Acascade synthesis protocol for glycosides of 1,4-butanediol monomesylate, as anticancer drug candidates, is proposed. All obtained compounds are characterized by FT-IR, 1H and 13C NMR spectroscopy technique after separation by column chromatog. Cytotoxicity of the obtained glucosides and galactosides of 1,4-butanediol monomesylate on K562 human erythroleukemia cell line and normal peripheral blood mononuclear cells (PBMCs) is also investigated. Compared to the commerical anticancer drugs such as busulfan and doxorubicin, these compounds indicate promising results against the test cells. It is suggested that these new anticancer agents can be a potential replacement for the current drugs since they have relatively convenient synthetic procedure and higher effectiveness.

Fukutani, Tomonori; Miyazawa, Kohei; Iwata, Satoru; Satoh, Hiroko published the artcile< G-RMSD: Root Mean Square Deviation Based Method for Three-Dimensional Molecular Similarity Determination>, Quality Control of 492-62-6, the main research area is GRMSD Generalized Root Mean Square Deviation mol similarity determination.

We present the Generalized Root Mean Square Deviation (G-RMSD) method. G-RMSD is an optimization method to calculate the minimal RMSD value of two at. structures by optimal superimposition. G-RMSD is not restricted to systems with an equal number of atoms to compare or a unique atom mapping between two mols. The method can handle any type of chem. structure, including transition states and structures which cannot be explained only with valence bond (VB) theory (non-VB structures). It requires only Cartesian coordinates for the structures. Further information, i.e. atom- and bond types can also be included. Applications of G-RMSD to the classification of α-d-glucose conformers and 3D partial structure search using a dataset containing equilibrium (EQ), dissociation channel (DC), and transition state (TS) structures are demonstrated. We find that G-RMSD allows for a successful classification and mapping for a wide variety of mol. structures.

Lian, Shengyang; Fan, Shuling; Yang, Ying; Yu, Bin; Dai, Chunxiao; Qu, Yuanyuan published the artcile< Selenium nanoparticles with photocatalytic properties synthesized by residual activated sludge>, Computed Properties of 492-62-6, the main research area is dye selenite selenium nanoparticle photocatalyst activated sludge wastewater treatment; Activated sludge; Biosynthesis; Photocatalysis; Rhodamine B; Selenium nanoparticles.

The treatment and disposal of residual activated sludge is a worldwide problem and the research on its reuse is still only in the earliest stages. Selenite is a toxic pollutant, while selenium nanoparticles (SeNPs) are environmentally friendly and have promising application prospects. At present, the reduction mechanism of selenite under the complex system is still poorly understood. In order to explore the mechanism of SeNPs synthesis by activated sludge resource utilization, SeNPs were synthesized by activated sludge extracts of domestic sewage (DSeNPs) and coking sewage (CSeNPs), resp. The synthesis process, zeta potential and morphol. size of SeNPs were changed by pH value, extract concentration and extract composition Under the same synthesis conditions, the morphologies of DSeNPs and CSeNPs were mainly spherical and pseudo-spherical, while CSeNPs also contained pseudo-rod shape particles. The sizes and crystal grains of CSeNPs were smaller than those of DSeNPs. Compared with DSeNPs, a specific protein (∼35 kDa) was found on the surface of CSeNPs using SDS-PAGE. By analyzing the fluorescence images of the two SeNPs, it was found that the relative contents of proteins, α-D-glucopyranose polysaccharides, and β-D-glucopyranose polysaccharides on their surfaces were obviously different (P < 0.05). The present study demonstrated that proteins, polysaccharides, humic-like and fulvic acid-like substances cooperated in the formation and stabilization of SeNPs. Furthermore, CSeNPs (bandgap: 1.68 eV) had more desirable photocatalytic performance than DSeNPs (bandgap: 1.84 eV). Under the light condition, CSeNPs could degrade Rhodamine B faster without adding hydrogen peroxide. This experiment provided a new insight into the resource utilization of activated sludge and a reference for the synthesis of nanometer selenium with excellent performance.

Stankovic, Ivana M.; Blagojevic Filipovic, Jelena P.; Zaric, Snezana D. published the artcile< Carbohydrate - Protein aromatic ring interactions beyond CH/π interactions: A Protein Data Bank survey and quantum chemical calculations>, Name: (2S,3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol, the main research area is glucose carbohydrate protein aromatic ring interaction quantum chem method; Aromatic amino acids; CH/π interactions; Carbohydrates; Stacking interactions.

