a-vitamin e

α-Vitamin E (Dexrabeprazole Sodium) is a naturally-occurring form of vitamin E, a fat-soluble vitamin with potent antioxidant properties.

D-alpha-Tocopherol acetate (Vitamin E Acetate) is hydrolyzed to d-alpha-tocopherol (VE) and absorbed in the small intestine.

DL-alpha-Tocopherol (Ephanyl) is a synthetic vitamin E that protects skin fibroblasts from the cytotoxic effects of UV light and has antioxidant properties.

Methyl 3-(2,4-dihydroxyphenyl)propionate is a novel vitamin E derivative that inhibits tyrosinase, which is an antioxidant and inhibits UV-B-induced hyperpigmentation, with potential whitening effects.

γ-Tocotrienol (Plastochromanol) is one of the four types of tocotrienol, a type of vitamin E. Itl is also a radioprotector, antioxidant. It shows antitumor and antihypertensive effects in vivo.

β-Tocopherol, a vitamin E analog with antioxidant activity, inhibits tyrosinase activity and melanin production while suppressing PMA-induced human erythrocyte adhesion.

DL-alpha-Tocopherol (Vitamin E) (Standard) is the standard substance of DL-alpha-Tocopherol (Vitamin E), and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. DL-alpha-Tocopherol (Ephanyl) is a synthetic vitamin E that protects skin fibroblasts from the cytotoxic effects of UV light and has antioxidant properties.

α-Vitamin E (Standard) is the reference standard of α-Vitamin E suitable for quantitative analysis, quality control, and biochemical experimentation, and this naturally occurring vitamin E compound functions as a lipid-soluble antioxidant that protects cellular membranes from oxidative damage and supports studies of redox biology and nutritional biochemistry.

β-Tocopherol (Standard) is a certified reference material of β-Tocopherol intended for quantitative analysis, quality control, and biochemical research, and as a vitamin E analog it exhibits antioxidant activity, suppresses tyrosinase activity and melanogenesis, and protects cells from growth inhibition and protein kinase C activity reduction induced by α-demethyl tocopherol.

Alpha-Tocotrienol is a vitamin E analogue with neuroprotective properties against apoptosis and antioxidant characteristics. This compound can prevent apoptosis, DNA fragmentation, and changes in nuclear morphology, all occurring independently of oxidative stress.

DL-alpha-Tocopherylacetate ((±)-Vitamin E acetate) is an oral tocopherol supplement with antioxidant activity.

2-Oxopomolic acid shows cytotoxic activity, it shows a significant decrease in intracellular melanin content in B16-F10 cells, and in culture media melanin. 2-Oxopomolic acid shows radical-scavenging activities similar to that of the reference antioxidant
