Dehydration of aprotic solvents, frequently needed in pharmaceutical processing, can be implemented easily by vacuum-based pervaporation employing a novel perfluoropolymer-based membrane: perfluoro-2,2-dimethyl-1,1,3-dioxole copolymerized with tetrafluoroethylene (PDD-TFE). Possessing one of the highest fractional free volumes, this polymer is resistant to most solvents including N,N-dimethyl formamide (DMF), N,N-dimethylsulfoxide (DMSO), and N,N-dimethylacetamide (DMAc). Results were obtained using a 25 mu m thick dense polymeric membrane supported by a porous polytetrafluoroethylene (PTFE) sheet. Maximum water flux values found for a 90 wt% aprotic solvent feed were as follows: 77 g/(m(2) h) for DMF-water mixture at 50 degrees C; 9.8 g/(m(2) h) for DMSO-water mixture at 30 degrees C; 9 g/(m(2) h) for DMAc-water mixture at 50 degrees C. Excellent pervaporation separation factors for water over these aprotic solvents were obtained for mixtures containing 1, 5 and 10 wt% water in the temperature range 30-60 degrees C. The separation factors varied between 1000 and 12,000 depending on the water content, temperature and the solvent species. Such highly selective water removal in pervaporation has been achieved earlier in dehydration of ethanol by NaA zeolite membranes which however achieve an order of magnitude lower selectivity in for example, DMF-water system.

BB-83698 is a first potent inhibitor of peptide deformylase in this novel class to enter clinical trials. In this study, automated docking, molecular dynamics simulation and binding free energy calculations with the linear interaction energy (LIE) method are first applied to investigate the binding of BB-83698 to the peptide deformylase from Bacillus stearothermophilus. The lowest docking energy structure from each cluster is selected as different representative binding modes. Compared with the experimental data, the results show that the binding of BB-83698 in Mode I is the most stable, with a binding free energy of -41.35 kJ/mol. The average structure of the Mode I complex suggests, that inhibitor interacts with Ilc59 and Gly109 by hydrogen bond interaction and with Pro47, Pro57, Ile59 and Leul46 by hydrophobic interaction are essential or the activity of BB-83698. Mode 2 represents a new binding mode. Additionally, if the hydrophilic group is introduced to the benzo-[1,3]-dioxole ring, the binding affinity of BB-83698 to the peptide deformylase from B. stearothermophilus will be greatly improved.

Researchers are common within chemical engineering and are often tasked with creating and developing new chemical techniques, frequently combining other advanced and emerging scientific areas. In an article, author is Meresi, G, once mentioned the application of 54623-25-5, Recommanded Product: 54623-25-5, Name is 2,3,5-Tri-O-benzyl-D-ribose, molecular formula is C26H28O5, molecular weight is 420.4975, MDL number is MFCD03425640, category is dioxole.

Pulse field gradient diffusion measurements of pentane in a random copolymer of tetrafluoroethylene (TFE) and 2,2-bis(trifluoromethyl)-4,5-difluoro-1,3-dioxole (PDD) were made as a function of the time allowed for diffusion to occur. The initial change in echo amplitude at low values of q = gamma deltag was used to determine the apparent diffusion constant. The apparent diffusion constant determined in this way decreases to a constant value as time increases. At a time of 12.4 ms the apparent diffusion constant was 2.2 x 10(-7) cm(2) s(-1), and it decreases to 5.87 x 10(-8) cm(2) s(-1) at 1 s. This change in the apparent diffusion constant was interpreted in terms of morphological structure on the micron length scale in this completely amorphous glassy polymer. This polymer has been considered to have high free volume regions which lead to the observed rapid permeation of gases and vapors. These regions are interspersed in lower free volume regions, and the low free volume regions constitute the majority component. In the pulse field gradient NMR experiment, regions allowing for rapid diffusion interspersed with regions allowing only slow diffusion can lead to changes in the apparent diffusion constant as a function of diffusion time. The data observed in this system were compared with two simple models for the topology of the regions allowing for rapid diffusion: restricted diffusion and tortuous diffusion. The observed behavior is qualitatively similar to tortuous diffusion and can be fit with an equation describing this type of diffusion.

The permeation and sorption of a few common organic solvents and separation of their mixtures through a polymeric membrane of perfluoro-2,2-dimethyl-1,1,3-dioxole copolymerized with tetrafluoroethylene (PDD-TFE) was investigated by vacuum-based pervaporation. Pure component permeations of common pharmaceutical solvents such as, toluene, methanol, ethyl acetate and tetrahydrofuran (THF), were carried out using a 25 mu m thick dense polymeric membrane supported by a porous polytetrafluoroethylene (PTFE) sheet. Overall permeability coefficients for these solvents along with those of aprotic solvents dimethylformamide (DMF) and dimethylacetamide (DMAc) determined earlier (Tang and Sirkar, 2012 [1]), plotted against their longest molecular diameters were correlated to yield a relationship between the molecular solvent size and their permeation through the membrane. The sorption of each pure solvent and a few of their mixtures were determined. Separation of a few organic-organic mixtures of these solvents was also implemented. These systems include: toluene-methanol, toluene-ethyl acetate and toluene-tetrahydrofuran. Modest separation factors were achieved using the PDD-TEE membrane unlike the very large values achieved earlier between water and aprotic solvents such as DMF, DMAc and DMSO (Tang and Sirkar, 2012 [1]). The maximum separation factor value for all systems was approximately 7.8 for a 75 wt% toluene and 25 wt % methanol feed at 30 degrees C. The separation factor obtained using a 50 wt% toluene and 50 wt% THF feed at 50 degrees C was close to 1. Maximum flux values through a 25 mu m thick PDD-TFE membrane were approximately 5 g/(m(2) h) for toluene ethyl acetate systems and 2.2 g/(m(2) h) for toluene-methanol and toluene-THE systems. The membrane was typically selective for the organic solvent with the smaller molecular dimensions. The solubility of the individual components in a mixture provided unique insights into such behavior. The observed separation behavior provides a window into the complex phenomena of organic solvent transport through the PDD-TFE membrane. (c) 2013 Elsevier B.V. All rights reserved.

Perfluorotetrahydro-2-methylene-furo[3,4-d][1,3]dioxole (monomer I) and perfluoro-2-methylene-4-methoxymethyl-1,3-dioxolane (monomer II) are soluble in perfluorinated or partially fluorinated solvents and readily polymerize in solution or in bulk when initiated by a free-radical initiator, perfluorodibenzoyl peroxide. The copolymerization parameters have been determined with in situ F-19 NMR measurements. The copolymerization reactivity ratios are r(I) = 1.80 and r(II) = 0.80 in 1,1,2-trichlorotrifluoroethane at 41 degrees C and r(I) = 0.97 and r(II) = 0.85 for the bulk polymerization. These data show that this copolymerization pair has a good copolymerization tendency and yields nearly ideal random copolymers. The copolymers have only one glass-transition temperature from 101 to 168 degrees C, depending on the copolymer compositions. Melting endotherms have not been observed in their differential scanning calorimetry traces, and this indicates that all the copolymers with different compositions are completely amorphous. These copolymers are thermally stable (the initial decomposition temperatures are higher than 350 degrees C under an N-2 atmosphere) and have low refractive indices and high optical transparency from UV to near-infrared. Copolymer films prepared by casting were flexible and tough. These properties make the copolymers ideal candidates as optical and electrical materials. (c) 2006 Wiley Periodicals, Inc.

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.