The geometries of the contacts between monosaccharides and aromatic rings of amino acids found in X-ray crystallog. structures, in the Protein Data Bank (PDB), were analyzed, while the energies of the interactions were calculated using quantum chem. method. We found 1913 sugar/aromatic ring contacts, 1054 of them (55%) with CH/π interactions and 859 of them (45%) without CH/π interactions. We showed that only the carbohydrate/aromatic contacts with CH/π interactions are preferentially parallel and enable sliding in the plane parallel to aromatic ring. The calculated interaction energies in systems with CH/π interactions are in the range from -1.7 kcal/mol to -6.8 kcal/mol, while in the systems without CH/π interactions are in the range -0.2 to -3.2 kcal/mol. Hence, the binding that does not include CH/π interactions, can also be important for aromatic amino acid and carbohydrate binding processes, since some of these interactions can be as strong as the CH/π interactions. At the same time, these interactions can be weak enough to enable releasing of small carbohydrate fragments after the enzymic reaction. The anal. of the protein-substrate patterns showed that every second or third carbohydrate unit in long substrates stacks with protein aromatic amino acids.

Alonso-Gil, Santiago published the artcile< MonteCarbo : A software to generate and dock multifunctionalized ring molecules>, SDS of cas: 492-62-6, the main research area is software multifunctionalized ring active site glycosidase; Monte Carlo; carbohydrates; conformations; docking; drug design.

MonteCarbo is an open-source software to construct simple 5-, 6-, and 7-membered ring multifunctionalized monosaccharides and nucleobases and dock them into the active site of carbohydrate-active enzymes. The core bash script executes simple orders to generate the Z-matrix of the neutral mol. of interest. After that, a Fortran90 code based on a pseudo-random number generator (Monte Carlo method) is executed to assign dihedral angles to the different rotamers present in the structure (ring and rotating functional groups). The program also has a generalized internal coordinates (GIC) implementation of the Cremer and Pople puckering coordinates ring. Once the structures are generated and optimized, a second code is ready to execute in serial the docking of multiple conformers in the active site of a wide family of enzymes.

Wheatley, David E.; Fontenelle, Clement Q.; Kuppala, Ramakrishna; Szpera, Robert; Briggs, Edward L.; Vendeville, Jean-Baptiste; Wells, Neil J.; Light, Mark E.; Linclau, Bruno published the artcile< Synthesis and Structural Characteristics of all Mono- and Difluorinated 4,6-Dideoxy-D-xylo-hexopyranoses>, Category: alcohols-buliding-blocks, the main research area is monosaccharide crystal structure free energy human deoxygenation deoxyfluorination; crystal structure free energy deoxyxylohexopyranose glycoside preparation protecting group.

Here, we report a detailed study on the synthesis of monosaccharides in which the hydroxy groups at their 4- and 6-positions are replaced by all possible mono- and difluorinated motifs. Minimization of protecting group use was a key aim. It was found that introducing electroneg. substituents, either as protecting groups or as deoxygenation intermediates, was generally beneficial for increasing deoxyfluorination yields. A detailed structural study of this set of analogs demonstrated that dideoxygenation/fluorination at the 4,6-positions caused very little distortion both in the solid state and in aqueous solution Unexpected trends in α/β anomeric ratios were identified. Increasing fluorine content always increased the α/β ratio, with very little difference between regio- or stereoisomers, except when 4,6-difluorinated.

Meng, Zhiyuan; Tian, Sinuo; Sun, Wei; Liu, Li; Yan, Sen; Huang, Shiran; Zhu, Wentao; Zhou, Zhiqiang published the artcile< Effects of exposure to prothioconazole and its metabolite prothioconazole-desthio on oxidative stress and metabolic profiles of liver and kidney tissues in male mice>, Related Products of 492-62-6, the main research area is prothioonazole fungiide metabolic disorder oxidative stress kidney; Metabolic profile; Oxidative stress; Prothioconazole; Prothioconazole-desthio.

Prothioconazole (PTC), a popular agricultural fungicide, and its main metabolite prothioconazole-desthio (PTCd) are receiving great attention due to their toxicol. effects in the non-target organisms. This study investigated their dosage-dependent (1 and 5 mg/kg BW/day) toxicol. effects on oxidative stress and metabolic profiles of liver and kidney tissues using male mice. PTC and PTCd significantly inhibited the growth phenotype including body weights gain, liver and kidney indexes. Furthermore, these effects were deeply investigated using the biomarkers of oxidative stress, and metabolomics. Notably, these effects were dose and tissue-dependent. Specifically, the more serious impacts involving oxidative stress and metabolic disorders were observed in the high concentration treatment groups. Also, the liver tissue was more severely affected than the kidney tissue. Lastly, the change in oxidative stress biomarkers and metabolomics profile revealed that PTCd induced more severe toxic effects than the parent compound PTC. In brief, these results indicate that exposure to PTC and PTCd could cause potential health risks in mammals.

Wang, Yongqiang; Xie, Hongbing; Liu, Dongyang; Wang, Yimin; Liu, Changzhong; Khan, Muhammad Akram; Jiang, Jinqing; Zhang, Wenjv published the artcile< Effects of Different Sample Pulverisation Methods on the Extraction of Metabolites from the Fermented Cottonseed Meal Based on UPLC-Q-TOF-MS>, Name: (2S,3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol, the main research area is Lactobacillus cottonseed meal fermented feed pulverization food processing UPLC.

