The synthesized compounds were obtained by a subsequent N-alkylation and 1,3-dipolar cycloaddition reactions, their structures were identified by spectroscopy techniques (1H NMR, 13C NMR and 2D HSQC), and confirmed by mass spectrometry (HRMS). The spectroscopic data also show that the 1,3-...
High-performance liquid chromatography coupled with mass spectrometry (HPLC-MS) was used to analyze the main degradation products and pathways. This study demonstrates that bimetallic organic framework carbon-derived materials with synergistic effects have great application prospects as non-homogeneous Fenton...
Therefore, PORCN inhibitors block the secretion of WNT ligands through inhibition of posttranslational acylation of WNT ligands. However, similar to other cancer therapies targeting the Wnt pathway, skeletal side effects such as impairment of bone mass and strength and increase in bone resorption were...
However, the exact role of the inhibitors in influencing the corrosion inhibition (CI) process of active metals in saline solutions is not fully understood. The common hypothesis is that the organic inhibitors adsorb on the surface forming a protective film7,8,9,10,11. In this process, the o...
Chemical signature of airborne particulates and deposition dusts is subject of study since decades. Usually, three complementary composition markers are in
. Shinya et al. (2016) isolated the oral secretions fromMythimna loreyi, a chewing insect, and identified FAC. Although FAC alone had negligible elicitor activity in rice, it promoted the activity of the high molecular mass fraction, resulting in the accumulation of reactive oxygen species and ...
triple-quadrupole mass spectrometer operatingin a chemical ionization (CI) mode with methaneas carrier gas.Molecular weights and polydispersityindices of the polymers were estimated inTHF by a Waters Associate gel permeation chromatography(GPC) system.A set of monodisperse...
Methyl salicylate (Sigma-Aldrich) was used as the internal standard. The supernatant was removed to detect the SA content using a liquid chromatography-mass spectrometry (LC–MS) system (QTRAP5500, SCIEX). The samples were analysed using high-performance liquid chromatography (HPLC). 4.6 Y1H ...
Our results demonstrate the self-aggregation of NNH in polar solvents and identify the most likely dimer configuration, which is antiparallel π-stacked and stabilized by hydrogen bonds between hydroxyl and nitro groups. Given its broad applications in mass spectrometry, environmental remediation, and ...
The proposed approach, based on kinetic theory, considers the local perturbation of kinetic energy through mass fluctuation, weighted by a function dependent on the thermal conductivity of the uncorrelated system and the local structure. The local structure is described in terms of the concentration ...
