Cerivastatin (5-50 ng/mL; 3 days; MDA-MB-231 cells) treatment induces a dose-dependent decrease in cell proliferation of MDA-MB-231 cells (up to 40% inhibition at 25 ng/mL).
Cerivastatin (25 ng/mL; 18-36 hours; MDA-MB-231 cells) treatment induces an arrest of the cell cycle in G 1/S phase after 36 h treatment. This arrest is not observed for a shorter incubation time (18 h).
Cerivastatin (25 ng/mL; 18 hours; MDA-MB-231 cells) treatment induces a marked increase in the level of p21 ^Waf1/Cip1 .
Cerivastatin (25 ng/mL; 12 hours; MDA-MB-231 cells) treatment increases the p21 transcript in MDA-MB-231 cells.
Cerivastatin (10-25 ng/mL; 18 hours) inhibits invasion of MDA-MB-231 cells through Matrigel.
Cerivastatin (25 ng/mL; 18-36 hours) delocalizes RhoA and Ras from the membrane to the cytosol and induces morphological changes.
Cerivastatin (25 ng/mL; 4-36 hours) induces inactivation of NFκB, in a RhoA inhibition-dependent manner, resulting in a decrease in urokinase and metalloproteinase-9 expression, and concomitantly increases IκB.

Cerivastatin is well absorbed, reaching maximal plasma levels in 1-3 hours following oral dosing. In the circulation, Cerivastatin is highly bound to plasma proteins (99.5%), with an elimination half-life of 2-4 hours. Cerivastatin is metabolized predominantly in the liver to three polar metabolites. Two of these metabolites are active, but to a lesser extent compared to parent drug, and the third metabolite is inactive. Plasma concentrations of all metabolites are substantially lower than those of the parent drug. Elimination of metabolites is via the urine (20-25%) and feces (66-73%), while essentially no parent compound is excreted.
