Hansruedi Glatt,Heiner Boeing,Christina E.H Engelke,Lan Ma,Andreas Kuhlow,Ulrike Pabel,Doreen Pomplun,Wera Teubner,Walter Meinl +8 more
TL;DR: Cytosolic sulphotransferases transfer the sulpho moiety from the cofactor 5'-phosphoadenosine-3-phosphosulphate to nucleophilic groups of xenobiotics and small endogenous compounds (such as hormones and neurotransmitters).

Extractionless method for the determination of urinary caffeine metabolites using high-performance liquid chromatography coupled with tandem mass spectrometry.
TL;DR: An HPLC-electrospray-MS-MS method for the determination of 11 caffeine metabolites and two internal standards after a simple, extractionless preparation is developed and demonstrated the simplicity, high sensitivity and selectivity of the method under conditions used for phenotyping.

Ethanol Enhances the Activation of 1-Hydroxymethylpyrene to DNA Adduct-Forming Species in the Rat
TL;DR: Interaction with other chemicals may dramatically affect the toxicological effects of some polycyclic aromatic carcinogens, and the effect of ethanol may be relevant for some human exposures to poly cyclic aromatic compounds.

Detection of Mercapturic Acids and Nucleoside Adducts in Blood, Urine and Feces of Rats Treated with Metabolites of Methylpyrene
TL;DR: Sensitive HPLC-MS/MS methods were designed to determine levels of MPMA and MPdG in biological samples and found that shortly after administration of HMP to rats, MPMA was detected in blood and was then excreted in urine and feces, chiefly within 24 h.
