Collagen modified with epoxidized safrole for improving antibacterial activity

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.

Effect of 5-{3-[((2S)-1,4-benzodioxan-2-ylmethyl)amino]propoxy}-1,3-benzodioxole HCl (MKC-242), a novel 5-HT1A-receptor agonist, on aggressive behavior and marble burying behavior in mice

Behavioral effects of 5-{3-[((2S)-1,4-benzodioxan-2ymethyl)amino]propoxy}-1,3-benzo- dioxole HCI (MKC-242), a novel 5-HT1A-receptor agonist, were evaluated using animal models of anxiety and obsessive compulsive disorder and compared against reference compounds. MKC-242 suppressed foot shock-induced fighting behavior without loss of motor coordination in mice as the reference compounds did. The ED50 values of MKC-242, buspirone, tandospirone and diazepam were 1.7, 42, 80 and 2.0 mg/kg, p.o., respectively. The duration of the suppression of fighting by MKC-242 was longer than those of buspirone and tandospirone and comparable to that of diazepam. Similar results were also obtained with the water-lick conflict test in rats. The plasma concentration of MKC-242 in rats was much higher than the reported value of buspirone during 0.25-6 hr after oral administration. In addition, MKC-242 reduced marble burying behavior without reduction of motor activity. Fluoxetine, tandospirone and diazepam also reduced the behavior at non-sedative doses. These findings indicate that MKC-242 possesses a longer-lasting anxiolytic effect than azapirones. This might be due to the high concentration of the compound in plasma. In addition, it is also suggested that MKC-242 possesses an antiobsessional effect.

Free volume properties of model fluids and polymers: Shape and connectivity

The Cavity Energetic Sizing Algorithm (CESA) method of in’t Veld (J Phys Chem B 2000, 104, 12028) is extended to characterize the nonspherical nature of free volume. The new technique is introduced with reference to simple model fluids (water, hard spheres, and a Lennard-Jones fluid) and then applied to polymers of interest to membrane scientists. A set of shape parameters is introduced, characterizing nanopores in terms of surface area, volume, radius of gyration, and span. Results are presented for Lennard-Jones fluid and bard sphere fluid, and for the high free volume polymers (polytrimethyl-silyl-propane) poly(l-trimethylsilyl-l-propyne) (PTMSP) and a random copolymer of 2,2-bis(trifluoromethyl)-4,5-difluoro-1,3-dioxole (TFE/BDD). PTMSP is observed to have an average free volume cluster span of 1.43 nm, compared to TFE/BDD with an average cluster span of 0.98 nm, consistent with the markedly higher permeability of CO2 observed in PTMSP. An additional method for measuring free volume is introduced, similar to a method introduced by Greenfield and Theodorou (Macromolecules 1993, 26, 5461; Mol Simul 1997, 19, 329; Macromolecules 1998, 31, 7068; 2001, 34, 8541), which measures free volume relative to a specific probe. The method captures 1-3 times the fractional cavity volume captured by CESA. Free volume measurements are presented for a set of polysulfones with respect to noble gas probes (J Chem Phys 2005, 122, 84906; J Mol Struct 2005, 739, 173). (c) 2006 Wiley Periodicals, Inc.

Identification, Separation and Characterization of Process-Related Impurities of Bifendate Derivative (DB-6), an Investigational Agent Combating Acute Liver Failure

DB-6, with an IUPAC name of (Z)-5-(2,4-di-tert-butyl-6-((2,4-dioxothiazolidin-5-ylidene)methyl)phenyl)-5′-methyl-7,7′-dimethoxy-[4,4′-bibenzo[ d][1,3] dioxole]-5,5′-dicarboxylate,is an investigational agent for acute liver failure. The focus of this study is the identification and characterization of major unknown impurities in DB-6 bulk drug samples. Four major impurities of DB-6 were detected by a high-performance liquid chromatography (HPLC) method and designated as IMP-I, IMP-II, IMP-III and IMP-IV. Accurate masses of these impurities were determined by using a Q-TOF mass spectrometer. Based on chromatographic, spectrometric data and plausible chemical transformation mechanism, the structures of IMP-I, IMP-II, IMP-III and IMP-IV were identified, respectively, as bifendate, (E)-5-(2,4-ditert- butyl-6-((2,4-dioxothiazolidin-5-ylidene) methyl) phenyl)-5′-methyl-7,7′- dimethoxy-[4,4′-bibenzo[d][1,3] dioxole]-5,5′-dicarboxylate, (Z)-5( 3,5-di-tert-butyl-2-hydroxybenzylidene) thiazolidine-2,4-dione and bis(2,4-di-tert-butyl-6-((Z)-(2,4-dioxothiazolidin-5-ylidene) methyl)phenyl)- 7,7′-dimethoxy-[4,4′-bibenzo[d][1,3] dioxole]-5,5′-icarboxylate. The impurities were isolated by preparative-HPLC or preparative high-speed counter-current chromatography and their structures were confirmed by NMR spectroscopy.

