| Biochem/physiol Actions: | |
| Biochem/physiol Actions: | Tocopherols (TCP) (vitamin E) are a series (α, α, α and α) of chiral organic molecules that vary in their degree of methylation of the phenol moiety of the chromanol ring. Tocopherols are lipid soluble anti-oxidants that protect cell membranes from oxidative damage. α-Tocopherol is the form of tocopherol preferentially absorbed by homo sapiens. Tocopherol polyethylene glycol 1000 succinate (TPGS) may be used to create biodegradable polymers and antioxidant surfactants. TPGS exerts anti-tumor activity in MCF-7 and breast cancer cells by downregulating anti-apoptotic proteins. TPGS finds its application as an emulsifier in the preparation of poly(lactic-co-glycolic acid) (PLGA) particles for DNA labelling, produces particles of uniform size, high encapsulation efficiency, increases hydrophilicity and prevents aggregation of particles. |
| Features and Benefits: | • Can be used in Metabolomics and Biochemical research • High-quality compound suitable for multiple research applications |
| General description: | Tocofersolan, also known as Vitamin E-TPGS, is a nonionic surfactant and a synthetic polyethylene glycol derivative of α-tocopherol, commonly known as vitamin E. This water-soluble amphipathic formulation consists of d-alpha-tocopherol succinate coupled to polyethylene glycol (PEG) 1000 through a succinate linker. Its amphipathic nature enables the formation of micelles, facilitating uptake into enterocytes, even in the absence of bile salts. Upon hydrolysis, fat-soluble d-alpha-tocopherol is released. Tocofersolan significantly improves the absorption of d-alpha-tocopherol compared to free administration. Moreover, Tocofersolan acts as an inhibitor of P-glycoprotein (P-gp or MDR1) substrate-induced ATPase activity in cell-free assays. It has demonstrated efficacy against resistant K562 cells by binding to urokinase-type plasminogen activator, a crucial enzyme for cancer cell migration and invasion. Additionally, Tocofersolan inhibits tyrosine kinase, a key player in cancer cell development, offering potential applications in metabolomics and biochemical research. Its ability to enhance the absorption of water-insoluble agents and other fat-soluble vitamins positions it as a promising compound for formulation and drug delivery research. |
