The spin probe technique was systematically applied to study a family of high permeability and high free volume glassy polymers. Rotation correlation times tau(c) Or frequencies nu = 1/tau(c) of 2,2,6,6-tetramethylpyperidine-1-oxyl (TEMPO) were measured in amorphous teflons – random copolymers of tetrafluoroethylene and 2,2-bistrifluoromethyle-4,5-difluoro-1,3-dioxole, polyacetylenes and polynorbornenes. Polymers distinguished by unusually high, for the glassy state, permeability and free volume exhibit large rotational mobility of TEMPO. The correlation times correspond to fast rotation of the spin probe previously observed only in rubbery polymers, Correlations between the frequency nu and gas permeability and diffusion coefficients were observed. However, in some polymers, the spin probe’s rotation rate is also sensitive to side-chain local mobility, which does not affect translational diffusion coefficients of gas molecules in polymers.

A new method is being proposed for preparing MALDI target plates with a hydrophobic polymer coating and hydrophilic anchors The particles of the MALDI matrix were pre-mixed with a poly[4 5-chfluoro-2 2-bis(trifluoromethyl)-1 3-dioxole-co-tetrafluoroethylene] solution prior to their placement on a mass-spectrometric sample support This technique led to the formation of matrix microspots with a diameter of less than 1 mm inside the polymer The polymer and matrix concentration as well as the amount of suspension placed on the target plate influenced the size and quality of microspots to a great extent The sensitivity of the mass-spectrometric analysis was confirmed by obtaining the mass spectra of fmole concentrations of an apomyoglobin tryptic digest The potential proteomic application of this type of MALDI surface preparation was demonstrated by performing the redox cycle using glutathione and its analogue All reactions were carried out directly on a MALDI plate which accommodates low volumes of reagents and prevents sample loss (C) 2010 Elsevier B V All rights reserved

Pruinosanone A (1), a novel spirochromone, was isolated from the roots of Caragana pruinosa. Two biogenetically related isoflavone intermediates, pruinosanones B and C (2 and 3), were also isolated, together with five known analogs identified as 3-hydroxy-9-methoxypterocarpan (4), 7,2′-dihydroxy-4′-methoxyisoflavanol (5), retusin-8-methylether (6), 7,2′-dihydroxy-8,4′-dimethoxy isoflavone (7) and 7,3′-dihydroxy-8,4′-dimethoxy isoflavone (8). The structures of 1-3 were elucidated based on extensive spectroscopic methods. Notably, 1 is the first example of a spirochromone possessing an unprecedented pentacyclic skeleton containing a spiro[benzo[d][1,3] dioxole-2,3′-chroman]-4′-one motif, which was confirmed by X-ray diffraction analysis. A plausible biosynthetic pathway for 1 was also proposed. Compounds 1-8 were tested for their ability to inhibit nitric oxide (NO) production in LPS-induced RAW 264.7 macrophages, and compounds 1-3 were the most potent inhibitors of NO production, with IC50 values of 1.96, 1.93 and 1.58 mu M, respectively. A structure-activity relationship analysis revealed that the fused 2-isopropenyl-2,3-dihydrofuran moiety plays a vital role in the potency of these compounds. Moreover, 1 was found to significantly inhibit inducible nitric oxide synthase (iNOS) protein expression, which accounts for the potent inhibition of NO production by this spirochromone.

Both the traditional Chinese medicinal fungus, Antrodia camphorata, and its secondary metabolite, 4,7-dimethoxy-5-methylbenzo[d] [1,3]dioxole, have been reported to possess promising anticancer activity. In this work the natural product and analogues bearing more polar substituents were synthesised and assessed for antiproliferative activity in the NCI-60 screen. Although each compound inhibited the growth of some cell lines at 10 mu M, none had sufficient activity to warrant further investigation.

A series of novel thiazole Schiff base derivatives containing benzo[d][1,3] dioxole moiety was designed, synthesized and screened for their fungicidal activities. The preliminary results demonstrated that compounds 6p, 6q and 6r possessed potent activities against Phytophthora infestans, Pyricularia oryzae and Septoria tritici in vitro. Compounds 6d and 6r exhibited remarkable activities against Botrytis cinerea(whole plant) and Phytophthora infestans(leaf disk) respectively in vivo, which were identified as the most promising candidates for further study and could be used as possible lead compounds for developing new fungicides.

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.

Peroxidic perfluoropolyethers (PFPEs) are industrial intermediates used by Solvay Solexis for the preparation of different classes of (per)fluoropolyethers (Fomblin (R), Galden (R), Solvera (R), Fluorolink (R)). The chemistry of these peroxidic compounds has been recently exploited for the synthesis of novel PFPE block copolymers. In the present work we report the synthesis, the structural and physical-chemical characterization of block copolymers obtained by the reaction of peroxidic PFPEs with 2,2,4-trifluoro-5-trifluoromethoxy-1,3-dioxole, a cyclic homopolymerizable perfluoroolefin. These block copolymers combine the most attractive properties of the PFPEs, like the excellent lubrication, the high thermal stability and the optical transparency, with new specific properties which are related to the perfluorodioxolenic blocks.
