Oligospirothioketal (OSTK) rods are presented as an adjustable scaffold for optical membrane probes. The OSTK rods are readily incorporated into lipid bilayers due to their hydrophobic backbones. Because of their high length-over-diameter aspect ratio, only a minimal disturbance of the lipid bilayer is caused. OSTK rods show outstanding rigidity and allow defined labeling with fluorescent dyes, yielding full control of the orientation between the dye and OSTK skeleton. This. allows the construction of novel Forster resonance energy transfer probes with highly defined relative orientations of the transition dipole moments of the donor and acceptor dyes and makes the class of OSTK probes a power-fill, flexible toolbox for optical biosensing applications. Data on steady-state and time-resolved fluorescence experiments investigating the incorporation of coumarin- and [1,3]-dioxolo[4,5-f][1,3]benzo-dioxole-labeled OSTKs in large unilamellar vesicles are presented as a show case.

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.

New Advances in Chemical Research in 2021. Application In Synthesis of Disodium UDP-glucose, Chemistry involves the study of all things chemical – chemical processes, chemical compositions and chemical manipulation – in order to better understand the way in which materials are structured, how they change and how they react in certain situations. 28053-08-9, Name is Disodium UDP-glucose, SMILES is O[C@@H]1[C@@H](CO)O[C@@H]([C@@H]([C@H]1O)O)OP([O-])(OP([O-])(OC[C@H]2O[C@H]([C@@H]([C@@H]2O)O)N3C=CC(NC3=O)=O)=O)=O.[Na+].[Na+], belongs to dioxole compound.

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.

Molecular mutagens and carcinogens are structures which carry chemical and electronic properties that disturb and interact with the genomic machinery. Principally, a rule of thumb for carcinogens is that carcinogens are expected to introduce covalent irreversible bonding to one or several types of DNA bases, causing errors in the reading frame for the polymerases. 8-methoxy-6-nitrophenanthro[3,4-d][1,3]dioxole-5-carboxylic acid, better known as Aristolochic acid (AA1) is a recognized carcinogen which causes urotherial cancer and is found in certain plants. Its structure is particularly interesting given that it is closely related to phenanthrene in its polycyclic arrangement, and has four functional groups, a carboxyl-, a nitro-, a methoxy- and a dioxolane group. In this work, the structure of AA1 has been resolved at the MPWPW91 density functional theory method in combination with Aug-cc-pVDZ basis sets. A geometry analysis shows that in AA1 the carboxyl group’s torsion is caused by steric strain from the nitro group, which elevates the molecular plane of the first phenanthrene ring with 0.1 angstrom. The wavefunction analysis of AA1 shows that the ring deformation enhances a double -bond localization in the first ring, adjacent to the dioxalane group, and results in a decrease of ring aromaticity and induces a potentially frozen resonance. Intermolecular and intramolecular interactions were characterized by atoms in molecules and reduced density gradient analysis. This study brings novel information on the geometry and electronic structure of AA1, which are important for the further knowledge of its transformation in vivo and in situ.

There are many efforts for identification of natural compounds from dietary or medicinal plants. Young roots and aerial parts of A. persicus have been used as food additive or salad vegetable in some parts of Iran. In this study, different fractions of the root extract of A. persicus were subjected for isolation and purification of secondary metabolites. The methanol extract of the roots was fractionated with hexane (HE), chloroform (CL), ethyl acetate (EA) and methanol (ME). Five novel compounds were isolated from HE, CL and EA using different chromatographic techniques and were identified by H-1-NMR, C-13-NMR, 2D-NMR and MS spectroscopic methods. Elucidated compounds with benzodioxole structure were characterized for the first time as 5-((propanoyl methyl) amino)-4,7-dimethoxybenzo[d][1,3] dioxole (1), 5-(3-ethyloxiran-2-yloxy)-4,7-dimethoxybenzo[d][1,3] dioxole (2), 4,7-dimethoxy-5(propanonyl) benzo[d][1,3] dioxole (3), 4-ethoxybenzo[d][1,3] dioxol-6-carbaldehyde (4), and 4-(O-beta-D-glucopyranosyl)-6-(3-propanyloxiran-2-yloxy) benzo[d][1,3] dioxole (5).

Catechols are components of many metal-chelating compounds, including siderophores that are naturally occurring iron(III) chelators excreted by microorganisms. Catechol derivatives are poorly soluble in organic media and the synthesis of catechol-containing molecules requires the use of protected catechol precursors with improved organic solubility. We therefore developed 2,2-diphenyl-benzo[1,3]dioxole-4-carboxylic acid pentafluorophenyl ester. This activated ester reacts with an amine functionalized scaffold to generate chelators in which the catechol functions are protected in the form of diphenyl-benzodioxole moieties. The catechol can subsequently be deprotected, at the end of the synthesis, with trifluoroacetic acid (TFA). This strategy was applied to the synthesis of two catechol compounds functionalized with a terminal propargyl extension. These two compounds were shown to promote iron uptake in Escherichia coli and Pseudomonas aeruginosa. These two compounds are suitable for use as vectors in antibiotic Trojan horse approaches, as they could be conjugated with azide-functionalized antibiotics using the Huisgen dipolar 1,3-cycloaddition.
