Title in Portuguese
Separação, obtenção e utilização de enantômeros puros no controle estereoespecífico de qualidade de medicamentos contendo bisoprolol
Keywords in Portuguese
Bisoprolol
Cromatografia líquida de alta eficiência
Enantiômeros
Separação quiral
Abstract in Portuguese
A diferença na atividade terapêutica, farmacocinética e / ou farmacodinâmica entre os enantiômeros de fármacos quirais impulsionou a necessidade de estudar e desenvolver métodos para determinação exata e precisa da pureza enantiomérica dos produtos farmacêuticos. Inicialmente, os enantiômeros foram separados em escala analítica. As condições analíticas foram adaptadas para a escala semi-preparativa para a obtenção enantiômeros puros. Os enantiômeros do bisoprolol foram separados através de Cromatografia Líquida de Alta Eficiência. Foi adotado o sistema direto de separação, fase normal, utilizando coluna Chiralcel OD (250 x 4,6 mm id). A fase móvel foi composta por hexano: etanol: dietilamina (80:20:0.2, v / v / v), vazão de 1mL/min e detecção em UV a 273 nm. A separação dos enantiômeros (R)-bisoprolol e (S)-bisoprolol foi obtida com sucesso em escala analítica e semi-preparativa. Considerando as características de uma separação quiral, podemos concluir que os resultados são eficazes, por ser uma separação rápida e seletiva.

Abstract in English
The difference in therapeutic activity, pharmacokinetics, and / or pharmacodynamics between enantiomers of chiral drugs has raised the need to study and develop methods for accurate and precise determination of enantiomeric purity of pharmaceutical products. Initially, the enantiomers were separation in analytical scale. The analytical conditions were scaled up to semi-preparative level to obtain pure enantiomers. The enantiomers of bisoprolol were separated with high-performance liquid chromatography. Direct separation system was adopted in normal phase mode using Chiralcel OD column (250 x 4.6 mm id). The mobile phase was composed of hexane:ethanol:diethylamine (80:20:0.2, v/v/v), flow rate of 1mL/min and UV detection was made at 273 nm. The separation of enantiomers, (R)-bisoprolol and (S)-bisoprolol was successfully obtained in analytical and semi-preparative scale. Considering the characteristics of a chiral separation, we can conclude that the results are effective, because it is a fast and selective separation.
