A CYP3A4 promoter-reporter gene construct has been used to assess the ability of 16 known (in vivo) and putative (in vitro) inducers to transactivate a CYP3A4 reporter gene in HepG2 cells. With the exception of pravastatin, the remaining 15 compounds transactivated the CYP3A4 reporter gene with differing inductive abilities (I(max):EC(50)) over two orders of magnitude, ranging from 1.1 (phenytoin) to 222.9...
