"A Comparative Cytotoxic Evaluation of Acrylamide and Diacetone Acrylamide to Investigate Their Suitability for Holographic Photopolymer Formulations."

Abstract:

The comparative cytotoxic evaluation of two monomers, diacetone acrylamide (DA) and acrylamide (AA) used in holographic photopolymer formulations, is reported. Two normal cell lines were used: BEAS-2B and HaCaT. Cellular viability was assessed using the MTT assay for three different exposure times. A difference of two orders of magnitude is observed in the lethal dose (LD50) concentrations of the two monomers. Diacetone acrylamide exhibits a significantly lower toxicity profile in comparison to acrylamide at all exposure times. This result justifies the replacement of acrylamide with diacetone acrylamide in the photopolymer formulation, with the view to reducing occupational hazard risks for large-scale holographic device fabrication. A comparative study investigating the holographic recording ability of the two photopolymers in transmission mode showed that the DA photopolymer is capable of reaching refractive index modulation values of3.3×10-3, which is 80% of the refractive index modulation achieved by the AA photopolymer. This makes the DA-based photopolymers suitable for a wide range of applications.

Abstract:

An investigation of the structures of isomeric ions formed in ion/molecule reactions occurring in 2-propanone (acetone), 4-hydroxy-4-mefhyl-2-pentanone (diacetone alcohol), and 4-methyl-3-penten-2-one (mesityl oxide) has been performed using a hybrid mass spectrometer of reversed geometry. Ions of m/z 117, which have been observed as products of ion/molecule reactions in acetone and in diacetone alcohol, may have a single structure if an aldol type condensation reaction occurs under acidic conditions in the gas phase; however, high energy collision induced dissociation (CID) results proved the two ions to be isomeric only.Dehydration of the m/z 117 ions produced a species of m/z 99 which, in the case of diacetone alcohol, may have the structure of protonated mesityl oxide. That the m/z 99 ion formed was unique to each system was demonstrated by high energy CID and kinetic energy release (KER) spectrometry. In the acetone system, CID results suggested that m/z 99 was an ion–dipole complex of [Formula: see text]; this hypothesis was tested by clustering [Formula: see text]with (CD3)2CO and comparison of its CID results with those obtained above. In the case of m/z 99 derived from diacetone alcohol or mesityl oxide, the neutral lost via metastable decomposition in the second field-free region was found to be C4H8, presumably 2-methyl propene. While the ion of m/z 99 may also eliminate methane to yield a species of m/z 83, the dominant metastable elimination from this ion is carbon monoxide rather than ethene as shown by collision induced dissociative ionization (CIDI). The ions of m/z 83 observed in the two systems exhibit very similar CID spectra; however, a small variation in the yield of products of m/z 41 and 43 suggests two structures for the ion derived from diacetone alcohol, one of which is identical to that seen in mesityl oxide.

Abstract:

A novel solid base catalyst, structured MgO/Al2O3-Al catalyst packing, was prepared by supporting MgO onto a thin film of alumina that was formed by anodic oxidation of high purity aluminium foils. Some preparation parameters including the molar ratio of Mg(NO3)2•6H2O to CH3(CH2)16COOH, the aging time, the calcination temperature and time were investigated by using the catalyst for the condensation of acetone to diacetone alcohol. Each of those factors had some influence on the catalyst activity and an optimum value was obtained. The conversion of acetone was 20.2%, and the selectivity to diacetone alcohol was 100% under the optimized preparation conditions.

Abstract:

Paper reports the results of landfill leachate treatment with membrane bioreactor, nanofiltration and ozonation. Investigated leachate encompasses a number of specific compounds of pharmaceutical origin, including a suite of by-products deriving from the production of vitamin C and propyphenazone. Low biodegradability was observed in MBR (16%) for propyphenazone, while the removal of intermediates from the vitamin C-synthesis was moderate, reaching 30% for diacetone sorbose (DAS) and 69% for diacetone alpha-keto-gulonic acid (DAG). Ozonation almost completely removed propyphenazone but failed to significantly oxidise intermediates from the vitamin C-synthesis. Nanofiltration of the leachate succeeded to remove 99% of DAG and 79% of propyphenazone which made it the most efficient among techniques used.

