Due to its non-toxicity and environmentally friendly nature, carbohydrate based fatty acid (CFA) esters are encouragingly used as antimicrobials and synthetic intermediates. They also are notably applied in food, surfactant, and pharmaceutical industries. In this respect, Me 2,6-di-O-isopentanoyl-α-D-glucopyranoside (2), synthesized in a single step from Me α-D-glucopyranoside (1), was converted into four other 3,4-di-O-acyl esters (3 – 6). All the newly synthesized CFA esters (2 – 6) were applied for the first time to study decay resistances of aspen (Populus tremula) and pine (Pinus sibirica) wood from decay caused by white-rot (Polyporous versicolor L.ex. Fr.) and brown-rot (Postia placenta (Fr). Cke.) fungi. Most of these CFA esters protected these woods from fungal attack, reduced deterioration, and preserved the weight percentage of woods at a certain point. It is noted that the CFA esters compounds reduced the deterioration and suppressed the weight percentage loss of wood at a certain point and from low to moderate decay resistances against the selected fungi.

Jolivalt, C.; Neuville, L.; Boyer, F. D.; Kerhoas, L.; Mougin, C. published the artcile< Identification and Formation Pathway of Laccase-Mediated Oxidation Products Formed from Hydroxyphenylureas>, Safety of Methyl 4-chloro-2-hydroxybenzoate, the main research area is laccase oxidation hydroxyphenylurea polyaromatic compound quinone.

Hydroxyphenylureas are the first main metabolites formed in the environment from pesticide and biocide urea compounds Because fungi release potent exocellular oxidases, we studied the ability of laccases produced by the white rot fungus, T. versicolor, to catalyze in vitro the transformation of five hydroxyphenylureas, to identify transformation pathways and mechanisms. Our results establish that the pH of the reaction has a strong influence on both the kinetics of the reaction and the nature of the transformation products. Structural characterization by spectroscopic methods (NMR, mass spectrometry) of eleven transformation products shows that laccase oxidizes the substrates to quinones or to polyaromatic oligomers. Slightly acidic conditions favor the formation of quinones as final transformation products. In contrast, at pH 5-6, the quinones further react with the remaining substrate in solution to give hetero-oligomers via carbon-carbon or carbon-oxygen bond formation. A reaction pathway is proposed for each of the identified products. These results demonstrate that fungal laccases could assist the transformation of hydroxyphenylureas.

Wu, Chao; Irshad, Faisal; Luo, Maowei; Zhao, Yujun; Ma, Xinbin; Wang, Shengping published the artcile< Ruthenium Complexes Immobilized on an Azolium Based Metal Organic Framework for Highly Efficient Conversion of CO2 into Formic Acid>, Application of C24H36Cl4Ru2, the main research area is ruthenium complex metal organic framework catalyst carbon dioxide hydrogenation; formic acid carbon dioxide hydrogenation catalyst.

A series of efficient heterogenized ruthenium catalysts designated as Rux-NHC-MOF (x=1, 2, 3; NHC=N-heterocyclic carbene; MOF=metal organic framework) were successfully synthesized by the immobilization of different ruthenium complexes RuCl3, [RuCp*Cl2]2 (Cp*=pentamethylcyclopentadienyl) and [Ru(C6Me6)Cl2]2 (C6Me6=hexamethylbenzene) on an azolium based MOF through post-synthetic metalation. The heterogenized catalysts were subsequently accessed for the catalytic hydrogenation of CO2 to formic acid. The resulting Ru3-NHC-MOF catalyst exhibited the highest activity because of its stronger electron-donating ability of C6Me6 ligand of [Ru(C6Me6)Cl2]2 complex, which is favorable for CO2 hydrogenation reaction. A high turnover number (TON) value up to 3803 was obtained at 120° under a total pressure of 8 MPa (H2/CO2=1) for 2 h with K2CO3 additive in N,N-Dimethylformamide (DMF) solvent. Furthermore, the heterogenized Ru3-NHC-MOF catalyst was effectively recovered through filtration without significant loss of catalytic activity.

Lee, Mee-Young; Seo, Chang-Sebo; Kim, Ji-Young; Shin, Hyeun-Kyoo published the artcile< Genotoxicity evaluation of Oryeong-san water extract using in vitro and in vivo tests>, Name: 2-(Bis(2-chloroethyl)amino)-1,3,2-oxazaphosphinane 2-oxide hydrate, the main research area is Salmonella Escherichia Oryeong san water extract genotoxicity.

