. All surfaces that allow functionalization chemistry are possible, e.g. Cellulose membranes, glass, functionalized plastics or gold surfaces. There are also no limits to the size and shape of the surface structures. Planar surfaces, beads, colloidal gold, nanoparticles, fullerenes or surfaces of dendrimer structures can be used as a compartment. We suspect that microstructures with concave cavities on surfaces can be particularly important with this method.
- the surface used for "reversible imprinting" has more than just a carrier function. It is conceivable to use this method on (in) lipid membranes, such as liposomes or other interfaces. Here, these influences can play a dominant role in the formation of the supramolecular
- the particular advantage of this new technology is that it can be used in very small compartments as well as on very large surfaces.
- the imprinting processes should take place under physiological conditions, that is to say in watery systems.
- Knowledge of the reactivity with respect to the ligands and about possible undesirable competitive reactions of the active components during the imprinting processes is of great importance.
- This reactivity is of great importance is used to fix the ligands around a template molecule chemically via amide bonds after the supramolecular optimization phase has taken place.
- the undesirable competitive reaction for ligand fixation is the hydrolysis of the squares esters to squares acid.
- the cyclodextrins can be detached by competition with, for example, p-toluenesulfonic acid or other hosts and thus simply removed and reactivated for the imprinting process
- sterile components While solutions can easily be sterile filtered, this is not possible with solid phases such as cellulose membranes.
- Figure 3 shows an example of immobilized dendrimers on surfaces.
- the "D” represents the dendrimer molecule on which 63 amino groups are distributed in a radial symmetry. These remaining amino groups (an amino group is used for coupling with the surface) can be used for the immobilization of the template molecules or the functional groups Groups are used for the reversible ligand binding.
- This reduplication strategy for functional groups can be used for any polyamines, such as, for example, polyethyleneimine, polyvinilimmin, chitosan, polylysine, etc.
- any embodiments of surfaces such as, for example, amino-functionalized microtiter plates, amino-functionalized gold surfaces, amino-functionalized glass, amino-functionalized carbon (electrodes, nanoparticles), amino-functionalized magnetic particles etc.
- amino groups on surfaces Reduplication is an important prerequisite for the production of artificial receptors with high ligand densities.
- Figure 4 shows an example of a section of a surface with a high density of chemically reactive squarester groups. This reactive surface is surprisingly well suited for producing membranes with a high density of artificial receptors using the imprinting process described above.
- Figure 5 shows this class of compounds of highly substituted bicyclic anhydrides. These bicyclic, rigid chemical structures consist of three important structural elements (see Figure 5):
- Figure 7 is intended to summarize, without a limitation making the principle of reversible imprinting clear using a specific chemical example.
- the template molecule is first covalently linked to the dendrimer under controlled conditions.
- the chemistry is selected so that once the ligand arrangement has been fixed, one is fixed targeted cleavage, for example with mercaptoethanol, is possible
- the bicyclic anhydrides are stably linked with the remaining amino groups via a side chain.
- ligands e.g. amino acids, oligopeptides and peptide fragments
- reaction conditions for this are too choose that cooperative effects between ligands and templates (and between the different ligands) can cause the reaction kinetic network to form the most thermodynamically stable ligand arrangement after the formation of the supramolecule the imide formation is then initiated by a pH shift to 8 5-9 5 (see Figure 6).
- the templates can be detached from the dendrimer surface using disulfide-cleaving reagents
- the process I according to the invention makes it possible, by coupling a bicyclic anhydride compound to the polymer dendrimer compound connected to the template and activating the anhydride functionality, that the z. B.
- the template coupled to the polymer compound which at least partially corresponds to a biologically or pharmacologically active compound in terms of conformation and configuration, determines the extent of the binding, the binding site of the Ligands and the ligands as such.
- the template also serves as the template for the reversible connection of the ligands
- the ligands coupled to the anhydride-dendmer compound as a negative image of the template indicate the configuration and conformation of the template.
- This information can be briefly at pH 7 as short-term memory or, if the pH is increased to 8.5, an irreversible imide bond, also called called chemical fixation step or stabilization step, cause the irreversible imide bond is permanent and is equivalent to long-term secured information about the template as long-term memory.
- the information can be controlled by varying the incubation conditions with ligands, such as time, incubation duration, temperature, pH Change in temperature of ligands L 4 already coupled, which led to a coupling of L5, displaced by ligands L9 at pH 7 and these enable the coupling of the L10, so that, as with an electronic data storage device or data storage, the information to be stored is quasi-scanned can be written and thereby changed
- a deletion - as a partial deletion - of the information provided as a reversible binding of the ligands is carried out by lowering the pH of the incubation with ligands to, for example, 5.0 in order to recycle the dedrimer coupled to the polymer-dendrimer compound.
- a complete deletion - complete deletion- of the information is carried out by detaching the template from the polymer-dendrimer compound, in that the bond based on, for example, electrostatic interaction, such as ionic bond, hydro- phobic binding or the like, the template is changed by changing the composition and / or concentration of the incubation batch.
- methods I and II according to the invention provide a chemical data store which is also able to record information, also in digitized form.
- method II relates to the irreversible coupling of ligands to polymer dendrimer compounds as a function of the template, cyclodextrins, pH, concentrations, temperature, incubation duration, composition of incubations as protective groups being able to control reactions as well.
