Microwave-Assisted Syntheses in Recyclable Ionic Liquids: Photoresists Based on Renewable Resources

Petit, Charlotte,Luef, Klaus P.,Edler, Matthias,Griesser, Thomas,Kremsner, Jennifer M.,Stadler, Alexander,Grassl, Bruno,Reynaud, Stéphanie,Wiesbrock, Frank

, p. 3401 - 3404 (2015)

The copoly(2-oxazoline) pNonOx80-stat-pDc=Ox20 can be synthesized from the cationic ring-opening copolymerization of 2-nonyl-2-oxazoline NonOx and 2-dec-9′-enyl-2-oxazoline Dc=Ox in the ionic liquid n-hexyl methylimidazolium tetrafluoroborate under microwave irradiation in 250g/batch quantities. The polymer precipitates upon cooling, enabling easy recovery of the polymer and the ionic liquid. Both monomers can be obtained from fatty acids from renewable resources. pNonOx80-stat-pDc=Ox20 can be used as polymer in a photoresist (resolution of 1μm) based on UV-induced thiol-ene reactions.

KINETICS OF WET AIR OXIDATION OF DIETHANOLAMINE AND MORPHOLINE

Mishra, Vedprakash S.,Joshi, Jyeshtharaj B.,Mahajani, Vijaykumar V.

, p. 1601 - 1608 (1994)

The kinetics of Wet Air Oxidation of morpholine and diethanolamine (DEA) in aqueous solutions, were studied. The rates of destruction were measured with respect to reduction in substrate concentration and with respect to reduction in Chemical Oxygen Demand (COD). The studies were performed in the temperature range of 160 - 240 deg C and oxygen partial pressure was in the range of 0.34 - 1.36 MPa. The order with respect to COD and substrate concentration (morpholine and diethanolamine) was found to be one. Order with respect to oxygen concentration ranged from 0.3 to 0.9. The energy of activation was found to be in the range of 18.5 - 27.24 kcal/gmol. Monoethanolamine was found to be one of the intermediates formed during oxidation of morpholine and DEA. The mixtures of diethanolamine and morpholine were found to oxidize faster than that expected from the individual rate of oxidation. - Keywords: wastewater treatment; wet air oxidation; kinetics; morpholine; diethanolamine

Potential D,L-amino acid sequence analysis of peptides from the C-terminus

Ohrui,Itoh,Nishida,Horie,Meguro

, p. 392 - 395 (1997)

A model tripeptide, Gly-L-Leu-L-Phe, was immobilized with activated aminomethyl polystyrene, and its C-terminal was reduced to an alcohol. This peptidyl alcohol was selectively hydrolyzed at the C-terminal amide bond to afford a polymer-supported dipeptide (Gly-L-Leu) and amino alcohol (Phe-OH). The amino alcohol, including its absolute configuration, was determined by labelling with (+)-MNB-COOH, and the dipeptide was reused for a determination of its C-terminal amino acids. The D,L-amino acids of the tripeptide were sequentially determined from the C-terminus.

A high-throughput screening assay for amino acid decarboxylase activity

Medici, Rosario,De Maria, Pablo Dominguez,Otten, Linda G.,Straathof, Adrie J. J.

, p. 2369 - 2376 (2011)

The development of sensitive and easy-to-apply high-throughput screening methods is a common need in modern biocatalysis. With these powerful analytical tools in hands, chemists can easily assess enzyme libraries to identify either novel biocatalysts or improved mutants. Within biocatalysis, amino acid decarboxylases are gaining an increased importance, with several diverse applications ranging from the synthesis of bio-commodities to medical applications (e.g., synthesis of enzyme inhibitors at the level of L-DOPA decarboxylase). Herein, an efficient and simple analytical method for high-throughput screening of amino acid decarboxylase activity is reported. The method is valid for the discrimination of a broad range of amino acid/amine pairs such as L-tyrosine/tyramine, L-DOPA/dopamine, 5-hydroxy-L-tryptophan/ serotonin, L-histidine/histamine, L-serine/ethanolamine, L-tryptophan/ tryptamine, L-glutamic acid/GABA, and L-alanine/ethylamine. It has proven its versatility by using pure substrates, mixtures, or enzymatic reactions, both coming either from commercial enzymes or derived from cell-free (crude) extracts. The limit of detection was 13 μM for ethanolamine in the presence of 50 mM L-serine, while z′ values were in the range 0.75-0.93, indicating the suitability for high-throughput screening. Copyright

Kinetic and thermodynamic selectivity in subcomponent substitution

Schultz, David,Nitschke, Jonathan R.

