Electric Literature of 499-40-1, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 499-40-1, Name is (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal, molecular formula is C12H22O11.

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 ¡Á 103 M-1 and 3.1 ¡Á 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.

A binuclear Zn(II) complex [Zn2(SDBA)2(DPA)2.2H2O] (1) (DPA = di-2-pyridylamine, H2SDBA = 4,4?- sulfonyldibenzoic acid) is synthesized and characterized using single crystal X-ray diffraction, IR spectroscopy, and elemental analysis. The single crystal X-ray diffraction analysis reveals that complex 1 is a binuclear zinc(II) complex. The binuclear molecules are further connected by three types of N?H..O, C?H..O, and O?H..O hydrogen bonds, generating a three-dimensional supramolecular structure. Meanwhile, S?O..pi interactions further consolidate the three-dimensional supramolecular framework of 1. In addition, the thermal stability and luminescent properties of the title complex are briefly investigated. The luminescence measurements reveal that complex 1 exhibits fluorescent emission in the solid state at room temperature.

The rational design of anticancer agents that acts in specific biological targets is one of the most effective strategies for developing chemotherapeutic agents. Aiming at obtaining new ruthenium (II) compounds with good cytotoxicity against tumor cells, a series of new complexes of general formula [RuCl(PPh3)(Hdpa)(N?N)]Cl [PPh3 = triphenylphosphine, N-N = 2,2?-dipyridylamine (Hdpa) (1), 1,2-diaminoethane (en) (2), 2,2?-bipyridine (bipy) (3), 5,5?-dimethyl-2,2?-bipyridine (dmbipy) (4), 1,10-phenanthroline (phen) (5) and 4,7-diphenyl-1,10-phenanthroline (dphphen) (6)] were synthesized. The complexes were characterized by elemental analysis and spectroscopic techniques (IR, UV/Visible, and 1D and 2D NMR) and three of their X-ray structures were determined: [RuCl(PPh3)(Hdpa)2]Cl, [RuCl(PPh3)(Hdpa)(en)]Cl and [RuCl(PPh3)(Hdpa)(dmbipy)]Cl. All the complexes are more cytotoxic against the cancer cell line than against the non-tumor cell line, highlighting complexes 1 and 5, which have an index selectivity of 18 and 15, respectively. The binding constants of compounds 1?6 with human serum albumin (HSA) were determined by tryptophan fluorescence quenching, indicating moderate to strong interactions. The binding mode of the complexes to calf thymus (CT) DNA was explored by several techniques, which reveal that only the dphphen compound 6 causes distortions in the secondary and tertiary structures of DNA. The studies demonstrated that the nature of the N?N co-ligand and the presence of the PPh3 and Hdpa ligands are features that can influence the binding affinity of the complexes by the biomolecules and in the cytotoxic activity of the complexes. Overall, the complexes with diimine co-ligand are much more cytotoxic than compound 2 with the aliphatic diamine.

Application of 499-40-1. Let¡¯s face it, organic chemistry can seem difficult to learn. Especially from a beginner¡¯s point of view. Like 499-40-1, Name is (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal. In a document type is Article, introducing its new discovery.

The solvent-free reactions of lanthanum, gadolinium and ytterbium metal with molten 2,2?-Dipyridylamine gave crystalline [Ln(N(C5H 4N)2)3]2, Ln = La, Gd, Yb, the crystals being colourless to transparent yellow. They are the first examples of dipyridylamides of the rare earth elements. All compounds are homoleptic and exhibit pure nitrogen coordinations of the metal atoms. In addition to end-on chelating dipyridylamide groups further amide ligands are bridging via double chelates using all three nitrogen atoms for coordination. The structures consist of dimers without metal-metal bonds. Because of the large differences in the ionic radii of LaIII, GdIII and YbIII the coordination spheres differ, arranging the binding modes differently though the stoichiometry is similar. Gd and Yb show a C.N. of eight while La has a C.N. of ten nitrogen atoms. This results in distinctively different crystal structures and IR spectra.

Some ternary Cu(dipyam)(OOCR)(OR) complexes (dipyam = 2,2?-dipyridylamine; RCOO- = acetate, benzoate, cmb (2-chloro-5-methylthio-benzoate), mta (methylthioacetate), mtn (2-methylthio-nicotinate); OR- = pnp (p-nitrophenolate), dcp (2,6-dichlorophenolate), tcp (2,4,6-trichlorophenolate)) have been synthesized. Their IR spectra are included and the X-ray diffraction structure is given for the crystals of [Cu(dipyam)(OOCCH3)(dcp)] (I), [Cu(dipyam)(mta)(dcp)] (II), [Cu(dipyam)(mtn)(dcp)] (III) and [Cu(dipyam)(cmb)(tcp)] (IV). The copper coordination is square pyramidal in I, with a rather rare axial position of the phenolate ligand, while in II and III is distorted octahedral with equatorial phenolate and weak apical bonds (II Cl, S; III Cl, O). The copper coordination in IV can be better described as square planar, but with distortion toward a flattened tetrahedral geometry and with a rather long apical Cu-O distance, involving an oxygen of the carboxylate ion. The entrance of the phenolate in an axial or equatorial position is due to the geometry imposed to the complex by the auxiliary ligand.

N,N-bis(carboxymethyl)-1-adamantylamine acid (H2BCAA) or N-(1-adamantyl)-iminodiacetic acid forms zwitterions that are intra-stabilized by a ‘bifurcated’ N+-H…O(carboxyl)2 interaction. In the crystal, both half-protonated carboxyl groups of H2BCAA ¡À are involved in linear O-H…O intermolecular bridges of 2.46 A. In the studied BCAA-CuII derivatives, the iminodiacetate-moiety of the BCAA chelating ligand exhibits a mer-NO2 conformation in [Cu(BCAA)(H2O)2] (1) and [Cu(BCAA)(Him)]2 (2), but fac-O2+N(apical) conformation in Cu(BCAA)(bpy)(H2O)]¡¤3.5H2O (3) [Him = imidazole, bpy =2,2?-bipyridine]. In clear contrast, dipyridylamine (dpya), as auxiliary ligand, seems to be unable to promote the fac-O2+N(apical) conformation in BCAA, as reveal the structures of two new salts with the trinuclear cation [(dpya)2Cu-mu2-Cu(BCAA) 2-Cu(dpya)2]2+ and the anions [Cu(BCAA) 2]2- (4) or NO3- (5), respectively.

In the ionic title compound, [Ni(NO3)(C10H9N3)2]NO3, the central NiII atom exhibits cis-NiN4O2 octahedral coordination with three chelating ligands, viz. one nitrate anion and two di-2-pyridylamine (dpya) molecules. A second nitrate group acts as a counter-ion. The complex cations and the nitrate anions are also linked by N – H…O hydrogen bonds. The compound was prepared in two different reproducible ways: direct synthesis from Ni(NO3)2 and dpya yielded systematically twinned crystals (the twinning law is discussed), while single crystals were obtained unexpectedly from the Ni(NO3)2/dpya/maleic acid/NaOH system.
