Atorvastatin and its inactive enantiomer (3S,5S)-Atorvastatin increases CYP2B and CYP3A mRNA content with equal ability. (3S,5S)-Atorvastatin in 100 μM concentrations induces luciferase activity with an EC 50 of 12.4 μM. Addition of (3S,5S)-Atorvastatin to the 2-formylphenylboronic
acid (FPBA)/l-tryptophanol mixture induces an intensity enhancement of l-tryptophanol florescence.
