The degradation of veratraldehyde by Alcaligenes paradoxus was studied. Three products, veratric acid, vanillic acid and a minor amount of veratryl alcohol, were identified. The effect of various metabolic inhibitors on the uptake of veratraldehyde, veratric and vanillic acid showed the uptake p...

Seven new 4-hydroxybenzyl-substituted amino acid derivatives (1−7), together with 11 known compounds, were isolated from an aqueous extract of the rhizomes of Gastrodia elata Blume. Their structures were determined by spectroscopic and chemical methods. Compounds 1−3 are pyroglutamate derivative...

Racemic 8-ethoxy-2-(4-fluorophenyl)-3-nitro-2H-chromene (S14161) was recently identified as a potent inhibitor of phosphoinositide 3-kinase (PI3K). In order to investigate the effects of its two enantiomers on tumor cell lines, we designed a novel synthesis for (R)-S14161 and (S)-S14161 using a ...

Activated carbon was prepared from palm shell agro waste by chemical activation method using Potassium hydroxide. Nano-magnesium oxide was green synthesized using neem leaf extract by rapid precipitation method. Nano-magnesium oxide impregnated onto palm shell activated carbon composite was prod...

This paper presents a study of the removal of anthracene from a clay soil using a surfactant and investigates the effects of electric field on the anthracene removal efficiency. A non-ionic surfactant, Tween 80, was fed to the anode reservoir and the tests were conducted under voltage gradient o...

Anthracene (CAS RN: 120-12-7) is recommended as a primary standard for sublimation enthalpy measurements and it is also frequently used for testing apparatus for vapour pressure measurements. Two recent recommendations by ICTAC for sublimation enthalpy at 298.15 K obtained by extrapolation can b...

Polycyclic aromatic hydrocarbons (PAHs) were identified as hazardous contaminants that are ubiquitous and persistent in aquatic environments, where bryophytes sensu lato (mosses, liverworts and hornworts) are frequently present. Marchantia polymorpha (Class Hepaticae; thalloid liverwort) is know...

This paper reports an electrochemical method for the detection of trace anthracene in waters, based on glassy carbon electrode surfaces functionalized with a molecular imprinted polymer. The electropolymerization of the pyrrole monomer was carried out by cyclic voltammetry in ethanol containing ...

The electronic structures of 9,10-dimethylanthracene (DMA) and its photodimer: di-paraanthracene (DA) have been studied in the gas phase by UV photoelectron spectroscopy and quantum chemical calculations. The comparison of the spectrum of DA with the spectrum of 9,10-dihydroanthracene (DHA) show...

A quinazoline derivative 6-anthracenyl-5,6-2H-benzimidazo[1,2-c]quinazoline (L) was obtained and characterized by elemental analysis, IR spectroscopy, 1H NMR and single-crystal X-ray diffraction. L shows very weak emission in DMSO, but can respond to Hg2+ ion intensively in off-on mode. Job'...

Two anthracene bridged triphenylamine sensitizers TPAA6 and TPAA7 were designed, synthesized and used as potential candidates for dye-sensitized solar cells. Investigations on structure-property relationship, photophysical, electrochemical and device dynamics were explored in detail. Absorption ...

A reaction of 3-arylcyclobutanones with anthracene in the presence of TiCl4 gave 14-aryl-9,10-dihydro-9,10-butanoanthracen-12-ones as a formal [4 + 4] cycloadduct of anthracenes with a C4 unit formed by cleaving the more substituted C2C3 bond of cyclobutanones. On the other hand, activation of 3...

Scoparone, one of the bioactive components of Artemisia capillaris Thunb, has various biological properties including immunosuppressive, hepatoprotective, anti-allergic, anti-inflammatory, and antioxidant effects. This study aims at evaluating the anti-osteoporotic effect of scoparone and its un...

This study was performed to investigate the effect of scoparone on the differentiation of 3T3-L1 preadipocytes. Scoparone inhibited triglyceride (TG) accumulation in the mature adipocytes, evidenced by Oil-red O staining and intracellular quantification. Real time-PCR analysis showed that scopar...

The effects of scoparone on dopamine release in PC12 cells were investigated. Scoparone at 50–200 µM increased dopamine release into the culture medium. However, the released levels of dopamine by scoparone were not altered in the absence of extracellular Ca2+ and by adenylyl cyclase inhibitor...

The purpose of this study was to investigate the protective effects and molecular mechanisms of scoparone on lipopolysaccharide (LPS)-induced acute lung injury in mice. Mice model of acute lung injury (ALI), induced by intranasal instillation of LPS, was used to investigate the protective effect...

Activation of hepatic stellate cells (HSCs) plays a critical role in liver fibrosis. Scoparone, a major constituent isolated from Artemisia capillaris, was reported to possess hepatoprotective effect. However, the role of scoparone in liver fibrosis remains unknown. In the present study, we inve...
