Common NameN,N'-Di-1,2,3,4-Tetrahydroacridin-9-Ylheptane-1,7-Diamine
Descriptionbis(7)-tacrine, also known as B7T, belongs to the class of organic compounds known as acridines. These are organic compounds containing the acridine moiety, a linear tricyclic heterocycle which consists of two benzene rings joined by a pyridine ring. Bis(7)-tacrine is an acetylcholinesterase (AChE)inhibitor (IC50 0.40 nM, >1,000 times more potent than tacrine). bis(7)-tacrine is a very strong basic compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). N,n'-di-1,2,3,4-tetrahydroacridin-9-ylheptane-1,7-diamine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically N,N'-Di-1,2,3,4-Tetrahydroacridin-9-Ylheptane-1,7-Diamine 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.