, p. 3660 - 3665 (2007)

Within assemblies prepared by metal-templated imine condensation, one amine residue (subcomponent) may be replaced with another through substitution reactions. Proton transfer from a more to a less acidic amine may be used as the driving force for substitution. Herein, we detail the development of a set of selectivity rules to predict the outcome of subcomponent substitution reactions when several different substrates are present. When both iron and copper complexes were present, substitution occurred preferentially at imines bound to copper. This preference was kinetic in nature in the absence of a chelating amine subcomponent: The different amine residues were found to scramble between the copper and iron complexes following an initial clean substitution at the copper-bound imine. When both chelating and nonchelating amine subcomponents were present, the preference became thermodynamic in nature. Only the nonchelating amine was substituted and no evidence of scrambling was found after the reaction mixture was heated to 50°C for several days. This thermodynamic selectivity, based on the chelate effect, operated in mixtures of CuI and FeII complexes, and in systems containing only FeII complexes.

Enzymatic synthesis of 2-aminoethyl β-d-galactopyranoside catalyzed by Aspergillus oryzae β-galactosidase

Porciúncula González, Cecilia,Castilla, Agustín,Garófalo, Lucía,Soule, Silvia,Irazoqui, Gabriela,Giacomini, Cecilia

, p. 104 - 110 (2013)

Glycosidases provide a powerful resource for in vitro synthesis of novel anomerically pure glycosides. Generation of new low molecular weight galactosides is of interest since they are potential galectin inhibitors. Galectins are molecular targets for cancer therapy and thus their inhibitors are potential antitumor agents. Here we report the enzymatic synthesis and structural characterization of 2-aminoethyl β-d-galactopyranoside. Critical parameters for transgalactosylation using either soluble or immobilized enzyme were investigated and optimized for the galactoside synthesis. We found that 0.2 M lactose, and 0.5 M 2-aminoethanol at 50 °C for 30 min were the optimal conditions for synthesis. 2-Aminoethanol proved to be an enzyme inhibitor, fitting a mixed inhibition model with inhibition constants, Kic = 0.31 ± 0.04 M and Kiu = 0.604 ± 0.035 M.

Synthesis, molecular modeling and biological evaluation of metabolically stable analogues of the endogenous fatty acid amide palmitoylethanolamide

D’aloia, Alessia,Arrigoni, Federica,Tisi, Renata,Palmioli, Alessandro,Ceriani, Michela,Artusa, Valentina,Airoldi, Cristina,Zampella, Giuseppe,Costa, Barbara,Cipolla, Laura

, p. 1 - 25 (2020)

Palmitoylethanolamide (PEA) belongs to the class of N‐acylethanolamine and is an endogenous lipid potentially useful in a wide range of therapeutic areas; products containing PEA are licensed for use in humans as a nutraceutical, a food supplement, or food for medical purposes for its analgesic and anti‐inflammatory properties demonstrating efficacy and tolerability. However, the exogenously administered PEA is rapidly inactivated; in this process, fatty acid amide hydrolase (FAAH) plays a key role both in hepatic metabolism and in intracellular degradation. So, the aim of the present study was the design and synthesis of PEA analogues that are more resistant to FAAH-mediated hydrolysis. A small library of PEA analogues was designed and tested by molecular docking and density functional theory calculations to find the more stable analogue. The computational investigation identified RePEA as the best candidate in terms of both synthetic accessibility and metabolic stability to FAAH‐mediated hydrolysis. The selected compound was synthesized and assayed ex vivo to monitor FAAH‐mediated hydrolysis and to confirm its anti-inflammatory properties.1H‐NMR spectroscopy performed on membrane samples containing FAAH in integral membrane protein demonstrated that RePEA is not processed by FAAH, in contrast with PEA. Moreover, RePEA retains PEA’s ability to inhibit LPS‐induced cytokine release in both murine N9 microglial cells and human PMA‐THP‐1 cells.

Entropy effects in conformational distribution and conformationally dependent UV-induced photolysis of serine monomer isolated in solid argon

Jarmelo,Fausto

, p. 175 - 181 (2006)

Monomeric serine can be trapped in low temperature argon matrices in different conformers, which can be classified in three groups (A, B, C) accordingly to the main intramolecular interaction they exhibit: A (OHA?N hydrogen bond), B (OHC?N) and C (OHA?O{double bond, short}) (subscripts A and C stand for alcohol and carboxylic group, respectively). The OHC?N intramolecular interaction found in B-type conformers is considerably stronger than both the OHA?N and OHA?O{double bond, short} hydrogen bonds, and leads to reduce the abundance of B-type form relatively to A and C forms at high temperatures due to entropy effects. When submitted to UV irradiation (λ>200 nm), the main observed photoprocess is decarboxylation, leading to production of CO2 and ethanolamine. A less important photochemical process is also observed, where the compound undergoes decarbonylation, with formation of CO, H2O and acetamide. The two observed photoprocesses were found to be dependent on the conformation assumed by the reactant molecule, with A- and C-type conformers of serine undergoing decarboxylation and B-type conformers decarbonylation.

