Enantiodeterminación de catinonas en orina mediante electroforesis capilar

Abstract

In recent years, the consumption of synthetic derivatives of cathinone, an alkaloid naturally found in the leaves of the khat plant, has increased as they represent a more affordable and accessible alternative to other well-known illicit drugs such as amphetamines. After their consumption, these compounds can be found in the organism either metabolized or in their pure form at low concentrations. Therefore, highly sensitive methods are usually necessary to determine these substances in biological samples such as blood, hair, oral fluids, or, more commonly, urine. Cathinones present a chiral centre, so they can be found in two enantiomeric forms (R and S). Each enantiomer can present different pharmacokinetic and pharmacodynamic behaviour and have different effects on the organism. Consequently, the enantioseparation of synthetic cathinones can be very useful. In these sense, capillary electrophoresis represents an excellent technique for this purpose, since enantioseparation can be achieved simply by adding a chiral selector to the background electrolyte. However, despite of this and other well-known advantages of this analytical technique, one of its main limitations is its poor sensitivity

En los últimos años ha aumentado el consumo de derivados sintéticos de la catinona, un alcaloide que se encuentra de forma natural en las hojas del khat, puesto que representan una alternativa más asequible y accesible respecto a otras drogas ilícitas más conocidas como las anfetaminas. Después de ser consumidos, estos compuestos se pueden encontrar en el organismo ya sea metabolizados o en su forma pura a bajas concentraciones. Por lo tanto, suelen ser necesarios métodos altamente sensibles para determinar estas sustancias en muestras biológicas como sangre, cabello, saliva o, más comúnmente, orina. Las catinonas presentan un centro quiral y, por tanto, se pueden encontrar en dos formas enantioméricas (R y S). Cada enantiómero puede presentar un comportamiento farmacocinético y farmacodinámico diferente y, por consiguiente, tener diferentes efectos en el organismo. En consecuencia, la enantioseparación de las catinonas sintéticas puede ser de gran utilidad. En este sentido, la electroforesis capilar es una técnica muy adecuada para este propósito, puesto que la enantioseparación se puede lograr simplemente agregando un selector quiral al electrolito de separación

Després de ser consumits, aquests compostos es poden trobar en l'organisme ja sigui metabolitzats o en la seva forma pura a baixes concentracions. Per tant, solen ser necessaris mètodes altament sensibles per determinar aquestes substàncies en mostres biològiques com sang, cabell, saliva o, més comunament, orina. Les catinones presenten un centre quiral i, per tant, es poden trobar en dues formes enantiomèriques (R i S). Cada enantiòmer pot presentar un comportament farmacocinètic i farmacodinàmic diferent i, per tant, tenir diferents efectes en l'organisme. En conseqüència, la enantioseparació de les catinones sintètiques pot ser de gran utilitat. En aquest sentit, l'electroforesi capil·lar és una tècnica molt adequada per a aquest propòsit, ja que la enantioseparació es pot aconseguir simplement afegint un selector quiral a l'electròlit de separació.
