Method description

By the use of monolayer cultures as an in vitro system, the effects of drugs on CYP3A activity can be evaluated. It relies on the use of a luminogenic CYP3A substrate, namely luciferin-6′-pentafluorobenzylether (luciferin- PFBE). Upon biotransformation by CYP3A, luciferin-PFBE is converted into luciferin, which generates light when combined with a luciferin detection reagent. The normalization of the data relies on the cell number and cell viability and is evaluated by another bioluminescence reaction in which the levels of adenosine- 5′-triphosphate (ATP), the basic energy source of living cells, is measured.
