(3S,5S)-Atorvastatin is a inactive enantiomer of Atorvastatin. (3S,5S)-Atorvastatin can activate pregnane X receptor (PXR). Atorvastatin is an orally active HMG-CoA reductase inhibitor, has the ability to effectively decrease blood lipids.

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 EC₅₀ 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.
