Background

Atorvastatin Calcium is a potent inhibitor of HMG-CoA reductase with IC50 value of 150 nM[1].
HMG-CoA reductase is the key enzyme of the mevalonate pathway which produces cholesterol. HMG-CoA is the rate-limiting enzyme and is important for lowering the blood cholesterol levels. HMG-CoA reductase is located in the endoplasmic reticulum and contains eight transmembrane domains. The inhibitors of HMG-CoA reductase can induce the LDL (low density lipoprotein) receptors expression in the liver. It leads to increase the catabolism levels of plasma LDL and lower the concentration of plasma cholesterol which is an important determinant of atherosclerosis. HMG-CoA reductase plays an important role in cholesterol synthesis. HMG-CoA is the ony target for cholesterol-lowering drugs. HMG-CoA reductase is also an important enzyme for development. The activity of HMG-CoA reductase is related to germ cell migration defects. Inhibition of its activity can leadto intracerebral hemorrhage[1].
Atorvastatin is an HMG-CoA reductase inhibitor with IC50 value of 154 nM. It is effective in treating certain dyslipidemias and hypercholesterolemia[1]. Atorvastatin treatment at 40 mg decreases total cholesterol of 40% after 40 days.[1] It also be used to treat coronary or stroke patients with normal cholesterol levels.[2] Atorvastatin also decreases low density lipoprotein apheresis in patients by inducing LDL-receptors expression.
It is metabolized to several metabolites which are important for the effect of the therapeutic actions by CYP3A4 (cytochrome P450 3A4).[3]

运输条件试用装:蓝冰运输。 其他可选规格:常温运输或根据您的要求用蓝冰运输。
一般建议为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。

试验操作

细胞实验 [1]:

细胞系

单核细胞和VSMC

制备方法

在DMSO中的溶解度大于57.8 mg/mL。若配制更高浓度的溶液,一般步骤如下:请将试管置于37 °C加热10分钟和/或将其置于超声波浴中震荡一段时间。原液于-20 °C可放置数月。

反应条件

0.1或1 μM

实验结果

在单核细胞和VSMC中,Atorvastatin Calcium (0.1 μM) 显著抑制由Ang II和TNF-α诱导的NF-κB活化。此外,Atorvastatin Calcium (1 μM) 也下调Ang II和TNF-α诱导的MCP-1和IP-10表达。

动物实验 [2]:

动物模型

后肢缺血小鼠

给药剂量

2或8 mg/kg/day;口服给药;持续4周

实验结果

在后肢缺血小鼠中,Atorvastatin Calcium 在8 mg/kg的剂量下显著恢复血流量。此外,8 mg/kg Atorvastatin Calcium治疗组的缺血/正常灌注比例也有所增加。缺血肌肉组织分析结果表明,Atorvastatin Calcium显著增加毛细血管数量。同时,Atorvastatin Calcium上调上述组织中的CXCR4表达。

注意事项

请于室内测试所有化合物的溶解度。虽然化合物的实际溶解度可能与其理论值略有不同,但仍处于实验系统误差的允许范围内。
