  A method for the analysis of intact glucuronides and sulfates of common neurotransmitters serotonin (5-HT) and dopamine (DA) as well as of 5-hydroxy-3-indoleacetic acid (5-HIAA), 3,4-dihydroxyphenylacetic acid (DOPAC), and homovanillic acid (HVA) in rat brain microdialysates by liquid chromatography−tandem mass spectrometry (LC−MS/MS) was developed. Enzyme-assisted synthesis using rat liver microsomes as a biocatalyst was employed for the production of 5-HT-, 5-HIAA-, DOPAC-, and HVA-glucuronides for reference compounds. The sulfate conjugates were synthesized either chemically or enzymatically using a rat liver S9 fraction. The LC−MS/MS method was validated by determining the limits of detection and quantitation, linearity, and repeatability for the quantitative analysis of 5-HT and DA and their glucuronides, as well as of 5-HIAA, DOPAC, and HVA and their sulfate-conjugates. In this study, 5-HT-glucuronide was for the first time detected in rat brain. The concentration of 5-HT-glucuronide (1.0−1.7 nM) was up to 2.5 times higher than that of free 5-HT (0.4−2.1 nM) in rat brain microdialysates, whereas the concentration of DA-glucuronide (1.0−1.4 nM) was at the same level or lower than the free DA (1.2−2.4 nM). The acidic metabolites of neurotransmitters, 5-HIAA, HVA, and DOPAC, were found in free and sulfated form, whereas their glucuronidation was not observed.

  The growing interest in the bioactivity of natural polyphenols and of their metabolites requires metabolites to be used in bioassays and as standards in research protocols. We report here on the synthesis of several hydroxytyrosol metabolite monosulfates achieved using a simplified protocol with improved yields. A synthetic solution based on avoidance of high temperature conditions during the synthesis and of low pressure conditions during purification has been established. Monosulfates of several phenolic compounds, namely, hydroxytyrosol, hydroxytyrosol acetate, homovanillyl alcohol, homovanillyl alcohol acetate, homovanillic acid, ferulic acid, and 3,4-dihydroxyphenylethanoic acid, were efficiently synthesized in 1-2 steps in good yield and isolated using simple procedures. The proposed protocol was shown to be relatively rapid, efficient, cheap, and widely applicable to a number of catechol scaffolds.
