Abstract
Two forms were found in the NMR spectra of N6-substituted 2-chloroadenosines. The proportion of the mini-form was 11-32% of the main form. It was characterized by a separate set of signals in COSY, 15N-HMBC and other NMR spectra. We assumed that the mini-form arises due to the formation of an intramolecular hydrogen bond between the N7 atom of purine and the N6-CH proton of the substituent. The 1H,15N-HMBC spectrum confirmed the presence of a hydrogen bond in the mini-form of the nucleoside and its absence in the main form. Compounds incapable of forming such a hydrogen bond were synthesized. In these compounds, either the N7 atom of the purine or the N6-CH proton of the substituent was absent. The mini-form was not found in the NMR spectra of these nucleosides, confirming the importance of the intramolecular hydrogen bond in its formation.

Abstract
A number of purine arabinosides containing chiral amino acid amides at the C6 position of the purine were synthesized using a transglycosylation reaction with recombinant E. coli nucleoside phosphorylases. Arsenolysis of 2-chloropurine ribosides with chiral amino acid amides at C6 was used for the enzymatic synthesis, and the reaction equilibrium shifted towards the synthesis of arabinonucleosides. The synthesized nucleosides were shown to be resistant to the action of E. coli adenosine deaminase. The antiproliferative activity of the synthesized nucleosides was studied on human acute myeloid leukemia cell line U937. Among all the compounds, the serine derivative exhibited an activity level (IC50 = 16 μM) close to that of Nelarabine (IC50 = 3 μM) and was evaluated as active.

Abstract
During the preparative synthesis of 2-fluorocordycepin from 2-fluoroadenosine and 3′-deoxyinosine catalyzed by E. coli purine nucleoside phosphorylase, a slowdown of the reaction and decrease of yield down to 5% were encountered. An unknown nucleoside was found in the reaction mixture and its structure was established. This nucleoside is formed from the admixture of 2′,3′-anhydroinosine, a byproduct in the preparation of 3-′deoxyinosine. Moreover, 2′,3′-anhydroinosine forms during radical dehalogenation of 9-(2′,5′-di-O-acetyl-3′-bromo- -3′-deoxyxylofuranosyl)hypoxanthine, a precursor of 3′-deoxyinosine in chemical synthesis. The products of 2′,3′-anhydroinosine hydrolysis inhibit the formation of 1-phospho-3-deoxyribose during the synthesis of 2-fluorocordycepin. The progress of 2′,3′-anhydroinosine hydrolysis was investigated. The reactions were performed in D2O instead of H2O; this allowed accumulating intermediate substances in sufficient quantities. Two intermediates were isolated and their structures were confirmed by mass and NMR spectroscopy. A mechanism of 2′,3′-anhydroinosine hydrolysis in D2O is fully determined for the first time.

Abstract
In the present work, we suggested anion exchange resins in the phosphate form as a source of phosphate, one of the substrates of the phosphorolysis of uridine, thymidine, and 1-(β-ᴅ-arabinofuranosyl)uracil (Ara-U) catalyzed by recombinant E. coli uridine (UP) and thymidine (TP) phosphorylases. α-ᴅ-Pentofuranose-1-phosphates (PF-1Pis) obtained by phosphorolysis were used in the enzymatic synthesis of nucleosides. It was found that phosphorolysis of uridine, thymidine, and Ara-U in the presence of Dowex® 1X8 (phosphate; Dowex-nPi) proceeded smoothly in the presence of magnesium cations in water at 20-50 °C for 54-96 h giving rise to quantitative formation of the corresponding pyrimidine bases and PF-1Pis. The resulting PF-1Pis can be used in three routes: (1) preparation of barium salts of PF-1Pis, (2) synthesis of nucleosides by reacting the crude PF-1Pi with an heterocyclic base, and (3) synthesis of nucleosides by reacting the ionically bound PF-1Pi to the resin with an heterocyclic base. These three approaches were tested in the synthesis of nelarabine, kinetin riboside, and cladribine with good to excellent yields (52-93%).

