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.

Thiolutin
Thiolutin is found in alcoholic beverages. Thiolutin is isolated from several strains of Streptomyces albus and Streptomyces pimprina. Antibiotic which inhibits microbiological growth in beer Some sources erroneously specify "aureothricin" as a synonym of thiolutin. Aureothricin is an antibiotic very similar to Thiolutin, and is created as a by-product during the Thiolutin fermentation. Thiolutin is a sulfur-containing antibiotic, which is a potent inhibitor of bacterial and yeast RNA polymerases. It was found to inhibit in vitro RNA synthesis directed by all three yeast RNA polymerases (I, II, and III). Thiolutin is also an inhibitor of mannan and glucan formation in Saccharomyces cerevisiae and used for the analysis of mRNA stability. Studies have shown that thiolutin inhibits adhesion of human umbilical vein endothelial cells (HUVECs) to vitronectin and thus suppresses tumor cell-induced angiogenesis in vivo Isolated from several strains of Streptomyces albus and Streptomyces pimprina. Antibiotic which inhibits microbiological growth in beer C471 - Enzyme Inhibitor > C25995 - RNA Polymerase Inhibitor C254 - Anti-Infective Agent > C258 - Antibiotic Thiolutin (Acetopyrrothin) is a disulfide-containing antibiotic and anti-angiogenic compound produced by Streptomyces. Thiolutin inhibits the JAMM metalloproteases Csn5, Associated-molecule-with-the-SH3-Domain-of-STAM (AMSH) and Brcc36[1]. Thiolutin is a potent and selective inhibitor of endothelial cell adhesion accompanied by rapid induction of Heat-shock protein beta-1 (Hsp27) phosphorylation[2].
