(1988)The apparent permeation rate constants and amount of ranitidine transferred in 1 h were measured through everted rat intestine using a perfusion apparatus. The effects of pH and 5% or 10% ethanol on the apparent permeation ...
-
(1995)The synthesis, characterization and the reversible interaction with oxygen of a Cu(I)-mercaptoethylamine complex (I) in aqueous solution and room temperature is reported. As a result of the interaction with oxygen a violet ...
-
(2011)The adsorption of hydrophobically modified polyelectrolytes derived from poly(maleic anhydride-alt-styrene) (P(MA-alt-St)) containing in their side chain aryl-alkyl groups onto amino- or methyl-terminated silicon wafers ...
-
(1983)2-Hydroxy-3-(p-hydroxyphenyl)-6-methylpyrazine (HHMP) is identified as the product obtained by acidic degradation of amoxycillin in the presence of formaldehyde. I.R., n.m.r. and elemental analysis data are reported. The ...
-
(1992)Lifetimes of pyrene incorporated into large unilamellar vesicles of dipalmitoylphosphatidylcholine and dioctadecyldimethylammonium chloride increase when the temperature increases prior to the melting temperature of the ...
-
(1992)Partition constants for several aliphatic alcohols between water and micellar phases were determined using ultrafiltration and dialysis. Results indicated that the micellized concentrations of the long-chain alcohol followed ...

Cyclic voltammetric and EPR spectroscopic studies of benzodiazepines: Loprazolam and flunitrazepam (Elsevier, 1997)The present paper reports on the electrochemical characterization by cyclic voltammetry of two 1,4-benzodiazepines, loprazolam and flunitrazepam in protic, aprotic and mixed media. In protic media (ethanol + 15 mM citrate ...
-
(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 ...
-
Cyclic voltammetric study of the nitro radical anion from nitrendipine generated electrochemically (1991)Electrochemical studies on nitrendipine using mixed aqueous/dimethylformamide (DMF) solvent have allowed us to generate the one-electron reduction product, the nitro radical anion, RNO.-2. The voltammetric technique has ...
-
(1990)A new differential pulse polarographic method for the determination of buspirone pharmaceutical formulations is proposed. The method is based on the CN bond electroactivity of buspirone pirimidinic ring. Recovery study ...
-
(ESG, 2015)4-[3(5)-(4-aminophenyl) [1(2),2(2):2(5),3(2)-terthiophen]-1(5)-yl]benzonitrile (CB4TA), 4-[3(5)-(4-aminophenyl) [1(2),2(2):2(5),3(2)-terthiophen]-1(5)-yl]-2-nitrobenzonitrile (C2B4TA) and 4-[3(5)-(4-aminophenyl) ...
-
(1994)We have investigated the electrocatalytic activity of vitamin B12 adsorbed on ordinary pyrolytic graphite (OPG) for the oxidation of cysteine and glutathione and for the reduction of cystine, using cyclic voltammetry and ...
-
(1983)The a.c polarographic method has been applied in the study of the glutathione-ampicillin interaction at pH 7.4 and 37°C. Ampicillin shifted the peak potentials of glutathione to less negative values. A linear relation was ...
-
(1994)The cyclic voltammetric behavior of nicardipine was studied. Particular attention was directed to the one-electron ArNO2/ArNO2•- couple as measured by the cyclic voltammetric mode in aqueous DMF mixed media. Analysis of ...
-
(Elsevier Sequoia SA, 1999)The electrochemical reduction of a series of β-nitrostyrene and β-methyl-β-nitrostyrene derivatives by tast and differential pulse polarography and cyclic voltammetry over a wide pH range was studied. The reduction potentials ...
-
(Pergamon-Elsevier Science LTD, 2018)This work is focused on the critical analysis of the non-covalent modification of a thiolated-gold surface with different grapheneous materials and the covalent attachment of bovine serum albumin (BSA) as a model protein. ...
-
(1983)The interaction of glutathione with cloxacillin was investigated by a new a.c. polarographic procedure. The theoretical treatment used to describe the interaction is strongly consistent with the experimental results. The ...
-
(1983)The interaction of glutathione with ampicillin was investigated by a new a.c. polarographic procedure. Ampicillin was found to interact strongly with glutathione. The stability constants were ascertained from the polarographic ...
