Cyclomaltoheptaose (cycloheptaamylose) has been crystallized with 1-adamantanemethanol as the guest molecule. The complex crystallized in space group C2221, with unit-cell dimensions a = 19.162 (13), b = 23.965 (17), and c = 32.597 (27) Å. The structure was solved by rotation—translation search...

A novel approach to prepare 4-anilinoquinazoline derivatives based on the transformation of indoline-2,3-dione to formamidine was developed. The processes with this approach are simple, efficient, and environmentally friendly. The efficiency of this approach was evaluated by synthesizing 17 4-an...

Herein, a series of new ruthenium(II) complexes with the general molecular formula [RuCl2(arene)(NHC)], (arene = η6-p-cymene, NHC = N-heterocyclic carbene) were synthesized from in situ prepared silver(I)-NHCs by the transmetallation method. These complexes were fully characterized by analytica...

A new radical initiator, 2,5-dimethyl-2,5-di(2-ethylhexanoylperoxy)hexane (DMDEHPH), has been used to initiate styrene (ST) and methyl methacrylate (MMA) polymerization in the temperature range of 50–80 °C and DMDEHPH concentration range of 0.005–0.100 mol/L. The effects of initiator concentr...

The aim of this study was to investigate the genotoxic effects of potassium bromate, which is used as a bleaching agent in flour, on human peripheral blood lymphocytes in vitro by sister chromatid exchange (SCE), chromosomal aberrations (CA) and micronucleus (MN) tests, and also to determine whe...

The ataxia telangiectasia mutated (ATM) protein is a pivotal multifunctional protein kinase predominantly involved in DNA damage response, as well as in maintaining overall functional integrity of the cells. Apart from playing its major role in regulating the cellular response to DNA damage, ATM...

The synthesis of copper nanostructures from solutions in the presence of oxidizing additives on the surface of opaque and transparent substrates was performed upon laser irradiation at 532 nm. Organic alcohols such as ethanol and ethylene glycol were used as the reducing agents whereas potassium...

During gold extraction by cyanidation, fine gold particles encapsulated in sulfidic minerals are not readily extracted and carbonaceous matter can absorb aurocyanide complexes from the leaching solution. Therefore, high-sulfur and high-arsenic carbonaceous refractory gold ore cannot be treated e...

Male F344 rats were exposed to potassium bromate (KBrO3) in drinking water at concentrations of 0, 5, 20, 100, 200, or 400 mg/L for 2 or 13 weeks. Endpoints evaluated included clinical observations, body weights, serum chemistry, gross pathology, organ weights, and select tissue histopathology (...

ObjectiveTo investigate the effects of supplementation of potassium bromate (KBrO3) to drinking water on the growth rate, pubertal weight, testis & epididymal weights and testicular histology of growing male rats.

Potassium bromate (KBrO3) is widely used as a food additive and is a major water disinfection by-product. The present study reports the side effects of KBrO3 administration in Swiss mice. Animals were randomly divided into three groups: control, low dose KBrO3 (100 mg/kg/day) and high dose KBrO3...

SummaryThe effects of Curcuma longa rhizome on hepatic cells, glycogen, connective tissue fibres and filamentous cytoskeleton were evaluated following KBrO3-induced liver injury in Wistar rats. Thirty-five male rats were randomly divided into seven groups (n = 5). Group 1 were normal saline trea...

A novel and highly sensitive flow-injection chemiluminescence method for the determination of potassium bromate (KBrO3) has been developed. This method is based on the luminescence properties of the KBrO3–Na2SO3–quinine sulfate system in acid medium. Optimized experimental conditions and a pos...

ObjectiveThe current study aimed to elucidate the effect of vanillin on behavioral changes, oxidative stress, and histopathological changes induced by potassium bromate (KBrO3), an environmental pollutant, in the cerebellum of adult mice.

4-Amino-5,7-disubstituted pyridopyrimidines are potent, non-nucleoside inhibitors of adenosine kinase (AK). We recently identified a potent, orally efficacious analog, 4 containing a 7-pyridylmorpholine substituted ring system as the key structural element of this template. In this report, we di...

Thermolysis of (R*,S*)-(2-{[2,8-bis(trifluoromethyl)quinolin-4-yl](hydroxy)∼methyl}piperidin-1-ium) tetraphenylborate, (±)-erythro-mefloquinium tetraphenylborate, 3, in solution or neat, provides the oxazaborolidine derivative, diphenyl[(R*,S*)-(2,8-bis(trifluoromethyl)quinolin-4-yl)]piperidin...

1,3,5-tri-tert-butylbenzene (TTBB) is solid at ambient conditions, and has substantial solubility in liquid and supercritical carbon dioxide. We present the phase behavior of TTBB–CO2 binary system at temperatures between 298 and 328 K and at pressures up to 20 MPa. Phase diagrams showing the l...

The paper presents the structure and molecular correlations in liquid 1,3,5–tri-tert-butylbenzene C6H3[C(CH3)3]3 determined for the first time by the X-ray diffraction method. Experimental function i(S) was determined by X-ray scattering from a liquid sample and compared with the theoretical fu...

FT-IR and FT-Raman spectra of 1-hydroxy-4,5,8-tris(4-methoxyphenyl)anthraquinone were recorded and analyzed. The vibrational wavenumbers were computed using DFT quantum chemical calculations. The data obtained from wavenumber calculations were used to assign the vibrational bands obtained experi...