Abstract
A series of ribo- and deoxyribonucleosides bearing 2-aminopurine as a nucleobase with 7,8-difluoro- 3,4-dihydro-3-methyl-2H-[1,4]benzoxazine (conjugated directly or through an aminohexanoyl spacer) was synthesized using an enzymatic transglycosylation reaction. Nucleosides 3-6 were resistant to deamination under action of adenosine deaminase (ADA) Escherichia coli and ADA from calf intestine. The antiviral activity of the modified nucleosides was evaluated against herpes simplex virus type 1 (HSV-1, strain L2). It has been shown that at sub-toxic concentrations, nucleoside (S)-4-[2-amino-9-(β-D-ribofuranosyl)-purin-6-yl]-7,8-difluoro-3,4-dihydro-3-methyl-2H-[1,4]benzoxazine exhibit significant antiviral activity (SI > 32) on the model of HSV-1 in vitro, including an acyclovir-resistant virus strain (HSV-1, strain L2/R).

Abstract
The novel isosteric ribavirin analogues were synthesized by two different ways. Some of them showed significant antiviral action against hepatitis C virus (HCV), herpes simplex (HCV-1) and influenza A virus comparable to that of ribavirin itself. The data obtained confirm the proposed theory of the ribavirin possible antiviral activity mechanism related with bioisosterism.

Abstract
The trans-2-deoxyribosylation of 4-thiouracil (4SUra) and 2-thiouracil (2SUra), as well as 6-azauracil, 6-azathymine and 6-aza-2-thiothymine was studied using dG and E. coli purine nucleoside phosphorylase (PNP) for the in situ generation of 2-deoxy-α-D-ribofuranose-1-phosphate (dRib-1P) followed by its coupling with the bases catalyzed by either E. coli thymidine (TP) or uridine (UP) phosphorylases. 4SUra revealed satisfactory substrate activity for UP and, unexpectedly, complete inertness for TP; no formation of 2'-deoxy-2-thiouridine (2SUd) was observed under analogous reaction conditions in the presence of UP and TP. On the contrary, 2SU, 2SUd, 4STd and 2STd are good substrates for both UP and TP; moreover, 2SU, 4STd and 2'-deoxy-5-azacytidine (Decitabine) are substrates for PNP and the phosphorolysis of the latter is reversible. Condensation of 2SUra and 5-azacytosine with dRib-1P (Ba salt) catalyzed by the accordant UP and PNP in Tris∙HCl buffer gave 2SUd and 2'-deoxy-5-azacytidine in 27% and 15% yields, respectively. 6-Azauracil and 6-azathymine showed good substrate properties for both TP and UP, whereas only TP recognizes 2-thio-6-azathymine as a substrate. 5-Phenyl and 5-tert-butyl derivatives of 6-azauracil and its 2-thioxo derivative were tested as substrates for UP and TP, and only 5-phenyl- and 5-tert-butyl-6-azauracils displayed very low substrate activity. The role of structural peculiarities and electronic properties in the substrate recognition by E. coli nucleoside phosphorylases is discussed.

Abstract
Thymosin β4 is a 43 amino acid long peptide with an acetylated N-terminal serin that has a high potential as a remedy for healing ulcers, wounds and burns. Although protein biosynthesis offers attractive opportunities in terms of a large-scale production, currently thymosin β4 is mainly produced by chemical synthesis. The problems that hinder the successful commercialization of the biotechnological approach are associated with the small peptides expression and N-terminal acetylation. This work presents an innovative biotechnological method for thymosin β4 production that employs the peptide acetylation in vivo. A genetically engineered construct was created, where the Tβ4 coding sequence fused with the intein Mxe GyrA sequence and chitin-binding domain was combined with the acetyltransferase coding sequence to form a polycistronic construct under a stringent control of T7 promoter. This plasmid construct provided for the expression of the Tβ4-intein fusion protein. In the process of the post-translational modification in vivo formyl methionine was completely removed from the target peptide N-terminus and followed by the Tβ4 precursor N-terminal acetylation. The use of the intein-mediated expression system made it possible to extract thymosin β4 in only 2 chromatographic runs. The method is straightforward to implement and scale up.

