Metabolite Identification
Common Name7-Amino-4-methylcoumarin
Description7-Amino-4-methylcoumarin, also known as coumarin C440 or 4-methyl-7-aminocoumarin, belongs to the class of organic compounds known as coumarins and derivatives. These are polycyclic aromatic compounds containing a 1-benzopyran moiety with a ketone group at the C2 carbon atom (1-benzopyran-2-one). Based on a literature review very few articles have been published on 7-Amino-4-methylcoumarin. This compound has been identified in human blood as reported by (PMID: 31557052 ). 7-amino-4-methylcoumarin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 7-Amino-4-methylcoumarin is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.

Specific function:
Serine protease (PubMed:10103041, PubMed:7763554). Hydrolyzes azocasein (PubMed:10103041). Cleaves peptide bonds of the oxidized insulin B chain preferably at 15-Leu-|-Tyr-16, but also at 4-Gln-|-His-5 and 24-Phe-|-Phe-25, and to a lesser extent at 5-His-|-Leu-6 and 25-Phe-|-Tyr-26. Hydrolyzes amide bonds between amino acids and 7-amino-4-methylcoumarin (AMC) in vitro (PubMed:7763554).
