Manganese(II) complexes with the non-steroidal anti-inflammatory drug tolfenamic acid: Structure and biological perspectives

Manganese(II) complexes with the non-steroidal anti-inflammatory drug tolfenamic acid (Htolf) with the nitrogen-donor heterocyclic ligands 1,10-phenanthroline (phen), pyridine (py), or 2,2?-bipyridylamine (bipyam) and/or the oxygen-donor ligands H2O or N,N-dimethylformamide (DMF) have been synthesized and characterized. The crystal structures of complexes [Mn(tolf-O)(tolf-O,O?)(phen)(H2O)], [Mn2(mu 2-tolf-O,O?)2(tolf-O,O?)2(bipyam) 2], [Mn2(mu2-H2O) (mu2-tolf-O,O?)2(tolf-O)2(py) 4]·1.5MeOH·py, and [Mn(mu2-tolf-O, O?)2(DMF)2]n have been determined by X-ray crystallography. The interaction of the complexes with serum albumin proteins was investigated, and relative high binding constant values were calculated. The ability of the compounds to scavenge 1,1-diphenyl- picrylhydrazyl, 2,2?-azinobis(3-ethylbenzothiazoline-6-sulfonic acid), and hydroxyl radicals was evaluated, and [Mn(tolf)2(phen)(H 2O)] was the most active scavenger among the compounds. The compounds have also exhibited noteworthy in vitro inhibitory activity against soybean lipoxygenase. UV titration studies of the interaction of the complexes with calf-thymus (CT) DNA have proved the binding to CT DNA with [Mn(mu 2-tolf)2(DMF)2]n exhibiting the highest DNA-binding constant (Kb = 5.21 (±0.35) × 105 M-1). The complexes bind to CT DNA probably via intercalation as suggested by DNA-viscosity measurements and competitive studies with ethidium bromide (EB), which revealed the ability of the complexes to displace the DNA-bound EB.

Glycoside cleavage by a new mechanism in unsaturated glucuronyl hydrolases

Unsaturated glucuronyl hydrolases (UGLs) from GH family 88 of the CAZy classification system cleave a terminal unsaturated sugar from the oligosaccharide products released by extracellular bacterial polysaccharide lyases. This pathway, which is involved in extracellular bacterial infection, has no equivalent in mammals. A novel mechanism for UGL has previously been proposed in which the enzyme catalyzes hydration of a vinyl ether group in the substrate, with subsequent rearrangements resulting in glycosidic bond cleavage. However, clear evidence for this mechanism has been lacking. In this study, analysis of the products of UGL-catalyzed reactions in water, deuterium oxide, and dilute methanol in water, in conjunction with the demonstration that UGL rapidly cleaves thioglycosides and glycosides of inverted anomeric configuration (substrates that are resistant to hydrolysis by classical glycosidases), provides strong support for this new mechanism. A hydration-initiated process is further supported by the observed UGL-catalyzed hydration of a C-glycoside substrate analogue. Finally, the observation of a small beta-secondary kinetic isotope effect suggests a transition state with oxocarbenium ion character, in which the hydrogen at carbon 4 adopts an axial geometry. Taken together, these observations validate the novel vinyl ether hydration mechanism and are inconsistent with either inverting or retaining direct hydrolase mechanisms at carbon 1.

Study of some mixed ligand complexes of tertiary diimines and bidentate amide ligands

Stability constants of the ternary complexes of copper(II) with tertiary diimines as primary ligands and bidentate amides as secondary ligands have been determined by potentiometric titrations at 30 deg C in 50percent (v/v) aqueous dioxane at 0.2 M.The log KMAL values have been determined using the computer programme SCOGS.The complexes have been isolated in solid state and characterized by elemental analyses, conductivity and magnetic measurements and electronic and IR spectral studies.The order of stabilization in the ternary complexes (i.e. Deltalog K = log KMALMA – log K MLM values) has been explained on the basis of the electron repulsion concept.This has also been correlated with the shift in energy of the ligand field transition in the ternary complexes from the average value for the corresponding binary complexes.

The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 499-40-1 is helpful to your research., SDS of cas: 499-40-1

Lower rim 1,3-di-amide-derivative of calix[4]arene possessing bis-{N-(2,2?-dipyridylamide)} pendants: a dual fluorescence sensor for Zn2+ and Ni2+

Single crystal XRD structure of the lower rim 1,3-di-amide-derivative of calix[4]arene possessing bis-{N-(2,2?-dipyridylamide)} pendants (L) exhibit two distinct binding cores, viz., N4 and O6. L was found to be selective for Zn2+ by switch-on and for Ni2+ by switch-off fluorescence by forming 1:1 complexes. The binding and the composition of the complex formed have been addressed based on steady state and time-resolved fluorescence spectroscopy in addition to the absorption and ESI MS. As L can detect Zn2+ and Ni2+ to a concentration as low as 142 and 203 ppb, respectively, L can be a very sensitive molecular probe for these ions. The coordination details of the metal ion-bound complexes have been addressed based on ab initio calculations showing that the stabilization energies are commensurate with the coordination formed.

