α-C-1-Chromanol, 2,2,5,7,8-Pentamethyl-3,4-dihydrochromen-6-ol, 2,2,5,7,8-Pentamethyl-6-hydroxychroman, 3,4-Dihydro-2,2,5,7,8-pentamethyl-2H-1-benzopyran-6-ol, 6-Hydroxy-2,2,5,7,8-pentamethylchroman
一般描述
2,2,5,7,8-Pentamethyl-6-chromanol has been reported as an vitamin E model compound. It undergoes oxidation in presence of various alcohols, ranging from methanol to cholesterol, affords 5-alkoxymethyl-2,2,7,8-tetramethyl-6-chromanols. Antioxidant moiety of vitamin E, 2,2,5,7,8-pentamethyl-6-chromanol (PMCol), is reported to have antiandrogen activity in prostate carcinoma cells.
应用
2,2,5,7,8-Pentamethyl-6-chromanol is the suitable reagent used for the quantitative analysis of α-tocopherol by plasma-based gas chromatography/tandem mass spectrometry (GC/MS/MS) using a tabletop quadrupole ion trap mass spectrometer. It may be employed as α-tocopherol model compound and on oxidation by t-butyl hydroperoxide in chloroform, in the presence of alcohol, affords 5-alkoxymethyl-2,2,7,8-tetramethyl-6-chromanol. It may be used as internal standard for the determination of α- and γ-tocopherol in the rabbit serum and liver by HPLC.

Singlet oxygen quenching rate constants for tocopherol and tocotrienol homologues have been determined in organic solvents of different polarities, as well as for other biological prenyllipids such as plastoquinol, ubiquinol, and alpha-tocopherolquinol. The obtained results showed that the quenching activity