Abstract
Two approaches to the synthesis of 2-chloro-9-(2-deoxy-2-fluoro-β-D-arabinofuranosyl)adenine (1, clofarabine) were studied. The first approach consists in the chemical synthesis of 2-deoxy-2-fluoro-α-D-arabinofuranose-1-phosphate (12a, (2F)Ara-1P) via three step conversion of 1,3,5-tri-O-benzoyl-2-deoxy-2-fluoro-α-D-arabinofuranose (9) into the phosphate 12a without isolation of intermediary products. Condensation of 12a with 2-chloroadenine catalyzed by the recombinant E. coli purine nucleoside phosphorylase (PNP) resulted in the formation of clofarabine in 67% yield. The reaction was also studied with a number of purine bases (2-aminoadenine and hypoxanthine), their analogues (5-aza-7-deazaguanine and 8-aza-7-deazahypoxanthine) and thymine. The results were compared with those of a similar reaction with α-D-arabinofuranose-1-phosphate (13a, Ara-1P). Differences of the reactivity of various substrates were analyzed by ab initio calculations in terms of the electronic structure (natural purines vs analogues) and stereochemical features ((2F)Ara-1P vs Ara-1P) of the studied compounds to determine the substrate recognition by E. coli nucleoside phosphorylases. The second approach starts with the cascade one-pot enzymatic transformation of 2-deoxy-2-fluoro-D-arabinose into the phosphate 12a, followed by its condensation with 2-chloroadenine thereby affording clofarabine in ca. 48% yield in 24 h. The following recombinant E. coli enzymes catalyze the sequential conversion of 2-deoxy-2-fluoro-D-arabinose into the phosphate 12a: ribokinase (2-deoxy-2-fluoro-D-arabinofuranose-5-phosphate), phosphopentomutase (PPN; no 1,6-diphosphates of D-hexoses as co-factors required) (12a), and finally PNP. The substrate activities of D-arabinose, D-ribose and D-xylose in the similar cascade syntheses of the relevant 2-chloroadenine nucleosides were studied and compared with the activities of 2-deoxy-2-fluoro-D-arabinose. As expected, D-ribose exhibited the best substrate activity [90% yield of 2-chloroadenosine (8) in 30 min], D-arabinose reached an equilibrium at a concentration of ca. 1:1 of a starting base and the formed 2-chloro-9-(β-D-arabinofuranosyl)adenine (6) in 45 min, the formation of 2-chloro-9-(β-D-xylofuranosyl)adenine (7) proceeded very slowly attaining ca. 8% yield in 48 h.

Abstract
2,3-Dihydroxy-quinoxaline, a small molecule that promotes ATPase catalytic activity of Herpes Simplex Virus thymidine kinase (HSV-TK), was identified by virtual screening. This compound competitively inhibited HSV-TK catalyzed phosphorylation of acyclovir with Ki=250 μM (95% CI: 106-405 μM) and dose-dependently increased the rate of the ATP hydrolysis with KM=112 μM (95% CI: 28-195 μM). The kinetic scheme consistent with this experimental data is proposed.

Abstract
Pigment epithelium-derived factor (PEDF), a 50 kDa secreted glycoprotein, is among the most potent endogenous inhibitors of angiogenesis. PEDF-derived fragment (44-77) possesses antiangiogenic properties of the full-sized protein and is a potential drug candidate for the treatment of ocular neovascular diseases. In this study we propose an efficient scalable biotechnological method for the production of PEDF (44-77) as part of a fusion protein with SspDnaB intein. The fusion protein was obtained in bacterial E. coli cells in the form of inclusion bodies, solubilized and subjected to autocatalytic cleavage with the release of PEDF (44-77) (yield, 77%). The target peptide was separated from the intein using tangential ultrafiltration. The final purification of PEDF (44-77) was performed by reversed-phase HPLC. The yield of the target peptide (purity, 99%) was 65 mg per 1 liter of culture. Antiangiogenic activity of the obtained peptide was studied in vitro using murine endothelial cells SVEC-4-10. PEDF (44-77) suppressed proliferation of endothelial cells by 53% and inhibited endothelial cell tube formation at the concentration of 1 nM. The ability of the recombinant PEDF (44-77) to block initial stages of angiogenesis was demonstrated using the model of rabbit corneal neovascularization.

