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.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 526-95-4, in my other articles.

This work describes the preparation of a new modified electrode containing a ruthenium complex (cis-aquadimethylbipyridyltriphenylphosphineruthenium II), bonded to a stable polyphenol film. This modified electrode promotes the fast electrocatalytic oxidation of safrol (5-allyl-benzo[1,3]dioxole) and isosafrol (5-propenyl-benzo[1,3]dioxole), giving two interesting products benzo[1,3]dioxole-5-carbaldehyde (piperonal) and 3-benzo[1,3]dioxol-5-yl-propenal respectively, with good yields. The electrode preparation can be carried out at a potential range which does not interfere on the anchored electroactive ruthenium complex, but it allows for the phenol oxidation to occur and therefore polymerize forming the polyphenol film. The catalytic character of this modified electrode is showed by its high turnover numbers. The procedure to isolate the products is very simple. (c) 2006 Elsevier Ltd. 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.

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.

Synthetic Route of 106-91-2106-91-2, Name is Oxiran-2-ylmethyl methacrylate, SMILES is CC(C(OCC1OC1)=O)=C, belongs to dioxole compound.

Spectra of xenon-129 sorbed into two high permeability polymers are reported. The polymers are the copolymer of tetrafluoroethylene and 2,2-bis(trifluoromethyl)-4,5-difluoro-1,3-dioxole as well as poly(1-trimethylsilyl-1-propyne). At room temperature, the xenon-129 shifts are smaller than in conventional glassy polymers. The smaller xenon-129 shift indicates the presence of larger sorption sites in high permeability polymers relative to conventional polymers. The temperature dependence of solubility in these polymers is drastically different from the behavior in conventional polymers. There is a rapid exponential increase in solubility in high permeability polymers as temperature decreases corresponding to a large negative enthalpy change on sorption and it is this increase in solubility which leads to a large increase in shift with decreasing temperature. Pulse field gradient (PFG) determinations of the self-diffusion constant are made for xenon, propane, pentane and a decafluoropentane in the copolymer. Rapid diffusion is observed as well as a dependence of the apparent diffusion constant on the time scale of the PFG experiment. The translational mobility of smaller simpler moieties depends less on the time scale or equivalently, the length scale of observation in the PFG NMR experiment. For larger, more complex species, the interconnectedness of high free volume domains plays a role in reducing the apparent diffusion constant as the time of measurement increases.
