Bioconversion of the antihistaminc drug loratadine by tobacco cell suspension cultures expressing human cytochrome P450 3A4.
In this study we have expanded the metabolic potential of plant cell suspension cultures by introducing active human cytochrome P450 monooxygenase 3A4 into tobacco cells. Exogenously supplied loratadine was metabolized in a 3A4-specific manner, showing the capacity of this system for the generation of metabolites.
