Electrochemical dissolution of sacrificial Pd anode was used to synthesize novel polynuclear PdII complexes with ligands based on polyamic acids containing in the main chain biquinolyl groups capable of coordination to the metal ions. The synthesized polymeric complexes exhibit high catalytic activity in the Suzuki reaction. The reaction can be run under mild conditions, at 40 C and with a sufficiently high product yield at a catalyst concentration of 0.05 mol.% (with respect to the starting aryl halide). The polymeric ligand allows immobilization of the catalyst on the graphite fabric with high specific surface area that enhances the catalyst turnover number and promotes its recycling.

The protein p56 lymphoid T cell tyrosine kinase (Lck) is predominantly expressed in T lymphocytes where it plays a critical role in T-cell-mediated immune response. Lck participates in phosphotyrosine-dependent protein-protein interactions through its modular binding unit, the Src homology-2 (SH2) domain. Accordingly, virtual screening methods combined with experimental assays were used to identify small molecular weight nonpeptidic compounds that block Lck SH2 domain-dependent interactions. Virtual screening included scoring normalization procedures and postdocking structural clustering that is shown to facilitate the selection of active compounds. By targeting the well-defined hydrophobic binding pocket known to impart specificity on Lck-protein interactions (i.e., pY + 3 site), inhibitors of the Lck SH2 domain were discovered that omit the phosphotyrosine (pY) or related moieties. The 34 out of 196 computationally selected compounds were shown to inhibit Lck SH2 domain association with phosphorylated immunoreceptor tyrosine based activation motifs peptide. Twenty-four of the active compounds were further tested for their ability to modulate biological function. Thirteen of these compounds showed inhibitory activity in mixed lymphocyte culture assay. Flourescence titration experiments on four of these active compounds further verified their binding to the SH2 domain. Because of their simple chemical structures, these small organic compounds have the potential to act as lead compounds for the development of novel immunosuppressant drugs.

Nanocrystalline (anatase), mesoporous TiO2 thin films were functionalized with [Ru(bpy)2(deebq)]-(PF6)2, [Ru(bq)2(deeb)](PF6)2, [Ru(deebq) 2(bpy)](PF6)2, [Ru(bpy)(deebq)(NCS) 2], or [Os(bpy)2(deebq)](PF6)2, where bpy is 2,2?-bipyridine, bq is 2,2?-biquinoline, and deeb and deebq are 4,4?-diethylester derivatives. These compounds bind to the nanocrystalline TiO2 films in their carboxylate forms with limiting surface coverages of 8 (± 2) × 10-8 mol/cm2. Electrochemical measurements show that the first reduction of these compounds (-0.70 V vs SCE) occurs prior to TiO2 reduction. Steady state illumination in the presence of the sacrificial electron donor triethylamine leads to the appearance of the reduced sensitizer. The thermally equilibrated metal-to-ligand charge-transfer excited state and the reduced form of these compounds do not inject electrons into TiO2. Nanosecond transient absorption measurements demonstrate the formation of an extremely long-lived charge separated state based on equal concentrations of the reduced and oxidized compounds. The results are consistent with a mechanism of ultrafast excited-state injection into TiO2 followed by interfacial electron transfer to a ground-state compound. The quantum yield for this process was found to increase with excitation energy, a behavior attributed to stronger overlap between the excited sensitizer and the semiconductor acceptor states. For example, the quantum yields for [Os(bpy)2(dcbq)]/TiO2 were phi(417 nm) = 0.18 ± 0.02, phi(532.5 nm) = 0.08 ± 0.02, and phi(683 nm) = 0.05 ± 0.01. Electron transfer to yield ground-state products occurs by lateral intermolecular charge transfer. The driving force for charge recombination was in excess of that stored in the photoluminescent excited state. Chronoabsorption measurements indicate that ligand-based intermolecular electron transfer was an order of magnitude faster than metal-centered intermolecular hole transfer. Charge recombination was quantified with the Kohlrausch-Williams-Watts model.

DNA polymerase beta (beta-pol) plays a central role in repair of damaged DNA bases by base excision repair (BER) pathways. A predominant phenotype of beta-pol null mouse fibroblasts is hypersensitivity to the DNA-methylating agent methyl methanesulfonate. Residues in the 8-kDa domain of beta-pol that seem to interact with a known natural product beta-pol inhibitor, koetjapic acid, were identified by NMR chemical shift mapping. The data implicate the binding pocket as the hydrophobic cleft between helix-2 and helix-4, which provides the DNA binding and deoxyribose phosphate lyase activities of the enzyme. Nine structurally related synthetic compounds, containing aromatic or other hydrophobic groups in combination with two carboxylate groups, were then tested. They were found to bind to the same or a very similar region on the surface of the enzyme. The ability of these compounds to potentiate methyl methanesulfonate cytotoxicity, an indicator of cellular BER capacity, in wild-type and beta-pol null mouse fibroblasts, was next ascertained. The most active and beta-pol-specific of these agents, pamoic acid, was further characterized and found to be an inhibitor of the deoxyribose phosphate lyase and DNA polymerase activities of purified beta-pol on a BER substrate. Our results illustrate that NMR-based mapping techniques can be used in the design of small molecule enzyme inhibitors including those with potential use in a clinical setting.

