High temperature resins containing phenylethynyl groups that are processable by transfer molding have been prepared. These phenylethynyl containing oligomers were prepared from aromatic diamines containing phenylethynyl groups and various ratios of phthalic anhydride and 4-phenylethynlphthalic anhydride in glacial acetic acid to form a mixture of imide compounds in one step. This synthetic approach is advantageous since the products are a mixture of compounds and consequently exhibit a relatively low melting temperature. In addition, these materials exhibit low melt viscosities which are stable for several hours at 210-275 C., and since the thermal reaction of the phenylethynyl group does not occur to any appreciable extent at temperatures below 300 C., these materials have a broad processing window. Upon thermal cure at ?300-350 C., the phenylethynyl groups react to provide a crosslinked resin system. These new materials exhibit excellent properties and are potentially useful as adhesives, coatings, films, moldings and composite matrices.

Six samples, including wood and jet-like material from the same mummified wood specimens, together with two ‘true’ jet samples, were studied using pyrolysis gas chromatography-mass spectrometry (Py-GC/MS) to obtain detailed insight into the process leading to the formation of jet. Based on morphological and chemical data obtained, the process of “jetification” is characterised by a rapid change when mummified wood is re-exposed to sunlight and aerobic conditions. The transformation from mummified wood to jet is probably caused by relatively small chemical changes, leading to extra linkages between the phenolic compounds and causing the structure to become much more rigid, which is reflected in increased inertness of the material at the macroscopic level.

Poppy (Papaver somniferum) is a traditional source of isoquinoline alkaloids, especially morphine, codeine and papaverine that exhibit a wide spectrum of therapeutic effects. Due to beneficial properties, poppy has been used by humankind for several thousand years and is still being used around the world. The present study was aimed to investigate alkaloid composition and biological activity of various parts of the plant (leaves, stems, roots, capsules, flowers, seeds) in an ornamental variety of P. somniferum. The alkaloid content rangedwithin 0.16 ? 6.5 mg/g fresh weight of raw plant material. The major components of the alkaloid fraction were papaverine (37.7 ? 2062.9 mug/g), codeine (7.4 ? 1280.5 mug/g) and morphine (3.25 ? 929.3 mug/g). The P. somniferum alkaloid extract produced a strong antioxidant effect, which was evaluated using the radical-scavenging DPPH, ABTS and FRAP assays. The antioxidant properties were characterized by IC50 values ranging within 35.1 ? 157.6 mug/mL for DPPH radical and 138.5 ? 306.3 mug/mL for ABTS??+ radical scavenging. The ferric reducing antioxidant power (FRAP) values varied from 59.75 to 1348.71 mM FeSO4/g extract. The alkaloid extract was active against all human tumor cell lines studied (HeLa, Caco-2, MCF-7, CCRF-CEM and CEM/ADR 5000). The methanol extract exhibited a pronounced cytotoxicity against most of cancer cell lines studied, especially those with a low expression of ABC transporters.

The soil memory recorded in paleosols of loess-paleosol sequences is an important contributor to our understanding of past climatic conditions. Molecular proxies based on the organic matter preserved in paleosols form an essential part of this record, but the long-term preservation of SOM is poorly understood, especially for sediment traps and slope profiles. This paper addresses the composition of organic material from the Early Weichselian A-horizons of the Rocourt paleosol, a major paleostratigraphic marker for the Eemian and Early Weichselian in Western Europe. NaOH-extractable organic matter from an exceptionally thick Rocourt profile in the Kesselt Quarry (Belgian Loess Belt) was analyzed by pyrolysis-Gas Chromatography/Mass Spectrometry (pyrolysis-GC/MS) and the results evaluated against paleopedological data. The molecular composition of the organic matter at Kesselt was compared with reference samples from two nearby quarries (including the type locality at Veldwezelt-Hezerwater), and to a sample from the contemporary Nussloch sequence in Germany. The SOM composition found at the four sites indicated a large content of microbial matter and was dominated by carbohydrates and N compounds, many of which were not reported before from SOM pyrolysates. Differences in the molecular composition between samples, both within profiles and between sites, coincided with differences in landscape position (slope-shoulder-plateau) and fossil redox conditions (surface gleys). Samples form drier and more upland situations contained more burnt material, while samples from slope profiles and surface gleys contained even more microbial material, in particular chitin. Results therefore suggest that the admixture of microbial SOM is considerable in loess-paleosols and that differences in edaphic conditions (in particular slope position and soil moisture) and occurrence of wildfires are important for the long-term preservation of SOM. These should therefore be considered when interpreting biogeochemical proxies.

