Royal jelly (RJ) from honeybee has been widely used as a health promotion supplement. The major royal jelly proteins (MRJPs) have been identified as the functional component of RJ. However, the question of whether MRJPs have anti-senescence activity for human cells remains. Human embryonic lung fibroblast (HFL-I) cells were cultured in media containing no MRJPs (A), MRJPs at 0.1 mg/ml (B), 0.2 mg/ml (C), or 0.3 mg/ml (D), or bovine serum albumin (BSA) at 0.2 mg/ml (E). The mean population doubling levels of cells in media B, C, D, and E were increased by 12.4%, 31.2%, 24.0%, and 10.4%, respectively, compared with that in medium A. The cells in medium C also exhibited the highest relative proliferation activity, the lowest senescence, and the longest telomeres. Moreover, MRJPs up-regulated the expression of superoxide dismutase-1 (SOD1) and down-regulated the expression of mammalian target of rapamycin (MTOR), catenin beta like-1 (CTNNB1), and tumor protein p53 (TP53). Raman spectra analysis showed that there were two unique bands related to DNA synthesis materials, amide carbonyl group vibrations and aromatic hydrogens. These results suggest that MRJPs possess anti-senescence activity for the HFL-I cell line, and provide new knowledge illustrating the molecular mechanism of MRJPs as anti-senescence factors.

We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 5680-79-5. The above is the message from the blog manager. Quality Control of H-Gly-OMe.HCl.

High functional group compatibility of iridium-catalyzed synthesis of enamines from amides and 1,1,3,3-tetramethyldisiloxane (TMDS) realized facile access of a series of donor (D)-pi-acceptor (A)-conjugated enamines, in which enamine behaves as a donor functional group. The amide precursors containing reducible functional groups, such as halogen, carbonyl, and nitro groups, underwent reaction with TMDS to give the corresponding enamines in high yields. In most cases, chemoselective hydrosilane reduction of the amide group occurred while other reducible groups remained intact. Absorption and emission properties including solvatochromic behavior for the resulting D-pi-A-conjugated enamines were determined using UV-visible and fluorescent spectra, which provided an understanding of the donor properties of the CH=CHNPh2 group and photofunctional properties of the D-pi-A conjugated enamines as a fluorescent dye. Maximum absorption wavelength (lambda(abs)) of p-ZC(6)H(4)CH=CHNPh2 was predictable from lambda(abs) of p-ZC(6)H(4)NPh(2), which was supported by density functional theory calculations. Some of the D-pi-A-conjugated enamines showed fluorescence with moderate fluorescence quantum yields (Phi(fl)). Of interest are unusually emissive pi-conjugated enamines containing a nitro group, which generally behaves as strong quenchers of fluorescence. The additive effect of B(C6F5)(3) resulted in significant red shifts of lambda(abs) and lambda(fl). In some cases, high Phi(fl) was observed in the solution state.

Renewable sources – namely, algae oil and diacids – were used for the synthesis of alkyd (ALK) and polyesteramide (PEA) polyols. The prepared polyols were characterised by Fourier transform infrared and nuclear magnetic resonance techniques and size exclusion chromatography analysis. After reaction with diisocyanate, polyols were converted to polyurethane (PU) coatings, which were then characterised by X-ray diffraction, differential scanning calorimetry and thermogravimetric analysis. The biocidal activities of the films were evaluated against Gram-negative (Escherichia coli) and Gram-positive bacteria (Staphylococcus aureus) by using the turbidity method as well as by observation of film degradation or biofilm formation by bacteria on the surface of a metal tray by using scanning electron microscopy. The PUs obtained using ALK and PEA showed better antimicrobial properties compared with PUs based on algae oil fatty amide (AOFA), monoglyceride (MG) and even an uncoated mild steel (MS) panel. The anticorrosion properties of PU coatings were evaluated by the potential dynamic polarisation (PDP) method in a 3.5wt% sodium chloride (NaCl) corrosive media. All coated samples (ALK and PEA) showed good barrier properties against corrosion compared with AOFA, MG and the uncoated MS panel. The prepared algae-oil-based PU coatings showed better chemical, mechanical, water-repellent, antimicrobial, anticorrosive and thermal properties.

Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media, causing turnover rates to depend strongly on interfacial structure and composition, 142-25-6, Name is N1,N1,N2-Trimethylethane-1,2-diamine, SMILES is CNCCN(C)C, in an article , author is Liu, Qiufeng, once mentioned of 142-25-6, Application In Synthesis of N1,N1,N2-Trimethylethane-1,2-diamine.

The early stages of Alzheimer’s disease pathogenesis are thought to occur at the synapse level, since synapse loss can be directly correlated with memory dysfunction. Considerable evidence has suggested that amyloid beta (A beta), a secreted proteolytic derivative of amyloid precursor protein, appears to be a critical factor in the early ‘synaptic failure’ that is observed in Alzheimer’s disease pathogenesis. The identification of A beta at neuronal spines with high spatial resolution and high surface specificity would facilitate unraveling the intricate effect of A beta on synapse loss and its effect on neighboring neuronal connections. Here, tip-enhanced Raman spectroscopy was used to map the presence of A beta aggregations in the vicinity of the spines exposed to A beta preformed in vitro. Exposure to A beta was of 1 and 6 hours. The intensity variation of selected vibrational modes of A beta was mapped by TERS for different exposure times to A beta. Of interest, we discuss the distinct contributions of the amide modes from A beta that are enhanced by the TERS process and in particular the suppression of the amide I mode in the context of recently reported observations in the literature.

