NCIt definition : A statin with antilipidemic and potential antineoplastic activities. Rosuvastatin
selectively and competitively binds to and inhibits hepatic hydroxymethyl-glutaryl
coenzyme A (HMG-CoA) reductase, the enzyme which catalyzes the conversion of HMG-CoA
to mevalonate, a precursor of cholesterol. This leads to a decrease in hepatic cholesterol
levels and increase in uptake of LDL cholesterol. In addition, rosuvastatin, like
other statins, exhibits pro-apoptotic, growth inhibitory, and pro-differentiation
activities in a variety of tumor cell types; these antineoplastic activities may be
due, in part, to inhibition of the isoprenylation of Ras and Rho GTPases and related
signaling cascades.;
