The invention discloses a method for the treatment of diseases, particularly those diseases characterized by diminished or aberrant cellular function, including AIDS, cancer, and Alzheimer's Disease. The method comprises administering a therapeutically effective amount of rosuvastatin enantiomer compounds in their (3R, 5R), (3S, 5R), or (3S, 5S) configurations, or pharmaceutically acceptable salts thereof. Biologically-active rosuvastatin enantiomer compounds with (3R, 5R), (3S, 5R), and (3S, 5S) stereochemistry are also disclosed.
