D-α-Tocopherol polyethylene glycol 1000 succinate has been used as an emulsifier in the preparation of Poly(lactic-co-glycolic acid) (PLGA) particle as synthetic DNA carriers by double emulsion (w1/o/w2) and nanoprecipitation method.

Biochem/physiol Actions

D-α-Tocopherol polyethylene glycol 1000 succinate (TPGS) also known as vitamin E TPGS, is a therapeutic agent for vitamin E deficiency in children, administered during chronic childhood cholestasis. 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.
Tocopherols (TCP) (vitamin E) are a series (α, β, γ and δ) 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.
