Collagen modified with epoxidized safrole for improving antibacterial activity

An epoxidized safrole, 5-(oxiran-2-ylmethyl)-benzo[d][1,3] dioxole (OYBD), was synthesized and employed to modify collagen for improving its antibacterial activity. The interaction between collagen and OYBD, and the structure/properties of the modified collagen were investigated in detail. The results indicated that the OYBD-modified collagen showed a higher de-nature temperature (Td, 90.2 degrees C), improved hydrophobic properties (contact angle from 84.2 degrees to 89.1 degrees) and enhanced tensile strength (6.2-11.0%) without destroying its triple helix structure. From observation of scanning electron microscopy (SEM), a higher density of intertwining morphology and a more stable network structure were observed, which was consistent with improved tensile strength and reduced breaking extension stress. The antibacterial test and LIVE/DEAD Baclight bacterial viability assay illustrated that the modified collagen exhibited excellent antibacterial activity to both Gram-negative and Gram-positive bacteria. Furthermore, the OYBD-modified collagen still exhibited cytocompatibility, supporting human fibroblast proliferation, which holds a great potential for developing antibacterial collagen-based biomaterials.

The role of lone pair and dipolar interactions in the non-planarity of 1,3-dioxolane and 1,3-dioxole

1,3-Dioxole has been shown to be non-planar by infrared and Raman spectroscopy. An MM3 study of this molecule enabled the investigators to suggest that this non-planarity was due to the anomeric effect. Subsequently, an ab initio theoretical study of this molecule was performed, which also concluded that the non-planarity of 1,3-dioxole was due to the anomeric effect and not to dipole-dipole interactions. Neither study used rigorous methods for assessing the role of dipolar interactions in the geometry of 1,3-dioxole. A new study of 1,3-dioxole, 1,3-dioxolane, tetrahydrofuran, cyclopentane, and some related molecules using the new QVBMM (molecular mechanics) force field shows conclusively that the non-planarity of 1,3-dioxole and 1,3-dioxolane is due primarily to torsional and dipolar effects, and not secondary molecular orbital overlap interactions.

High performance perfluoropolymer films and membranes

Membrane processes are receiving increasing attention in the scientific community and in industry because in many cases they offer a favorable alternative to processes that are not easy to achieve by conventional routes. In this context, membranes made with perfluorinated polymers are of particular interest because of the unique features demonstrated by these materials. Both highly hydrophobic and hydrophilic membranes have been developed from appropriate perfluoropolymers that were, in turn, obtained by copolymerizing TFE with special monomers available on an industrial scale. Highly hydrophobic membranes obtained from the glassy copolymers of TFE and 2,2,4-trifluoro-5 trifluoromethoxy-1,3 dioxole (Hyflon((R)) AD) exhibit properties that make them particularly well suited for use in optical applications, in the field of gas separation, and in gas-liquid contactors. Conditions for preparing membranes that are adequate for use in various applications are exemplified. Hydrophylic highly conductive proton exchange membranes obtained from the copolymer of TFE and a short-side-chain(SSC) perfluorosulfonylfluoridevinylether (Hyflon Ion) rind interesting application in the field of fuel cells, especially in view of the current tendency to move to high temperature operation. The advantages offered by these hydrophobic and hydrophylic perfluorinated materials for use in membrane technology are discussed. Comparison of membrane properties and performance is made with other membranes available on the market.

Study on the Electrical Conductive Mechanism in the Five-layered Structure of Organic Light-emitting Diodes

The Electrical conductive mechanism was studied using a five-layered structure of organic light-emitting diodes. The manufactured device structure was ITO/2,2-bistrifluoromethyl-4,5-difluoro-1,3-dioxole (AF)/N,N’-diphenyl-N,N’bis(3-methylphenyl)-1,1′-biphenyl-4,4′-diamine(TPD)/tris(8-hydroxyquinoline)aluminum (Alq(3))/(2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline (BCP)/LiF/Al. From the analysis of the current density-luminance-voltage characteristics of the five-layered device, four conductive mechanisms depending on the applied voltage region were found. In the Schottky region, where the electric field E is below 1.6 x 10(5) V/cm, the obtained Schottky coefficient beta(ST) is 3.98 x 10(-24) JV(-1/2)m(1/2). In the negative-resistance region, where the electric field is below 3.7 x 10(5) V/cm, the current density J is proportional to E(-2.41), In the Poole-Frenkel region, where the electric field is below 6.4 x 10(5) V/cm, the obtained Poole-Frenkel coefficient beta(P F) is 7.80 x 10(-24) JV(-1/2)m(1/2). The experiment obtained value of beta(P F) corresponds to 1.96 times that of beta(ST), which is theoretically expected because beta(P F) = 2 beta(ST). In the Folwer-Nordheim region, where the electric field is above 8.30 x 10(5) V/cm, the obtained potential barrier empty set(F N) is 0.42 eV.

