Challenges and innovations in chiral drugs in an environmental and bioanalysis perspective
(2021-09-01)
The boundary of the chiral environmental, forensic and bioanalysis has been critically presented in this review. Important advances regarding chiral screening technology and their impact on method development and applications ...
Resolution and Absolute Configuration Assignment of a Natural Racemic Chromane from Peperomia obtusifolia (Piperaceae)
(Wiley-liss, 2009-10-01)
The resolution of the natural racemic chromane 3,4-dihydro-5-hydroxy-2,7-dimethyl-8-(3 ''-methyl-2 ''-butenyl)-2-(4'-methyl-1',3'-pentadienyl)-2H-1-benzopyran-6-carboxylic acid (1) isolated from the leaves of Peperomia ...
Enantioselective Analysis of Fluoxetine and Norfluoxetine by LC in Culture Medium for Application in Biotransformation Studies Employing Fungi
(VIEWEG, 2009)
A liquid chromatography method is described for the analysis of fluoxetine and norfluoxetine enantiomers in fungi cultures. The analytes were separated simultaneously by LC employing a serial system. The resolution was ...
Enantioseparation of -amino acids by means of Cinchona alkaloids asselectors in chiral ligand-exchange chromatography
(Elsevier Science, 2013-07)
A conventional nonchiral column was used for the enantioseparation of several racemic -amino acids (native and derivatized) through the use of Cinchona alkaloids as chiral selectors along with Cu(II) ions in chiral ...
Enantioseparation of polar pesticides on chiral capillary columns based on permethyl-β-cyclodextrin in matrices of different polarities
(Elsevier Science, 2018-07)
This work describes the influence of different achiral polymers used to dissolve permethyl-β-cyclodextrin (PM-β-CD) on the gas chromatographic enantioresolution of racemic mixtures of polar pesticides (mecoprop, dichlorprop, ...
Chiral separation of several pesticides on an immobilized amylose tris(3-chloro-5-methylphenylcarbamate) column under polar-organic conditions: influence of mobile phase and temperature on enantioselectivity
(Elsevier, 2020-08)
In this work, the use of different solvents and temperatures was explored, aiming to evaluate their influence on the enantioseparation of pesticides by HPLC in polar-organic conditions, employing a column containing ...
Chiral ligand-exchange chromatography with Cinchona alkaloids. Exploring experimental conditions for enantioseparation of α-amino acids
(Elsevier Science, 2016-11)
The natural Cinchona alkaloid quinidine as chiral selector in chiral ligand-exchange chromatography was systematically studied. Chromatographic conditions for enantioseparation of twentya-amino acidswere first timestudied ...
