- Dextrose (referred to as D-glucose in literature) exerts effects on pancreatic beta cells and enterochromaffin-like BON cells[2][3]
|
|---|---|
| 体外研究 (In Vitro) |
- 在胰岛β细胞培养体系中,葡萄糖(Dextrose)异构体(α-D-葡萄糖、β-D-葡萄糖)可保护细胞免受四氧嘧啶诱导的坏死。在10-50 mM浓度下,两种异构体均能减少β细胞死亡,其中β-D-葡萄糖的保护作用稍强;与单独四氧嘧啶组相比,细胞存活率提高20-40% [2]
- 在体外培养的人BON细胞(用作肠嗜铬细胞模型)中,葡萄糖(Dextrose)呈浓度依赖性诱导5-羟色胺(5-HT)释放。在5 mM、10 mM、25 mM浓度下,5-HT释放量分别为基础释放水平的1.5倍、2.3倍、3.1倍;该效应在L-葡萄糖(不可代谢异构体)处理组中未观察到 [3] |
| 体内研究 (In Vivo) |
- 在经四氧嘧啶(β细胞毒素)处理的小鼠中,于四氧嘧啶给药前30分钟给予葡萄糖(Dextrose)异构体(α-D-葡萄糖或β-D-葡萄糖,2 g/kg,腹腔注射),可显著阻止四氧嘧啶诱导的高血糖。处理后24小时,葡萄糖(Dextrose)预处理组的血糖水平比单独四氧嘧啶组低40-50%;组织学检查显示,其胰岛中坏死的β细胞数量更少 [2]
|
| 细胞实验 |
- 胰岛β细胞实验流程:从小鼠体内分离胰岛,纯化β细胞后在含5.6 mM葡萄糖的培养基中培养。将细胞分为对照组、四氧嘧啶(1 mM)处理组、葡萄糖(Dextrose)异构体(10-50 mM)+四氧嘧啶共处理组。培养24小时后,通过台盼蓝排斥实验检测细胞活力,采用苏木精-伊红染色观察β细胞坏死情况 [2]
- 人BON细胞实验流程:将BON细胞在含10%胎牛血清的培养基中培养。细胞饥饿处理2小时后,用葡萄糖(Dextrose)(5-25 mM)或L-葡萄糖(25 mM)处理30分钟。收集培养上清液,通过高效液相色谱(HPLC)结合电化学检测法测定5-HT浓度 [3] |
| 动物实验 |
- Male mice were randomly divided into three groups: control group, alloxan group, and Dextrose pretreatment group. Mice in the Dextrose group received α-D-glucose or β-D-glucose (dissolved in normal saline, 2 g/kg) via intraperitoneal injection. Thirty minutes later, mice in the alloxan group and Dextrose group were injected with alloxan (75 mg/kg, intraperitoneal injection). Blood glucose levels were measured at 0 hour, 12 hours, and 24 hours after alloxan injection. At the end of the experiment, mice were sacrificed, and pancreatic tissues were collected for histological analysis [2]

Aldehydo-D-glucose is the open chain form of D-glucose. It is a D-glucose and an aldehydo-glucose. It is an enantiomer of an aldehydo-L-glucose.
(2R,3S,4R,5R)-2,3,4,5,6-pentahydroxyhexanal has been reported in Maclura pomifera, Rehmannia glutinosa, and other organisms with data available. (2R,3S,4R,5R)-2,3,4,5,6-pentahydroxyhexanal has been reported in Maclura pomifera, Rehmannia glutinosa, and other organisms with data available. A primary source of energy for living organisms. It is naturally occurring and is found in fruits and other parts of plants in its free state. It is used therapeutically in fluid and nutrient replacement.

View More ... - Dextrose (D-glucose) is a metabolizable monosaccharide, and its protective effect on pancreatic beta cells may be related to its ability to compete with alloxan for uptake into beta cells (via glucose transporters), thereby reducing alloxan-induced oxidative stress and cell necrosis [2] - The release of 5-HT from BON cells induced by Dextrose suggests that it may regulate enterochromaffin cell function in the gastrointestinal tract, which is involved in the regulation of gastrointestinal motility and secretion [3] - Dextrose can be quantitatively and qualitatively analyzed using a Cu foam electrode; this method has high specificity for D-glucose (no cross-reaction with D-galactose or D-lactose) and a detection range of 0.1-10 mM, which is applicable for glucose detection in food samples [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。
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL ddH2O,混匀澄清。
(1) 请确保溶液澄清之后,再加入下一种溶剂 (助溶剂) 。可利用涡旋、超声或水浴加热等方法助溶;
