In this study two new complexes [Cu(bpy)(Gly)Cl]·2H2O (1) and [Cu(dpa)(Gly)Cl]·2H2O (2) (bpy = 2,2?-bipyridine; dpa = 2,2?-dipyridylamine, Gly = glycine) have been synthesized and characterized by elemental analysis, IR, TGA, UV-vis and magnetic susceptibility measurements. The binding properties of the complexes with CT-DNA were investigated by electronic absorption spectra. The intrinsic binding constants (Kb) calculated from UV-vis absorption studies were 1.84 × 103 M-1 and 3.1 × 103 M-1 for complexes 1 and 2 respectively. Thermal denaturation has been systematically studied by spectrophotometric method and the calculated DeltaTm was nearly 5 C for each complex. All the results suggest that the interaction modes between the complexes and CT-DNA were electrostatic and/or groove binding. The redox behavior of the two complexes was investigated by cyclic voltammetry. Both complexes, in presence and absence of CT-DNA show a quasi-reversible wave corresponding to CuII/CuI redox couple. The change in E1/2, DeltaE and Ipc/Ipa ascertain the interaction of complexes 1 and 2 with CT-DNA. Further insight into the binding of complexes with CT-DNA has been made by gel electrophoresis, where the binding of complexes is confirmed through decreasing the mobility and intensity of DNA bands. In addition, the antitumor activity of the complexes was tested on two cancer cell lines; the breast cancer (MCF7) and the human hepatocellular carcinoma (HEPG2), as well as one normal cell line; the human normal melanocytes (HFB4). The results showed that complex 1 was more potent antitumor agent than complex 2. The in-vitro antimicrobial activity of the two complexes was carried out using the disc diffusion method against different species of pathogenic bacteria and fungi. The activity data showed that complex 2 was more active in inhibiting the growth of the tested organisms.

Photorhabdus luminescens is known for its symbiosis with the entomopathogenic nematode Heterorhabditis bacteriophora and its pathogenicity toward insect larvae. A hypothetical protein from P. luminescens was identified, purified from the native source, and characterized as an L-fucose-binding lectin, named P. luminescens lectin (PLL). Glycan array and biochemical characterization data revealed PLL to be specific toward L-fucose and the disaccharide glycan 3,6-O-Me2-Glcbeta1-4(2,3-O-Me2)Rhaalpha-O-(p-C6H4)-OCH2CH2NH2. PLL was discovered to be a homotetramer with an intersubunit disulfide bridge. The crystal structures of native and recombinant PLL revealed a seven-bladed beta-propeller fold creating seven putative fucose-binding sites per monomer. The crystal structure of the recombinant PLL?L-fucose complex confirmed that at least three sites were fucose-binding. Moreover, the crystal structures indicated that some of the other sites are masked either by the tetrameric nature of the lectin or by incorporation of the C terminus of the lectin into one of these sites. PLL exhibited an ability to bind to insect hemocytes and the cuticular surface of a nematode, H. bacteriophora.

In a document type is Article, introducing its new discovery.

The crystal structure of Cs2[Co2(nta)2(mu-OH)2] · 4H2O (nta = nitrilotriacetate) has been determined from three-dimensional X-ray diffraction data. Two hydroxo groups act as bridging groups between the two Co metal centres. The Co – OH bond distances are 1.899(5) and 1.897(5) A, respectively and the Co – OH – Co bond angles 98.2(2). The nta ligand acts as a tetradentate ligand and bonds with a nitrogen as well as three oxygen atoms to the Co metal centre. The Co – N and Co – O(av) bonds are 1.922(6) and 1.895(5) A, respectively. (C10H10H3)2[CoCl4] consists of discrete monoprotonated 2,2?-iminodipyridinium cations and CoCl2-4 anions. The anions assume a regular tetrahedral geometry, with the Cl – Co – Cl bond angles varying between 107.34(10) and 112.07(10). The Co – Cl bond distances are 2.270(2) and 2.282(2) A, respectively. The two pyridine rings in the cation assume an almost planar orientation with a deviation of 7.7(6) for the dihedral angle between the two ring systems. The planar orientation can be attributed to weak hydrogen bonding between the unprotonated nitrogen atom of the one pyridine ring and the proton bonded to the other nitrogen atom on the adjacent ring.

Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. The appropriate choice can avoid electrode passivation, which strongly inhibit the efficient activation of substrates. 14215-68-0, Name is N-((2S,3R,4R,5R,6R)-2,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide, molecular formula is C8H15NO6. In a Article，once mentioned of 14215-68-0, category: Tetrahydropyrans

The substrate specificity of N-acetylhexosaminidase (E.C. 3.2.1.51) from Aspergillus oryzae was examined using p-nitrophenyl 6-O-sulfo-N-acetyl-beta-d-glucosaminide (6-O-sulfo-GlcNAc-O-pNP) as the glycosyl donor and a series of beta-d-glucopyranosides and N-acetyl-beta-d-glucosaminides with variable aglycons at the anomeric positions as the acceptors. When beta-d-glucopyranosides with methyl (CH3), allyl (CH2CH{double bond, long}CH2), and phenyl (C6H5) groups at the reducing end were used as the acceptors, this enzyme transferred the 6-O-sulfo-GlcNAc moiety in the donor to the location of O-4 in these glycosyl acceptors with a high regioselectivity, producing the corresponding 6-O-sulfo-N-acetylglucosaminyl beta-d-glucopyranosides. However, beta-d-glucopyranose lacking aglycon was a poor substrate for transglycosylation. This A. oryzae enzyme could also accept various N-acetyl-beta-d-glucosaminides carrying hydroxyl (OH), methyl (CH3), propyl (CH2CH2CH3), allyl (CH2CH{double bond, long}CH2) and p-nitrophenyl (pNP; C6H4-NO2) groups at their aglycons, yielding 6-O-sulfo-N-acetylglucosaminyl-beta(1?4)-disaccharide products.