It has been shown that the inflammation associated with rheumatoid arthritis can be reduced using copper complexes. In order to improve the bioavailability of copper and hence efficacy, 3-(2-aminoacetamido)-N-(pyridin-2-ylmethyl)propanamide, H-2(5 6 5)NH2, was designed as a potential chelator of copper. Solution equilibrium measurements show that the [Cu(LH-2)] species predominates at physiological pH and blood plasma speciation calculations predict that this ligand is able to mobilise Cu(II) in vivo. A structural study of the Cu(II)/H-2(5 6 5)NH2 system was conducted in the solid and solution state using Uv-Vis, CD, H-1 NMR and EPR spectroscopy and single crystal X-ray crystallography. The result indicate that the structure of [Cu(H-2(5 6 5)NH2)H-2] in the solid and solution state are similar and confirm that, the metal binds to the pyridine nitrogen, the two amide nitrogens and the terminal amino group in a distorted square planar geometry.

Halide anion free hydrophilic Deep Eutectic Solvent (DES) based on choline dihydrogen citrate and urea (1:2 mol ratio) was prepared and successfully employed for dissolution of uranium compounds. Dissolution study was carried out with oxides viz. UO2, UO3 and crude yellow cakes viz. magnesium diuranate, sodium diuranate. Novel route of in-situ, single step eutectic solvent preparation and U compound dissolution was found to be promising in terms of better dissolution efficiency and process simplification. The resultant systems were probed with electrochemistry and UV-Vis spectrophotometry to get an insight about the uranium species. In all the four systems prepared by in-situ mode, stabilization of uranium in U(VI) oxidation state in the form of oxo species was indicated. This halide anion free eutectic system was amenable to be used in SC CO2 extraction set-up. SC CO2 extraction of uranium dissolved in eutectic solvent was found to be influenced by various extraction conditions viz. pressure, temperature, static and dynamic time. Uranium extraction efficiency of upto 65% for oxide system was achievable by SC CO2 modified with TTA.

A series of 7-O-amide hesperetin derivatives were subjected to multi-target biological evaluation of anti-Alzheimer’s disease. Most of the compounds showed good in vitro inhibitory activity against cholinesterase, of which compound 7c (7-O-(4-(morpholinoethyl)-acetamide) hesperetin) was the most effective anti-eqBuChE derivative (IC50 = 0.28 +/- 0.05 mu M) and exerted neuropmtective effects. Further biological evaluation found that compounds 4d, 4e and 7c showed strong antioxidant, anti-A beta self-aggregation and anti-neuroinflammatory activities. Compound 7c could inhibit the expression of iNOS and COX-2 proteins and prevent LPS-induced inflammatory response in BV2 cells. In addition, compound 7c could chelate biometal ions such as Cu2+ and Zn2+. In the vivo study, the MWM test confirmed that compound 7c could improve the cognitive impairment caused by scopolamine. In summary, the above studies have shown that the optimized compound 7c has great development potential as MTDL for the treatment of AD.

In this study, the soy protein was degraded and cross-linked with trimethylolpropane triglycidyl ether (THPTG) at 80 degrees C to prepare wood adhesive for interior plywood. Namely, by adding sodium hydroxide (NaOH), functional groups (-NH2, -COOH, and -OH) in soy protein were exposed and then reacted with epoxy groups to form a crosslinked water-resistance soy-protein adhesive under alkali condition. The optimum formulation of this adhesive was investigated. The molecular weights, chemical structure, bonding properties and water-resistance were characterized by gel permeation chromatography-multi-angle laser light scattering (GPC-MALLS), Fourier transform infrared spectroscopy (FTIR), plywood bonding test and three-cycle soak test. Results showed that at 2% NaOH, the molecular weight of soy protein isolate degradation (DSP) presented as 3.473e + 04 g center dot mol(-1) was homogeneous and resulted in greater increase of amide II and amide III. The cross-linking reaction between THPTG and DSP resulted in the increase of both viscosity and sensitivity of infrared absorption peaks of -O-H (3100 cm(-1)) and C-N (1190 cm(-1)). Also, the adhesives synthesized from the SPI denatured with 2% NaOH and 9% THPTG did meet the wet strength for interior-use plywood panels (>= 0.7 MPa) according to the China Industry Standard GB/T 9846.3-2004 and water resistance according to American National Standard for Hardwood and Decorative Plywood/Hardwood Plywood and Veneer Association.

Symmetric cell electrochemical impedance spectroscopy (SCEIS) is a powerful method to analyze electrode materials for secondary batteries. The EIS results are used to obtain information related to electrochemical processes such as charge-transfer resistance. In this study, SCEIS is employed to investigate the electrochemical performance of the Na2FeP2O7 positive electrode for sodium secondary batteries operating at temperatures ranging from room to intermediate temperatures using the ionic liquid (IL) electrolytes, Na[FSA]-[C(2)C(1)im][FSA] (ILFSA) (C(2)C(1)im = 1-ethyl-3-methylimidazolium, FSA = bis(fluorosulfonyl)amide). The obtained SCEIS result for Na metal, acetylene black, alpha-Al2O3, and V2O5 revealed that the resistance of the high-frequency region in the Nyquist plots is a combination of several factors (the Na[FSA] fraction, ionic conductivity of the electrolyte, and electronic conductivity of the composite electrode). The activation energies obtained by the Arrhenius plots for both the high-frequency and charge-transfer resistances of Na2FeP2O7/ILFSA/Na2FeP2O7 SCEIS showed that a significant decrease in the charge-transfer resistance contributes to the high rate performance in the intermediate temperature range.
