An enantioselective and regioselective total synthesis approach to chiral 1,4-benzodioxane lignans (2R,3R)- and (2S,3S)-3-(4-hydroxy-3-methoxyphenyl)-2-hydroxymethyl-1,4-benzodioxan-6-carbaldehyde is reported.
Treatment of the diiron hexacarbonyl complexes [μ-SCH2CH(R)S-μ]Fe2(CO)6 (R = CH2OH, 1; CH3, 2; CH2CH3, 3) with a monophosphine ligand tris(2-methoxyphenyl)phosphine in the presence of Me3NO 2H2O gave monosubstituted complexes [μ-SCH2CH(R)S-μ]Fe2(CO)5[P(C6H4OCH3-2)3] (R = CH2OH, 4; CH3, 5; CH...
A new method based on matrix solid-phase dispersion (MSPD) coupled with liquid chromatography tandem mass spectrometry has been developed for the determination of imidacloprid in rice. The molecularly imprinted polymers were synthesized and applied as the dispersant of MSPD for selective extract...
In this work, we report on a dual-behavior electrochemical/optical sensor for sensitive determination of Imidacloprid by fluorescent dye (fluorescein, FL) and imprinted polymer modified europium doped superparamagnetic iron oxide nanoparticles ([email protected]@MIP). The imidacloprid (IMD)-impr...
Highly ordered mesoporous copper ferrite (meso-CuFe2O4) with high surface area and large pore size was successfully fabricated and firstly proposed as a heterogeneous Fenton catalyst. It was synthesized through the nanocasting strategy by using KIT-6 as hard template. The morphology and physicoc...
This study reported that a hapten of imidacloprid, 1-[(6-Carboxylethylthio-3- pyridinyl)methyl)-N-nitro-imidazolidinimine was synthesized using technical material of imidacloprid to react with 3-mercaptopropionic acid in hot alkaline solution. The hapten was conjugated to bovine serum albumin (B...
The study focuses on the degradation of imidacloprid (IMI) through persulfate (PS) oxidation. The performance of different iron activators like magnetic biochar (MBC), nanoscale ferrous-ferric oxide (nFe3O4) and nanoscale zero-valent iron (nZVI) for PS activation was investigated by their applic...
This paper presents a new method for the determination of imidacloprid in water samples; one of the most widely used neonicotinoid pesticides in the farming industry. The method is based on the measurement of excitation–emission spectra of photo-induced fluorescence (PIF-EEMs) associated with s...
Dissipation of β-cyfluthrin and imidacloprid in chickpea pods and leaves was measured following three applications of Solomon 300 OD (β-cyfluthrin 9 percent +imidacloprid 21 percent) at 200 and 400 mL ha−1. Residues of β-cyfluthrin on chickpea pods and leaves were found to be below its limit ...
This paper presents a method for the determination of imidacloprid in honeybees based on the measurement of excitation-emission spectra of photo-induced fluorescence (PIF-EEMs) associated to unfolded partial least squares coupled to residual bilinearization (U-PLS/RBL) algorithm. As a preliminar...
Imidacloprid (IC) pesticide is used as a poison for a specific group of living organisms. On the other hand, modern insecticides in the aquatic environment will have serious problems for humans and other living organisms. Photocatalytic degradation can be a promising way to improve water. In the...
Rationale and ObjectivesThis study aimed to determine the potential degree of radiation dose reduction achievable using Advanced Modeled Iterative Reconstruction (ADMIRE) in abdominal computed tomography (CT) while maintaining image quality. Moreover, this study compared differences in image noi...
BackgroundA 5-HT3 receptor antagonist, tropisetron, has been reported to exhibit an anti-inflammatory effect in chronic inflammatory diseases by antagonizing a particular subtype of serotonin receptors. We investigated whether overproduction of cytokines could be controlled by intervention with ...
Nicotine has ameliorating effects on sensorimotor gating deficits in schizophrenia. We have shown that nicotine ameliorated disruption of prepulse inhibition (PPI) via the α7 nicotinic acetylcholine receptor (nAChR) in Wistar rats. The 5-HT3 receptor antagonist tropisetron was recently found to...
A simple and sensitive high performance liquid chromatography method with UV detection was described for the determination of tropisetron in human plasma. The prepared sample solution was injected onto BDS-C8 reversed column using a mixture of ammonium acetate (100 mM, PH adjusted to 4.3 with gl...
An assay method to quantify ondansetron (OND), granisetron (GRA) and tropisetron (TRO) in goat plasma has been successfully developed and validated. This method procedure for the analysis of OND, GRA and TRO was involved of extracting samples with hydrophilic interaction liquid chromatography (H...
Although cocaine readily induces taste aversions, little is known about the mechanisms underlying this effect. Recent work has shown that cocaine's actions on serotonin (5-HT) may be involved. To address this possibility, the present experiments examined a role of the specific 5-HT receptor...
The objective of this study was to determine the neuroprotective role of tropisetron on retinal ganglion cells (RGCs) as well as to explore the possible mechanisms associated with alpha7 nAChR-induced neuroprotection. Adult pig RGCs were isolated from all other retinal tissue using a two-step pa...
ObjectiveThe objective of the present investigation was to explore the possible effect of the 5-HT3 receptor antagonist tropisetron on the expression levels of the inflammatory factors interleukin 6 (IL-6), creatine kinase isoenzyme (CK-MB), soluble growth stimulating gene 2 protein (sST2) and i...
