Kusama, Hitoshi; Arakawa, Hironori; Sugihara, Hideki published the artcile< Density functional study of imidazole-iodine interaction and its implication in dye-sensitized solar cell>, SDS of cas: 1003-21-0, the main research area is imidazole iodine interaction dye sensitized solar cell; charge transfer complex imidazole iodine density functional theory.

The monomer and charge-transfer complexes of 14 different imidazole derivatives with diiodine were studied by a d. functional theory (DFT) method. DFT calculations revealed that the σ* orbital of iodine interacts with the nitrogen lone pair of imidazoles at position 3. The influence of these imidazoles addition on the performance of a bis(tetrabutylammonium)cis-bis(thiocyanato)bis(2,2′-bipyridine-4-carboxylic acid, 4′-carboxylate)ruthenium(II) (N719) dye-sensitized nanocrystalline TiO2 solar cell with an I-/I3- redox electrolyte in acetonitrile was also studied. All of the imidazole derivatives enhanced the open-circuit photovoltage (Voc). The resulting Voc values of solar cell were compared to computational calculations on the interaction between imidazoles and I2 by a DFT method. Optimized geometries, frequency analyses, and interaction energies suggest that the V oc value is higher, the more the imidazole complexes with I2.

Won, Jong Hoon; Kim, Seok Kyun; Shin, In Chul; Ha, Hae Chan; Jang, Ji Min; Back, Moon Jung; Kim, Dae Kyong published the artcile< Dopamine transporter trafficking is regulated by neutral sphingomyelinase 2/ceramide kinase>, Recommanded Product: p-Benzenediacrylanilide, 4′,4′′-di-2-imidazolin-2-yl-, dihydrochloride, the main research area is dopamine ceramide kinase SMase2 C1P CERK signaling cortex pheochromocytoma; Ceramide; Ceramide-1-phosphate; Dopamine transporter; Neutral sphingomyelinase 2; Sphingomyelin pathway; Trafficking.

Dopamine (DA) reuptake is the primary mechanism to terminate dopaminergic transmission in the synaptic cleft. The dopamine transporter (DAT) has an important role in the regulation of DA reuptake. This study provides anatomical and physiol. evidence that DAT recycling is regulated by ceramide kinase via the sphingomyelin pathway. First, the results show that DAT and neutral sphingomyelinase 2 (nSMase2) were successfully co-precipitated from striatal samples and were colocalized in the mouse striatum or PC12 cells. We also identified a protein-protein interaction between nSMase2 and DAT through in situ proximity ligation assay experiments in the mouse striatum. Second, dopamine (DA) stimulated the formation of ceramide and increased nSMase activity in PC12 cells, while treatment with a cell-permeable ceramide-1-phosphate (C1P) increased DA uptake. Third, we used inhibitors and siRNA to inhibit nSMase2 and ceramide kinase and observed the effects on DAT recycling in PC12 cells. Treatment with ceramide kinase inhibitor K1, or nSMase inhibitor GW4869, decreased DA uptake in PC12 cells, although the application of FB1, a ceramide synthase inhibitor, did not affect DA uptake. Transfection of nSMase2 and CERK siRNA decreased DAT surface level in PC12 cells. These results suggested that SM-derived C1P affects cell surface levels of DAT.

Yan, Kui; Bai, Zhengwu; Huang, Shaohua published the artcile< NMR signal separation of ionic liquids by poly(sodium-p-styrenesulfonate)-assisted chromatographic NMR spectroscopy>, Application of C6H9ClN2O2, the main research area is ionic liquid polysodium styrenesulfonate chromatog NMR spectroscopy.

Diffusion-ordered NMR spectroscopy (DOSY), dubbed chromatog. NMR spectroscopy, can be used to simultaneously distinguish and identify the structures of components in a mixture according to their different diffusion coefficients In order to improve the resolution of DOSY on the diffusion dimension, a lot of matrixes have been developed to expand the application of this technique in mixture anal. However, there is no matrix to detect the mixture of ionic liquids (ILs). Herein, we introduced a new matrix, poly(sodium-p-styrenesulfonate) (PSSNa), which can be used to fully sep. the signals of a mixture of different ILs. The mixture of three imidazolium ILs of 1-butyl-3-methylimidazolium bromide, 1-allyl-3-vinylimidazolium bromide and 1-carboxymethyl-3-methylimidazolium chloride could be fully distinguished by virtue of their different interactions with PSSNa. We also investigated the influences of PSSNa amount, IL concentration and solution pH value on the signal resolution of mixtures This work provides a scientific reference for the anal. of the other IL analytes.

The extent of thermodn. stabilization of telomeric G-quadruplex (G4) by isomers of G4 ligand L2H2-6OTD, a telomestatin analog, is inversely correlated with susceptibility to S1 nuclease. L2H2-6OTD facilitated the S1 nuclease activities through the base flipping in G4, unlike the conventional role of G4 ligands which inhibit the protein binding to DNA/RNA upon ligand interactions.

