A radiolabeled amino acid O-[18F]fluoromethyl-D-tyrosine (D-[18F]FMT) has been reported to show high tumor uptake. However, introduction of [18F]fluoromethyl group was difficult and was an issue to be solved. We solved it by using a precursor containing 1,2,3-triazolium salt. D-[18F]FMT was synt...

Unexpected reaction pathways have been unravelled that are involved in the generation of 2,2,5,5-substituted tetrahydrofurans from the mesylate of 5-hydroxy-5-methyl-6-oxo-2-phenyl-2-piperidinemethanol (7). Upon treatment of 7 with amines under controlled conditions two reactive intermediates co...

In vitro rat hepatic microsomal metabolism of ten individual dichlorobiphenyls (DCBs) has been investigated as part of a major study of the role of metabolism in the toxicity of polychlorinated biphenyl (PCB) pollutant mixtures. The DCBs were metabolized to monohydroxy and dihydrodiol metabolite...

Human rhinoviruses (HRVs) are the most common cause of viral respiratory infections and their complications. So far, no anti-viral agent has been approved for prevention or treatment of HRV infections. Pursuing our researches on small molecules with anti-rhinovirus activity, in this paper we des...

Magnesium and aluminium phthalocyanines tetrasubstituted with 2-(dimethylamino) ethanethiol have been synthesized (complexes 2 and 3). The prepared complexes were converted to water soluble ones by quaternizing with methyl iodide. The quaternized complexes (2Q, 3Q) show monomeric behaviour in or...

The excess molar enthalpies of N,N-dimethylethanolamine (DMEA) + 1,4-dioxane, +DMF, +DMA or + DMSO at 298.15 K have been measured with a Picker microcalorimeter. Excess enthalpies for DMEA with DMF, DMA or DMSO are negative over the entire composition range except for 1,4-dioxane. Density measur...

The hydrogen-bond molecular interactions and molar ratio of stable adduct in binary mixtures of N,N-dimethylethanolamine with alcohols (ethyl alcohol, ethylene glycol, glycerol) and amides (formamide, N,N-dimethylformamide, N,N-dimethylacetamide) have been investigated over the entire concentrat...

This work presents atmospheric density and viscosity values for (N,N-dimethylethanolamine + water) over the entire composition range from T = (293.15 to 363.15) K for density and from T = (313.15 to 353.15) K for viscosity. Density measurements come from a vibrating tube densimeter while we have...

The physical solubility and mass transfer performance of CO2 absorption into aqueous N,N-dimethylethanolamine (DMEA) solution were comprehensively studied in the present work. The physical solubility (Henry’s law constant (He)) was measured using a stirred cell reactor for pure DMEA and aqueous...

CO2 absorption performance for various blended N,N-dimethylethanolamine (DMEA) solutions in the presence of absorption promoters including Monoethanolamine (MEA), Piperazine (PZ), 2-(Ethylamino)ethanol (EAE), 2-(Methylamino)ethanol (MAE) and 2-Amino-2-methyl-1-propanol (AMP) was investigated in ...

Li metal batteries have attracted many attentions owing to their excellent nature, including easier processes and higher energy density than that of conventional Li-ion batteries. However, lithium whiskers often result in the instability of Li anode and electrolyte, and even short circuit, which...

A series of complexes containing dmen (dmen = N,N-dimethylethylenediamine) units and cyano groups, namely bimetallic octanuclear and binuclear [Zn4(dmen)8Ni4(CN)16] (1), [Cd4(dmen)8Ni4(CN)16] (2), [Zn(dmen)2Pd(μ-CN)2(CN)2] (3) and [Cd(dmen)2Pd(μ-CN)2(CN)2] (4), have been synthesized and charac...

SiO2 thin films were successfully deposited by plasma-enhanced atomic layer deposition (PEALD) using a divalent Si precursor (N,N′-tert-butyl-1,1-dimethylethylenediamine silylene) and oxygen plasma as reactants. The growth behavior of SiOx exhibited the typical self-limiting surface reaction de...

DNL-6, a silicoaluminophosphate (SAPO) molecular sieve with RHO topology, was hydrothermally synthesized using a new structure-directing agent (SDA), N,N′-dimethylethylenediamine. The obtained samples were characterized by X-ray diffraction, X-ray fluorescence, X-ray photoelectron spectroscopy,...

Incubation of L1210 murine leukemia cells in vitro with 10 μM of the bifunctional alkylating agent bis(2-chloroethyl)methylamine (nitrogen mustard, HN2) for 10 min brought about a fall of more than 99.9% in their ability to form colonies when the cells were suspended in 0.5% nutrient agar. Incu...

Vapour pressures for 1-methoxy-2-propanol are reported as well as the vapour–liquid equilibrium data in the two binary 2-propanol + 1-methoxy-2-propanol, and diisopropyl ether + 1-methoxy-2-propanol systems, and in the ternary 2-propanol + diisopropyl ether + 1-methoxy-2-propanol system. The da...

Some interesting features have been observed when 1-methoxy-2-propanol was studied in direct liquid fuel cells. Air flow rate ranging from 180 to 920 ml/min had no effect on performance, but the performance increased largely when the cell temperature was increased from 40, to 60, and then to 80 ...

The addition of propylene oxide with methanol was carried out over solid bases and a detailed mechanism of the reaction over MgO was investigated by using FT-IR method. It was found that 1-methoxy-2-propanol could be selectively synthesized on MgO, which had base sites of moderate strength, whil...

At the end of a workweek 23 silkscreen printers gave a urine sample for capillary gas chromatographic analysis for 1,2-propanediol.
