(±)-α-Tocopherol acetate (600 mg/kg, 1200 mg/kg, 1800 mg/kg; 15, 30, and 45 days) after 30 days of in vivo fish administration method increases nonspecific immunity in sea bream. Consumption (1200 mg/kg) [1].
In vivo, (±)-α-Tocopherol acetate inhibits heat-stress-induced decreases in blastocyst number in pregnant mice when administered at a dose of 1 g/kg. It also inhibits heat-stress-induced decreases in glutathione levels in isolated mouse zygotes in a model of hyperthermia-induced pre-implantation embryonic death. The compound has oral activity and is used in studies of fish susceptibility to infectious diseases. Its antioxidant and cytoprotective effects make it a valuable compound for research on oxidative stress and reproductive biology.

Animal Protocol
Animal/Disease Models: Gilthead seabream (Sparus aurata L.) [1]
Doses: 600 mg/kg, 1200 mg/kg, 1800 mg/kg
Route of Administration: oral; 600 mg/kg, 1200 mg/kg, 1800 mg/kg kg; 15-day, 30-day and 45-day
Experimental Results: positively correlated with serum α-tocopherol levels, and the increase is related to dose and time of use. They did not show an enhancement in any immune parameter, while the specific growth rate of fish fed the diet supplemented with 1200 mg/kg was slightly higher (but not statistically significant) than that of fish fed the other diets. After 30 and 45 days, dietary intake of 1200 mg/kg enhanced serum hemolytic activity and phagocytosis of head kidney leukocytes, but leukocyte migration and respiratory burst activity were not affected. Does not cause immune stimulation at 1800 mg/kg.
In vivo animal experiments with (±)-α-Tocopherol acetate have been conducted in pregnant mice to study its effects on heat-stress-induced embryonic death. The compound was administered orally at a dose of 1 g/kg. The number of blastocysts and glutathione levels in isolated mouse zygotes were measured as markers of embryonic development and oxidative stress. The compound's protective effects against heat stress were assessed. The compound has also been used in studies of fish susceptibility to infectious diseases.
ADME/Pharmacokinetics
(±)-α-Tocopherol acetate has a molecular weight of 472.75 g/mol and the formula C31H52O3. The compound is soluble in DMSO at 100 mg/mL.

Additional Infomation
DL-α-Tocopherol acetate is a tocopherol. It has been reported that DL-α-tocopherol acetate is found in catechu (Senegalia catechu), and relevant data exists. Vitamin E acetate is an acetate of the fat-soluble vitamin E, possessing potent antioxidant properties. Vitamin E is considered essential for stabilizing biological membranes, especially those rich in polyunsaturated fatty acids. It is a collective term for tocopherols and tocotrienols (collectively known as tocopherols). Vitamin E is a potent superoxide radical scavenger, capable of non-competitively inhibiting cyclooxygenase activity in various tissues, thereby reducing prostaglandin production. Vitamin E can also inhibit angiogenesis and tumor dormancy by inhibiting vascular endothelial growth factor (VEGF) gene transcription. (NCI04) It is a natural tocopherol and one of the most effective antioxidants. α-Tocopherol possesses antioxidant activity due to the phenolic hydroxyl group on its 2H-1-benzopyran-6-ol core. Its 6-chromoyl alcohol core has four methyl groups. Natural d-α-tocopherol is more active than its synthetic racemic mixture of dl-α-tocopherol.