Ryecyanatines A and B and ryecarbonitrilines A and B, substituted cyanatophenol, cyanatobenzo[1,3]dioxole, and benzo[1,3]dioxolecarbonitriles from rye (Secale cereale L.) root exudates: Novel metabolites with allelopathic activity on Orobanche seed germination and radicle growth

Orobanche and Phelipanche species (the broomrapes) are root parasitic plants, some of which represent serious weed problems causing heavy yield losses on important crops. Current control relies on the use of certain agronomic practices, resistant crop varieties, and herbicides, albeit success has been marginal. Agronomic practices such as the use of allelopathic species in intercropping or cover crops, or the use of direct seedling over residues of allelopathic species incorporate the principle of allelopathy exerted by molecules exuded from roots or released by crop residues to control broomrapes. In addition, the isolation of natural substances from root exudates of plants with potential to inhibit broomrape development opens the door to the design of new herbicides based on natural and benign sources. Ryecyanatines A and B and ryecarbonitrilines A and B, the first new substituted cyanatophenol, substituted cyanatobenzo[1,3]dioxole, and the latter two new substituted benzo[1,3]dioxolecarbonitriles were isolated from rye (Secale cereale L.) root exudates. They were characterized as 4-cyanato-2-methoxyphenol, 2-cyanato-benzo[1,3]dioxole, 2-methoxybenzo[1,3]dioxole-5-carbonitrile and benzo[1,3]dioxole-2-carbonitrile by spectroscopic (essentially NMR and HRESI MS spectra) methods. These compounds were investigated for allelopathic activity on Orobanche germination and development. Ryecarbonitriline A induced germination of Orobanche cumana seeds, and this germination can be considered as suicidal because O. cumana does not parasite rye roots and cannot survive without host resources beyond germination stage. In addition, ryecyanatine A promotes a rapid cessation of O. cumana, Orobanche crenata and Orobanche minor radicle growth with the promotion of a layer of papillae at the radicle tip in O. cumana and O. crenata hampering the contact of the parasite to the host. Ryecarbonitriline B also displayed the same activity although being less active than ryecyanatine A and mainly restricted to O. cumana. (C) 2014 Elsevier Ltd. All rights reserved.

Ultrafast chemistry of nanoenergetic materials studied by time-resolved infrared spectroscopy: Aluminum nanoparticles in teflon

Ultrafast mid-infrared (IR) spectroscopy is used to monitor chemical reactions initiated by flash-heating a nanoenergetic material consisting of 30 nm diameter Al nanoparticle fuel in a Teflon(AF) oxidizer. Teflon(AF) is a copolymer of tetrafluoroethylene (TFE) and 2,2-bis(trifluoromethyl)-4,5-difluoro-1,3-dioxole (dioxole), so Al can react with several different moieties. Transitions associated with CF2 stretching of TFE or CFO stretching or CF3 stretching of dioxole were monitored. The reactions of Al with CFO occurred with time constant (k(1))(-1) = 50 (+/- 20 ps); reactions of Al with CF2 or CF3 were more than 10 times slower, (k(2))(-1) = 0.7 (+/- 0.05 ns). An interesting frequency oscillation is seen in the 1148 cm(-1) band, where the peak frequency undergoes a time-dependent shift from 1148 to 1155 cm(-1) and then back to 1148 cm(-1). Due to the coincidence of CFO and CF2 stretching transitions, this band in the copolymer represents an amalgamated vibration with amplitude on both TFE and dioxole. As concentration is varied from pure dioxole to pure TFE, the band blue-shifts. A kinetic scheme and a model for the concentration dependence of the amalgamated vibration frequency are developed, which show that the frequency oscillation is a consequence of the arrangement of reactants on the nanoscale, which creates two types of oxidizer. The type adjacent to the Al nanoparticle is in a region of high local fuel concentration, while the other type is too distant from the fuel to react.

Permeation and sorption of organic solvents and separation of their mixtures through an amorphous perfluoropolymer membrane in pervaporation

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.

Preparation of Hyflon AD60/PVDF composite hollow fiber membranes for vacuum membrane distillation

Hydrophobic membrane is desired to avoid pore wetting phenomenon in membrane distillation (MD). In the present paper, highly hydrophobic Hyflon AD60/PVDF composite hollow fiber membranes were prepared by coating a copolymer (Hyflon AD60) of tetrafluoroethylene (TFE) and 2,2,4-trifluoro-5-trifluoro methoxy-1,3-dioxole (TTD) on poly(vinylidene fluoride) (PVDF) membranes. The effects of Hyflon AD60 concentration, coating time, heat-treatment temperature and heat-treatment time on the structures and performances of Hyflon AD60/PVDF composite hollow fiber membranes in vacuum membrane distillation (VMD) process were investigated. The results show that the hydrophobicity of PVDF hollow fiber membrane was significantly improved by coating Hyflon AD60. The optimized Hyflon AD60 concentration, coating time, heat-treatment temperature and heat-treatment time were 0.1 wt%, 10-20 min, 40-50 degrees C and 9 h, respectively. Employing NaCl solution with concentration of 35 g x L-1, under a vacuum of 0.09 MPa and feed temperature of 70 degrees C, the water flux and salt rejection of the composite hollow fiber membrane in VMD process reached to approximately 10 kg x m(-2) x h(-1) and higher than 99.9 %, respectively, and kept stable, indicating that Hyflon AD60/PVDF composite membrane is an excellent candidate for operation in VMD operation.

Weak C-H center dot center dot center dot X (X = O, N) hydrogen bonds in the crystal structure of dihydroberberine

Dihydroberberine (systematic name: 9,10-dimethoxy-6,8-dihydro-5H-1,3-dioxolo[4,5-g]isoquinolino[3,2-a]isoquinoline), C20H19NO4, a reduced form of pharmacologically important berberine, crystallizes from ethanol without interstitial solvent. The molecule shows a dihedral angle of 27.94 (5)degrees between the two arene rings at the ends of the molecule, owing to the partial saturation of the inner quinolizine ring system. Although lacking classical O-H or N-H donors, the packing in the crystalline state is clearly governed by C-H center dot center dot center dot N and C-H center dot center dot center dot O hydrogen bonds involving the two acetal-type C-H bonds of the 1,3-dioxole ring. Each dihydroberberine molecule is engaged in four hydrogen bonds with neighbouring molecules, twice as donor and twice as acceptor, thus forming a two-dimensional sheet network that lies parallel to the (100) plane.