Abstract:

Fourteen Lactococcus lactis strains showing inhibitory activity against Listeria innocua SICC 4202 were isolated from different French raw milks and raw milk cheeses and screened for bacteriocin production by the triple layer method under conditions that eliminate the effects of lactic acid and hydrogen peroxide. Three bacteriocinogenic strains (two Lactococcus lactis subsp. lactis bv. diacetylactis UL719 and UL720 and one Lactococcus lactis subsp. lactis UL730) were selected for their high capacity to inhibit the growth of various food pathogens, including Listeria monocytogenes, Staphylococcus aureus, and clostridial strains. The inhibitory compounds from these three strains are inactivated by selected proteases, indicating their protein nature. They retained their antibacterial activity after heat treatments of 100 °C for 60 min and 121 °C for 20 min, and in the pH range from 2 to 11. The bacteriocin diacetin B produced by strain UL720 has been purified by a pH-dependent adsorption–desorption procedure, followed by reverse-phase high performance liquid chromatography, with a yield of 1.25% of the original activity. Mass spectrometry analysis indicates that the pure peptide has a molecular mass of 4292.32 or 4490.28 Da, while amino acid sequencing allowed the identification of the primary structure of the bacteriocin composed of 37 amino acid residues. The structure of the peptide did not show similarity with other known bacteriocins from lactic acid bacteria.Key words: isolation, Lactococcus lactis subsp. lactis bv. diacetylactis, bacteriocin, diacetin B, purification.

Full text

Abstract:

To exploit the hydrolytic activity and high selectivity of immobilized lipase B from Candida antarctica on octyl agarose (CALB-OC) in the hydrolysis of triacetin and also to produce new value-added compounds from glycerol, this work describes a chemoenzymatic methodology for the synthesis of the new dimeric glycerol ester 3-((2,3-diacetoxypropanoyl)oxy)propane-1,2-diyl diacetate. According to this approach, triacetin was regioselectively hydrolyzed to 1,2-diacetin with CALB-OC. The diglyceride product was subsequently oxidized with pyridinium chlorochromate (PCC) and a dimeric ester was isolated as the only product. It was found that the medium acidity during the PCC treatment and a high 1,2-diacetin concentration favored the formation of the ester. The synthesized compounds were characterized using IR, MS, HR-MS, and NMR techniques. The obtained dimeric ester was evaluated at 100 ppm against seven bacterial strains and two Candida species to identify its antimicrobial activity. The compound has no inhibitory activity against the bacterial strains used but decreased C. albicans and C. parapsilosis growth by 49% and 68%, respectively. Hemolytic activity was evaluated, and the results obtained support the use of the dimeric ester to control C. albicans and C. parapsilosis growth in non-intravenous applications because the compound shows hemolytic activity.

Full text

Abstract:

A series of polypyrrole supported WO3were fabricated and characterized by FT-IR, XRD, XPS, BET, TGA, and FESEM-EDX. The activity of the catalysts was tested in glycerol esterification with acetic acid, and it found that WO3-Ppy-20 (nanocomposite with 20% WO3loaded) showed the maximum catalyst activity with 98% and selectivity of 70% to triacetin at 110°C with a reaction duration of 10 h and also recorded the highest selectivity (75%) for acetylation of glycerol to monoacetin with about 59% conversion only. The highest acidity of WO3-Ppy-20 is also confirmed using TPD-NH3analysis. The activity and selectivity to triacetin of the catalyst were enhanced by increasing WO3loading amount, resulting in 82% conversion for WO3-Ppy-5 with about 32 and 50% selectivity to monoacetin and diacetin and about 18% selectivity to triacetin; in case of WO3-Ppy-20, these amounts were changed to 5, 25, and 70% selectivity to monoacetin, diacetin, and triacetin, respectively with the conversion of 98%. TPD-NH3analysis found that polypyrrole supported WO3increases the catalyst acidity of WO3. BET and FESEM analyses revealed that WO3particles were well dispersed with the smallest average size in nanocomposite compared to pure WO3, which could contribute to the high activity of WO3-Ppy catalyst for esterification of glycerol.

Full text

Abstract:

Two synthetic approaches for the synthesis of N,N′-di(2-hydroxybenzyl)ethylenediamine-N,N′-diacetic acid (HBED) and derivatives are reported. The first involves conversion of N,N′-di(2-hydroxybenzyl)ethylenediamine to the diamide HBEDDA via reaction with formaldehyde and HCN followed by hydrolysis. Analysis of the species distribution curves of the Cu(II) chelates of N,N′-di(2-hydroxybenzyl)ethylenediamine-N,N′-diacetic acid (HBED) and its diamide, HBEDDA, and of the nature of the coordination in each complex species formed, suggest the selection of the reaction conditions most favorable for the Cu(II)-catalyzed hydrolysis of HBEDDA to HBED. The rate of conversion was found to be low, and the reasons for these findings are described. Iron(III) catalysis of the conversion of HBEDDA to HBED was found to be rapid and complete with a pseudo-first-order rate constant of 3.1 × 10−3 s−1 at 25.0 °C. The results provide the final step of a new method for the synthesis of HBED. The second synthetic approach involves reaction of N,N′-ethylenediamine-diacetic acid (EDDA) with substituted phenols and formaldehyde. These approaches appear to be general for the synthesis of HBED and derivatives.

