Xenobiotics are foreign chemicals, which can be toxic or harmless. These xenobiotics include not only drugs but also dietary supplement, food additives, and environmental pollutants. When xenobiotics greatly disrupt the metabolism and transport of endogenous compounds into the body, they can be harmful to human bodies. Xenobiotics can be eliminated unchanged, but mostly they can be metabolized by metabolism enzymes in vivo. Studying how xenobiotic metabolism occurs in the human body helps us to accelerate researches in drug discovery and toxicology. In drug discovery, understanding the metabolites of drugs helps us to study what effects they have. Moreover, metabolism can cause unwanted side effects, thus understanding the metabolism of all types of chemicals is important in the field of toxicology. Metabolomics, the comprehensive analysis of small molecules, is an ideal tool to systematically profile the endogenous metabolites. There are many applications of metabolomics in xenobiotic studies, such as acetaminophen (APAP) metabolism, cyclophosphamide (CP) and ifosfamide (IF) metabolism.
