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). Development of systems using phenylboric acid with values PKalower than the most common of its commercially available derivatives of (3-AMINOPHENYL)boronic acid (PKa8,75) would be desirable, as would make possible the fixation of various biomolecules under physiological conditions (pH of 7.2), significantly increasing kolichestvennoi acid, include:







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.

FeNi is imidom with subsequent condensation in the presence of a diamine, preferably selected (but without limitation) from the group consisting of 1,4-butanediamine, 1,6-hexanediamine and 2,2'-dithiodipyridine (H2NCH2CH2SSCH2CH2NCH2).

Bioconjugation complexes receive buffer aqueous solutions of compounds, preferably selected (but without limitation this choice) from the group consisting of acetate, citrate, phosphate and carbonate buffers. You should not use borate and Tris buffers due to their ability to complex formation, respectively, with complexing remnants of phenylboric acid and the remnants of phenylboric acid. Bioconjugation complex is formed within 1-15 minutes at room temperature. The reaction is insensitive to fluctuations in ionic strength in the range from 0.01 to 2 Modernista. The stability of the complex increases with increasing temperature and is limited only by the volatility of the buffer. The addition of organic solvents, including acetonitrile, methanol, ethanol, isopropanol, butanol, N,N-dimethylformamide and dimethylsulfoxide, contributes to the stabilization bioconjugates. Chaotrope reagents (denaturant protein) including urea, guanidine hydrochloride and formamid, also contribute to further stabilization bioconjugates, e is W ith a salting out, dialysis, chromatography classification by size and by electrophoresis. Bioconjugation complexes are stable during storage after removal of water and can be dried.

Ionization phenylboric acid is an important factor in education bioconjugation complexes, for after her baratarian change the configuration with a triangular (with an average value of the angle between the bonds 120oand average length of ties) tetrahedral (with an average value of the angle between the bonds 109oand average length of ties). Phenylboric acid have PKavarying in the range of about from 5.2 to 9.2. Bioconjugation complexes of General formulas I, III, IV, VI, VII, VIII and IX, obtained from (4-carboxyphenyl) of boric acid are the values of the PKain the range of about 6.5 to 7.5. Bioconjugation complexes of General formulas I, II, IV, V, VI, VII and VIII, obtained from (3-AMINOPHENYL) boronic acid matter PKawithin approximately 8 to 9. Complexes of General formulas I, II, IV, V, VII and IX, obtained from (3-amino-2-nitrophenyl)boronic acid, (3-amino-5-nitrophenyl)boronic acid or (3-amino-6-nitrophenyl) boronic acid have intermediate values PKa. As a rule, RK

Bioconjugation complexes of formulas I, II and III (i.e., such that Q and Q' are preferably chosen from O, S and NH, a Y and Y' preferably O or NH) and in which phenylboronic reagent was obtained from (3-AMINOPHENYL) boronic acid, are stable in buffered aqueous-alkaline solutions with a pH in the range of about 8,5-11,5. Similarly, bioconjugation complexes of General formulas IV, V and VI (i.e., in which the groups X and X' is preferably selected from N, CH2and C6H5and the groups Y and Y' from O and NH) and in which phenylboronic reagent was obtained from (3-AMINOPHENYL) boronic acid, are stable in buffered aqueous-alkaline solutions with a pH in the range of about 8,5-11,5. Stability within the limits of pH is due to the fact that only phenylboronic creates a stable complex. However, at pH above 11.5 complex unstable due catalyzed by bases hydrolysis. Bioconjugation complexes, which are stable only in alkaline medium, can be used for reversible conjugation, in which these complexes can be decomposed by setting the appropriate pH.

Bioconjugation complexes of formulas I, II and III (i.e. as Q, Q', Y and Y' preferably taken On), in which phenylboronic reagent was obtained from (3-AMINOPHENYL) Bernieres aqueous solution in a wide range of pH, approximately from 2.5 to 11.5. It is believed that the stability of such a broad range of pH due to the presence of coplanar 1,3-diol residue associated with the enol form of the remainder of the 2-hydroxyanthraquinones. On the other hand stability in a wide pH range may be the result of low effective PKaphenylboric acid complex, due to the reaction of the anion of hydroxymandelate (SLEEP-HE) phenylboric acid and occurs, in the end, donor communications, filling the outer electron shell of the boron atom. Education bioconjugation complexes of this type are usually irreversible, as they can be decomposed only at pH above the 11.5 or below 2.5 or competitive decomposition in borate buffer solution.

Phenylboronic complexing polyconjugated with protein as a bioactive ingredient can be characterized by the number of lateral phenylboronic complexing residues per molecule of protein (degree of substitution). Polyconjugated you can handle the excess fluorescent phenylboronic reagent in the buffer aqueous solution with an appropriate pH, in order to obtain the above-described Bogatov phenylboric acid can be characterized by the reaction with an excess of fluorescent phenylboronic complexing reagent in the buffer aqueous solution with an appropriate pH, in the end, which receive bioconjugation complexes of formula I, IV or VII, where BAS* is a fluorescent moiety (fluorophore).

Suitable fluorophore is preferable to choose (but not limited to selection from the group consisting of fluorescein, rhodamine X, tetramethylrhodamine, Texas red, phycoerythrin and allophycocyanin. After removal of excess reagent by salting out, dialysis, or chromatography classification by size bioconjugation complex is subjected to spectrographic analysis and determine the number of complexing residues phenylboric acid residues or phenylboric acid relative absorption at 280 nm, which defines the full concentration of the protein, the absorption at the wavelength characteristic of fluorophore (1 max). Polyconjugated obtained with other vysokoparnymi bioactive ingredients that can be cleaned by salting out, dialysis, or chromatography classification by size, can be characterized in a similar way.
