Ginsenoside Rh3 是一种从人参 C. A. Mey 中提取的天然产品。Ginsenoside Rh3 具有抗真菌和抗氧化活性,处理人视网膜细胞可诱导 Nrf2 。
产品描述 | Ginsenoside Rh3 is a natural product extracted from Ginseng C. A. Mey.Ginsenoside Rh3 has antifungal and antioxidant activities and induces Nrf2 activation in human retinal cells. |
体外活性 | Ginsenoside Rh3(0.01、0.1、1 和 10 μM)在所有浓度下均未显示出细胞毒性效应。[2] 在视网膜细胞中,Ginsenoside Rh3处理可诱导Nrf2激活。Ginsenoside Rh3对视网膜色素上皮细胞(RPEs)中Nrf2信号传导的潜在活性进行了测试。qRT-PCR实验结果显示,Ginsenoside Rh3处理以剂量依赖性方式增加了Nrf2调控基因,包括HO1、NQO1和GCLC的mRNA转录和表达。因此,这些Nrf2依赖性基因(HO1、NQO1和GCLC)的蛋白表达在Ginsenoside Rh3(3-10 μM)处理的RPEs中也显著增加。值得注意的是,尽管Ginsenoside Rh3处理后Nrf2 mRNA水平未改变,但其蛋白水平却因Rh3显著增加[1]。使用EZ-Cytox方法评估了ginsenoside-Rh3对SP 1角蛋白细胞活性的影响。[2] |
体内活性 | Ginsenoside Rh3(5 mg/kg;眼内注射;治疗前30分钟)显著减轻光照引起的a波和b波振幅下降。电视网膜图(ERG)显示,光照后a波降至对照水平的46.03±1.62%,而经Ginsenoside Rh3处理后恢复至71.84±7.51%。b波在光照作用下降至对照水平的40.19±3.34%,Rh3眼内注射后恢复至对照水平的80.01±2.37%。[1] |
细胞实验 | SP-1 keratinocytes are seeded in 96 well plates (2×10^4 cells/well). After 24 h, the media is replaced with media containing various concentrations of (A) SKRG, or (B) Ginsenoside Rh3 (0.01, 0.1, 1 and 10 μM). Control cells are treated with DMSO at a final concentration of 0.1%. After 24 h, the media containing the compounds or DMSO is replaced with media containing 10% EZ-Cytox. The cells are then incubated at 37°C for 1 h, and the absorbance is measured using a microplate reader at a wavelength of 450 nm. All assays are performed in triplicate [2]. |
动物实验 | The BALB/c mice (male, 5-6 week old, 17-18 g weight) are used. The pupillary dilation is performed before exposure to 5000 lx of white fluorescent light. Thirty min before light exposure, Ginsenoside Rh3 (at 5 mg/kg body weight) is injected intravitreally to the right eye. ERG recording after light exposure is also reported early. The b-wave amplitude is measured from the trough of the a-wave to the peak of the b-wave, and the amplitude of the a-wave is measured from the initial baseline [1]. |

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