Abstract
Hirudin-1 is a highly selective inhibitor of thrombin secreted by salivary glands of the medicinal leech Hirudo medicinalis. This direct anticoagulant is used for the treatment and prevention of disorders in blood coagulation system. Apart from the existing recombinant analog of hirudin-1 (63-desulfatohirudin-1, desirudin) its modified analogs possessing higher activity and stability are of medical value. In this study artificial genes of hirudin and two its analogs (hirudin-1, [Leu1, Thr2]-hirudin-1 and [Leu1, Thr2]-hirudin-1/3) were synthesized and cloned in an expression vector pTWIN1 in frame with the gene of mini-intein SspDnaB from Synechocystis sp. Producing strains of the corresponding fusion proteins were constructed using E. coli strain ER2566. Biotechnological schemes for the production of 63-desulfatohirudin-1 and its analogs were developed. The scheme includes the following stages: isolation of the fusion protein after the desintegration of the cell biomass, refolding of the target peptide within the fusion protein, pH-inducible cleavage of the fusion protein, and chromatographic purification of the target product. Antithrombotic activity of the obtained peptides was determined by a standard amidolytic assay. The developed methods for the production of 63-desulfatohirudin-1, [Leu1, Thr2]-desulfatohirudin-1 [Leu1, Thr2]-desulfatohirudin-1/3 allowed to obtain these peptides with high yields (14, 25 and 24 mg per liter of cell culture respectively) and high activity (13423, 33333 and 19802 ATU/mg respectively).

Abstract
An artificial gene consisting of seven copies of an oxytocinoyl-lysine encoding sequence arranged in a tandem was synthesized and inserted downstream of the SspDnaB intein gene in a pTWIN1 plasmid. The corresponding fusion protein Dnab-7oxy contained 16 cysteine residues and formed inclusion bodies when expressed in E. coli. The standard protocol involving solubilization of the fusion protein and its autocatalytic cleavage on a chitin resin was not effective because of a very low yield of the cleavage reaction. Attempts to perform a refolding of the intein part of the fusion protein in solution were also unsuccessful because of a high level of protein aggregation. Sulfitolysis of cysteine residues is known to increase a solubility of proteins and peptides. Therefore we suggested a one-step approach that combines solubilization of inclusion bodies and sulfitolysis of a hybrid protein. The fusion protein was completely reduced and solubilized in 8M urea at pH 9.0 in the presence of sodium sulfite and sodium tetrathionate. The sulfitized protein was loaded onto a chitin column, an efficient cleavage was induced by a pH shift from 9.0 to 6.5, and seven successively connected oxytocinoyl- lysine units were released. The heptamer was subjected to trypsinolysis yielding sulfitized monomers of oxytocinoyllysine. Oxytocinoyl-lysine was refolded as described previously and treated by carboxypeptidase B to form the oxytocinic acid. The target oxytocin amide was then synthesized via methyl ester intermediate. Using this approach 6 mg of recombinant oxytocin can be obtained from 1 g of biomass.

Abstract
Thymosin beta4 (43 aa) is a highly conserved acidic peptide which regulates actin polymerization in mammalian cells by sequestering globular actin. Thymosin beta4 is undergoing clinical trials as a drug for the treatment of venous stasis ulcers, corneal wounds and injuries, as well as acute myocardial infarction. Currently, thymosin beta4 is produced with solid-phase chemical synthesis. Biotechnological synthesis of this peptide presents difficulties because N-terminal amino acid residue of thymosin beta4 is acetylated. In this study we propose a method for producing the recombinant precursor of thymosin beta4 and its subsequent targeted chemical acetylation. Desacetylthymosin beta4 was synthesized as a part of a hybrid protein with thioredoxin and a specific TEV (tobacco etch virus) protease cleavage site. The following scheme was developed for the purification of desacetylthymosin beta4: (i) the biosynthesis of a soluble hybrid protein (HP) in Escherichia coli; (ii) isolation of the HP by ion exchange chromatography; (iii) cleavage of the HP with TEVprotease; (iv) purification of desacetylthymosin beta4 by ultra-filtration. N-terminal acetylation of desacetylthymosin beta4 was performed with acetic anhydride under acidic conditions (pH 3). The reaction yield was 55%. Thymosin beta4 was then purified by reverse-phase high performance liquid chromatography. The proposed synthetic approach to recombinant thymosin beta4 is suitable for scale-up and can provide for the medical use of highly purified preparation with a yield of 20 mg from 1 L of culture.

