| 靶点 |
- Fosfructose trisodium is an endogenous metabolite that acts as an allosteric activator of several enzymes in glycolysis, including:
- Phosphofructokinase-1 (PFK-1): critical rate-limiting enzyme in glycolysis [1] - Pyruvate kinase: converts phosphoenolpyruvate to pyruvate [1] - NAD⁺-dependent L-(+)-lactate dehydrogenase: involved in anaerobic energy production [1] - It also acts as an inhibitor of acetate kinase and serves as a substrate for fructose-1,6-bisphosphate aldolase and fructose-1,6-bisphosphatase [1] |

| 体外研究 (In Vitro) |
- 在细胞实验中,果糖二磷酸三钠 (500 μg/ml)显著增加组织FDP水平(0.22 ± 0.01 mg/g),与对照组(0.14 ± 0.004 mg/g)相比差异显著(p=0.0006) [1]
- 它刺激无氧糖酵解,在缺血条件下增加ATP生成 [1] - 作为变构调节剂,增强细胞对葡萄糖的利用和能量代谢 [1] |
| 体内研究 (In Vivo) |
- 在角叉菜胶诱导的大鼠足肿胀模型中,果糖二磷酸三钠通过增强对缺血组织的能量供应显示抗炎作用,减少水肿形成 [1]
- 在镰状细胞贫血模型中,通过增加细胞内ATP水平改善红细胞柔韧性,减少血管闭塞危象 [1] - 在心血管缺血模型中,通过在缺氧期间维持ATP水平和增强缺血后恢复来保护心脏功能 [1] |
| 药代性质 (ADME/PK) |
- Following intravenous administration (250 mg/kg) to healthy volunteers, Fosfructose trisodium reaches a plasma concentration of 770 mg/L within 5 minutes, with a half-life of 10-15 minutes [1]
- It rapidly distributes to extravascular tissues and is hydrolyzed to inorganic phosphate and fructose, which are then metabolized or excreted [1] - In rats, FDP levels increase simultaneously in blood and brain without lag, but return to baseline in liver, kidney, muscle, and fat by 12 hours while remaining elevated in blood and brain [1] - It has low oral bioavailability due to hydrolysis in the gastrointestinal tract and first-pass metabolism [1] |
| 毒性/毒理 (Toxicokinetics/TK) |
- Acute toxicity in mice and rabbits: lethal dose of 5.0 g/kg and 5.8 g/kg, respectively, when infused at rates of 0.4-0.6 g/kg/min [1]
- Toxicity appears related to large amounts of inorganic phosphate entering circulation after hydrolysis of high doses [1] - Clinical adverse effects include flushing, palpitations, and tingling in hands and feet when infusion rate exceeds 10 ml/min [1] - Rare reports of allergic reactions and anaphylactic shock exist [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:
