Poly(ethylene dimethacrylate-glycidyl methacrylate) monolith as a stationary phase in dye-affinity chromatography
(American Chemical Society, 2004)Porous monolith was obtained by the bulk polymerization of ethylene dimethacrylate (EDMA) and glycidyl methacrylate (GMA) conducted in a glass tube. Poly(EDMA-GMA) monolith had a specific surface area of 98.7 m(2)/g. ... -
Polymer-clay nanocomposite iron traps based on intersurface ion-imprinting
(American Chemical Society, 2008)We combined the ion-imprinting technique and the binding ability of Fe3+ ions to organosmectite to create the inorgano-organo Fe3+ ions imprinted polymer-nanocomposite traps with the goal of preparing a solid phase that ... -
Quinolone-Hydroxyquinoline Tautomerism in Quinolone 3-Esters. Preserving the 4-Oxoquinoline Structure To Retain Antimalarial Activity
(American Chemical Society, 2015)Recent publications report in vitro activity of quinolone 3-esters against the bc(1) protein complex of Plasmodium falciparum and the parasite. Docking studies performed in silica at the yeast Q(o) Site established a key ... -
Selective removal of bilirubin from human plasma with bilirubin-imprinted particles
(American Chemical Society, 2007)The objective of this study is to prepare bilirubin-imprinted polymeric particles for the selective removal of bilirubin from hyperbilirubinemic human plasma. N-methacryloyl-(L)-tyrosine methylester (MAT) was chosen as the ... -
Spectroscopic Determination of Acid Dissociation Constants of N-Substituted-6-acylbenzothiazolone Derivatives
(American Chemical Society, 2011)The acid dissociation constants of twelve novel drug precursor N-substituted-6-acylbenzothiazolone derivatives were determined by using the UV-vis spectroscopic technique. The protonation and deprotonation behaviors of the ... -
Spectroscopic determination of acid dissociation constants of some imidazole derivatives
(American Chemical Society, 2001)The acid dissociation constants, pK(a), of eight biologically active imidazole derivatives were determined using a spectroscopic technique. Using the obtained acid dissociation constants, attempts were made to elucidate ... -
Spectroscopic Determination of Acid Dissociation Constants of Some Novel Drug Precursor 6-Acylbenzothiazolon Derivatives
(American Chemical Society, 2010)The acid dissociation constants, as pK(a) values, of eight drug precursor 6-acylbenzothiazolon derivatives were determined using UV-vis spectroscopic technique. The protonation and deprotonation behaviors of the investigated ... -
Spectroscopic determination of acid dissociation constants of some pyridyl Shiff bases
(American Chemical Society, 2006)The acid dissociation constants (pK(a)) of eight biologically active pyridyl Shiff bases were determined using a UV-vis spectroscopic technique at 25 +/- 0.1 degrees C. The first acidity constants (pK(a1)) of the ... -
Spectroscopic determination of acid dissociation constants of some pyridyl-substituted 2-aminothiazole derivatives
(American Chemical Society, 2006)The acid dissociation constants, K-a, of nine biologically active 2-amino-4-(x-pyridyl)- thiazole, 2-methylimino-3-methyl- 4-(x-pyridyl)- 2,3-dihydrothiazole, and 2-methylamino-4-(x-pyridyl)- 2,3-dihydrothiazole were ... -
Spectroscopic determination of acidity constants of some monoazo resorcinol derivatives
(American Chemical Society, 2008)The acidity constants, as pK(a) values, of six monoazo resorcinol derivatives were determined by the UV-visible spectroscopic technique at 25 degrees C (+/- 0.1 degrees C). The protonation and deprotonation behaviors of ... -
Spectroscopic Determination of the Acid Dissociation Constants of Some 2-Hydroxy Schiff Base Derivatives
(American Chemical Society, 2011)In this study the acidity constants of a series of biologically active pyridyl Schiff bases were calculated from UV-visible spectrophotometric data at (25 +/- 0.1)degrees C. The first acidity constants (pK(a1)) of the ... -
Structure and Photochemistry of N-Salicylidene-p-carboxyaniline Isolated in Solid Argon
(American Chemical Society, 2015)Infrared matrix isolation spectroscopy and DFT/B3LYP/6-311++G(d,p) calculations have been used to characterize the conformational space of the enol-imine and keto-amine tautomers of N-salicylidene-p-carboxyaniline (SCA) ... -
Thermal and Photoinduced Control of Relative Populations of 4-Methoxybenzaldehyde (p-Anisaldehyde) Conformers
(American Chemical Society, 2010)Two almost isoenergetic conformers of 4-methoxybenzaldehyde (p-anisaldehyde), O-trans and O-cis, are nearly equally populated in gas phase at room temperature. The existence of these two conformers of similar energy makes ...
