The applicability of computational chemistry in the evaluation and prediction of drug transport properties

摘要

We have investigated the relationship between drug retention in immobilized liposome partitioning chromatography and liposome partitioning and found a strong linear correlation. Separate linear relationships were found depending on the charge of the compound when liposome chromatographic measurements were related to the octanol/water partition coefficients. we have also investigated the importance of the water/octanol partition coefficient in quantitative structure-property relationships related to drug transport properties. The studies show that the inclusion of a parameter related to lipophilicity causes only, at best, a marginal increase in internal predictivity and, at worst, a decrease in external predictivity. The studies also show that parameters related to hydrogen bonding, polarizability and size are important properties that need to be included in quantitative models for drug transport processes. We believe that the use of multivariate characterizations of compounds based on non-composite parameters may result in better and more predictive models compared with models based on parameters of a more composite nature when investigating the possibilities to establish quantitative structure-property relationships.
