We previously showed that alpha- and gamma-tocotrienols accumulate in adipose tissue and skin but not in plasma or other tissues of rats fed a tocotrienol-rich fraction extracted from palm oil containing alpha-tocopherol and alpha- and gamma-tocotrie

Deuterium-labelled coenzyme Q10 ([2-CD3-1′-CD2]coenzyme Q10, coenzyme Q10-d5 ) was synthesized by condensation of 2,3-dimethoxy-[5-CD3]methyl-1, 4-hydroquinone with [1-CD2]decaprenol. Five positions were selected for deuteration as replacement at t

In this study, we investigated a change in the excretory content of 2,7,8-trimethyl-2(2'-carboxyethyl)-6-hydroxychroman (gamma-CEHC), a gamma-tocopherol (gamma-Toc) metabolite, in rat urine and bile by using a new high-performance liquid chromatograp

The modification of sodium bis(2-methoxyethoxy)aluminum hydride (SMEAH) with pyrrolidine provided a highly selective reducing agent to transform N -benzyl-4-ethoxycarbonylpiperidine into N -benzyl-4-formylpiperidine 1 under mild conditions. However,

A method for the enantiomeric determination of 2,7,8-trimethyl-2-(β-carboxyethyl)-6-hydroxy chroman (LLU-α, γ-CEHC) in rat plasma was developed using high-performance liquid chromatography (HPLC) with a fluorimetric derivatization with 4-N, N-dime

[11C]Coenzyme Q10 was synthesized by O-methylation of 3-demethyl coenzyme Q10 with 11CH3I. We have produced 1–4 mCi of [11C]coenzyme Q10 with radiochemical yields of 6–16 % (based on trapping 11CH3I) in 35–50 min with radiochemical purities of
