Metabolite Identification
Common NameIpidacrine
DescriptionIpidacrine belongs to the class of organic compounds known as aminoquinolines and derivatives. These are organic compounds containing an amino group attached to a quinoline ring system. Ipidacrine is a very strong basic compound (based on its pKa). This compound is a ring-constricted derivative of tacrine (Cognex). Ipidacrine (Neiromidin) is a drug first synthesized by the National Research Center for Biologically Active Compounds in the Russian Federation. Ipidacrine directly stimulates impulse transmission in the central nervous system and neuromuscular synapses by blocking membrane potassium channels. Ipidacrine is a reversible acetylcholinesterase inhibitor used in memory disorders of different origins. Ipidacrine enhances not only choline, but also adrenaline, serotonin, histamine, and oxytocin effects on smooth muscle. This compound has been identified in human blood as reported by (PMID: 31557052 ). Ipidacrine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Ipidacrine 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.
