In this study, a viscoelastic surfactant (VES), named VES-Q, with erucyl amide tails and cyclodextrin was successfully synthesized, and the phase behavior of aqueous VES solutions at different salt concentrations was observed. In addition, the size of the molecules under different salt types was measured using dynamic light scattering. The viscosity of VES-Q in salt solution corresponds to the molecular size of the surfactant was found. Due to the high salinity tolerance of VES-Q to common formation salts, we used formation water from West Sichuan and seawater the Gulf of Mexico to allocate VES-Q to two clean fracturing fluids, namely, fluid 1 and fluid 2, with a concentration of 2%. Rheological properties under high-temperature reservoir conditions were simulated. The clean fracturing fluid was prepared by the VES-Q method, and its performance met the requirements of hydraulic fracturing operations.

Thesynthetic method for previously unknown 11-mercaptoundecanoyl hydrazones of the aldose series (L-arabinose, D-ribose, D-xylose, L-rhamnose, L-fucose, D-mannose, D-galactose, D-glucose, N-acetyl-D-glucosamine, N-acetyl-D-mannosamine, D-lactose, D-maltose) was developed, and structures of the productes were determined. These compounds are perspective glycoligands for noble metal nanoparticles. The H-1 and C-13 NMR spectroscopy data show that most of these aldose 11-mercaptoundecanoyl hydrazones in DMSO-d(6) solution exist as a tautomeric mixture of open hydrazone and cyclic pyranose forms. The linear hydrazone form is represented by a set of Z ‘,E ‘-conformational isomers, differing in the arrangement of substituents relative to the amide bond C-N, in comparable amounts. In the case of 11-mercaptoundecanoyl hydrazones derived from D-glucose, D-lactoseand D-maltose, the cyclic pyranose structure represented by alpha,beta-configurational isomers is retained.

5,10,15,20-tetra(4-aminophenyl)porphyrinatonickel(II) was covalently connected to multi-walled carbon nanotube (MWCNT) through an amide linkage and characterized by using many spectroscopic techniques. In FT-IR, the carbonyl peak (C = O) of MWCNT-NiTAP is shifted to higher frequency as compared to the reported MWCNT-TAP due to Ni ion substitution. Notable changes in the FT-IR and XP spectra confirms the covalent functionalization of Ni-TAP with MWCNTs. Raman spectra indicate that the ID/IG ratio is less for MWCNT-NiTAP as compared to MWCNT, MWCNT-COOH, MWCNT-ZnTAP and MWCNT-CuTAP which is due to improved electronic properties of MWCNT-NiTAP. TGA plots of MWCNT-NiTAP reveals that similar to 30% weight loss in the temperature range of 150-800 degrees C. Considerable shift in the absorption and emission spectra of the nano hybrid clearly indicate different electronic interaction between porphyrin and MWCNT due to nickel ion substitution. PL spectra of MWCNT-NiTAP exhibited fluorescence quenching of Ni-TAP Soret band by MWCNTs. This quenching is owing to the energy or electron transfer between Ni-TAP and MWCNTs.

In this study, new tri-amides 5a-1 have been synthesized via a one-pot four-component Ugi reaction between repaglinide, aniline derivatives, aldehyde derivatives, and cyclohexyl isocyanide in good yields. These compounds were evaluated against yeast alpha-glucosidase. Obtained in vitro alpha-glucosidase results demonstrated that all the synthesized compounds 5a-1 were more potent than standard inhibitor acarbose. Among them, the most potent compounds were compounds 5j, 5k, and 5h. The kinetic analysis of the most potent compound 5j revealed that this compound is a competitive inhibitor for alpha-glucosidase (K-i = 24 mu M). Furthermore, docking study of the most potent compounds was also performed in the alpha-glucosidase active site to find interaction modes and binding energies of these compounds.

BACKGROUNDAquatic source gelatins are gaining more attention due to the advantages in safety and religion acceptability compared with mammalian sources. For understanding the effects of extracting temperature on gelatins from chum salmon (Oncorhynchus keta) skins (GCSS), gelatins were extracted at temperatures from 40 to 90 degrees C and the physiochemical properties of GCSS were investigated. RESULTSGCSS yield increased while imino acids content declined as the increase of temperature. GCSS40, 50 and 60 showed strong -, 1- and 2-chains but the three faded in GCSS70, 80 and 90, with the presence of low molecular weight fragments. Amides A, I and III were shifted to higher wavenumber in GCSS70, 80 and 90 compared with that of GCSS40, 50 and 60. X-ray diffraction showed lower intensity of peak at 7 degrees in GCSS80 and 90 than in the other GCSS. Gel strength declined while a*, b* and E* value increased as temperature increased. Foam expansion and stability of GCSS40, 50 and 60 were lower than those of GCSS70, 80 and 90. Emulsion activity and stability decreased as temperature increased. CONCLUSIONExtracting temperature greatly affected yield, molecular composition and functionalities of GCSS. A temperature lower than 50 degrees C is recommended for GCSS extraction.

