Metabolite Identification
Common NameMepindolol
DescriptionMepindolol, also known as SH e 222 or corindolan, belongs to the class of organic compounds known as indoles. Indoles are compounds containing an indole moiety, which consists of pyrrole ring fused to benzene to form 2,3-benzopyrrole. Mepindolol is a very strong basic compound (based on its pKa). Mepindolol (Betagon) is a non-selective beta blocker. This compound has been identified in human blood as reported by (PMID: 31557052 ). Mepindolol is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Mepindolol 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.