Abstract
The cointegration rate into the aspen and birch genomes of foreign genes from a binary vector and a disarmed Ti plasmid pCBE21 carried by the same Agrobacterium tumefaciens strain was studied. The cotransformation rate for the genes within the Ti plasmid varied from 30 to 100%; while the transformation rate for the gene from T(L) region was twofold higher as compared with the T(R) region. On the average, the gene transfer from all three T-DNAs was recorded in 10.9% of the transgenic lines. For the vector pBI121, the cotransformation rates for the genes from both regions of pCBE21 T-DNA were higher as compared with the vector pGS. In addition, a concurrent transfer of the genes from the Ti plasmid T(L) and T(R) regions was recorded only after the transformation with the vector pBI121. These results can be used for constructing woody plants containing several genes.

Abstract
The ability of water preparations of different composition to affect the generation of superoxide radicals has been compared. The superoxygenating reaction of adrenaline autoxidation with some modifications was used as a model system, which makes it possible to reveal the pro/antioxidant properties of materials being tested. It was shown that samples of water from sources having different specific electroconductivity and, accordingly, ionic composition differ in the ability to affect reactions proceeding with the participation of ROS. The parameter measured, the pro/antioxidant activity of water, is a new informative indicator, and the approach proposed enables one to perform a comparative estimation of the quality of water and aqueous solutions.

Abstract
Natural and modified purine nucleosides have been synthesized using the recombinant thermostable enzymes purine nucleoside phosphorylase II (EC 2.4.2.1) and pyrimidine nucleoside phosphorylase (EC 2.4.2.2) from Geobacillus stearothermophilus B-2194. The enzymes were produced in recombinant E. coli strains and covalently immobilized on aminopropylsilochrom AP-CPG-170 after heating the cell lysates and the removal of coagulated thermolabile proteins. The resulting preparations of thermostable nucleoside phosphorylases retained a high activity after 20 reuses in nucleoside transglycosylation reactions at 70-75 degrees C with a yield of the target products as high as 96%. Owing to the high catalytic activity, thermal stability, the ease of application, and the possibility of repeated use, the immobilized preparations of thermostable nucleoside phosphorylases are suitable for the production of pharmacologically important natural and modified nucleosides.

Abstract
Bacteriophage T5 deoxynucleoside monophosphate kinase (dNMP kinase, EC 2.7.4.13) is shown to catalyze the phosphorylation of both d(2)CMP and ribonucleotides AMP, GMP, and CMP, but does not phosphorylate UMP. For natural acceptors of the phosphoryl group, K(m) and k(cat) were found. The applicability of T5 dNMP kinase as a universal enzyme capable of the phosphorylation of labelled r/dNMP was shown for the synthesis of [alpha-(32)P]rNTP and [alpha-(32)P]dNTP.

Abstract
The ability of Bacillus licheniformis strain VKM B-511 to grow and synthesize biosurfactants under both aerobic and anaerobic conditions has been demonstrated. Yields of biosurfactants, emulsion indices and surface tension were considerably higher in culture liquor and preparations derived from cultures grown anaerobically at a C/N ratio of 1 : 24, pH 7.0, and temperature of 30 degrees C. Biosurfactant production by B. lichenformis also depended on concentrations of NaCl and Na2S in the medium and on water characteristics, reaching 4.58 g/l for bacteria grown anaerobically on a medium containing anolyte fraction of water.

Abstract
An enzymatic transglycosylation of purine heterocyclic bases employing readily available natural nucleosides or sugar-modified nucleosides as donors of the pentofuranose fragment and recombinant nucleoside phosphorylases as biocatalysts has been investigated. An efficient enzymatic method is suggested for the synthesis of purine nucleosides containing diverse substituents at the C6 and C2 carbon atoms. The glycosylation of N(6)-benzoyladenine and N(2)-acetylguanine and its O(6)-derivatives is not accompanied by deacylation of bases.

