The invention relates to the field bioconjugation drugs, in particular to the class of complex compounds (complexes) phenylboric acid used in the conjugation of biological macromolecules, and to methods for obtaining and using such complexes.A descriptive term bioconjugate means linking chemical or biological means molecules of two or more species, of which at least one molecule is a biological macromolecule. This includes the conjugation of proteins, peptides, polysaccharides, VNIMI to bring useful properties, including radionuclides, toxins, haptens, inhibitors, fluorophores, ligands, etc. a Special kind of conjugation is the immobilization of biological macromolecules, when they are subjected to reversible or irreversible conjugation with an insoluble carrier. Bioconjugate widely used in research in the field of biochemistry, immunochemistry and molecular biology. Use bioconjugate numerous and include affinity chromatography, affinity cytochemistry, histochemistry, detection of abnormalities in tests, diagnostics, amplification of signals, immunoassay, hybridoma technology, technology batterbee, bioaffinity sensors, detection of genes in samples of cross-linking reagents, determination of affinity or its breach, the transport of drugs, reagents for embedding genes, immovable reagents, selective extraction, selective shutdown, flow cytometry and analysis of cytological samples.Existing methods of cooking bioconjugates include system Avidin-Biotin and Digoxigenin-anti-Digixigenin.So functional groups for conjugation listed bioactive ingredients are the following: (a) for proteins, it is known that the conjugates, basically, get with lysine and cysteine on the overall amino acid (D3-D5); b) for glycoproteins, including immunoglobulin, it is known that the conjugates can be obtained using protein groups, as described above, or by activation in relation to the hydrazide diol groups proteichisma intermediate hydrocarbon side chain of the macromolecule adjacent to the aldehyde residue (D6-D7, describing the covalent joining of glycoproteins to dihydroxyaluminum residue on the adjacent hydroxyl groups of glycoproteins); C) for peptides, it is known that the conjugates basically get the same as above conjugatum proteins by reaction with located on the side chain amine and thiol groups (D3); g) for polysaccharides, it is well known that the conjugates, mainly produced by interaction with neighboring diol groups of the molecule (D8); d) for toxins, ligands and haptens, including drugs and hormones, it is known that the conjugates, basically, get like described above, the conjugates of the protein through interaction with located on the side chain of the macromolecule amine and thiol groups (D3); and for nucleic acids, it is known that the conjugates, mainly get through modification of the oligonucleotides in the 5-position of the pyrimidine or 8 Polo is eficacia through condensation reactive groups of the protein (i.e., amine or thiol) on the phosphate group of liposomes (D8);
l) for radionuclides known that the nuclides can be done reactive with many functional groups, including amine and tirinya group proteins (D4);
m) for inhibitors of enzymes is well known that the conjugates basically get the same as above protein conjugates, through interaction of the side chain of the macromolecule amine and tylnej groups (D3);
about to fluorophores, it is known that fluorescent proteins attached similarly to proteins, all fluorophores are amines or modified content amines and can be conjugated to a similar proteins (D11, describes the properties of known fluorophores).p) for solid-phase substrate, it is known that the substrate can be reactivated for many functional groups, including amine and tirinya group proteins (D3).It is known that phenylboric acid interact with requisitioned properties of polar molecules of many species. It is known that complexes of different stability, containing 1,2-diols, 1,3-diols, 1,2-hydroxy acid, 1,3-hydroxy acid, 1,2-hydroxyamine, 1,3-hydroxyamine, 1,2-diketones and 1,3-diketones can be formed if the but (sorbents for chromatography can be used for selective extraction of samples of complex compounds of biological molecules, with requisitioning functional properties. Many important biological molecules, including carbohydrates, catecholamine prostaglandins, ribonucleotides and steroids, have requisitioned properties and, therefore, can be allocated in this way.Phenylboric acid like boric acid is a Lewis acid and ionizes not direct deprotonization and hydration, forming a tetrahedral phenylbutane (PKand=8,86). Phenylboric acid three times stronger than boric. Ionization phenylboric acid is an important factor in the formation of the complexes, because after ionization triangular configuration bretanion (with an average angle between the bonds 120oand average length of links 1,37 angstroms) enters the tetrahedral (with an average angle between the bonds 109othe average length of relationships








Now it is known that compounds having a CIS - or coaxial 1,2-diol and 1,3-disfunctionally group and, in particular, carbohydrates can form complexes with the immobilized phenylbutanone in the form of cyclic ethers only in aqueous-alkaline medium. It is known that the oxidation of 1,2-diol and 1,3-diastereomer complexes releases diols, due presumably due to the tension of the hydrolysis cycle of five-membered cyclic ether phenylboric acid, including triangular coordination of the boron atom. Coplanar aromatic 1,3-diols, like 1,8-dihydroxynaphthalene known to form complexes even in the acidic environment due to the hydrolytic stability of the six-membered cyclic ethers phenylboric acid. It is also known that substituted phenols with side residues of 1,3-hydroxyamide, 1,3-hydroxyamine and 1,3-hydroxyxine come in aqueous-alkaline medium in the reversible complexation with borate buffer annah bioconjugate research and investment in this area, the selectivity of phenylboric acid was not still used for conjugation with biological macromolecules of one or several molecular types, can give products useful functional properties. Moreover, what is new is the use of capable of complexing immobilized components to obtain complexes with the remnants of phenylboric acid. Such use is of particular interest, for example, in cases where the balance of phenylboric acid is associated with such biological macromolecule, as the antibody, which may be due to complexing component by using the selectivity of the rest of phenylboric acid chelation.Used herein, the terms have the following meanings:
