[0002] Rosuvastatin calcium is an HMG-CoA reductase inhibitor, which can be used to treat atherosclerosis, hyperlipidemia, familial hypercholesterolemia and similar diseases. The molecular formula of rosuvastatin calcium is as follows:
[0003]
[0004] Rosuvastatin calcium is a calcium salt formed by basification of a single enantiomer (3R, 5S) carboxylic acid. The dihydroxyheptenoic acid part of the molecule is the common pharmacophore of statins, and the rest is different from other The presence of a polar methanesulfonyl amino group makes it relatively less lipophilic. The hydrophilicity of rosuvastatin calcium means that its passive diffusion ability is low, so it is diff...