Stereospecific solution- and solid-phase glycosylations. Synthesis of beta-linked saccharides and construction of disaccharide libraries using phenylsulfenyl 2-deoxy-2-trifluoroacetamido glycopyranosides as glycosyl donors

An efficient strategy to construct beta-O-2-amino-2-deoxyglycopyranosidic linkages using glycosyl sulfoxides is demonstrated. Phenylsulfenyl 2-deoxy- 2-trifluoroacetamido glycopyranosides were found to be reactive glycosyl donors in both solid- and solution-phase glycosylations, affording the corresponding beta-glycosides exclusively and in high yield. The trifluoroacetamido group was removed under mild conditions, allowing orthogonal derivatization of multiple protected amino groups on an oligosaccharide or glycoconjugate. On the basis of the results with these glycosyl donors, a solid-phase beta-linked disaccharide library was constructed. The scope and flexibility of this approach will be discussed.

Design Strategies of Metal Complexes Based on Chelating Polymer Ligands and Their Application in Nanomaterials Science

The advances and problems associated with the synthesis, properties and structure of metal complexes based on chelating polymer ligands are presented and assessed. The polymeric metal chelates (PMCs) are divided into molecular, intracomplex, macrocyclic and polynuclear types, which in turn are grouped according to the nature of the donor atoms (N,N-, N,?-, N,S-, ?,?-, O,S-, S,S-, ?,?-chelates, etc.). The main attention is focused on the similarities and differences between low and high molecular weight metal chelates, as well as the spatial organization of PMCs. The most important areas of research in the field of such compounds are highlighted. Thermal transformations of metal complexes based on chelating polymer ligands leading to the formation of nanostructured materials are considered. The bibliography includes the articles published after 2010.

Synthesis, characterization, and photoluminescent studies of three-coordinate Cu(i)-NHC complexes bearing unsymmetrically-substituted dipyridylamine ligands

A series of heteroleptic three-coordinate Cu(i) complexes bearing monodentate N-heterocyclic carbene (NHC) ligands of the type 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene (IPr) and 1,3-bis(2,6-diisopropylphenyl)imidazolidin-2-ylidene (SIPr), and bidentate N-donor ligands of the type unsymmetrically-substituted dimethyl dipyridylamine (Me2Hdpa) and bis(mesityl)biazanaphthenequinone (mesBIAN) have been synthesized. The complexes [Cu(IPr)(3,4?-Me2Hdpa)]PF6, 1; [Cu(IPr)(3,5?-Me2Hdpa)]PF6, 2; [Cu(IPr)(3,6?-Me2Hdpa)]PF6, 3; [Cu(IPr)(mesBIAN)]PF6, 6; [Cu(SIPr)(3,4?-Me2Hdpa)]PF6, 7; [Cu(SIPr)(3,5?-Me2Hdpa)]PF6, 8; and [Cu(SIPr)(3,3?-Me2Hdpa)]PF6, 11 have been characterized by 1H and 13C NMR spectroscopies, elemental analysis, cyclic voltammetry, and photophysical studies in solid and solution phase. Single crystal X-ray structures were obtained for all complexes except 11. The crystallographic data reveal a mononuclear structure for all complexes with the copper atom ligated by one C and two N atoms. The UV-Vis absorption spectra of all dipyridylamine complexes in CH2Cl2 show a strong ligand-centered absorption band around 250 nm and a strong metal-to-ligand charge transfer (MLCT) band around 300 nm. When irradiated with UV light, the complexes exhibit strong emission maxima at 453-482 nm with photoluminescence quantum yields (PLQY) ranging from 0.21 to 0.87 in solid state. While the PLQY values are comparable to those of the symmetrical [Cu(IPr)(Me2Hdpa)]PF6 complexes, a stabilizing CH-pi interaction has been reduced in the current systems. In particular, complex 3 lacks any strong CH-pi interaction, but emits more efficiently than 1 and 2 wherein the interactions exist. Structural data analysis was performed to clarify the role of ligands’ plane angle and the NH/CH?F interactions to the observed light interaction of unsymmetrical [Cu(NHC)(Me2Hdpa)]PF6 complexes. DFT calculations were performed to assist in the assignment of the electronic structure and excited state behavior of the complexes.