Abstract
Cladribine (2-chloro-2'-deoxyadenosine) was synthesized using intact cells of the recombinant Escherichia coli strain producing Geobacillus stearothermophilus B-2194 thermostable purine-nucleoside phosphorylase II (EC 2.4.2.1). Use of the cells containing this thermostable enzyme allowed the process to be conducted at a temperature of 70 degrees C, which provided the maximal concentrations of sparingly soluble substrates. The best results were obtained with 2-chloroadenine as a modified base. The highest yield of the target 2-chloro-2'-deoxyadenosine (up to 95% in the case of deoxyguanosine) was reached when using 2'-deoxypurines as donors of deoxyribose. Use of thymidine for these purposes required its considerable molar excess over 2-chloroadenine (up to 6 : 1), which is connected with a nonoptimal amount of endogenous thymidine phosphorylase, necessary for synthesis of deoxyribose-1-phosphate, in the transglycosylation reaction.

Abstract
The development of modern pharmacology cannot be imagined without the use of genetic engineering methods (recombinant DNA technology). The success of medicine is increasingly based on the active use of protein preparations obtained using the technology of transferring hereditary information (genes) from one organism to another. The emergence of the ability to express foreign genes in the cells of various organisms (both eukaryotes and prokaryotes) has become one of the revolutionary events in the science of the last two decades of the 20th century and laid the foundations of modern biotechnology.

Abstract
The biological activity of the catholyte and anolyte of bidistilled water in experiments with the germination of wheat grains in the period from March to May has been studied. The activity of solutions, which was characterized by the grain germination index, was high at the beginning of the period, then it gradually decreased and was equal to zero at the middle of the period; at the end of the period it gradually increased almost to initial values. It has been established that the effectiveness of bidistilled water anolyte was as a rule higher than that of catholyte throughout the observation period. At the beginning and end, the stimulating effect of anolyte was 5-5.5 times greater than that of catholyte. The seasonal changes in the biological activity of M 9 medium catholyte were compared with those of bidistilled water anolyte and catholyte. The stimulating effect of M 9 catholyte was estimated by changes in the growth of E. coli cells. The stimulating effect, which was estimated from an increase in the optical density of cell suspension in the initial period at a cultivation temperature of 20 degrees C was 55-60% relative to control (untreated medium). Then it decreased almost to zero in the middle of the period to increase again approximately to the initial values. The assumption has been made that the physicochemical causes of the influence of catholyte and anolyte of bidistilled water on wheat grains and of the culture medium catholyte on E. coli cells are of different nature.

Abstract
Ribokinase (RK) was expressed in the Escherichia coli ER2566 cells harboring the constructed expression plasmid encompassing the rbsK gene, encoding ribokinase. The recombinant enzyme was purified from sonicated cells by double chromatography to afford a preparation that was ca. 90% pure and had specific activity of 75 micromol/min mg protein. Catalytic activity of RK: (i) is strongly dependent on the presence of monovalent cations (potassium>>>ammonium>cesium), and (ii) is cooperatively enhanced by divalent magnesium and manganese ions. Besides D-ribose and 2-deoxy-D-ribose, RK was found to catalyze the 5-O-phosphorylation of D-arabinose, D-xylose, and D-fructose in the presence of ATP, and potassium and magnesium ions; L-ribose and L-arabinose are not substrates for the recombinant enzyme. A new radiochemical method for monitoring the formation of D-pentofuranose-5-[32P]phosphates in the presence of [gamma-32P]ATP and RK is reported.

Abstract
The short-wave fluorescence of bidistilled water treated in the cathode and anode chambers of two types of electrolysers made from different materials was investigated by fluorescence spectroscopy. It was shown that the electrochemical treatment of water did not induce intrinsic short-wave flyorescence of catholyte and anolyte in the case of quartz glass electrolyser. The increase observed in the intensity of intrinsic short-wavelength fluorescence of bidistilled water in the catholyte and anolyte of the electrolyser made from technical organic glass was caused by microcontaminations released from electrolyser material in the samples.

