In this work, some 2-nonsubstituted/2-methyl-/2-(2-acetyloxyethyl)-6-[4-(substituted pyrrol-1-yl)phenyl]-4,5-dihydro-3(2H)-pyridazinone, derivatives and 2-nonsubstituted/2-methyl- 4-[4-(substituted pyrrol-1-yl)phenyl]-1(2H)-phthalazinone derivatives were synthesised by reacting hexan-2,5-dion or 1-aryl-3-carbethoxypent-1,4-diones with corresponding 2-substituted/nonsubstituted 6-(4'-aminophenyl...

Healthy subjects ingested2H2O.2H enriched the hydrogen bound to carbon 1 of blood glucose 1.3 to 1.8 times more than the hydrogens bound to carbon 6. Enrichment at carbon 1 was more than at carbon 5 after 14 h, but not after 42 h, of fasting. After overnight fasting, when [2,3-3H]succinate was infused, 34 times as much 3H was bound to carbon 6 as to carbon 1. On [1-2H,1-3H,1-14C]galactose infus...

Water deuteron (2H) spin relaxation was used to study hydrogen exchange, hydration, and protein dynamics in aqueous solutions of the globular proteins bovine pancreatic trypsin inhibitor (BPTI) and ubiquitin. The frequency dispersion of the longitudinal 2H relaxation rate was measured in the pD range 2 to 11 at 27 degrees C. In contrast to the previously reported water 17O relaxation dispersion...

192 words) Objective: The most common screening tests for glucose intolerance are fasting plasma glucose (FPG) and glycated hemoglobin (HbA1c). Because it reflects the current status of hyperglycemia, urinary myo-inositol (UMI) may be useful. We evaluated UMI as a screening tool for glucose intolerance. Design and Methods: A cross-sectional, community-based population study of 1057 Japanese res...

High field deuterium NMR spectra have been recorded for various horseradish peroxidase complexes reconstituted with hemins possessing specific 2H labels. The line width of the 2H NMR signals of deuteroheme reconstituted-horseradish peroxidase (HRP) and its cyano complex for the immobilized skeletal 2-2H and 4-2H labels yield the overall protein rotational correlation time (22 ms at 55 degrees C...

The in vivo metabolism of an antiallergic agent, azelastine, (4-(p-chlorobenzyl)-2-[Nmethylperhydroazepinyl-(4)]-l-(2H)-phthalazinone hydrochloride) was examined following oral administration to rats and guinea pigs. As a result, it was found that the drug was metabolized to 4-(p-chlorobenzyl)-2-[N-methyl-7-oxo-perhydroazepinyl-(4)]l-(2H)-phthalazinone, 6-hydroxy-4-(p-chlorobenzyl)-2-[N-methylp...

We developed EST-PCR markers specific to barley chromosome 2H, for the purpose of effectively tracing alien chromosomes or chromosome parts in the wheat genetic background. The target alien chromosome 2H confers high resistance to pre-harvest sprouting, which is a worldwide natural disaster in wheat. A total of 120 primer pairs were selected by combining the wheat group 2 chromosomes of th...

Reaction of methyl-2-(2-formylphenyl)acetate with primary amines in a reductive amination/cyclisation process resulted N-substituted 1,4-dihydro-3(2H)-isoquinolinones. With H2NCH2R sodium borohyride is suitable reductant (11 examples), but H2NCHR1R2 required transfer hydrogenation using ammonium formate catalysed by palladium on carbon (9 examples). 4-Substituted-1,4-dihydro-3(2H)-isoquinolinon...

BACKGROUND Coumarin and their derivatives are important and useful compounds with diverse pharmacological properties. In the present study, we evaluated the in vitro cytotoxic activity of new acetoxycoumarin derivatives: 4-(7-methoxy-4-methyl-2-oxo-2H-chromen-3-yl)phenyl acetate (1), 4-(1-methyl-3-oxo-3H-benzo[f]chromen-2-yl)phenyl acetate (2), 4-(6-propionamido-4-methyl-2-oxo-2H-chromen-3-yl) ...

sound transducer 24 mm in diameter and piezoelectrically active at both 1.0 & 2.0 MHz was used. Acoustic emission from 10% ethyl alcohol solutions were measured during insonation at acoustic intensity of 10 W/cm2 (1.0 & 2.0 MHz: 5 W/cm2 each) and the intensity of a subharmonic component at 0.5 MHz was calculated. SH phase shifting with a shift pitch not larger than 0.5 π and a shift interval ti...
