In H9c2 rat cardiomyocytes injured by H₂O₂ (0.5 mM), Hederagenin 28-O-beta-D-glucopyranosyl ester (10 μM, 20 μM, 40 μM) exerted dose-dependent protective effects.
1. Cell viability: MTT assay showed that H₂O₂ alone reduced cell viability to 45.2% of the control group; pretreatment with 10 μM, 20 μM, and 40 μM Hederagenin 28-O-beta-D-glucopyranosyl ester increased viability to 58.7%, 71.3%, and 82.3% respectively [1] 2. Oxidative stress markers: DCFH-DA staining revealed that 40 μM Hederagenin 28-O-beta-D-glucopyranosyl ester reduced intracellular reactive oxygen species (ROS) levels by 58.6% compared to the H₂O₂ group. It also decreased malondialdehyde (MDA, a lipid peroxidation product) content by 42.1% (40 μM dose) and increased the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) by 35.8% and 41.5% respectively (40 μM dose) [1] |

在0.5 mM H₂O₂诱导损伤的H9c2大鼠心肌细胞中,Hederagenin 28-O-beta-D-glucopyranosyl ester(10 μM、20 μM、40 μM)呈剂量依赖性发挥保护作用。
1. 细胞活力:MTT实验显示,单独H₂O₂处理使细胞活力降至对照组的45.2%;而10 μM、20 μM、40 μM Hederagenin 28-O-beta-D-glucopyranosyl ester 预处理后,细胞活力分别提升至58.7%、71.3%和82.3% [1] 2. 氧化应激指标:DCFH-DA染色显示,40 μM Hederagenin 28-O-beta-D-glucopyranosyl ester 较H₂O₂组降低58.6%的细胞内活性氧(ROS)水平;同时,该剂量下可降低42.1%的丙二醛(MDA,脂质过氧化产物)含量,并分别提升35.8%的超氧化物歧化酶(SOD)活性和41.5%的谷胱甘肽过氧化物酶(GSH-Px)活性 [1] |
| 体内研究 (In Vivo) |
1. 细胞培养与分组:H9c2大鼠心肌细胞用含10%胎牛血清的DMEM培养基,在37°C、5% CO₂条件下培养。细胞分为4组:对照组(无处理)、H₂O₂组(0.5 mM H₂O₂处理4小时)、Hederagenin 28-O-beta-D-glucopyranosyl ester 预处理组(10 μM、20 μM、40 μM药物预处理2小时后,再加入H₂O₂)[1]
2. 细胞活力检测:处理结束后,向细胞中加入5 mg/mL MTT试剂,37°C孵育4小时。吸除上清液,加入DMSO溶解甲瓒结晶,在570 nm波长处测定吸光度,计算细胞活力 [1] 3. 氧化应激检测:ROS检测时,细胞加载10 μM DCFH-DA探针30分钟,洗涤后在荧光显微镜下观察并定量荧光强度;MDA、SOD、GSH-Px检测时,制备细胞匀浆,使用商品化检测试剂盒,按说明书步骤测定其含量或活性 [1] |
| 毒性/毒理 (Toxicokinetics/TK) |
In normal H9c2 cardiomyocytes (untreated with H₂O₂), a concentration of up to 40 μM of Hederagenin 28-O-β-D-glucopyranose ester did not show significant cytotoxicity. MTT assay results showed that 24 hours after drug treatment, cell viability remained above 95% compared with the control group, indicating that there was no significant damage to normal cardiomyocytes [1].

Ivy saponin 28-O-β-D-glucopyranoside is a triterpenoid saponin, which is a carboxylic acid ester formed by the condensation of the carboxyl group of ivy saponin with β-D-glucopyranoside. It has been isolated from walnut (Juglans sinensis). Ivy saponin has plant metabolites and anti-inflammatory activities. It is a triterpenoid saponin, a pentacyclic triterpenoid compound, a monosaccharide derivative, a β-D-glucopyranoside and a carboxylic acid ester. Its function is related to ivy saponin. It is derived from the hydride of oleanane.
It has been reported that ivy saponin 28-O-β-D-glucopyranoside is found in Achyranthes bidentata, Acer rubrum, and other organisms with relevant data. Ivy saponin 28-O-β-D-glucopyranoside is a novel triterpenoid saponin isolated from the leaves of the traditional Chinese medicine plant Ilex chinensis[1]. Ivy saponin 28-O-β-D-glucopyranose The protective effect of H₂O₂-induced cardiomyocyte damage is mainly achieved by inhibiting oxidative stress: it can reduce the generation of reactive oxygen species (ROS) and lipid peroxidation (reduce malondialdehyde (MDA) level), while enhancing the activity of endogenous antioxidant enzymes (superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px)), thereby restoring the redox balance of cells [1]. |

1、根据实验需要选择合适的溶剂配制储备液 (母液):对于大多数产品,InvivoChem推荐用DMSO配置母液 (比如:5、10、20mM或者10、20、50 mg/mL浓度),个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;
2、如果您找不到您想要的溶解度信息,或者很难将产品溶解在溶液中,请联系我们;
3、建议使用下列计算器进行相关计算(摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等);
4、母液配好之后,将其分装到常规用量,并储存在-20°C或-80°C,尽量减少反复冻融循环。
计算结果:
工作液浓度: mg/mL;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL)。如该浓度超过该批次药物DMSO溶解度,请首先与我们联系。