Ruthenium-Catalyzed Asymmetric Hydrogenation of 3-Oxoglutaric Acid Derivatives: A Study of Unconventional Solvent and Substituent Effects

A series of 3-oxoglutaric acid derivatives have been hydrogenated in different solvents in the presence of [RuCl(benzene)(S)-SunPhos]Cl (SunPhos=(2,2,2′,2′-tetramethyl-[4,4′-bibenzo[d][1,3]dioxole]-5,5′-diyl)bis(diphenylphosphine)). Unlike simple beta-keto acid derivatives, these advanced analogues can be readily hydrogenated in uncommon solvents such as THF, CH2Cl2, acetone, and dioxane with high enantioselectivities. Two possible catalytic cycles have been proposed to explain the different reactivities of these 1,3,5-tricarbonyl substrates in the tested solvents. The C-2 and C-4 substituents had notable but irregular influence on the reactivity and enantioselectivity of the reactions. More pronounced solvent effects were observed: the ee values increased from around 20?% in EtOH or THF to 90?% in acetone. Inversion of the product configuration was observed when the solvent was changed from EtOH to THF or acetone, and a mixed solvent system can lead to better enantioselectivity than a single solvent.

Ryecyanatines A and B and ryecarbonitrilines A and B, substituted cyanatophenol, cyanatobenzo[1,3]dioxole, and benzo[1,3]dioxolecarbonitriles from rye (Secale cereale L.) root exudates: Novel metabolites with allelopathic activity on Orobanche seed germination and radicle growth

Orobanche and Phelipanche species (the broomrapes) are root parasitic plants, some of which represent serious weed problems causing heavy yield losses on important crops. Current control relies on the use of certain agronomic practices, resistant crop varieties, and herbicides, albeit success has been marginal. Agronomic practices such as the use of allelopathic species in intercropping or cover crops, or the use of direct seedling over residues of allelopathic species incorporate the principle of allelopathy exerted by molecules exuded from roots or released by crop residues to control broomrapes. In addition, the isolation of natural substances from root exudates of plants with potential to inhibit broomrape development opens the door to the design of new herbicides based on natural and benign sources. Ryecyanatines A and B and ryecarbonitrilines A and B, the first new substituted cyanatophenol, substituted cyanatobenzo[1,3]dioxole, and the latter two new substituted benzo[1,3]dioxolecarbonitriles were isolated from rye (Secale cereale L.) root exudates. They were characterized as 4-cyanato-2-methoxyphenol, 2-cyanato-benzo[1,3]dioxole, 2-methoxybenzo[1,3]dioxole-5-carbonitrile and benzo[1,3]dioxole-2-carbonitrile by spectroscopic (essentially NMR and HRESI MS spectra) methods. These compounds were investigated for allelopathic activity on Orobanche germination and development. Ryecarbonitriline A induced germination of Orobanche cumana seeds, and this germination can be considered as suicidal because O. cumana does not parasite rye roots and cannot survive without host resources beyond germination stage. In addition, ryecyanatine A promotes a rapid cessation of O. cumana, Orobanche crenata and Orobanche minor radicle growth with the promotion of a layer of papillae at the radicle tip in O. cumana and O. crenata hampering the contact of the parasite to the host. Ryecarbonitriline B also displayed the same activity although being less active than ryecyanatine A and mainly restricted to O. cumana. (C) 2014 Elsevier Ltd. All rights reserved.

Gas and vapor sorption and permeation in poly(2,2,4-trifluoro-5-trifluoromethoxy-1,3-dioxole-co-tetrafluoroethylene)

The solubilities of N-2, CO2, CH4, C2H6, C3H8, and C3F8 and permeabilities of N-2, O-2, CO2, CH4, C2H6, and C3H8 were determined in a glassy, amorphous fluoropolymer prepared from 80 mol % 2,2,4-trifluoro-5-trifluoromethoxy-1,3-dioxole (TTD) and 20 mol % tetrafluoroethylene (TFE), commercially known as Hyflon AD 80. This polymer exhibits lower increases in hydrocarbon gas and vapor solubility with increasing penetrant critical temperature than conventional hydrocarbon polymers. On the basis of a best fit of the natural logarithm of solubility vs critical temperature, Hyflon AD 80 should have much lower solubility for high molar mass hydrocarbon compounds (e.g., n-decane) than conventional hydrocarbon polymers. Pure gas CO2/CH4 separation properties of this polymer are comparable with those of some hydrocarbon polymers considered for natural gas purification. When exposed to a feed stream containing a mixture of CO2 and CH4, the polymer exhibits a CO2 permeability of approximately 250 barrers and a CO2/CH4 mixed-gas selectivity of 10.6 at 1.6 atm CO2 partial pressure. The mixed gas selectivity decreases minimally as CO2 partial pressure increases to 10.6 atm. The mixed gas selectivity is also maintained when moderate amounts of toluene and n-hexane are present in the CO2-CH4 feed stream. Diffusion coefficients, calculated from pure gas permeability and solubility coefficients, suggest membrane plasticization at higher pressures of CO2 and C2H6. The polymer also exhibits reversible hysteresis in C3H8 permeability with pressure.