Abstract: The precondition of studying biol. sample is to extract sample metabolites by the best pretreatment methods. There is already limited information about pretreatments of fermented feed metabolites. The study compared the extraction effects of different pulverisation methods used in the sample pretreatment process for the extraction of metabolites from cottonseed meal fermented by Lactobacillus acidophilus based on UPLC-Q-TOF-MS. The extraction effects of three pretreatments (non-pulverisation (WF), pulverisation (F), and high-speed homogenisation methods (YJ)) were compared with the numbers of metabolites and the normalized peak areas of the metabolites. The results showed that the number of metabolites extracted with three pulverisation methods were 1745, 1896, 2132 (ESI+ mode) and 1447, 1675, 2073 (ESI- mode), resp. The number of variable importance plot (VIP) metabolites and the relative peak areas of metabolites showed that the trend was YJ > F > WF. The extraction effect of high-speed homogenisation method was the best way to extract metabolites from the fermented cottonseed meal. This study built a foundation work for the further research of the fermented feed metabolomics.

Wang, Changchen; Wang, Hongquan; Bo, Zhao; Xia, Leilei; Jiang, Haiyue; Bo, Pan published the artcile< The characterization, cytotoxicity, macrophage response and tissue regeneration of decellularized cartilage in costal cartilage defects>, Electric Literature of 492-62-6, the main research area is decellularized cartilage tissue regeneration cytotoxicity macrophage response; Costal cartilage defect; Decellularized cartilage; Macrophage response; Thoracic deformity.

After harvesting multiple costal cartilages, the local defect disrupts the integrity of the chest wall and may lead to obvious thoracic complications, such as local depression and asymmetry of the bilateral thoracic height. Decellularized materials have been used for tissue reconstruction in clin. surgeries. To apply xenogenic decellularized cartilage in costal cartilage defects, porcine-derived auricular and costal cartilage was tested for characterization, cytotoxicity, macrophage response, and tissue regeneration. Most of the DNA and α-Gal were effectively removed, and the collagen was well preserved after the decellularization process. The glycosaminoglycan (GAG) content decreased significantly compared to that in untreated cartilage. The decellularized auricular cartilage had a larger pore size, more pores, and a higher degradation rate than the decellularized costal cartilage. No apparent nuclei or structural damage was observed in the extracellular matrix. The decellularized auricular cartilage had a higher cell proliferation rate and more prominent immunomodulatory effect than the other groups. Two types of decellularized cartilage, particularly decellularized auricular cartilage, promoted the tissue regeneration in the cartilage defect area, combined with noticeable cartilage morphol. and increased chondrogenic gene expression. In our research, the functional components and structure of the extracellular matrix were well preserved after the decellularization process. The decellularized cartilage had better biocompatibility and suitable microenvironment for tissue regeneration in the defect area, suggesting its potential application in cartilage repair during the surgery. Autologous costal cartilage has been widely used in various surgeries, while the cartilage defects after the harvesting of multiple costal cartilages may cause localized chest wall deformities. Decellularized cartilage is an ideal material that could be produced in the factory and applied in surgeries. In this study, both decellularized costal cartilage and auricular cartilage preserved original structure, functional biocompatibility, immunosuppressive effects, and promoted tissue regeneration in the cartilage defect area.

Wen, Jiawei; Wu, Jie; Yu, Haiqing; Fan, Gang; He, Yang published the artcile< Correlation analysis between genetic and chemical differences of Nardostachys jatamansi from different habitats in Ganzi Tibetan Autonomous Prefecture, Sichuan Province, China>, Electric Literature of 492-62-6, the main research area is nardostachys jatamansi metabolite marker extract phylogenetic mol evolution.

In the traditional Tibetan medicinal system, the medicinal parts of Nardostachys jatamansi (D.Don) DC. include the dried roots and rhizomes, which is effective in treating various diseases. In this study, mol. evolutionary anal. based on three markers (i.e., ITS, matK and rbcL), and principal component anal. combined with 1H NMR measurements were used to assess the genetic and chem. differences of the N. jatamansi from different habitats in Ganzi Tibetan Autonomous Prefecture, Sichuan Province, China. The results showed that the ITS marker was highly effective to identify the intraspecific variation of N. jatamansi. Furthermore, the results of the chem. anal. indicated that the nardosinone and sucrose, as the metabolite landmarks, can distinguish the different habitats of N. jatamansi in Ganzi Tibetan Autonomous Prefecture, Sichuan Province, China. Moreover, combining the chem. anal. with phylogenetic anal., the results indicated that the metabolites differences may be affected not only by genetic structures but also by environmental factors. These findings provide valuable references for the effective protection and exploitation of N. jatamansi resources.
