Metabolite Identification
Common NameRacemethorphan
DescriptionCHEMBL22207, also known as levomethorphan or delsym, belongs to the class of organic compounds known as morphinans. These are polycyclic compounds with a four-ring skeleton with three condensed six-member rings forming a partially hydrogenated phenanthrene moiety, one of which is aromatic while the two others are alicyclic. CHEMBL22207 is a very strong basic compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). Racemethorphan is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Racemethorphan 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.
