-
(2005)A series of phenethylamine derivatives with various ring substituents and with or without N-methyl and/or C-alpha methyl or ethyl groups was synthesized and assayed for their ability reversibly to inhibit monoamine oxidase ...
-
(2003)Data is presented on the quenching of 9,10-dicyanoanthracene by benzene derivatives in acetonitrile. The quenching occurs via a charge transfer mechanism with the quenching rate constants exhibiting a Rehm-Weller dependence ...
-
(John Wiley and Sons Inc., 1999)The effect of the basicity of methyl-amines on hydrogen bonding (HB) with HCOOH is examined in both gas and solution phases. In the gas phase, the strength of HB may be related to the proton affinity (PA) difference between ...
-
(2003)Detection of singlet molecular oxygen, O2(1Δ g), by phosphorescence emission, λ = 1270 nm, following laser excitation was employed to measure the quantum yield of O2( 1δg) generation by the antimalaric drugs quinine, ...
-
(2005)The synthesis of a new class of angular tetracyclic quinones is described. Our strategy involves Diels-Alder reaction of pyrroloquinolinequinone 9, generated in situ from pyrroloquinoline 8, and dienes. The required ...
-
(2005)1,4-dihydropyridine derivatives constitute an important pharmacological group for the treatment of cardiovascular diseases. We have synthesised a series 4-(5′-nitro-2′-furyl)-1,4-dihydropyridine derivatives, which were ...
-
(2004)The pathway for the in vitro equilibrium unfolding of the tubulin heterodimer by guanidinium chloride (GdmCl) has been studied using several spectroscopic techniques, specifically circular dichroism (CD), two-photon ...
-
(2005)Phanerochaete chrysosporium has been thoroughly studied as a microbial model for lignin degradation. The enzymes lignin peroxidase (LiP) and manganese peroxidase (MnP), both encoded by several genes, play the main role in ...
-
(2002)Objetives: To compare endothelium-dependent vasomotor response in healthy younger and older subjects without classic cardiovascular risk factors, with high and normal fasting homocysteine (tHcy) levels. Design: We compared ...
-
(Wiley-VCH Verlag, 1998)Three types of tetrone radical anions in which two 1,4-benzoquinone units are connected by ethano (1·-, 2·-), [2.2]paracyclophane (3·-, 4·-), and anthracene bridges (5·-, 6·-) have been studied by ESR and ENDOR spectroscopy. ...
-
(2003)The formation of inclusion complexes of well-known 1,4-dihydropyridine calcium antagonists, such as nifedipine (NF) and nicardipine (NC), with beta-cyclodextrin (betaCD) was investigated by differential pulse polarography ...
-
(2004)Inclusion complexation between furnidipine (2,6-dimethyl-4-(2-nitrophenyl)-1,4-dihydropyridine-3,5-dicarboxylic acid 3-tetrahydrofurfuryl 5-methyl diester), a calcium-channel antagonist, and beta-cyclodextrin (beta-CyD) ...
-
(2001)Genetic analyses of the lignin-degrading fungus Ceriporiopsis subvermispora is complicated by a dikaryotic nuclear condition and the absence of spore forms. Previous investigations had identified a family of closely related ...
-
(Royal Soc of Chemistry, 1999)TXRF (total reflection X-ray fluorescence spectrometry), a rapid and reliable multi-element method, was applied to quantify intracellular concentrations of trace and non-trace elements in different mammalian cell lines. ...
-
(Elsevier Sci B.V., 1999)This communication describes the application of a hollow-fiber-type solid supported liquid membrane technique to the selective recovery and enrichment of copper from a Chilean mine water. The membrane extractor works by ...
-
(1997)A series of nitro aryl 1,4-dihydropyridine derivatives produced inhibition of both cell growth and oxygen consumption on Tulahuen and LQ strains, and clone Dm 28c of epimastigotes of Trypanosoma cruzi. Nicardipine was found ...
-
(2003)Potassium ferricyanide (Fe(CN)6]3-) reduction and ferrocenemethanol (Fc-OH) oxidation at a β-cyclodextrin (β-CD)-modified gold electrode were investigated by cyclic voltammetry (CV) and scanning electrochemical microscopy ...
-
(1997)The relationship between the metal-binding properties of metallothionein (MT) and its ability to interact with peroxides and free radicals was explored in vitro. The binding of 109Cd to MT and the thiol density of the ...
-
Systematic HPLC study of a new series of 4-methyl-1,4-dihydropyridines with antitrombotic activity (Marcel Dekker Inc., 1998)A systematic study of a new series of 4-methyl-1,4-dihydropyridine derivatives by HPLC by both photodiode array and electrochemical detectors is reported. The optimum mobile phase was acetonitrile/0.05 M phosphate buffer ...
-
(Taylor and Francis Inc., 1998)An analytical chromatographic method for the determination of nimesulide in pharmaceutical forms has been developed. The method is based on high performance liquid chromatographic (HPLC) and electrochemical detection. ...
