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.

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.

As an amide fungicide, fenhexamid has been extensively used to control botrytis and sderotinia as well as antagonize the resistant bacteria produced by other pesticides. But because of the accumulation of residues in fruit and vegetable products, it may have an adverse effect on the health of human and animals. In this work, the exploration of the interaction between fenhexamid and calf thymus DNA (ct-DNA) was carried out by fluorescence spectroscopy, IJV-vis spectroscopy, circular dichroism, viscosity measurement, melting measurements, molecular docking and molecular dynamics simulation. The results implied that fenhexamid bound onto ct-DNA in terms of groove binding. And the outcomes from circular dichroism measurements demonstrated a slight change in the ct-DNA helical structure during the binding process. In addition, the combination ratio of fenhexamid with ct-DNA was 1:1 and the association constant was 2.52 x 10(3) M-1 at 298 K. The measured thermodynamic parameters indicated that hydrogen bonding interaction and van der Waals forces become more dominant during interacting fenhexamid with ct-DNA, which was further confirmed through computer simulation technique.

An investigation into the effect of switching methoxy and hydroxyl groups on molecular salts is presented in this study. The salts HL1+center dot NO3- (1), L-1 center dot HL1+center dot ClO4- (2), L-1 center dot HL1+center dot H2PO4-center dot H2O(3), HL2+center dot NO3- (4), HL2+center dot ClO4- (5) and HL2+center dot H2PO4- (6) were synthesized and structurally characterized. The study was carried out by analyzing the crystal structure, properties and intermolecular interactions within each of the salts using IR and fluorescence spectra, TGA, Hirshfeld surface analyses and pi center dot center dot center dot pi stacking motifs. Salt 1 has a layered structure, while 4 has a distorted 3-D structure. Salt 2 possesses an edge-to-face type plane interaction, while 5 is formed with a twisted structure. It is important to note that water molecules play a key role in the 1-D chain structure of salt 3. The pi center dot center dot center dot pi stacking motif of salts 1-3 have a herringbone structure, while salts 3-6 exhibit a g-structure. In addition, the competitive crystallization of the synthetic salts was investigated and found to be consistent with the measured solubility.

There is controversy concerning the role of dihydroceramide desaturase (Degs1) in regulating cell survival, with studies showing that it can both promote and protect against apoptosis. We have therefore investigated the molecular basis for these opposing roles of Degs1. Treatment of HEK293T cells with the sphingosine kinase inhibitor SKi [2-(p-hydroxyanilino)-4-(p-chlorophenyl)thiazole) or fenretinide, but not the Degs1 C) inhibitor GT11 IN-PR,2S)-2-hydroxy-1-hydroxymethyl-2-(2-tridecyl-1-cyclopropenyfiethyl]octan-amide), induced the polyubiquitination of Degs1 (M-r = 40 to 140 kDa) via a mechanism involving oxidative stress, p38 mitogen-activated protein kinase (MAPK), and Mdm2 (E3 ligase). The polyubiquitinated forms of Degs1 exhibit gain of function and activate prosurvival pathways, p38 MAPK, c-Jun N-terminal kinase (JNK), and X-box protein 1s (XBP-1s). In contrast, another sphingosine kinase inhibitor, ABC294640 [344- chlorophenyl)-adamantane-1-carboxylic acid (pyridin-4-ylmethyl)amide), at concentrations of 25 to 50 mu M failed to induce formation of the polyubiquitinated forms of Degs1. In contrast to SKi, ABC294640 (25 mu M) promotes apoptosis of HEK293T cells via a Degs1-dependent mechanism that is associated with increased de novo synthesis of ceramide. These findings are the first to demonstrate that the polyubiquitination of Degs1 appears to change its function from proapoptotic to prosurvival. Thus, polyubiquitination of Degs1 might provide an explanation for the reported opposing functions of this enzyme in cell survival/apoptosis.

Understanding the factors that influence ion-solvent properties for the fluoride ion in organic solvents is key to the development of useful liquid electrolytes for fluoride-ion batteries. Using both experimental and computational methods, we examined a range of chemical and electrochemical properties for a set of organic solvents in combination with dry N,N,N-trimethylneopentylammonium fluoride (Np1F) salt. Results showed that solvent electronic structure strongly influences Np1F dissolution, and the pK(a) of solvent protons provides a good guide to potential F- reactivity. We found a number of organic solvents capable of dissolving Np1F while providing chemically-stable F- in solution and characterized three of them in detail: propionitrile (PN), 2,6-difluoropyridine (2,6-DFP), and bis(2,2,2-trifluoroethyl) ether (BTFE). Arrhenius analysis for Np1F/PN, Np1F/DFP, and Np1F/BTFE electrolytes suggests that DFP facilitates the highest F- ion mobility of the three neat solvents. Electrolyte mixtures of BTFE and amide co-solvents exhibit higher ionic conductivity than the neat solvents. This improved ionic conductivity is attributed to the ability of BTFE:co-solvent mixtures to partition between Np-1(+) and F- ion-aggregates, promoting better ion dissociation.

Application of 1492-24-6, Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, 1492-24-6, Name is H-Abu-OH, SMILES is CC[C@H](N)C(O)=O, belongs to amides-buliding-blocks compound. In a article, author is Guo, Lin-E, introduce new discover of the category.

Mass-selective two-color resonant two-photon ionization (2C-R2PI), UV/UV hole-burning, and infrared (IR) depletion spectra of supersonic jet-cooled 2-pyridone center dot(H2O)(n) clusters with n = 1-4 have been measured to investigate the local hydration patterns around 2-pyridone (2PY) as a function of cluster size. As shown by others, the IR frequencies of the OH and NH stretches of the n = 1, 2 clusters are characteristic of water wires stretching from the NH to the C=O group of 2PY. We identify two isomers (3A and 3B) of the n = 3 cluster in the 2C-R2PI spectrum and separate them by IR/UV and UV/UV hole-burning techniques. Isomer 3A exhibits a three-membered water wire, extending the n = 1, 2 structural motif. Isomer 3B exhibits bifurcated water wires with the first H2O donating to two waters that form H-bonds to the C=O group. This increases the H-bond strength between the NH group of 2PY and the proximal H2O molecule, lowering the NH stretch to similar to 2800 cm(-1) The n = 4 cluster is also bifurcated with two water wires between the bifurcating H2O and the C=O group. The cluster-selective IR spectra are complemented with density-functional calculations using the PW91, B3LYP, B97-D, and M06-2X functionals, where the latter two include long-range dispersive interactions, and with the ab initio correlated SCS-CC2 method. The calculated IR spectra provide firm assignments of the structures of the n = 1-4 cluster structures and allow us to understand the evolution of individual H-bond strengths with increasing cluster size.