To investigate the synergistic coordination ability of a polytorsional-amide ligand to construct new coordination polymers (CPs), N,N’-bis(4-methylpyridin-4-yl)-1,4-naphthalenediamide (L) was selected as the main ligand. Ni2+ and Cu2+ with electrochemical activity and different carboxylates [2-nitrobenzoic acid (2-HNBA), 4-nitrobenzoic acid (4-HNBA), p-toluic acid (HPTA), 1,2-benzenedicarboxylic acid (1,2-H2BDC), pimelic acid (H2PIM), 1,3-phenylenediacetic acid (H(2)PDA), o-methylsalicylic acid (HOMSA), propanedioic acid (H2PRO) and azelaic acid (H(2)AZE)] have been selected, and ten new CPs were obtained: [Ni(L)(2)(2-NBA)(2)] (1), [Ni(L)(4-NBA)(2)(H2O)(2)] (2), [Ni(L)(PTA)(2)(H2O)(2)] (3), [Ni(L)(1,2-BDC)(H2O)(3)]center dot H2O (4), [Ni(L) (PDA)]center dot 0.5H(2)O (5), [Ni(L)(PIM)]center dot 0.5H(2)O (6), [Cu(L)(4-NBA)(2)] (7), [Cu(L)(OMSA)2(H2O)] (8), [Cu(L)(PRO) (H2O)]center dot 3H(2)O (9) and [Cu(L)(AZE)(H2O)] (10). The ten CPs were structurally determined through single-crystal X-ray diffraction analyses, PXRD and IR spectra. 1, 5, 6 and 10 are the 4-connected 2D networks. 2 and 3 are similar racemic chains. 4 and 7 are 1D helical structures. 8 is a zigzag chain and 9 is a U type chain. The effects of the twist degrees of the amide ligands and the coordination features of the carboxylates/metal ions on the structures and properties of the target CPs were investigated. 1-10 modified carbon paste electrodes (n-CPEs) display a quasi-reversible oxidation-reduction process at the surface of the n-CPE. Representative CPs (2, 5, 7 and 10) show good electrochemical sensing properties for ascorbic acid (AA) and chloramphenicol (CAP).

1. The absorption, metabolism, and excretion of a single oral 450-mg dose of [C-14]-(S)-6-(3-cyclopentyl-2-(4-trifluoromethyl)-1H-imidazol-1-yl)propanamido)nicotinic acid (PF-04991532), a hepatoselective glucokinase activator, was investigated in humans. Mass balance was achieved with similar to 94.6% of the administered dose recovered in urine and feces. The total administered radioactivity excreted in feces and urine was 70.6% and 24.1%, respectively. Unchanged PF-04991532 collectively accounted for similar to 47.2% of the dose excreted in feces and urine, suggestive of moderate metabolic elimination in humans. 2. The biotransformation pathways involved acyl glucuronidation (M1), amide bond hydrolysis (M3), and CYP3A4-mediated oxidative metabolism on the cyclopentyl ring in PF-04991532 yielding monohydroxylated isomers (M2a-d). Unchanged PF-04991532 was the major circulating component (64.4% of total radioactivity) whereas M2a-d collectively represented 28.9% of the total plasma radioactivity. 3. Metabolites M2a-d were not detected systemically in rats and dogs, the preclinical species for the toxicological evaluation of PF-04991532. In contrast, cynomologus monkeys dosed orally with unlabeled PF-04991532 revealed M2a-d in circulation, whose UV abundance was comparable to the profile in humans. This observation suggested that monkeys could potentially serve as a non-rodent alternative for studying the toxicity of PF-04991532 and its metabolites M2a-d. 4. The present results are in excellent agreement with our previously generated metabolite scouting data, which provided preliminary evidence for the disproportionate metabolism of PF-04991532 in humans.

Now introduce a scientific discovery about this category.

Thyroid cancer holds the first place of the malignant tumors of the endocrine system. One of the less common thyroid cancers is follicular thyroid carcinoma (FTC), which is very difficult to diagnose because it gives the same image as adenoma, which is benign. Certainty of the diagnosis is gained only when FTC gives metastases. Therefore, it was decided to compare normal and neoplastic (FTC) thyroid tissues with Fourier Transform Infrared (FTIR) spectroscopy. The obtained FTIR spectra and Principal Component Analysis (PCA) allowed us to conclude that there are differences in the FTIR spectrum between normal tissues and those affected by cancer. In addition, the results indicate that there is a decrease in the number of functional groups that build cellular and tissue structures in tumoral tissues. The shifts of wave numbers corresponding to the protein and lipid function group vibrations, as well as the calculated second derivative of the FTIR spectra showed the structural changes in neoplastic tissues. Moreover, the deconvolution of the amide I massif indicates that in cancerous tissues the prevailing secondary structure is beta-sheet structure, while in normal tissues it is alpha-helix. The obtained results allow us to conclude that infrared spectroscopy, in addition to providing information on the composition of tested samples, can be an excellent diagnostic tool contributing to understanding the Fit substrate.
