A L Peyton et al.
Pharmaceutical research, 8(12), 1528-1532 (1991-12-01)
A quantitative method for the simultaneous HPLC resolution and detection of the enantiomers of (R,S) fluoxetine (F) and their metabolites (R,S) norfluoxetine (N) in human plasma has been developed. F is a serotonin uptake inhibitor used in the treatment of

Pharmaceutical research, 8(9), 1195-1198 (1991-09-01)
A convenient high-performance liquid chromatographic (HPLC) assay was developed for determination of sotalol (STL) enantiomers in plasma. Following addition of the internal standard (IS; racemic atenolol), enantiomers of STL and IS were extracted using ethyl acetate. After evaporation of the

A sensitive, stereospecific high-performance liquid chromatographic assay for oxprenolol enantiomers in rat plasma was developed, using a chiral derivatization agent. Racemic oxprenolol and the internal standard (racemic propranolol) are extracted with dichloromethane after alkalinization of the plasma. Quantitation of R(+)-

A sensitive high-performance liquid chromatographic assay was developed for the determination of tocainide enantiomers in plasma. Following extraction of tocainide from plasma, the enantiomers were derivatized with S-(+)-1-(1-naphthyl)ethylisocyanate. The resulting diastereomers were separated and quantified using normal-phase chromatography with fluorescence
D S Dunlop et al.
Analytical biochemistry, 165(1), 38-44 (1987-08-15)
A method for determining the optical purity of amino acids using HPLC and precolumn derivatization is described. (+)-1-(1-Naphthyl)ethyl isocyanate reacts with racemic amino acids, in high yield, to form naphthylethyl carbamoyl derivatives. The resulting diastereoisomeric pairs were separated on reversed-phase
