A low molecular weight lignin from various lignocellulosic materials was used for the synthesis of bio-based epoxy resins. The lignin extracted with methanol from steam-exploded samples (steaming time of 5 min at steam pressure of 3.5 MPa) from different biomasses (i.e., cedar, eucalyptus, and b...

NK-lysin is an anti-microbial and anti-tumor protein expressed by NK cells and T lymphocytes. In a previous report, we identified a set of overlapping expressed sequence tags constituting a contiguous sequence (contig 171) homologous to mammalian NK-lysins. In the current report, a cDNA encoding...

The active ingredients of Japanese green tea (Camellia sinensis) were utilized to synthesize bio-based epoxy resin. The catechin compounds in the aqueous extract of green tea were functionalized with epichlorohydrin under alkaline conditions in the presence of tetramethylammonium chloride (TMAC)...

ObjectiveTo explore the adsorption properties for the separation of apigenin from Viola yedoensis on LSA-10 resin.

ObjectivesThis study aimed to determine the biaxial flexural strength (BFS) of resin composite materials at distinct deformation rates.

The effect of pH, light, temperature and oxygen on the stability of dobupride (1), a novel gastroprokinetic drug, has been studied, storing the sample in the solid state and as a solution in methanol-water. The main forced degradation products have been identified by means of techniques such as ...

Tunable capacitors with up to 30% tuning and a loss tangent (tanδ) less than 0.002 at 1 MHz were fabricated from Ba0.6Sr0.4TiO3 (BST) films using inkjet-printed liquid metalorganic precursors. BST films of various thicknesses were produced by printing multiple stacks of the individual inkjet-pr...

A large sample of government-sponsored R&D consortia in Japan in analyzed, based on the data of 237 consortia organized over 34 years and 398 responses to questionnaires distributed to high-level corporate R&D managers who have participated in R&D consortia. My analysis shows that there is no cl...

1.1. Normal human and rat urine contain N-(3-aminopropyl)pyrrolidin-2-one. This compound was identified by its Chromatographic behaviour on a reversed phase column, by thin-layer chromatography of its dansyl derivative, and by mass spectrometry.2.2. Evidence for the presence of conjugates of N-(...

A capillary gas chromatographic method with mass spectrometric detection for the determination of N-(3-acetamidopropyl)pyrrolidin-2-one, the monoacetyl conjugate of isoputreanine-γ-lactam, in urine has been developed. Using a quantification based on stable isotope dilution mass fragmentography,...

IntroductionAs part of our program to develop estrogen receptor (ER) targeted imaging and therapeutic agents we chose to evaluate 11β-substituted estradiol analogs as a representative scaffold. Previous synthetic studies provided an entry into this class of compounds and other work indicated th...

A new series of 8-(substituted-phenyl)xanthines have been synthesized and compounds were evaluated for their affinity for A1 and A2 adenosine receptors (AR) using radioligand binding assays. The effects of varying the positions of 8-phenyl substituents on affinity and selectivity at A1 and A2A a...

As part of the search for tamoxifen substitutes that could be useful in the treatment of breast cancer, the use of organometallic complexes has been investigated. For this purpose a synthesis has been developed for ferrocifen, the prototype of this new series of complexes. Low valent titanium-me...

A series of E,E,E-3,5-bis(arylidene)-1-(4-arylamino-4-oxo-2-butenoyl)-4-piperidones 4 (phenylidene) and 5 (4-nitrophenylidene) were prepared in order to explore the structural features of the N-acyl group which affects the cytotoxic potency. Evaluation toward human Molt 4/C8 and CEM T-lymphocyte...

Two series of thieno[2,3-d]pyrimidine derivatives bearing a dithiocarbamate side chain at the C2 position were synthesized and evaluated for cytotoxic activity in human lung cancer A549 and colon cancer HCT-116 cell lines. Compound 3n exhibited the most cytotoxic effect on A549 cells with an IC5...

The mitogen-activated protein kinase-interacting kinases 1 and 2 (MNK1 and MNK2) phosphorylate eukaryotic initiation factor 4E (eIF4E) and play important roles in promoting tumorigenesis and metabolic disease. Thus, inhibiting these enzymes might be valuable in the treatment of such conditions. ...

The crystal and molecular structure and physicochemical properties of 2-N-methylamino-3-methylpyridine N-oxide (MA3MPO) have been studied. MA3MPO was synthesized from 2-amino-3-methylpyridine by several steps to form colorless crystals suitable for crystallographic analysis. The data reveal that...

Electronic absorption spectra of 2-ethylamino-3-methyl-4-nitropyridine and 2-ethylamino-5-methyl-4-nitropyridine in the solid state and ethyl alcohol solution have been measured at room temperature. Their luminescence spectra and life times have been recorded at room and liquid helium temperatur...

The chelate complex [CuCl2(L)] where L = 2-methylamino-3-methyl-4-nitropyridine-N-oxide has been obtained and characterized, both physicochemically (by the X-ray structure analysis of the complex and the ligand, FTIR, EPR and electronic spectroscopy, and thermal analysis) and cytotoxically (MCF-...