Abstract:

Abstract The (μ-oxo)(μ-carbonato)diiron(III) complex with H2(tfda) (H2(tfda) = 2-aminomethyl-tetrahydrofuran-N,N-diacetic acid) exhibited high activity for hydroxylation of 2′-deoxygua-nosine in the presence of hydrogen peroxide, giving 8-hydroxydeoxyguanosine, but its hy droxylation activity towards other nucleosides such as 2′-deoxyadenosine, adenosine or thym idine was found negligible. In the case of the Fe(III)-(ed a) complex (H2(eda) = 2-methoxyethylamine-N,N-diacetic acid), hydroxylation occurred mainly at the sugar site, converting 2′-deoxyguanosine to guanosine. Based on the spectroscopic and structural properties of these iron(III) compounds, it seems most likely that an intrinsic active species for hydroxylation should be an electrophilic peroxide adduct of the (μ-oxo)diiron(III) core with η1 coordination mode, while the contribution of OH· sides is ruled out.

Both enantiomers of 1,3,5-trisubstituted hydantoins were conveniently synthesized through a dynamic kinetic resolution of bromoacetates derived from either ethyl l-lactate or diacetone-d-glucose. The sequential three-component reaction permitted the preparation of (R)- or (S)-1,3,5-trisubstituted hydantoins in yields of 77–51% with enantiomeric ratios of up to 95:5.

Abstract:

Imidacloprid is a neonicotinoids insecticide, which is important for the cash crops such as tomato, rape and so on. The conventional formulation does not only increase the loss of pesticide but also leads to environmental pollution. Controlled-release formulations of pesticide are highly desirable not only for attaining the most effective utilization of the pesticide, but also for reducing environmental pollution. Pesticide imidacloprid was incorporated in poly (styrene–diacetone crylamide)-based formulation to obtain controlled release properties, and the imidacloprid nanocontrolled release formulation was characterized by infrared (IR) and field emission scanning electron microscope (FESEM). Factors related to loading efficiency, swelling and release behaviors of the formulation were investigated. It showed that the loading efficiency could reach about 40% (w/w). The values for the diffusion exponent "n" were in the range of 0.31–0.58, which indicated that the release of imidacloprid was diffusion-controlled. The time taken for 50% of the active ingredient to be released into water, T50, was also calculated for the comparison of formulations in different conditions. The results showed that the formulation with higher temperature and more diacetone crylamide had lower value of T50, which means a quicker release of the active ingredient. This study highlighted some pieces of evidence that improved pesticide incorporation and slower release were linked to potential interactions between the pesticide and the polymer.

Abstract:

The asymmetric synthesis of gymnastatin H has been achieved by using the photoisomerisation of a conjugated ester to its β,γ-unsaturated isomer through the protonation of a in situ generated dienol as key step. Thanks to diacetone D-glucose used as a chiral alkoxy group, the protonation occurred well onto one of the two diastereotopic faces with very high yields and selectivities. Moreover, by this way the configuration of the C-6 centre of the target molecule was controlled.

Abstract:

Living radical polymerization of 3-O-methacryloyl-diaceton-D-glucose was carried out by the atom transfer radical polymerization (ATRP) method with an alkyl halide/copper-complex system. The effect of initiators, catalysts, ligand, and temperature on polymerization was studied in detail. Under the optimum condition, the time-conversion first-order plot was linear and the polydispersity of giycopolymer is relatively low, indicating that the polymerization is well controlled.

Abstract:

Two dansyl-modified β-cyclodextrin derivatives ( 1 and 2 ) have been synthesized as host–guest sensory systems for the direct fluorescent detection of the peroxide explosives diacetone diperoxide (DADP) and triacetone triperoxide (TATP) in aqueous media. The sensing is based on the displacement of the dansyl moiety from the cavity of the cyclodextrin by the peroxide guest resulting in a decrease of the intensity of the fluorescence of the dye. Both systems showed similar fluorescent responses and were more sensitive towards TATP than DADP.
