Background | Icariin is a flavonoid glycoside that inhibits PDE5 and PDE4 activity. It is also a PPARα activator. |
Biological Activity | Icariin 是一种黄酮醇苷。 Icariin 抑制 PDE5 和 PDE4 活性, IC50 分别为 432 nM 和 73.50 μM。Icariin 也是一种 PPARα 激活剂[1-4]。 |
IC50 | PDE5:432nM (IC50) PDE4:73.5μM (IC50) [1-4] |
In Vitro | 淫羊藿苷是cGMP特异性PDE5抑制剂。通过用3H-cGMP / 3H-cAMP的两步放射性同位素程序研究了淫羊藿苷对PDE5和PDE4活性的抑制作用。淫羊藿苷对PDE5(IC50的PDE4 / PDE5)的选择性效力为167.67倍[1]。在本研究中测量细胞活力以评估淫羊藿苷是否保护内皮HUVEC免受氧化的低密度脂蛋白(ox-LDL)诱导的损伤。与对照组相比,细胞暴露于ox-LDL 24小时显着降低细胞活力(P <0.05)。然而,淫羊藿苷可以浓度依赖性地抑制ox-LDL诱导的细胞损伤,并且与ox-LDL模拟组相比具有显着差异(P <0.05)[3]。 |
In Vivo | 淫羊藿苷是PPARα激活剂,诱导Cyp4a10和Cyp4a14,并调节脂质代谢酶和蛋白质的mRNA水平,包括脂肪酸结合蛋白,线粒体和过氧化物酶体中的脂肪酸氧化。淫羊藿苷可有效治疗高脂血症。为了解淫羊藿苷对脂质代谢的影响,研究了淫羊藿苷对PPARα及其靶基因的影响。小鼠用淫羊藿苷口服治疗,剂量为0,100,200和400mg / kg,或氯贝特(500mg / kg),持续5天。分离肝脏总RNA,检测PPARα和脂质代谢基因的表达。淫羊藿苷诱导PPARα及其标记基因Cyp4a10和Cyp4a14 2-4倍,氯贝特诱导4-8倍。脂肪酸(FA)结合和共激活蛋白Fabp1,Fabp4和Acsl1增加2倍。线粒体FAβ-氧化酶(Cpt1a,Acat1,Acad1和Hmgcs2)的mRNA增加2-3倍。淫羊藿苷和氯贝特也增加了近端β-氧化酶(Acox1,Ech1和Ehhadh)的mRNA。淫羊藿苷调节元件结合因子-1(Srebf1)和FA合成酶(Fasn)的mRNA表达未被淫羊藿苷改变。脂质溶解基因Lipe和Pnpla2由淫羊藿苷和氯贝特[2]增加。成年大鼠用淫羊藿苷口服治疗,剂量为0(对照),50,100或200mg / kg体重,连续35天。结果表明,淫羊藿苷对睾丸或附睾的体重或器官系数几乎没有影响。然而,100 mg / kg淫羊藿苷显着增加附睾精子数量。此外,50和100 mg / kg淫羊藿苷显着增加睾酮水平。此外,100mg / kg淫羊藿苷治疗还影响支持细胞中的卵泡刺激素受体(FSHR)和密蛋白-11 mRNA表达。在睾丸中测量超氧化物歧化酶(SOD)活性和丙二醛(MDA)水平; 50和100 mg / kg淫羊藿苷治疗可提高抗氧化能力,而200 mg / kg淫羊藿苷治疗可上调氧化应激[4]。 |
Cell Experiment | 将对数生长期的人脐静脉内皮细胞(HUVEC)以1×10 4个细胞/孔的密度接种到96孔板中,然后在37℃,5%CO 2下孵育24小时。在用指定浓度的淫羊藿苷(0,10,20,40μM)预处理24小时后,将细胞与或不与ox-LDL(100μg/ mL)一起温育24小时。在孔中抽吸液体后,加入MTT溶液以产生0.5mg / mL的终浓度,并在37℃,5%CO 2下继续孵育4小时。轻轻除去MTT溶液,向每个孔中加入150μLDMSO,孵育15分钟。每个样品的吸光度在酶标仪上在490nm处测量为细胞活力[3]。 |
Animal Experiment | 小鼠[2]成年8周龄雄性C57BL / 6小鼠在温度和湿度受控的设施中适应1周,具有标准的12小时光照时间表。小鼠可以免费获得SPF级啮齿动物食物和纯净的饮用水。用淫羊藿苷(100,200和400mg / kg)处理小鼠5天。氯贝特(CLO,500mg / kg,口服5天)用作阳性对照,对于阴性对照,给予小鼠2%CMC(10mL / kg)。最后一次给药后24小时,收集肝脏用于分析。大鼠[4]将40只体重200-290g(12-16周龄)的成年雄性SD大鼠根据其体重随机分组(每组n = 10)。大鼠每天以0(对照),50,100或200mg / kg每天接受淫羊藿苷的胃内给药,连续35天。每周称重动物,并相应地调整处理。在淫羊藿苷治疗期结束时,所有大鼠都被处死; 随后收集血样用于进一步分析睾酮水平。 |
