Biologische Aktivität

Beschreibung Ezetimibe (SCH-58235) ist ein potenter, selektiver Cholesterinabsorptionshemmer, der zur Senkung des Cholesterinspiegels eingesetzt wird.
Targets
NPC1L1
In vitro Ezetimibe (SCH-58235) produces a significant reduction in total cholesterol, LDL cholesterol, and triglycerides as well as a small but significant increase in HDL cholesterol. This compound reduces cholesterol transport by 31% in Caco-2 cells, but not retinol transport. It results in a significant decrease in mRNA expression for the surface receptors SR-BI, Niemann-Pick type C1 Like 1 protein (NPC1L1), and ATP-binding cassette transporter, subfamily A (ABCA1) and for the nuclear receptors retinoid acid receptor (RAR)gamma, sterol-regulatory element binding proteins (SREBP)-1 and -2, and liver X receptor (LXR)beta as assessed by real-time PCR analysis in Caco-2 cells.
In vivo Ezetimibe (SCH-58235) reduces plasma cholesterol levels from 964 to 374 mg/dL, from 726 to 231 mg/dL, and from 516 to 178 mg/dL in the western, low-fat, and cholesterol-free diet mice, respectively. It reduces aortic atherosclerotic lesion surface area from 20.2% to 4.1% in the western diet group and from 24.1% to 7.0% in the low-fat cholesterol diet mice. This compound reduces carotid artery atherosclerotic lesion cross-sectional area by 97% in the western and low-fat cholesterol groups and by 91% in the cholesterol-free mice. It inhibits cholesterol absorption, reduces plasma cholesterol, increases high density lipoprotein levels, and inhibits the progression of atherosclerosis under western, low-fat, and cholesterol-free dietary conditions in apoE-/- mice. Ezetimibe potently inhibits the transport of cholesterol across the intestinal wall, thereby reducing plasma cholesterol in preclinical animal models of hypercholesterolemia. It eliminates exocrine pancreatic function from the intestine while maintaining bile flow, as established in the rat. The compound reduces plasma cholesterol and hepatic cholesterol accumulation in cholesterol-fed hamsters with an ED(50) of 0.04 mg /kg.

Caco-2 cells grown in transwell inserts were transfected with scrambled siRNA, or siRNA specific for CCK1R, CCK2R, or both CCK1 and CCK2R and then incubated with 0.002 uCi of [<sup>3</sup>H]cholesterol micelles in the apical compartment and with culture medium alone (Control) or 10 nm [Thr28,Nle31]CCK with or without 50 uM ezetimibe (EZ) in the basolateral compartment. Absorbed [<sup>3</sup>H]cholesterol was determined by radioactivity counting of the basolateral medium. Values represent the mean ± S.E. (error bars) of 4-5 independent experiments. *, p < 0.05 versus control; †, p < 0.05 versus cells treated with CCK alone; ‡, p < 0.05 versus cells transfected with scrambled siRNA alone; $, p < 0.05 versus cells treated with scrambled siRNA and CCK.

<p>Effect of bile duct ligation, proglumide or ezetimibe on cholecystokinin-elevated plasma cholesterol. LDLR-/- mice were subjected to bile duct ligation (BDL), or intravenous injection of 150 mg/kg proglumide, or were gavage-fed with 5 mg/kg ezetimibe. At 30 min after bile duct ligation, or the administration of proglumide or ezetimibe, mice were intravenously injected with 50 ng/kg of cholecystokinin (CCK) or an equal volume of PBS (control) Blood samples were collected at 2 h after CCK or vehicle injection. Plasma cholesterol was measured with a colorimetric assay. Differences among samples obtained from mice before (control) and after treatment with CCK alone, CCK+BDL, CCK+proglumide or CCK+ezetimibe were analyzed by two-way ANOVA followed by Tukey post-hoc tests. Values represent the mean ± SEM of six independent experiments. *P＜0.05 compared to control, and †P＜0.05 compared to CCK treatment alone.</p>
