Lavender oil, obtained from the flowers of Lavandula angustifolia (Family: Lamiaceae) by steam distillation, The major component of lavender oil is linalyl acetate was isolated and subjected to oxidation thermally and photochemically using (mcpba and H2O2) respectively to produce mixture of 6,7-...

Olmesartan-associated enteropathy (OAE) is a life-threatening pathological condition, but its underlying mechanisms have not been elucidated. Although intestinal hypermotility is frequently accompanied by chronic diarrhea, there have been no studies of olmesartan-induced hypermotility. Intestina...

Preventing vascular damage is considered an effective strategy in patients who suffer from chronic obstructive pulmonary disease (COPD) with hypertension. Here, we investigated vascular damage in COPD-like and hypertensive rats, which demonstrated the presence of the three related factors of COP...

Speed of kill and percentage kill of nitenpyram (CAPSTAR®) was compared to fipronil (Frontline® spot-on), imidacloprid (Bayvantage®/Advantage™), selamectin (Stronghold™/Revolution™) and cythioate (Cyflee®) against adult fleas on cats and dogs 3 and 8 h post-treatment. Selamectin was used on dogs...

A thin-layer chromatography method is reported for the separation of dicrotophos, ethion (or phorate), fensulfothion, oxydemeton-methyl, phosmet, phospholan, and trichlorfon. The procedure involves the use of commercially prepared silica gel 1B Baker-flex plates and developing with 2,2,4-trimeth...

Fensulfothion, O,O-diethyl O-[p-(methylsulfinyl)phenyl] phosphorothioate, an organophosphorus pesticide, inhibits the activity but not the de novo synthesis of acetylcholinesterase in pea (Pisum sativum) roots. The rate of incorporation of labeled amino acids from 14C-labeled chlorella protein h...

Carbofuran added to soil samples from fields previously treated with this insecticide for soil insect control broke down much faster than in soil from fields with no history of carbofuran use. In experimental field plots, a second annual application of carbofuran or fensulfothion broke down much...

The 96-h LC50 values of methyl parathion and fensulfothion (with the 95% confidence limits in parentheses), to the freshwater fish Mystus cavasius were, respectively, 5·9 (5·4 to 6·5) and 16·5 (14·8 to 17·8) ppm. Both the pesticides induced severe morpho-anatomical deformities and behaviou...

Publisher SummaryThis chapter provides the basic synthesis paths routes for the manufacture of fensulfothion, with a listing of the main raw materials and intermediates used in the synthesis of fensulfothion. Fensulfothion is commercially known as Dasanit or Terracur, and it belongs to the phosp...

Oxidative degradation of fensulfothion, a model organophosphorus compound, has been investigated by pulse radiolysis and H2O2/UV photolysis. A nearly complete transformation of fensulfothion was observed within 4 min of irradiation. Very little Total Organic Carbon (TOC) reduction was obtained a...

Two series of 1,3-diphenyl-1H-pyrazole derivatives containing rhodanine-3-alkanoic acid groups were identified as competitive protein tyrosine phosphatase 1B (PTP1B) inhibitors. Among the compounds studied, IIIv was found to have the best in vitro inhibition activity against PTP1B (IC50 = 0.67 ±...

The activity coefficients and excess thermodynamic functions at infinite dilution were evaluated from gas chromatographic measurements for a number of binary diphenyl methyl phosphate-diluent systems. The interactions between the phenyl groups of DPMP and a diluent are predominant whereas the ce...

To improve the safety of lithium-ion batteries, cresyl diphenyl phosphate (CDP) was used as a flame retardant additive in a LiPF6 electrolyte solution. The flammability of the electrolytes containing CDP and the electrochemical performances of the cells, LiCoO2/Li, graphite/Li and the battery Li...

Meagre and suboptimal therapeutic response along with the side effect profile associated with the existing anticancer therapy have necessitated the development of new therapeutic modalities to curb this disease. Bearing in mind the current scenario, a series of 1,2,3-triazole linked 3-(1,3-diphe...

A novel method for the stereospecific synthesis of 1,5-disubstituted tetrazoles from ketoximes via the Beckmann rearrangement was developed using diphenyl phosphorazidate (DPPA) as both the oxime activator and azide source. Various ketoximes were transformed into the corresponding 1,5-disubstitu...

This work describes a new analytical method useful for monitoring the human exposure to the endocrine-disrupting plasticizer triphenyl phosphate (TPP) via nail polish use. The method allows trace determination of this parent compound and its main metabolite, namely diphenyl phosphate (DPP), in u...

Download high-res image (34KB)Download full-size imageSelective removal of one phenyl group from alkyl diphenyl phosphates is reported. Catalytic hydrogenation on palladium catalyst (Pd/C) under atmospheric pressure provides the corresponding monophenyl phosphates in 70–89% yield. The method is...

Six 5.0 mol% crosslinked poly[(styrylmethyl)hexadecyldimethylammonium chloride] latexes containing 8–67% quaternization were synthesized via two-stage process and used as supports for o-iodosobenzoate (IBA) catalyst in the hydrolysis of model organophosphate compound p-nitrophenyl diphenyl phos...

In this article, some novel extractants were synthesized for the separation of Th and rare earth (RE). Among the synthesized neutral organophosphorus extractants, n-octyl phosphate diphenyl (ODP) revealed excellent extraction efficiencies and selectivities for Th(IV). Moreover, loading capacity ...

Development of many branches of industry has stimulated the search for new, effective surfactants with interesting properties. Potential use of alkyl glucose derivatives on a large scale, raises questions about the possible risks associated with their entry into the natural environment. To be ab...