Synthesis, spectroscopic characterization, and in vitro antibacterial evaluation of novel functionalized sulfamidocarbonyloxyphosphonates

Bouzina, Abdeslem,Bechlem, Khaoula,Berredjem, Hajira,Belhani, Billel,Becheker, Imène,Lebreton, Jacques,Le Borgne, Marc,Bouaziz, Zouhair,Marminon, Christelle,Berredjem, Malika

, p. 1 - 14 (2018)

Several new sulfamidocarbonyloxyphosphonates were prepared in two steps, namely carbamoylation and sulfamoylation, by using chlorosulfonyl isocyanate (CSI), α-hydroxyphosphonates, and various amino derivatives and related (primary or secondary amines, β-amino esters, and oxazolidin-2-ones). All structures were confirmed by 1H, 13C, and 31P NMR spectroscopy, IR spectroscopy, and mass spectroscopy, as well as elemental analysis. Eight compounds were evaluated for their in vitro antibacterial activity against four reference bacteria including Gram-positive Staphylococcus aureus (ATCC 25923), and Gram-negative Escherichia coli (ATCC 25922), Klebsiella pneumonia (ATCC 700603), Pseudomonas aeruginosa (ATCC 27853), in addition to three clinical strains of each studied bacterial species. Compounds 1a–7a and 1b showed significant antibacterial activity compared to sulfamethoxazole/trimethoprim, the reference drug used in this study.

Kroutil, Jiri,Trnka, Tomas,Cerny, Miloslav

, p. 446 - 450 (2004)

The selective deprotection of N-benzyl group was achieved in the presence of azido, O-benzyl, and N-tosyl groups in reactions of benzylamines derived from 1,6-anhydro-β-D-glucopyranose with diisopropyl azodicarboxylate (DIAD) in THF. The key role of this solvent and the reaction pathway are presented together with proven reaction intermediates.

Research on hydroxyethyl ammonium O,O′-diphenyl dithiophosphate: Synthesis, characterization, surface activity and corrosion inhibition performance

Lai, Chuan,Xie, Bin,Guo, Xiaogang

, p. 107 - 114 (2020)

Hydroxyethyl ammonium O,O′-diphenyl dithiophosphate (HADD) acting as a surfactant and corrosion inhibitor was successfully synthesized and characterized by FT-IR, 1H NMR and single crystal X-ray diffraction. Meanwhile, the inhibition effect of HADD on Q235 steel (Q235s) corrosion in H2SO4 solution was studied by weight loss and potentiodynamic polarization measurements. HADD turned out to be an effective corrosion inhibitor and the inhibition efficiency increased with HADD concentration increasing, and significantly decreased with increasing both temperature and H2SO4 concentration. Potentiodynamic polarization measurements indicated that HADD was a mixed-type inhibitor.

Equilibrium constant for carbamate formation from monoethanolamine and its relationship with temperature

Haji-Sulaiman,Aroua,Benamor

, p. 887 - 891 (1999)

As carbamate formation is a problem in using monoethanolamine for removing CO2 and H2S from natural gas, the equilibrium constant (Keq) for carbamate formation from methanolamine was evaluated at 298, 303, 318, and 328 K, and ≤ 1.7 M ionic strengths. From the plot of the log Keq vs the square root of the ionic strength, a relationship of the variation of the thermodynamical constant with temperature was determined. A comparison with the values for diethanolamine carbamate showed that monoethanolamine carbamate is more stable and less temperature sensitive.

Copper(I) Phosphinooxazoline Complexes: Impact of the Ligand Substitution and Steric Demand on the Electrochemical and Photophysical Properties

Frey, Wolfgang,Giereth, Robin,Karnahl, Michael,Klo?, Marvin,Mengele, Alexander K.,Steffen, Andreas,Tschierlei, Stefanie

, p. 2675 - 2684 (2020/03/04)

A series of seven homoleptic CuI complexes based on hetero-bidentate P^N ligands was synthesized and comprehensively characterized. In order to study structure–property relationships, the type, size, number and configuration of substituents at the phosphinooxazoline (phox) ligands were systematically varied. To this end, a combination of X-ray diffraction, NMR spectroscopy, steady-state absorption and emission spectroscopy, time-resolved emission spectroscopy, quenching experiments and cyclic voltammetry was used to assess the photophysical and electrochemical properties. Furthermore, time-dependent density functional theory calculations were applied to also analyze the excited state structures and characteristics. Surprisingly, a strong dependency on the chirality of the respective P^N ligand was found, whereas the specific kind and size of the different substituents has only a minor impact on the properties in solution. Most importantly, all complexes except C3 are photostable in solution and show fully reversible redox processes. Sacrificial reductants were applied to demonstrate a successful electron transfer upon light irradiation. These properties render this class of photosensitizers as potential candidates for solar energy conversion issues.
