The chemical synthesis of pyridoxine-5?-beta-D-glucoside (5?-beta-PNG) was investigated using various glucoside donors and promoters. Hereby, the combination of alpha4,3-O-isopropylidene pyridoxine, glucose vested with different leaving and protecting groups and the application of stoichiometric amounts of different promoters was examined with regards to the preparation of the twofold protected PNG. Best results were obtained with 2,3,4,6-tetra-O-acetyl-D-glucopyranosyl fluoride and boron trifluoride etherate (2.0 eq.) as promoter at 0 C (59%). The deprotection was accomplished stepwise with potassium/sodium hydroxide in acetonitrile/water followed by acid hydrolysis with formic acid resulting in the chemical synthesis of 5?-beta-PNG.

Application of 10343-06-3, Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.10343-06-3, Name is 2,3,4,6-Tetra-o-acetyl-D-glucopyranose, molecular formula is C14H20O10. In a patent, introducing its new discovery.

A catalytic method is developed for the diastereoselective acylation of the anomeric hydroxyl group in diverse carbohydrates to form either alpha- or beta-anomeric esters. While exclusive formation of the beta-isomer was observed in most sugar substrates with one enantiomer of the chiral catalyst, moderate to high alpha-selectivity was obtained by using the other enantiomer of the chiral catalyst. The resulting alpha- and beta-anomeric esters have very different reactivity toward a reduction reaction.

Complex 1 was characterized using single-crystal X-ray diffraction analysis and found to be monomeric in nature with distorted square pyramidal geometry. The binding interactions of 1?6 with calf thymus DNA were studied using UV?visible absorption and emission spectroscopy and viscosity measurements. The DNA cleavage ability of 1?6 with pUC19 DNA shows that the complexes can cleave DNA without any external agents. The ligand and complexes were investigated for their in vitro antibacterial activity against Bacillus subtilis and Staphylococcus aureus. The complexes showed enhanced antibacterial activities compared to the free ligand. Molecular docking studies of complexes 1?6 were made using Genetic Optimization of Ligand Docking (GOLD) software. The study indicated that LEU23, ASP25, ILE84, ASN144 and ARG87 of COX-2 were important for strong hydrogen bonding interaction with the complexes. Among the complexes, 2 showed the best docking result with COX-2. Cytotoxicity assay was performed using MTT reagent against human cervical cancer cells, human breast cancer cells and human lung cancer cells. The complexes were found to show moderate anticancer activity.

A document type is Article, introducing its new discovery.

A series of dihydroartemisinin derivatives containing a sugar moiety was prepared in the search for analogues with good water solubility and high antimalarial activity. The preparation of the new compounds were achieved by treatment of dihydroartemisinin (2) with chlorotrimethylsilane in pyridine solution at -10 C to give a nearly quantitative yield of 10-O- (trimethylsilyl)dihydroartemisinin (3), which was then condensed with 1- hydroxypolyacetylated sugars 5 to give dihydroartemisinin derivatives 7a-d. Deacetylation of intermediates 7 gave the desired sugar derivatives 8. The resulting derivatives, tested in vitro against Plasmodium falciparum, were found to be more effective against W-2 than D-6 clones and were not cross- resistant with existing antimalarials. Trimethylsilylated compound 3 is more effective than derivatives 7a-d, which possess activity comparable to or better than that of artemisinin itself. Deacetylated compounds 8a-d were substantially less active than 7 in both cell lines. In P. berghei-infected mice, 7a-c showed 5/5, 2/5, and 3/5 cures, respectively, at 320 mg/kg per day x 3, whereas 7d showed no activity at the same dosage. However, 7d did prolong the life span in 3/5 of the infected mice at 640 mg/kg per day x 3 dose level. Trimethylsilylated compound 3 was also the most effective among the compounds studied, with 5/5 cures at 80 mg/kg per day x 3. The deacetylated sugar derivatives 8a-d showed only slight in vivo antimalarial activity.

The presented work, submitted as a paper, deals with the substitution reactions of mononuclear and dinuclear platinum(II) complexes of di-2-pyridylaminodiaquaplatinum(II), (Pt1); di-2-pyridylaminomethylbenzenediaquaplatinum(II), (Pt2); 1,2-bis(di-2-pyridylaminomethyl)benzenetetraquaplatinum(II), (Pt3); 1,3-bis(di-2-pyridylamino-methyl)benzenetetraquaplatinum(II), (Pt4); and 1,4-bis(di-2-pyridylaminomethyl)-benzenetetraquaplatinum(II), (Pt5). These reactions were carried out on aqua complexes by three nucleophiles, viz., thiourea, N,N?-dimethylthiourea, and N,N,N?N?-tetramethylthiourea under pseudo?first-order conditions as a function of nucleophile concentration and temperature by stopped-flow and UV?visible spectrophotometric techniques. In addition, some DFT calculation was performed. The activation parameters support an associative substitution mechanism.
