Chiral analysis of bambuterol, its intermediate and active drug in human plasma by liquid chromatography-tandem mass spectrometry: Application to a pharmacokinetic study.

Ting Zhou et al.

Journal of chromatography. B, Analytical technologies in the biomedical and life sciences, 997, 38-44 (2015-06-21)

A sensitive liquid chromatography-tandem mass spectrometry (LC-MS/MS) method has been developed for simultaneous chiral analysis of an antiasthma drug bambuterol, its key intermediate monocarbamate bambuterol and its active drug terbutaline in human plasma. All samples were extracted with ethyl acetate

Enantiomeric separation of mirtazapine and its metabolite in rat plasma by reverse polar ionic liquid chromatography using fluorescence and polarimetric detectors connected in series

Rao, R. Nageswara, et al.

Journal of Chromatography. B, Biomedical Sciences and Applications, 879 (21), 1911-1916 (2011)

Effect of the mobile phase on the retention behaviour of optical isomers of carboxylic acids and amino acids in liquid chromatography on bonded Teicoplanin columns.

P Jandera et al.

Journal of chromatography. A, 917(1-2), 123-133 (2001-06-14)

Conditions for separation of enantiomers of underivatized amino acids phenyl glycine and tryptophan and of mandelic acid as test compounds were studied on a Chirobiotic T column packed with amphoteric glycopeptide Teicoplanin covalently bonded to the surface of silica gel.

Amphetamine concentrations in human urine following single-dose administration of the calcium antagonist prenylamine-studies using fluorescence polarization immunoassay (FPIA) and GC-MS.

Thomas Kraemer et al.

Journal of analytical toxicology, 27(2), 68-73 (2003-04-03)

Prenylamine (R,S-N-(3,3-diphenylpropyl-methyl-2-phenethylamine), a World Health Organization class V calcium antagonist, is known to be metabolized to amphetamine. In this study, amphetamine concentrations after a single-dose administration of prenylamine were determined to check if they reached values that could be of

Comparison of vancomycin-based stationary phases with different chiral selector coverage for enantioselective separation of selected drugs in high-performance liquid chromatography.

Z Bosáková et al.

Journal of chromatography. A, 1088(1-2), 94-103 (2005-09-01)

Two vancomycin-based chiral stationary phases (CSPs) with different coverage of the chiral selector vancomycin (Chirobiotic V and Chirobiotic V2) were compared. beta-Blockers and profens, as structurally diverse groups of drugs, were chosen as analytes. Retention and enantioseparation of beta-blockers were

HPLC separation technique for analysis of bufuralol enantiomers in plasma and pharmaceutical formulations using a vancomycin chiral stationary phase and UV detection

Hefnawy, Mohamed M., et al.

Journal of Chromatography. B, Biomedical Sciences and Applications, 856 (1-2), 328-336 (2007)

Analysis of the enantiomers of citalopram and its demethylated metabolites using chiral liquid chromatography

Kosel, M., et al.

Journal of Chromatography. B, Biomedical Applications, 719 (1-2), 234-238 (1998)

Chiral separation by simultaneous use of vancomycin as stationary phase chiral selector and chiral mobile phase additive.

Q Sun et al.

Journal of chromatography. B, Biomedical sciences and applications, 745(1), 159-166 (2000-09-21)

Improved chiral selectivity was observed for numerous compounds when vancomycin was added to the mobile phase on a Chirobiotic-V column. This chiral mobile phase additive (CMPA) is the same chiral selector as that bonded to the stationary phase of this

Classification of LC chiral stationary phases: Wainer Types I?V revisited

Lough, W. John

Journal of Chromatography. B, Biomedical Applications, 968, 1-7 (2014)

A validated LC method for the determination of vesamicol enantiomers in human plasma using vancomycin chiral stationary phase and solid phase extraction.

Mohamed M Hefnawy et al.

Journal of pharmaceutical and biomedical analysis, 35(3), 535-543 (2004-05-13)

An enantioseparation high performance liquid chromatographic (HPLC) method was developed and validated to determine D-(+)- and L-(-)-vesamicol in human plasma. The assay involved the use of a solid phase extraction for plasma sample clean up prior to HPLC analysis utilizing
