چکیده

Várias fases estacionárias baseadas em derivados de polissacarídeos e proteínas foram avaliadas para a resolução de alguns fármacos quirais e seus metabólitos. As fases estacionárias baseadas em polissacarídeos CHIRALCEL OD-H, CHIRALCEL OB-H, CHIRALCEL OJ, CHIRALPAK AD e CHIRALPAK AS foram avaliadas em condições de fase normal, usando hexano:2-propanol como fase móvel. Dietilamina ou ácido trifluoracético foram adicionados para melhorar a simetria dos picos. As colunas CHIRALCEL OJ-R, CHIRALCEL OD-R e CHIRALCEL OD-H foram avaliadas em condições de fase reversa, usando acetonitrila:água ou acetonitrila: NaClO 4 . As fases estacionárias baseadas em proteínas CHIRAL AGP e ULTRON ES-OVM foram usadas com fases móveis consistindo de soluções tampão adicionadas de modificadores orgânicos. Entre as fases estacionárias baseadas em derivados de polissacarídeos, a CHIRALPAK AD mostrou melhor resolução de quase todos os fármacos e metabólitos estudados. A coluna ULTRON ES-OVM foi particularmente útil para a resolução dos quatro estereoisômeros da tioridazina-2-sulfóxido.

Review High-performance liquid chromatographic enantioseparation of drugs containing multiple chiral centers on chiral stationary phases

In recent years there has been considerable interest in the synthesis and separation of enantiomers of organic compounds especially because of their importance in the biochemistry and pharmaceutical industry. High-performance liquid Chromatography is a very useful method for the direct separation of enantiomers. However, about 30−40 years ago, commercially available chiral stationary phases wer...

Chiral recognition mechanisms of four β-blockers by HPLC with Amylose Chiral Stationary Phase

The high performance liquid chromatography (HPLC) enantioseparation of four β-blocking agents metoprolol, bisoprolol, propranolol and atenolol was performed on amylose tris-(3,5-dimethylphenylcarbamate) chiral stationary phase using n-hexane-ethanol-diethylamine (DEA) as the mobile phase and related chiral recognition mechanisms were discussed. Enantiomeric separation of the fourβ-blockers was ...

Recent advances in SPE-chiral-HPLC methods for enantiomeric separation of chiral drugs in biological samples.

In medical practices, the determination of enantiomeric ratio of the chiral drugs is very important for their activities, bioavailabilities and biodegradation. Only homochiral medication is safe for humans. The chiral analysis in biological samples is the first and most important step. The present article describes the technical strategies of the enantiomeric resolution of racemic drugs in biol...
