Many previous works have demonstrated that acetylcholinesterase (AChE) was enantioselectively inhibited by chiral organophosphorus insecticides (OPs) and a significant difference in reactivation existed for AChE inactivated (1R)- versus (1S,3S)-stereoisomers of isomalathion. It had been known α-naphthyl acetate esterase (ANAE), an enzyme which might play essential role the growth plants defense against environmental stress regulating concentration hormones plants, can be OPs. However, it...
To investigate the solubility of carbon dioxide (CO2) in geological fluids at different temperatures and pressures, we developed a method for measuring using an optically transparent fused silica capillary cell as high-pressure optical combined with Raman spectroscopy under sequestration conditions (temperatures up to 353.15 K pressure 30.0 MPa). On basis fact that band intensity active species is proportional its concentration, determined linear correlation between known CO2 concentration...
Silica-modified titania (SMT) powders with different atomic ratios of silica to titanium (Rx) were successfully synthesized by a simple ultrasonic irradiation technique. The prepared samples characterized X-ray diffraction (XRD), FT-IR spectroscopy, transmission electron microscopy (TEM), photoelectron spectroscopy (XPS), and ultraviolet visible spectroscopy. specific surface area was measured according BET theory. Results indicate that the addition can suppress crystalline size growth...
Six chiral pesticides containing sulfur/phosphorus atoms were separated by supercritical fluid chromatography with CO2 as the main mobile phase component. The effect of stationary phase, different type and concentration modifiers, column temperature, backpressure on separation efficiency was investigated to obtain appropriate condition. Five (isofenphos-methyl, isocarbophos, flufiprole, fipronil, ethiprole) baseline under experimental conditions, while isofenphos only obtained partial...
The enantioselective metabolism of flufiprole in rat and human liver microsomes vitro was investigated this study. separation determination were performed using a liquid chromatography system equipped with triple-quadrupole mass spectrometer Lux Cellulose-2 chiral column. rac-flufiprole dramatically different the presence β-nicotinamide adenine dinucleotide phosphate regenerating system. half-lives (t1/2) 7.22 21.00 min, respectively, for R-(+)-flufiprole, whereas values 11.75 17.75...
Abstract A series of organophosphorous compounds (OPs), 1‐(substituted phenoxyacetoxy)alkylphosphonates containing a chiral carbon atom, show notable herbicidal activities. In this study, the enantioselective separation and biological toxicity all these were investigated. The on columns Chiralpak AD, AS, Chiralcel OD, OJ compared under various chromatographic conditions. All analytes investigated obtained baseline resolution ( R s > 1.5) AD column, which showed best capacity. Further...
Mandelic acid and its derivatives are important chiral analogs which widely used in the pharmaceutical synthetic industry. The present study investigated enantiomeric separation of six mandelic acids (mandelic acid, 2-chloromandelic 3-chloromandelic 4-chloromandelic 4-bromomandelic 4-methoxymandelic acid) on Chiralpak AD-3 column by supercritical fluid chromatography. influences volume fraction trifluoroacetic type percentage modifier, temperature, backpressure efficiency were investigated....
To investigate the volume expansion of a carbon dioxide (CO2) + n-hexane mixture at different temperatures and pressures, we developed measurement setup using an optically transparent fused silica capillary cell (FSCC) combined with Raman spectra. The results showed that method is feasible, water seal effective in its ability to avoid vaporization n-hexane, spectra can help ensure system equilibrium. factor CO2 increased increasing pressure from 1 10 MPa decreased temperature 30 80 °C. It...
Many chemical products used in the agrochemical industries contain chiral centers and consist of one or two pairs enantiomers, which can have important consequences regarding bioactivity.
