Enantiospecific analysis by capillary electrophoresis: Applications in drug metabolism and pharmacokinetics

Abstract: Enantiospecific analysis has an important role in drug metabolism and pharmacokinetic investigations and its now no longer acceptable to determine total drug, or metabolite, concentrations following the administration of a racemate. Inspite of the fact that capillary electrophoresis (CE) has become an essential technique in pharmaceutical and enantiospecific analysis, the chromatographic methodologies remain the most commonly used approach for the determination of the enantiomeric composition of drugs in biolo… Show more

“…This work required the development of stereoselective assays for a variety of applications [25][26][27][28][29][30][31]. Enantioselective CE assays were found to be attractive approaches for the assessment of the stereoselectivity of drug metabolism [32][33][34]. Our previously reported assay for ketamine and its metabolites which is based on the use of multiple isomersulfated-CD as chiral selector, has been successfully used for the monitoring of the enantiomers of ketamine, norketamine and 5,6-dehydronorketamine in equine plasma [26,31], urine [26] and in vitro preparations [30].…”

“…Currently, there is a great interest in the separation of enantiomers, which are biologically important compounds. It is important to study the relation between chirality and a drug therapeutical efficacy, drug metabolism and pharmacokinetic investigation [67][68][69]. Hadwiger et al were the first to employ CE-EC to analyze enatiomers of isoproterenol in microdialysates by adding a chiral agent, to the running buffers [70].…”

“…Por outro lado, tentativas na utilização da (-)-(R)-fluoxetina como enantiômero puro no tratamento da depressão, por causa de sua cinética mais simples e menor efeito inibidor da enzima CYP2D6, não foram bem sucedidas em razão dos efeitos colaterais (ritmo cardíaco anormal) observados em estudos clínicos, que não são observados com o uso do racemato 1 . Todos esses dados apresentados acima foram um forte estímu-lo para o desenvolvimento de métodos analíticos enantiosseletivos [22][23][24][25] . O desenvolvimento de métodos analíticos adequados para determinar precisamente as concentrações dos enantiômeros de um fármaco, seja em fluidos biológicos ou em preparações farmacêu-ticas é, obviamente, um pré-requisito essencial para estabelecer os parâmetros farmacocinéticos e controlar a qualidade, respectivamente.…”

As principais técnicas analíticas capazes de fornecer essas informações são baseadas na ciência da separação 25 . A cromatografia líquida de alta eficiência (HPLC, "Highperformance Liquid Chromatography") é a técnica mais utilizada para a separação de enantiômeros.…”