The cell-to-cell transmission of viral resistance is a potential mechanism for amplifying the interferon-induced antiviral response. In this study, we report that interferon-α (IFN-α) induced the transfer of resistance to hepatitis B virus (HBV) from nonpermissive liver nonparenchymal cells (LNPCs) to permissive hepatocytes via exosomes. Exosomes from IFN-α-treated LNPCs were rich in mols. with antiviral activity. Moreover, exosomes from LNPCs were internalized by hepatocytes, which mediated the intercellular transfer of antiviral mols. Finally, we found that exosomes also contributed to the antiviral response of IFN-α to mouse hepatitis virus A59 and adenovirus in mice. Thus, we propose an antiviral mechanism of IFN-α activity that involves the induction and intercellular transfer of antiviral mols. via exosomes.

Mardaneh, Jalal; Beyzaei, Hamid; Hashemi, Seyed Hadi; Ghasemi, Behzad; Rahdar, Abbas published the artcile< Comparative evaluation of the inhibitory potential of synthetic N-heterocycles, Cu/Fe3O4@SiO2 nanocomposites and some natural products against non-resistant and antibiotic-resistant Acinetobacter baumannii>, Application In Synthesis of 30086-64-7, the main research area is Acinetobacter Trachyspermum thiazole iron oxide silicon dioxide nanocomposite antibacterial.

Acinetobacter baumannii is a common infectious agent in hospitals. New antimicrobial agents are identified and prepared to combat these bacterial pathogens. In this context, the blocking potentials of a series of synthesized N-heterocyclic compounds, Cu/Fe3O4@SiO2 nanocomposites, glycine, poly-L-lysine, nisin and hydroalcoholic extracts of Trachyspermum ammi, Curcuma longa and green tea catechins were evaluated against non-resistant and multidrug-resistant strains of A. baumannii. Solutions of heterocyclic derivatives and hydroalcoholic extracts of Trachyspermum ammi, Curcuma longa and green tea catechins were prepared at initial concentration of 10240μg ml-1 in 10% DMSO. Other compounds were dissolved in water at the same concentrations Their in vitro inhibitory activity was assessed by determination of IZD, MIC and MBC values. Glycine, poly-L-lysine, nisin, Curcuma longa and green tea catechins extracts, and thiazoles 3a, 3d and 3f were ineffective at their initial concentrations Heterocyclic derivatives 7a-f, 3c, 3e and 3h, Cu/Fe3O4@SiO2 nanocomposites and Trachyspermum ammi extract could block the growth of bacterial strains with IZDs (7.40-15.51 mm), MICs (32-1024μg ml-1) and MBCs (128-2048μg ml-1). Among synthetic chems. and natural products, the best antimicrobial effects were recorded with (E)-2-(5-acetyl-4-methylthiazol-2-yl)-2-(thiazolidin-2-ylidene)acetonitrile (7b) and the extract of Trachyspermum ammi. It is imperative that their toxic and histopathol. effects were assessed in future researches. It is predicted that the essential oil of Trachyspermum ammi will improve its antibacterial activities.

Liu, Chu-Xiao; Guo, Si-Kun; Nan, Fang; Xu, Yi-Feng; Yang, Li; Chen, Ling-Ling published the artcile< RNA circles with minimized immunogenicity as potent PKR inhibitors>, SDS of cas: 452-06-2, the main research area is RNA immunogenicity PKR inhibitor; PKR; PKR inhibitor; T4 RNA ligase; circular RNA; circular RNA structure; dsRNA; group I intron; immune response; permuted Anabaena pre-tRNA group I intron; phage T4 thymidylate synthase gene.

Exon back-splicing-generated circular RNAs, as a group, can suppress double-stranded RNA (dsRNA)-activated protein kinase R (PKR) in cells. We have sought to synthesize immunogenicity-free, short dsRNA-containing RNA circles as PKR inhibitors. Here, we report that RNA circles synthesized by permuted self-splicing thymidylate synthase (td) introns from T4 bacteriophage or by Anabaena pre-tRNA group I intron could induce an immune response. Autocatalytic splicing introduces ∼74 nt td or ∼186 nt Anabaena extraneous fragments that can distort the folding status of original circular RNAs or form structures themselves to provoke innate immune responses. In contrast, synthesized RNA circles produced by T4 RNA ligase without extraneous fragments exhibit minimized immunogenicity. Importantly, directly ligated circular RNAs that form short dsRNA regions efficiently suppress PKR activation 103- to 106-fold higher than reported chem. compounds C16 and 2-AP, highlighting the future use of circular RNAs as potent inhibitors for diseases related to PKR overreaction.
