Molecular characterization of soil organic matter from native vegetation-pasture-sugarcane transitions in Brazil

Replacing pastures (PA) with sugarcane (SG) has been deemed an agronomically feasible strategy for sugarcane expansion in Brazil. However, there are some uncertainties about the environmental impacts regarding this land use change (LUC), mainly related to soil organic matter (SOM), a key factor of environmental sustainability of Brazilian ethanol. LUC-related losses of SOM can overcome the C savings from biofuels. The molecular composition of SOM was evaluated to understand the C dynamics regarding LUC from PA to SG, using native vegetation (NV) as reference. Our study area was located in the south-central region of Brazil. Soil sampling was performed at three depths (0-0.1 m, 0.2-0.3 m and 0.9-1 m) in three representative sites with known LUC history and management practice since 1970. Pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) was chosen to study SOM chemistry. Content and isotopic composition of soil organic C and N were also determined. The LUC caused decreases on C and N contents and on delta13C isotopic values. Depth was the major factor that influenced SOM composition, while the influence of LUC was mainly evident in surface soils and diminished rapidly with depth. The main difference in SOM composition undergoing the conversion PA-SG was a higher contribution from compounds associated to fresh litter inputs. The high contribution from fresh litter, having a relatively low mean residence time and increasing decomposition rates, is probably a major factor that drives C losses in areas undergoing sugarcane expansion.

Dual crosslinked phenylethynyl end-capped sulfonated polyimides via the ethynyl and sulfonate groups promoted by PEG

Typically, phenylethynyl (PE) end-capped oligomides require a temperature of 370 C for 1 h to develop a crosslinked system. A published method using poly(ethylene glycol)s (DM-PEG-250 and PEG-400) as cosolvents with NMP was effective in crosslinking the ethynyl end-caps at 250 C/3 h in nonsulfonated oligomides. The application of this novel crosslinked method to PE end-capped sulfonated oligomides was effective but caused a secondary crosslinked network via the sulfonic acid groups and ethylene glycol solvents. The solid-state 13C NMR spectral data on 13C-labeled end-caps in the PE-3F-SPI-3 oligomide provide evidence for the ethynyl to ethynyl and ethylene oxide sulfonate ester dual crosslinked structure. Infrared spectroscopy of model compounds also provides evidence for the presence of crosslinked sulfonate ester and appended sulfonate ester side chains. 13C NMR also provided quantitative data on the extent of the ethynyl to ethynyl crosslinking reaction and sulfonate ester crosslinks and side chains.

Biocatalytic Strategy for Highly Diastereo- and Enantioselective Synthesis of 2,3-Dihydrobenzofuran-Based Tricyclic Scaffolds

2,3-Dihydrobenzofurans are key pharmacophores in many natural and synthetic bioactive molecules. A biocatalytic strategy is reported here for the highly diastereo- and enantioselective construction of stereochemically rich 2,3-dihydrobenzofurans in high enantiopurity (>99.9% de and ee), high yields, and on a preparative scale via benzofuran cyclopropanation with engineered myoglobins. Computational and structure-reactivity studies provide insights into the mechanism of this reaction, enabling the elaboration of a stereochemical model that can rationalize the high stereoselectivity of the biocatalyst. This information was leveraged to implement a highly stereoselective route to a drug molecule and a tricyclic scaffold featuring five stereogenic centers via a single-enzyme transformation. This work expands the biocatalytic toolbox for asymmetric C?C bond transformations and should prove useful for further development of metalloprotein catalysts for abiotic carbene transfer reactions.

Design, synthesis and anticancer activity evaluation of novel C14 heterocycle substituted epi-triptolide

Two series of novel C14 heterocycle substituted epi-triptolide derivatives as potential anticancer agents were synthesized and tested for their cytotoxicity against SKOV-3 and PC-3 tumor cell lines. The introduction of C14beta-aryl heterocycle aminomethyl substituent to the leading compound was found to be an effective modification method to retain the potent anticancer activity. Meanwhile, the series of epi-triptolide derivatives (21-40) with C14alpha-hydroxyl group, still retained the natural product’s cytotoxicity. This is apparently challenges the classical structure-activity relationship of triptolide that considers the C14beta-hydroxyl group to be essential for its anticancer activity.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 83528-03-4 is helpful to your research. Application of 83528-03-4
