- W1983991668 abstract "Separation of racemic amino drugs (α-methylbenzeneethanamine, 6-amino-2-methyl-2-heptanol and 1-aminoethyl-benzenemethanol) and thiol drugs [N-(2-mercapto-1-oxopropyl) glycine, 2-mercaptopropanoic acid, and N-acetyl-3-mercaptovaline] has been evaluated after derivatization. ortho-Phthalaldehyde (OPA) and naphthalene-2,3-dicarboxaldehyde (NDA) were used with either homochiral thiols (N-acetyl-L-cysteine and N-acetyl-D-penicillamine) or amines [(-)-(1R,2S)-norephedrine, L-phenylalanine, L-tyrosine, and 3-hydroxy-L-tyrosine] as chiral selectors according to the analyte reactive group. The resulting 36 diastereoisomeric derivatives were studied using reversed-phase high-performance liquid chromatography (RP-HPLC) and capillary electrophoresis (CE). Of the CE modes, micellar electrokinetic chromatography (MEKC) using sodium dodecyl sulfate (SDS) as surfactant, β-cyclodextrin (β-CD)-modified capillary zone electrophoresis (β-CD-CZE), and β-CD-MEKC were applied. Results highlight respective performance of the reagents and separative techniques. All OPA derivatives of racemic amino drugs were resolved either by MEKC or β-CD-MEKC. In the case of racemic thiol drugs, 10 of the 12 OPA derivatives were resolved in β-CD-CZE. © 1995 Wiley-Liss, Inc." @default.
