title: Biopartitioning micellar chromatography separation methods: modelling quantitative retention-activity relationships of cephalosporins.
abstract: In this article, recent applications of chromatographic systems, particularly biopartitioning micellar chromatography (BMC) systems based on amphiphilic structures, have been reported. The aim is to take a look at the capability of quantitative retention-activity relationship (QRAR) models with BMC to describe and/or estimate the bioactivity of cephalosporins. Better qualification of BMC systems was obtained according to the octanol-water partition coefficient (log P); the bioactivity parameters (Lag-T, T(1/2beta), F%, T(1/a), P%, AUC and C(max)) were correlated with the retention factors of cephalosporins processed by Alltech-chromstation software, and the classical data were compared with the predictive values based on QRAR models. The results indicate that using only one descriptor (the retention factor, k) to explain the pharmacokinetic and pharmacodynamic properties of cephalosporins is adequate, and this in vitro approach is an advanced tool for pharmacodynamics research.
