Recently, the full range dielectric spectrum of poly(2-hydroxyethyl methacrylate) was reported. This study looks at the effects on the dielectric...

AimsTo design and synthesize novel N-(1-phenyl-2,3-dihydroxypropyl)arachidonylamides and evaluate their analgesic and anti-inflammatory potential.

Self-assembled amphiphilic N-(2,3-dihydroxypropyl)–chitosan–cholic acid (DHP–CS–CHO) micelle was prepared as a carrier for paclitaxel. DHP–CS–CHO was synthesized by grafted small molecules cholic acid and glycidol onto primary amine group of chitosan, respectively. The DHP–CS–CHO formed ...

A novel synthesized reagent, O,O-bis(2,3-dihydroxypropyl) dithiophosphate (DHDTP), was investigated as depressant on the depression of chalcopyrite and galena, when ammonium dibutyl dithiophosphate (DDTP) was used as the collector in flotation tests. Zeta potential and adsorption measurement wer...

Sodium 2,3-dihydroxypropyl dithiocarbonate (SGX), which contains —OH and —CSS— in the molecule, was used to explore selective depression of galena from chalcopyrite in the flotation tests with ammonium dibutyl dithiophosphate (DDTP), and zeta potential and adsorption measurements were perform...

(4-Chlorophenyl)-(1-oxo-1λ4-benzo[b]thien-2-yl)methanone 2a was synthesized by oxidation of the corresponding benzo[b]thiophene derivative 2 with the oxidative system H2O2TFA. This benzo[b]thiophene sulfoxide undergoes Michael-type nucleophilic addition of sulfur- and oxygen-containing nucleoph...

New sorafenib derivatives containing thioether and nicotinamide moiety were designed and synthesized as B-Raf, B-RafV600E and VEGFR-2 multikinase inhibitors. Their in vitro enzymatic inhibitory activities against B-Raf, B-RafV600E and VEGFR-2 and their antiproliferative activities against HCT-11...

An efficient one-pot method for the synthesis of 2-sulfanyl-3-sulfinyl(or sulfonyl)-1H-indoles from 1-isothiocyanato-2-[sulfinyl(or sulfonyl)methyl]benzenes, derived from N-[2-(chloromethyl)phenyl]formamide by an easy four-step sequence, has been developed. The products are formed via cyclizatio...

2-Carboxy-4-hydroxy-α-tetralone (5) and its methyl ester (10) were incorporated into catalponol (1) in Catalpa ovata with retention of C-4 and C-8 tritium atoms. Incorporation of the former two substances into catalpalactone (2) and 4,9-dihydroxy-α-lapachone (12) was also demonstrated.

IM-5 zeolite was modified with different amounts of phosphorus species. The effect of the introduction of phosphorus into IM-5 zeolite (P-IM-5) was evaluated on the alkylation of toluene with methanol. The samples were characterized by X-ray diffraction, scanning electron microscopy, N2 physical...

Pru p 1 and Pru p 3 are proteins found in peach (Prunus persica (L.) Batsch), and they are members of the pathogenesis-related protein 10 (PR-10) and non-specific lipid transfer protein (nsLTP) families, respectively. They are the main allergens of peach. In this paper, we describe a quantitativ...

A kinetic study of the thermal decomposition of caesium permanganate confirms previous observations by P.J. Herley and E.G. Prout (J. Chem. Soc. (1959) 3300). Our scanning electron microscope, high magnification examination of the textures of product and of partially decomposed samples provides ...

We synthesized the DNA oligonucleotide containing a new cross-linkable 4-amino-2-oxo-6-vinyltriazine (AOVT) nucleobase analogue (Et-AOVT) and evaluated these properties. Our results of the cross-link assay and thermal denaturing assay of duplexes containing AOVT demonstrated that the additional ...

The sensible thermal heat storage mixture containing hydrated cobalt phosphate, anhydrous disodium hydrogen phosphate and sodium sulfate has been synthesized and characterized with different measurement techniques. The specific heat capacity was measured using Differential Scanning Calorimetry (...