Donor-acceptor type (DA-type) polymeric photovoltaic material with a dicarboxylic imide-substituted benzene (phthalimide) derivative as electron-withdrawing units, poly[4,4?-didodecyl-2,2?-bithiophene-co- 5,5?-(3,6-bis(thieno-2-yl)-N-octyl-phthalimide] (PDBTTPT), was synthesized by a Stille coupling reaction. It had an optical band gap of 1.96 V and a relatively low HOMO energy level of -5.34 eV in spite of it being a thiophene-based polymer. Photovoltaic devices with PDBTTPT/PC71BM active layers were fabricated under a variety of conditions for optimizing device performance. PDBTTPT exhibited the best power conversion efficiency (PCE) of 1.5% in the device where 80 wt.% of the PC71BM was contained in the active layer (PDBTTPT:PC71BM = 1:4, w/w) and which was pre-annealed at 120C for 10 min. In addition, a device which was pre-annealed at 140C for 10 min and a device which was post-annealed at 120C for 10 min showed analogous PCE values of 1.5% as well, although small differences were exhibited between various parameters, such as VOC, JSC, and FF.

The prodrug approach to resolving formulation, delivery, and toxicity limitations on problematic drugs has had its proponents and detractors. Over the last 10 years or so, about 20% of all new small molecule NCEs have been prodrugs-a number that will surprise some. As chemists begin to explore new chemical spaces, larger and more complex molecules present greater drug delivery challenges. Prodrugs provide a means of solving these challenges, but also have their limitations. Prodrugs are becoming an integral part of the drug discovery paradigm in some large pharma companies, and a number of small biotech companies have been built around the design and application of prodrugs to improve drug candidates. Some issues facing the area of prodrug research and the commercialization of prodrugs are discussed.

Electric Literature of 54008-77-4, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.54008-77-4, Name is 2-Bromobenzofuran, molecular formula is C8H5BrO. In a article，once mentioned of 54008-77-4

The combination of a vinyl-substituted aromatic or heteroaromatic and an alkyl bromide or iodide leads, in the presence of Zn and a catalytic amount of an Fe(II) salt, to a net reductive coupling. The new C-C bond is regiospecifically formed at rt at the beta-site of the alkene. The coupling only occurs in an aqueous micellar medium, where a radical process is likely, supported by several control experiments. A mechanism based on these data is proposed.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 54008-77-4

The substrate kinetics of a hyperthermostable alkaline lipase from Bacillus sonorensis 4R (BSL) was studied and the enzyme was used to develop presoak formulation for removing oil stains at 37 C and 80 C. The purified BSL was thiol activated with 112.49% and 37.49% enhancement in presence of 5 mM thiourea and dithiothreitol (DTT) respectively. BSL displayed higher specificity for mustard oil and cotton seed oil cake than olive oil as a standard substrate. The maximal velocity (Vmax) and Michaelis constant (Km) values determined in presence of olive oil, mustard oil and cotton seed oil cake were 5.0, 7.14, 5.55 muM and 3.22, 2.5 and 2.22 muM/ml/min respectively. Effect of phenylmethylsulfonyl flouride (PMSF) and N-Bromosuccinimide (NBS) on BSL catalyzed hydrolysis of olive oil, mustard oil and cotton seed oil cake were studied in terms of changes in Vmax, Km, catalytic efficiency and substrate utilization capacity. BSL catalyzed improved hydrolysis of cotton seed oil cake in presence of thiourea and retained 100% stability in presence of non-polar solvents, surfactants and detergents. BSL (15 Eu/100 ml) was effective in removal of olive oil stains studied at three aging periods (0, 7 and 15 d) and two washing temperatures (37 C and 80 C). The BSL action during wash performance studies for all aging periods was demonstrated clearly by quantitated fatty acid release. BSL exhibited excellent olive oil removal capacity than buffer (pH 9.0) and Tide (1%). The combination of BSL and Tide proved best formulation for stain removal of olive oil soiled fabrics.
