Characterization of a lectin from the leaves of great northern bean, Phaseolus vulgaris L.

A novel lectin (GNLL) was isolated from the leaves of the Great Northern bean, Phaseolus vulgaris. GNLL was purified by affinity chromatography on ovomucoid-Sepharose 4B. GNLL had a molecular mass of 135 kDa on gel filtration and gave two bands on SDS-polyacrylamide gel electrophoresis (PAGE)(band A of 34.0 kDa and band B of 34.2 kDa). Binding assay of horseradish peroxidase (HRP)-glycoproteins to the bands electroblotted onto polyvinylidene difluoride (PVDF) membrane showed that both bands could bind to complex-type N-linked oligosaccharide chains in glycoproteins. The N-terminal amino acid sequences of both bands were identical through the 10 residues and identical to that of alpha-subunit of a pod lectin (pod-alpha-subunit) from the same bean. On the other hand, band B cross-reacted with monoclonal antibody against a seed lectin from the same bean, but band A did not.

Supramolecular architecture of a copper(II) complex with lactato and 2,2?-dipyridylamine showing embedded water chains

A new mixed-ligand complex [CuL2(dipyam)]-3H2O (1) (L = lactato and dipyam = 2,2?-dipyridylamine) has been prepared and structurally characterized by X-ray diffraction. The presence of three crystallization water molecules creates several hydrogen-bonded networks. Two crystallographic unique crystallization water molecules are arranged into infinite one-dimensional chains embedded by additional hydrogen bonds between stacked complex double-chains, but the third crystallization water molecule is apart from the chain and acts as bridge to form centrosymmetric complex tetramers.

Synthesis, DNA binding profile and DNA cleavage pathway of divalent metal complexes

Complexes of dipyridylamine based ligand with an anthracene moiety containing divalent metal ions Co(ii), Cu(ii), Ni(ii), Zn(ii) and Cd(ii) were characterized structurally. The experimental results showed that they can induce considerable oxidative DNA cleavage in the presence of hydrogen peroxide and dioxygen. The Zn(ii) complex did not show any appreciable cleavage activity, whereas the Cd(ii) and Ni(ii) complexes were moderately active. On the other hand, Cu(ii) and Co(ii) complex showed the formation of a significant quantity of linear DNA resulting from the double-strand breaks. Mechanistic studies revealed the involvement of HO? and the superoxide anion to be the reactive species in the scission process in aerobic media. A mechanism involving either the Fenton or the Haber-Weiss reaction was proposed for the DNA cleavage mediated by these complexes. The Cu(ii) complex could also cleave the double stranded calf thymus DNA (ds DNA) in the presence of activators, most likely via an oxidative mechanism, whereas the activity of the other complexes was negligible under similar reaction conditions. The kinetic aspects of ds DNA cleavage with the Cu(ii) are detailed. The interaction of the five metal complexes with ds DNA was investigated by UV absorption and linear dichroism studies, and the mode of complexes binding to ds DNA is proposed.

Electrochemical O-glycosylation using thioglycosides as glycosyl donors in the presence of a catalytic amount of sodium trifluoromethanesulfonate as a supporting electrolyte

Electrochemical O-glycosylation of primary alcohols with O-protected thioglycosides was performed in the presence of a small amount of sodium trifluoromethansulfonate (12.5 mol % to glycosyl acceptor) as a supporting electrolyte. The reaction was successfully carried out in an undivided cell to give O-glycosides in good yields with a high electro-efficiency (ca. 1 F/mol) at 15 C in acetonitrile.

Synthesis, characterization, mixed-ligand complex formation reactions, and equilibrium studies of Co(II) with 2,2?-dipyridylamine and some selected biorelevant ligands

Binary and ternary cobalt(II) complexes involving 2,2?-dipyridylamine and various biologically relevant ligands containing different functional groups are investigated. The ligands used are dicarboxylic acids, amino acids, and DNA unit constituents. The ternary complexes are formed by simultaneous reactions. The results showed the formation of 1:1 complexes with amino acids and dicarboxylic acids. The effect of chelate ring size of the dicarboxylic acid complexes on their stability constants was examined. The stability of ternary complexes formed with dicarboxylic acids was quantitatively compared with their corresponding binary complexes in terms of the a?log 10 K parameters. The concentration distribution of the complexes in solution was evaluated. The solid complexes of Co(II) dipyridylamine cyclobutane-1,1-dicarboxylate, or malonate, oxalate, and succinate have been synthesized and characterized by elemental analysis, infrared spectra, magnetic, and conductance measurements. Spectroscopic studies and M eff values suggest a tetrahedral geometry for the cobalt(II) complexes. The effect of temperature on the formation constant of the complexes was studied, and the thermodynamic parameters were calculated. Formation of the metal complexes has been found to be spontaneous, exothermic, and entropically favorable.
