描述 | Rosuvastatin is a hydroxymethylglutaryl coenzyme A reductase inhibitor with an IC50 value of 11nM in vitro.[4] It blocked human ether-a-go-go related gene (hERG) current in HEK293 cells with an IC50 value of 195nM. In isolated guinea pig hearts, rosuvastatin at a concentration of 195nM prolonged the monophasic action potential duration at 90% repolarization by 11ms.[3] Rosuvastatin also inhibited cholesterol biosynthesis in isolated rat hepatocytes with an IC50 value of 0.16nmol/L. In mice with streptozocin-induced diabetes mellitus, rosuvastatin treatment at a dosage of 20 mg/kg/day for 2 weeks significantly reduced the level of very low-density lipoproteins.[5] | ||
作用机制 | Rosuvastatin is a methanesulfonamide derivative that acts as an inhibitor of hydroxymethylglutaryl coenzyme A reductase. It also shows structural similarities with several potassium current blockers and has been reported to blocks hERG current and prolongs cardiac repolarization.[3] |