Abstract
Galectins, beta-galactoside binding proteins, expressed selectively in human breast carcinoma are attractive targets to employ lectin-aimed therapeutics. We examined beta-galactoside binding potency of neoplastic cells using fluorescein-labelled synthetic glycoconjugates as probes for flow cytometry. As a result, surface beta-galactoside binding proteins/galectins were discovered on mouse mammary carcinoma cells in vitro and in vivo unlike non-malignant cells from the several tissues; and asialo-GM1 ganglioside carbohydrate part--containing probe was the most specific one. However, in liver and lung metastatic cells galectins seem to be expressed within cytoplasm and/or nuclei. Galectin expression correlated directly with aggressive tumour potential in the A/Sn transplantable model similar to findings in several human breast carcinoma cell lines. However, galectin expression was reduced during tumour progression in more aggressive forms of spontaneous BLRB mammary carcinomas like it was shown for human breast carcinoma specimens. Analysis of the histopathological data led, however, to the conclusion that galectin expression hardly might be a suitable marker of aggressiveness of heterogeneous mammary carcinomas as the observed level of galectin expression is influenced by the amount of the stroma in a tumour sample and/or probably, galectin expression inversely correlates with tumour aggressiveness during the initial and advanced steps of mammary tumour progression. We conclude that surface beta-galactoside binding proteins/galectins that are selectively expressed during mouse mammary carcinoma progression, similarly to human breast carcinomas, seem to be proper targets for asialo-GM1-vectored cytotoxics and our mouse model system might be a relevant instrument to further test novel modes of anti-breast cancer therapy.

Abstract
A semiquantitative assay of DNA impurities in preparations of human recombinant insulin is described. The assay is based on the detection of a fragment of the ampicillin-resistant gene within the producer strain DNA by PCR. The analysis of PCR products of the studied preparations and PCR products containing known amounts of E. coli total DNA enabled a quantitative determination of the producer strain DNA content in the preparations under study. The sensitivity of the method is 7 pg of E. coli DNA per 10 microg of human recombinant insulin. The high sensitivity of the method allows us to recommend it for the quantitative determination of DNA content in recombinant preparations that do not inhibit PCR.

Abstract
The biotechnological method of synthesis of ribavirin, vidarabin, and 6-azauridine by the use of immobilized recombinant enzymatic preparations of nucleoside phosphorylase was improved. The effect of ribavirin and its combinations with the other synthesized nucleosides on the reproduction of Vaccinia virus was studied using cultures of Vero cells. The combination of ribavirin and vidarabin was shown to provide an antiviral effect at lesser concentrations than when these compounds were taken separately.

Abstract
4-Thiouridine and 4-thiothymidine were developed as efficient substrates for spectrophotometric determination of uridine phosphorylase and thymidine phosphorylase activity. 4-Thiouridine has maximum absorbance at 330 nm (pH 7.5). The change in extinction coefficient for 4-thiouridine/4-thiouracil, deltaepsilon is 3000 M(-1) x cm(-1). It appeared that 4-thiouridine is a good substrate for uridine phosphorylase with Michaelis-Menten constant 130 microM and kcat 49 s(-1). In the case of 4-thiothymidine/4-thiothymine deltaepsilon is even larger: 5000 M(-1) x cm(-1) at 336 nm.

Abstract
To study the causes of the biological effect of electrochemically activated solutions, nutrient growth media M 9 were prepared using catholyte and anolyte solutions containing separate components of the nutrient medium, such as distilled water, phosphate buffer, phosphate buffer with chlorides (NaCl, NH4Cl), and chlorides. The biological activity of different nutrient media was assessed by a comparison with the stimulation or inhibition of the growth of Escherichia coli cells in the catholyte and anolyte of the complete nutrient medium M 9. It was shown that medium M 9 prepared on the catholytes of different initial solutions acquired the stimulating properties only if the initial solution contained salts containing chlorine. The stimulating effect of the initial solution was 18-24%. Electrochemical treatment of solutions containing no chlorides (distilled water, phosphate buffer) and subsequent addition of the components of nutrient medium to exposed solutions had neither a stimulating nor the inhibiting effect on cell growth. The cultivation of cells in a nutrient medium based on the catholyte of preliminarily treated hydrochloric acid showed that it is the presence of chlorine ions in solution during electrolysis that causes the stimulating effect of the nutrient medium based on the catholyte. The formation of oxidizers and the inhibitory effect of the anolyte described previously was also observed if the solution contained chlorine ions during electrolysis. Possible mechanisms of the biological effect of catholytes containing chlorides during electrolysis were discussed.

