Dehydrosafynol
Dehydrosafynol, also known as (2r,11e)-11-tridecene-3,5,7,9-tetrayne-1,2-diol, is a member of the class of compounds known as long-chain fatty alcohols. Long-chain fatty alcohols are fatty alcohols that have an aliphatic tail of 13 to 21 carbon atoms. Thus, dehydrosafynol is considered to be a fatty alcohol lipid molecule. Dehydrosafynol is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Dehydrosafynol can be found in safflower, which makes dehydrosafynol a potential biomarker for the consumption of this food product.
5-Acetylamino-6-amino-3-methyluracil
5-Acetylamino-6-amino-3-methyluracil (AAMU) is one of caffeine major metabolites. Analysis of caffeine and its metabolites is of interest with respect to caffeine exposure, for kinetic and metabolism studies and for opportunistic in vivo estimation of drug metabolizing enzyme activity in humans and animals. Urinary caffeine metabolite ratios are used in humans to assess the activity of cytochrome P450 1A2 (CYP1A2), xanthine oxidase and N-acetyltransferase 2 (NAT2), which are involved in the activation or detoxification of various xenobiotic compounds, including carcinogens. Investigating the activity of these enzymes is of clinical relevance for assessing intra- and inter-individual differences in NAT2- and CYP1A2-mediated drug metabolism, and for evaluating the risk of developing specific exposure-related diseases.
