Gas permeation in poly(ether imide) nanocomposite membranes based on surface-treated silica. Part 1: Without chemical coupling to matrix

The long range objective of this research is to understand to what extent the presence of nanosized particles may change the local properties, and specifically perm selectivity characteristics, of a glassy polymer matrix or whether conventional composite theory can be applied to such composites, i.e., the matrix properties are not changed by the filler. In this work, nanocomposite membranes based on an amorphous, glassy poly(ether imide) were formed by incorporating three kinds of hydrophobically treated fumed silica by solution casting and melt processing techniques. However, there is considerable evidence that these nanocomposites contain voids or defects, probably at the polymer-particle interface or within aggregates, that increase gas permeability and decrease selectivity. Thus, the primary focus of this paper is the relation between the extent of voids formed in the nanocomposite and the permeation properties. In addition, this paper deals with techniques for dispersing nanosized particles, fumed silica, in the polymer matrix, characterization of morphology of this mixture using TEM and SEM, and evaluation of local properties based on gas permeation.

Chemical modification of Hyflon (R) AD copolymer end groups by means of physical and chemical treatments. A joint spectroscopic and quantum chemical investigation

In this paper is presented a study on the effects of physical treatments, namely electron beam irradiation or fluorination, on a perfluoropolymer copolymer of tetrafluoroethylene with 2,2,4-trifluoro-5-trifluoromethoxy-1,3-dioxole (Hyflon (R) AD copolymer). The analysis has been carried out by means of IR spectroscopy and quantum chemical modeling based on density functional theory; this combined experimental/ theoretical approach has proven effective for the interpretation of previously unassigned IR bands, which are associated to functional groups generated by polymer degradation and chain scission. We performed a systematic screening of chemical groups and structures compatible with degradation pathways that are possible from the chemical point of view: the chemical mechanisms and the correlation with the spectroscopic experimental data (both frequency and intensity) provide guidelines in understanding the phenomena. Moreover, the spectroscopic experimental/theoretical and chemical approaches allowed us to identify some chemical structures responsible for the unassigned IR bands in the C=O stretching frequency region above 1800 cm(-1), which is typical for carbonyl groups in fluorinated systems.

Antiatherosclerotic effects of small-molecular-weight compounds enhancing endothelial nitric-oxide synthase (eNOS) expression and preventing eNOS uncoupling

Many cardiovascular diseases are associated with reduced levels of bioactive nitric oxide ( NO) and an uncoupling of oxygen reduction from NO synthesis in endothelial NO synthase ( eNOS uncoupling). In human endothelial EA.hy 926 cells, two small-molecular-weight compounds with related structures, 4-fluoro-N-indan-2-yl-benzamide ( CAS no. 291756-32-6; empirical formula C16H14FNO; AVE9488) and 2,2-difluoro-benzo[1,3] dioxole-5-carboxylic acid indan-2-ylamide( CAS no. 450348-85-3; empirical formula C17H13F2NO3; AVE3085), enhanced eNOS promoter activity in a concentration-dependent manner; with the responsible cis-element localized within the proximal 263 base pairs of the promoter region. RNA interference-mediated knockdown of the transcription factor Sp1 significantly reduced the basal activity of eNOS promoter, but it did not prevent the transcription activation by the compounds. Enhanced transcription of eNOS by AVE9488 in primary human umbilical vein endothelial cells was associated with increased levels of eNOS mRNA and protein expression, as well as increased bradykinin-stimulated NO production. In both wild-type C57BL/6J mice and apolipoprotein E-knockout ( apoE-KO) mice, treatment with AVE9488 resulted in enhanced vascular eNOS expression. In apoE-KO mice, but not in eNOS-knockout mice, treatment with AVE9488 reduced cuff-induced neointima formation. A 12-week treatment with AVE9488 or AVE3085 reduced atherosclerotic plaque formation in apoE-KO mice, but not in apoE/eNOS-double knockout mice. Aortas from apoE-KO mice showed a significant generation of reactive oxygen species. This was partly prevented by nitric-oxide inhibitor N-omega- nitro-L-arginine methyl ester, indicating eNOS uncoupling. Treatment of mice with AVE9488 enhanced vascular content of the essential eNOS cofactor ( 6R)-5,6,7,8- tetrahydro-L-biopterin and reversed eNOS uncoupling. The combination of an up-regulated eNOS expression and a reversal of eNOS uncoupling is probably responsible for the observed vasoprotective properties of this new type of compounds.

Eco-sustainable synthesis and biological evaluation of 2-phenyl 1,3-benzodioxole derivatives as anticancer, DNA binding and antibacterial agents

The current research and development scenario in medicinal chemistry demands small molecules synthesized in a simple, fast and effective way with enhanced activity and fewer side effects than the existing ones. Therefore, one-pot, microwave assisted green and efficient synthesis of a series of derivatives belonging to 2-phenyl 1,3-benzodioxole (1a-14a) and 2-phenyl 1,3-benzo-dioxole-4-ol (1b-14b) class were carried out and subsequently investigated for their anticancer, antibacterial and DNA binding potential. Compound 3c proved to be the most active one among the screened derivatives possessing anticancer and antibacterial potency greater than the standard reference compound (cisplatin and cinoxacin for anticancer and antibacterial activity, respectively). The most active compound in terms of DNA binding capacity was found to be 5b. A rewarding feature of the work is a facile, convenient, eco friendly one step synthesis of compounds demonstrating attenuated activity against cancer and bacterial cell with an inherent potential of binding to DNA. Subsequently, a hit molecule for further anticancer, antibacterial (compound 3c) and DNA binding studies (compound 5b) was also identified. (C) 2014 King Saud University.

Two new stilbenods were isolated by repeat column chromatography and characterized: one is bibenzyl compound, 5-(2, 3-dimethoxyphenethyl)-6-methylbenzo [d] [1, 3] dioxole (1), and the other dibenz [b, f] oxepine, 10, 11-dihydro-2, 7-dimethoxy-3, 4-methylenedioxy dibenzo b, f] oxepine (2). Their structures were established on the basis of analyses of spectroscopic evidence, particularly by two-dimensional NMR spectroscopic analysis. Bibenzyl compound with a methyl group in the benzene ring is rarely found from natural sources. Natural oxepines are very rare, and most of them were reported to have good anti-tumor activities. In addition, anti-tumor activities of the new compounds were also evaluated. Among the compounds isolated, compound 2 showed anti-tumor activities with IC50 value of 47.2 mu g/mL in vitro against cultures of Hela cells.

Chain structure and stiffness of Teflon AF glassy amorphous fluoropolymers

The structure of the amorphous perfluorinated polymer Teflon AF 2400 and other structurally close perfluoropolymers was studied by means of a quantum chemistry method. The electronic and structural characteristics of the repeating unit and polymer models with ten and nine monomer units were obtained. It was found that two nonplanar isomers can exist for different models of the perfluorinated dioxole ring with a difference of their energy minimums of 10.8 kJ/mol. The orthogonal-block structure of the polymer chain of the perfluorodioxole homopolymer and its copolymer with tetrafluoroethylene was proposed, the block size was found, and a possible diameter of the void formed by two neighboring polymer chains was evaluated. Potential energy curves for the rotation of certain chain fragments about different bonds of the polymer main chain were constructed, and the polymer stiffness was shown to substantially depend on the molar ratio between perfluorodioxole and tetrafluoroethylene units in the copolymer and on the geometry of the perfluorodioxole ring.