Abstract
An artificial gene encoding thymosin alpha1 was obtained by the chemoenzymatic synthesis and cloned into Escherichia coli. An expressing recombinant plasmid containing the hybrid protein gene, which encodes amino acid sequences of thymosin alpha1 and the Saccharomyces cerevisiae intein Sce VMA, was constructed. The expression of the hybrid protein from the resulting hybrid gene in E. coli, the properties of the resulting hybrid protein, and the conditions for its nonenzymatic cleavage to thymosin alpha1 were studied.

Abstract
The formation of hydrogen peroxide in catholytes and anolytes of electrochemically activated solutions: bidistilled water and solutions of sodium chloride and nutrition medium M9 was studied. The concentration of hydrogen peroxide was determined by the method of enhanced chemiluminescence in a system peroxidase-luminol-p-iodophenol. It was shown that the concentration of hydrogen peroxide depends on the ionic content of the solution and varies from a few fractions of a micromole in catholytes of bidistilled water and sodium chloride solutions (10(-5) divided by 10(-2) M) to 20-25 microM in catholytes of medium M9. The concentration of H2O2 in anolytes of various solutions was 15-20 times lower than in the corresponding catholytes and was equal to a few nanomoles in bidistilled water and a few micromoles in medium M9. The biological activity of the catholyte of medium M9 was determined from changes in the growth of E. coli cells. It was found that this catholyte stimulates the cell growth. The stimulating effect was 20-25% and did not change after the decomposition of hydrogen peroxide in the catholyte by catalase. The addition of H2O2 at the corresponding concentration to the inactivated nutrient medium produced no stimulating effect. These data suggest that hydrogen peroxide formed in the catholyte of nutrient medium M9 does not affect its biological activity.

Abstract
The plasmid DNA pERilox4 containing the gene of the recombinant protein, which included the leader sequence and the oxytocinoyl lysine tetramer, was constructed. The high level of gene expression in E. coli was achieved. The method for purification of the recombinant protein and its isolation in the soluble form was developed. The conditions for digestion of the hybrid protein by trypsin and carboxypeptidase B were matched. The effective method for transformation of oxytocinic acid to oxytocin was worked out. The scheme suggested allowed obtaining oxytocin in high yield.

Abstract
Interleukin-2 therapy is not clearly effective against breast cancer both in mouse models and in human patients. However, the study of IL-2 therapy of breast cancer remains important, as 3,700 women died from this malignancy in the Netherlands in 2000. Previously we have shown the therapeutical efficacy of a single peritumoural IL-2 application in different experimental models and in veterinary patients. Here we apply this mode of IL-2 therapy to advanced mouse mammary carcinoma models, i.e., severe metastasised tumours in A/Sn mice and non-metastasised carcinomas in BALB/c mice. Mice with advanced transplanted mammary carcinomas were given a single peritumoural treatment with 2.5 x 10(6) IU IL-2 at days 10-14 after i.p. or s.c. inoculation of 10(6) carcinoma cells. Within each experiment it was always possible to distinguish relatively slowly and fast growing tumours which allows the therapeutical effect of IL-2 in tumours with different growth rates to be studied. A new approach to analyse results enabled us to show that survival of mice with transplanted, advanced metastasised breast cancer can be significantly improved after a single local treatment with IL-2. Advanced relatively fast i.p and s.c. growing mammary carcinomas seem to be more sensitive to a single IL-2 treatment than relatively slowly growing tumours. IL-2 was most effective against non-metastasised mouse breast cancer.

Abstract
A new approach to enhanced specificity and product yield of polymerase chain reaction is proposed. It is based on control of DNA polymerase activity during PCR by changing the magnesium ion concentration, which depends on the temperature of the reaction mixture. A slightly soluble magnesium salt, magnesium oxalate, whose solubility depends on temperature, was used as a source of magnesium ions. During PCR, magnesium oxalate was maintained at saturating concentration by the presence of an insoluble excess of this salt, and the concentration of magnesium ions depended on the salt solubility: binding of magnesium ions at lower temperatures and their release at higher temperatures was shown to affect the DNA polymerase activity and to favor the specific PCR amplification of the target DNA fragment.