The effect of organic acid on self-assembly process: Syntheses and characterizations of six novel cadmium(II)/zinc(II) complexes derived from mixed ligands

Using the principle of crystal engineering, six metal-organic coordination polymers, [Cd(bdc)(3-pytpy)]n ¡¤ 2nH2O (1), [Cd(bdc)0.5(3-pytpy)]n ¡¤ n(ClO4) (2), Cd(ndc)0.5(3-pytpy)]n ¡¤ n(ClO4) (3), [Zn(ndc)(3-pytpy)]n (4), [Cd(bqdc)(3-pytpy)]n (5), and [Zn(pam)(3-pytpy)]n ¡¤ 2nH2O (6) (H2bdc = benzene-1,4-dicarboxylic acid, H2ndc = naphthalene-2,6-dicarboxylic acid, H2bqdc = 2,2?-biquinoline-4,4?-dicarboxylic acid, H2pam = pamoic acid), were synthesized and structurally characterized by elemental analyses, IR spectroscopy, and single-crystal X-ray diffraction analyses. Compounds 1-6 crystallize in the presence of organic-acid linkers as well as multi-functional N-donor ligand 4?-(3-pyridyl)-2,2?:6?,2??-terpyridine (3-pytpy). In complexes 1, 4, 5, and 6, the dicarboxylate as bridging ligand connects metal atoms to form the main body of 1D zigzag chains for 1 and 4, nearly linear chain for 5 and helical chain for 6, while 3-pytpy as tridentate chelating ligand is just like lateral arm grafting on both sides of these chains. In complexes 2 and 3, both the dicarboxylate and 3-pytpy as bridging ligands connect metal atoms into 2D polymeric structure for 2 and 1D chain of alternating loops and rods for 3. The weak interactions such as hydrogen bonding and pi¡¤¡¤¡¤pi stacking were investigated on the formation of superamolecular structures and the influence of organic acid on the formation of the final structures was discussed.

Water-soluble copper(i) complexes bearing 2,2?-bicinchoninic acid dipotassium salt with red-light absorption and repeatable colour change upon freezing operation

We newly synthesized a copper(i) complex bearing a 2,2?-bicinchoninic acid dipotassium salt (biq(COOK)2) ligand and characterized the complex by elemental analysis, NMR and UV-vis spectroscopy, and electrochemistry with the help of comparative compounds. The complex in water shows intense absorption in the red light region due to metal to ligand charge transfer. The wavelength value at the absorption maximum of the charge transfer, lambdaabs_max, is 556 nm, and the value of the molar extinction coefficient, epsilon, at the shoulder of the absorption at 670 nm is 1 ¡Á 103 M?1 cm?1. The water solution is purple, and the frozen one is green. The colour change is repeatable. The colour change is not observed when DMSO and ethanol are used. The UV-vis spectra related to absorption using an integrated sphere of the water solution and a frozen one show the repeatable colour change.

Peptide Functionalization Through the Generation of Selenocysteine Electrophile

Herein we report the first example of a strategy for peptide functionalization through the generation of selenocysteine electrophile in 5- and 6-endo-dig cyclization reactions. This simple approach allows bio-conjugation of selenocystine-based peptides. The developed protocol is based on copper(II) bromide mediated reactions of selenocystine with either 2-propargyl N-heterocycles through 5-endo-dig closure or with 2-ethynylbiaryls through 6-endo-dig closure. It allows construction of indolizinium moiety on selenocysteine residue as well as formation of polyaromatic fragment bonded to selenium in a simple one-pot process under mild reaction conditions.

Identification of some novel AHAS inhibitors via molecular docking and virtual screening approach

Acetohydroxyacid synthase (AHAS; EC 2.2.1.6) catalyzes the first common step in branched-chain amino acid biosynthesis. This enzyme is an important target for the design of environmental-benign herbicides. Based on the crystal structure of AHAS/sulfonylurea complex, we have carried out computational screening of the ACD-3D database in order to look for novel non-sulfonylurea inhibitors of AHAS for the first time. Three novel compounds were found to inhibit plant AHAS in vitro among 14 procured compounds. One compound showed promising activity in vivo for rape root growth inhibition bioassay. This research provided useful clues for further design and discovery of AHAS inhibitors.
