Thermal, photosynthesis and antibacterial studies of bioactive safrole derivative as precursor for natural flavor and fragrance

Safrole [5-allylbenzo[d][1,3]dioxole] was subjected to photochemical oxidation reaction with hydrogen peroxide in the presence of sodium lamp to give the corresponding epoxy derivative [5-oxiranylmethylbenzo[1,3]dioxole. The thermal oxidation of safrole with 3-chloroperoxybenzoic acid at room temperature gave the same epoxide derivative in quantitative yield. Antibacterial studies were carried out on safrole and its photoproducts ( safrole epoxide and safrole hydroperoxide). The results revealed that safrole hydroperoxide was the most effective than safrole epoxide than safrole against Gram-positive bacteria Bacillus subtilis ATCC6633, Staphylococcus aureus ATC C25923, and Gram negative bacteria Escherichia coli ATCC25422. This result proved that safrole derivatives are beneficial to human health, having the potential to be used for medical purposes. (C) 2011 Production and hosting by Elsevier B.

Prediction of the binding modes between BB-83698 and peptide deformylase from Bacillus stearothermophilus by docking and molecular dynamics simulation

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.

Rigid Rod-Based FRET Probes for Membrane Sensing Applications

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.

The influence of ochratoxin A on DNA adduct formation by the carcinogen aristolochic acid in rats

Exposure to the plant nephrotoxin and carcinogen aristolochic acid (AA) leads to the development of AA nephropathy, Balkan endemic nephropathy (BEN) and upper urothelial carcinoma (UUC) in humans. Beside AA, exposure to ochratoxin A (OTA) was linked to BEN. Although OTA was rejected as a factor for BEN/UUC, there is still no information whether the development of AA-induced BEN/UUC is influenced by OTA exposure. Therefore, we studied the influence of OTA on the genotoxicity of AA (AA-DNA adduct formation) in vivo. AA-DNA adducts were formed in liver and kidney of rats treated with AA or AA combined with OTA, but no OTA-related DNA adducts were detectable in rats treated with OTA alone or OTA combined with AA. Compared to rats treated with AA alone, AA-DNA adduct levels were 5.4- and 1.6-fold higher in liver and kidney, respectively, of rats treated with AA combined with OTA. Although AA and OTA induced NAD(P)H:quinone oxidoreductase (NQO1) activating AA to DNA adducts, their combined treatment did not lead to either higher NQO1 enzyme activity or higher AA-DNA adduct levels in ex vivo incubations. Oxidation of AA I (8-methoxy-6-nitrophenanthro[3,4-d]-1,3-dioxole-5-carboxylic acid) to its detoxification metabolite, 8-hydroxyaristolochic acid, was lower in microsomes from rats treated with AA and OTA, and this was paralleled by lower activities of cytochromes P450 1A1/2 and/or 2C11 in these microsomes. Our results indicate that a decrease in AA detoxification after combined exposure to AA and OTA leads to an increase in AA-DNA adduct formation in liver and kidney of rats.

Eco-sustainable synthesis and biological evaluation of 2-phenyl 1,3-benzodioxole derivatives as anticancer, DNA binding and antibacterial agents

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.

Perfluoropolymer membrane behaves like a zeolite membrane in dehydration of aprotic solvents

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.
