We describe the use of aromatic ketones and cinnamyl ketones that have high vacuum stability for analyzing tissue sections using matrix-assisted laser desorption/ionization imaging mass spectrometry. Specifically, the matrix, (E)-4-(2,5-dihydroxyphenyl)but-3-en-2-one (2,5-cDHA) provides high sensitivity and high vacuum stability while producing...

Patch-clamp techniques were used to study the effects of three carbonyl compounds, 3,4-dihydroxybenzaldehyde, 2,3-dihydroxybenzaldehyde, and 2,4-dihydroxyacetophenone, on the adenosine-5'-triphosphate(ATP)-sensitive K+ channel current (IK.ATP) in guinea-pig ventricular myocytes. 3,4-Dihydroxybenzaldehyde (0.5-1 mM) shortened the action potential duration, and this effect was inhibited...

To confirm the proposed structures of the minor metabolites of a potential gastroprokinetic agent, mosapride, 4-amino-5-chloro-2-ethoxy-3-hydroxy-N-(2-morpholinylmethyl)benzamide (3) and the N-(5-oxo-2-morpholinyl)-methyl analogue 4 were prepared. As the common intermediate, 2-ethoxy-3-hydroxy-4-nitrobenzoic acid (15) was prepared via the regioselective ethylation of 2,3-dihydroxybenzaldehyde (10)...

In the present work, a graphene encapsulated ZnO/Co3O4 (GE/ZnO/Co3O4) core-shell hybrid is fabricated through a facile self-assembly approach, where the mutual electrostatic interaction force drives the ZnO/Co3O4 heteronanostructures to be fully wrapped with flexible ultrathin graphene shells. The as-prepared GE/ZnO/Co3O4...

To study the chemical constituents of Elaeocarpus sylvestris. The compounds were isolated by chromatographic methods and their structures were elucidated by physico-chemical properties and spectral analysis. Six compounds were isolated and identified as: 2-hydroxy-benzaldehyde (1), coniferyl alcohol (2), umbelliferone (3)...

Tolerance of human pathogenic fungi to antifungal drugs is an emerging medical problem. We show how strains of the causative agent of human aspergillosis, Aspergillus fumigatus, tolerant to cell wall-interfering antimycotic drugs become susceptible through chemosensitization by natural compounds. Tolerance...

Activities of conventional antifungal agents, fludioxonil, strobilurin and antimycin A, which target the oxidative and osmotic stress response systems, were elevated by coapplication of certain benzo analogs (aldehydes and acids). Fungal tolerance to 2,3-dihydroxybenzaldehyde or 2,3-dihydroxybenzoic acid was found to...

We have screened toyocamycin as an inhibitor of phosphatidylinositol kinase. It inhibited the enzyme of A431 cell membrane with an IC50 of 3.3 micrograms/ml. Adenosine and formycin A also inhibited the enzyme, but other 6 related nucleosides did not. Although...

Reversible 2,6-dihydroxybenzoate decarboxylase from Rhizobium sp. strain MTP-10005 belongs to a nonoxidative decarboxylase family. We have determined the structures of the following three forms of the enzyme: the native form, the complex with the true substrate (2,6-dihydroxybenzoate), and the complex...

Under anaerobic conditions, xanthine oxidase (XO)-catalyzed nitrite reduction can be an important source of nitric oxide (NO). However, questions remain regarding whether significant XO-mediated NO generation also occurs under aerobic conditions. Therefore, electron paramagnetic resonance, chemiluminescence NO-analyzer, and NO-electrode studies...
