로수바스타틴 C화학적 특성, 용도, 생산
개요
Rosuvastatin is the most recent FDA-approved statin (doses 5–40 mg) for the treatment of dyslipidemia. Rosuvastatin, which has a structure similar to other synthetic statins, has a long halflife (20–24 hours) similar to atorvastatin and hydrophilicity comparable to pravastatin. Consequently, rosuvastatin is minimally metabolized and has no significant cytochrome P450 drug interactions. The efficacy of rosuvastatin is superior to that of other statins. Compared to atorvastatin, rosuvastatin provides approximately an 8% additional lowering of LDL-C on an equivalent dose level. This provides modestly more efficacy than a doubling of the dose of atorvastatin. Rosuvastatin also increases HDL-C slightly more than atorvastatin, especially at the highest doses.
용도
Rosuvastatin Calcium is a competitive inhibitor of HMG-CoA reductase with IC50 of 11 nM.
정의
ChEBI: Rosuvastatin is a dihydroxy monocarboxylic acid that is (6E)-7-{4-(4-fluorophenyl)-2-[methyl(methylsulfonyl)amino]-6-(propan-2-yl)pyrimidin-5-yl} hept-6-enoic acid carrying two hydroxy substituents at positions 3 and 5 (the 3R,5S-diastereomer). It has a role as an antilipemic drug, an anti-inflammatory agent, a CETP inhibitor, a cardioprotective agent, a xenobiotic and an environmental contaminant. It is a member of pyrimidines, a sulfonamide, a dihydroxy monocarboxylic acid, a statin (synthetic) and a member of monofluorobenzenes. It derives from a hept-6-enoic acid. It is a conjugate acid of a rosuvastatin(1-).
제조 방법
Rosuvastatin synthesis: Reduction to the 5-hydroxymethyl derivative proceeds smoothly with diisobutylaluminum hydride (DIBALH) in toluene at -10 °C. The hydroxymethyl group is then converted to the bromo derivative, which upon reaction with triphenylphosphine affords the Wittig reagent. The latter is treated with tert-butyl 2-[(4R,6S)-6-formyl-2,2-dimethyl-1,3-dioxan-4-yl]acetate and provides the protected rosuvastatin ester. Removal of the dioxane protecting group by HCl, ester hydrolysis with NaOH and precipitation with CaCl2 gives rosuvastatin.

일반 설명
Rosuvastatin, 7-[4-(4-fluorophenyl)-6-(1-methylethyl)-2-(methyl-methylsulfonyl-amino)-pyrimidin-5-yl]-3,5-dihydroxy-hept-6-enoic acid (Crestor), is oneof the more recently introduced statins in the United States.As with all statins, there is a concern of rhabdomyolysis andas such, the FDA has mandated that a warning about thisside effect, as well as a kidney toxicity warning, be added tothe product label (http://www.fda.gov/CDER/Drug/advisory/crestor_3_2005.htm). This should not come as a surprisebecause of the relationship in the chemical architectureto cerivastatin, which was withdrawn from the market as aresult of its adverse side effects.