Background: Oryeong-san, a mixture of five herbal plants, is a well-known therapy for renal-associated diseases such as those manifesting edema, dysuria, and oliguria. Methods: In the present study, we investigate the potential genotoxic effects of a water extract of Oryeong-san (ORSE) in three mutagenicity assays (an in vitro bacterial reverse mutation assay (Ames test) with Salmonella typhimurium and Escherichia coli strains, an in vitro mammalian chromosomal aberration test using Chinese hamster lung cells, and an in vivo micronucleus test using ICR mice bone marrow). Results: ORSE showed no genotoxicity in the Ames test up to 5000 μg/plate; the in vitro chromosome aberration test showed no significant structural aberrations with and without the S9 mix up to 5000 μg/mL, or the in vivo micronucleus test up to 2000 mg/kg body weight Conclusions: In conclusion, under the current test conditions, ORSE seems safe for use; however, other genotoxicity tests (e.g. sister-chromatid exchange or Comet) or chronic toxicity tests are warranted.

Deng, Xiangping; Liu, Renbo; Li, Junjian; Li, Zhongli; Liu, Juan; Xiong, Runde; Lei, Xiaoyong; Zheng, Xing; Xie, Zhizhong; Tang, Guotao published the artcile< Design, synthesis, and preliminary biological evaluation of 3',4',5'-trimethoxy flavonoid salicylate derivatives as potential anti-tumor agents>, Quality Control of 22717-55-1, the main research area is trimethoxy flavonoid salicylate derivative antitumor tubulin mol docking.

According to the pharmacophore combination principle, a set of new 3′,4′,5′-trimethoxy flavonoid salicylate derivatives were designed, synthesized, and evaluated for biol. activity. The cytotoxicity evaluation revealed that compound 10v exhibited higher potency than 5-Fu against HCT-116 cells. Preliminary biol. activity studies showed that compound 10v could inhibit the colony formation and migration of HCT-116 cells. Besides, the Hoechst 33258 staining assay and flow cytometry revealed that treatment with compound 10v induced the apoptosis of HCT-116 cells in a concentration-dependent manner, while it had no effect on their cell cycle. The WB anal. suggested that HIF-1α, tubulin, HK-2, and PFK might be the potential pharmacophore targets of compound 10v. Tubulin was a potential drug target for compound 10v, which was explained by analyzing the crystal structure of compound 10v complexed with tubulin. These results indicated that compound 10v might be a promising anti-tumor agent candidate, deserving further optimization and evaluation.

Wei, Haibing; Pei, Xueliang; Fang, Xingzhong published the artcile< Comparative study on polyimides from isomeric 3,3'-, 3,4'-, and 4,4'-linked bis(thioether anhydride)s>, HPLC of Formula: 118-45-6, the main research area is polyimide isomeric thioether anhydride preparation thermal mech property.

Three isomeric bis(thioether anhydride) monomers, 4,4′-bis(2,3-dicarboxyphenylthio) di-Ph ketone dianhydride (3,3′-PTPKDA), 4,4′-bis(3,4-dicarboxyphenylthio) di-Ph ketone dianhydride (4,4′-PTPKDA), and 4-(2,3-dicarboxyphenylthio)-4′-(3,4-dicarboxyphenylthio) di-Ph ketone dianhydride (3,4′-PTPKDA), were prepared through multistep reactions. Their structures were determined via Fourier transform IR, NMR, and elemental anal. Three series of polyimides (PIs) were prepared from the obtained isomeric dianhydrides and aromatic diamines in N-methyl-2-pyrrolidone (NMP) via the conventional two-step method. The PIs showed excellent solubility in common organic solvents such as chloroform, N,N-dimethylacetamide, and NMP. Their glass transition temperatures decreased according to the order of PIs on the basis of 3,3′-PTPKDA, 3,4′-PTPKDA, and 4,4′-PTPKDA. The 5% weight loss temperatures (T5%) of all PIs in nitrogen were observed at 504-519 °C. The rheol. properties of isomeric PI resins based on 3,3′-PTPKDA/4,4′-oxydianiline/phthalic anhydride showed lower complex viscosity and better melt stability compared with the corresponding isomers from 4,4′- and 3,4′-PTPKDA. In addition, the PI films based on three isomeric dianhydrides and on 2,2′-bis(trifluoromethyl)benzidine had a low moisture absorption of 0.27-0.35%. © 2011 Wiley Periodicals, Inc.
