Metabolite Identification
Common Name3-Desmethylcolchicine
DescriptionN-(3-hydroxy-1,2,10-trimethoxy-9-oxo-6,7-dihydro-5H-benzo[a]heptalen-7-yl)acetamide belongs to the class of organic compounds known as tropones. Tropones are compounds containing a tropone ring, which is a cycloheptatrienone ring bearing a ketone group. N-(3-hydroxy-1,2,10-trimethoxy-9-oxo-6,7-dihydro-5H-benzo[a]heptalen-7-yl)acetamide is an extremely weak basic (essentially neutral) compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). 3-desmethylcolchicine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 3-Desmethylcolchicine 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.
