Metabolite Identification
Common Name1-O-Hexyl-2,3,5-trimethylhydroquinone
DescriptionHX-1171, also known as HTHQ-2,3,5, belongs to the class of organic compounds known as 4-alkoxyphenols. These are phenols that carry an alkoxy group at the 4-position of the benzene ring. HX-1171 is an extremely weak basic (essentially neutral) compound (based on its pKa). Hx 1171 is under investigation in clinical trial NCT01548391 (A Phase I Clinical Study Study of the Safety, Tolerability, and Pharmacokinetics of HX-1171 in Healthy Male Subjects). This compound has been identified in human blood as reported by (PMID: 31557052 ). 1-o-hexyl-2,3,5-trimethylhydroquinone is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 1-O-Hexyl-2,3,5-trimethylhydroquinone 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.
