| 体内研究 (In Vivo) |
在饲喂高碳水化合物(HC,43%碳水化合物)饲料的团头鲂幼鱼中,日粮中添加 1.425 mg/kg 的 benfotiamine 饲喂12周,与单独饲喂 HC 饲料的鱼相比,改善了生长性能(增加了终末体重、增重率、特定生长率)。
日粮中添加 1.425 mg/kg 的 benfotiamine 改善了 HC 饲料诱导的代谢紊乱。它显著提高了血浆胰岛素水平以及组织(肝脏、肌肉、脂肪)糖原和脂质含量,同时显著降低了鱼体内的血浆葡萄糖、糖化血清蛋白(GSP)和晚期糖基化终末产物(AGEs)水平。 Benfotiamine 补充(1.425 mg/kg)提高了鱼肝脏中磷酸化 AMPKα 与总 AMPKα 蛋白的比率以及 PGC-1β 的蛋白表达。 Benfotiamine 补充(1.425 mg/kg)上调了肝脏中与线粒体生物合成和融合相关基因的 mRNA 转录,包括 AMPKα-2、PGC-1β、NRF-1、线粒体转录因子 A (TFAM)、线粒体融合蛋白1 (Mfn-1) 和视神经萎缩蛋白1 (Opa-1)。相反,它下调了与线粒体分裂相关基因的转录,如动力相关蛋白1 (Drp-1)、分裂蛋白1 (Fis-1) 和线粒体分裂因子 (Mff)。 Benfotiamine 补充(1.425 mg/kg)提高了鱼肝脏中线粒体呼吸链复合物 I、II、III、IV 和 V 的活性。 Benfotiamine 补充(1.425 mg/kg)提高了肝脏中线粒体功能相关基因的 mRNA 转录,包括细胞色素 b (CYT-b)、细胞色素 c 氧化酶-2 (COX-2) 和 ATP 合酶-6 (ATP-6)。 在此鱼模型 HC 饲料条件下,改善生长和线粒体功能的最佳日粮剂量为 1.425 mg/kg。更高剂量(2.85 和 5.7 mg/kg)未提供额外益处,且最高剂量甚至损害了生长。[1] |
| 酶活实验 |
在分离的肝脏线粒体中测量了线粒体呼吸链复合物的活性。简要步骤如下:将肝脏样本在含有 KH2PO4、蔗糖和 EDTA 的冰冷提取介质中匀浆。匀浆液低速离心,保留上清液。通过进一步离心获得线粒体部分。将沉淀物(线粒体沉淀)洗涤、重悬并保存。测定线粒体蛋白浓度。使用已建立的分光光度法或其他生化方法测量复合物 I、II、III、IV 和 V 的活性。复合物 I-III 活性根据参考文献方法测量。复合物 IV 和 V 活性使用另一参考文献方法进行分析。活性以纳摩尔/分钟/毫克蛋白表示。[1]

| 动物实验 |
Three hundred sixty juvenile blunt snout bream (average initial weight: 45.25 ± 0.34 g) were randomly distributed into 24 tanks (15 fish per tank). The fish were fed one of six experimental diets for 12 weeks. The diets included: a control diet (30% carbohydrate, C), a high-carbohydrate diet (43% carbohydrate, HC), and the HC diet supplemented with four different levels of benfotiamine: 0.7125 (HCB1), 1.425 (HCB2), 2.85 (HCB3), and 5.7 (HCB4) mg per kg of diet. The benfotiamine was mixed into the diet during formulation. Fish were fed to visual satiation three times daily (07:00, 12:00, and 17:00). Water temperature was maintained at 27.4 ± 0.6°C, with a photoperiod of 12h light:12h dark, and dissolved oxygen above 5.0 mg/L. After the 12-week feeding period, fish were fasted for 24 hours, anesthetized, and blood and tissues (liver, muscle, adipose) were collected for analysis. [1]

| 毒性/毒理 (Toxicokinetics/TK) |
Dietary benfotiamine supplementation at 5.7 mg/kg (the highest dose tested) significantly decreased the final weight, weight gain rate, and specific growth rate of the fish compared to the optimal dose group, indicating a potential growth-retarding effect at this high dose under the experimental conditions. No mortality was observed in any group during the 12-week trial. The study did not provide specific toxicity data such as LD50, organ histopathology, or plasma biochemical markers of organ damage.

| 其他信息 |
Benfotiamine is a thioester that is a synthetic analogue of thiamine obtained by acylative cleavage of the thiazole ring and O-phospohorylation. It has a role as an immunological adjuvant, a nutraceutical, an antioxidant, a provitamin B1 and a protective agent. It is an aminopyrimidine, a member of formamides, an organic phosphate and a thioester. It is functionally related to a thiamine(1+).
Benfotiamine has been investigated for the treatment and prevention of Diabetic Nephropathy and Diabetes Mellitus, Type 2. See also: Benfotiamine (annotation moved to). Benfotiamine is used as a food supplement for the treatment of diabetic complications. It can improve glucose homeostasis by blocking three major pathways associated with hyperglycemic damage: the hexosamine pathway, the advanced glycation end products (AGEs) formation pathway, and the diacylglycerol (DAG)-protein kinase C pathway. Benfotiamine can enhance the activity of dehydrogenase enzyme complexes by increasing intracellular thiamine diphosphate (TPP) levels, thereby increasing glucose oxidation in mitochondria. Benfotiamine can alleviate stress caused by overproduction of superoxide anion in the mitochondrial electron transport chain. In this fish study, benfotiamine improved mitochondrial biogenesis and function in the liver by activating the AMPK/PGC-1β/NRF-1 axis, upregulating mitochondrial fusion genes, enhancing mitochondrial respiratory chain complex activities, and suppressing mitochondrial fission.

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。
