Common NameEliprodil
DescriptionEliprodil belongs to the class of organic compounds known as 4-benzylpiperidines. These are organic compounds containing a benzyl group attached to the 4-position of a piperidine. Eliprodil failed a Phase III clinical trial for the treatment of acute ischemic stroke in 1996, sponsored by Synthélabo Recherche. Eliprodil is a very strong basic compound (based on its pKa). Eliprodil (codenamed SL-82.0715) is an NMDA antagonist drug candidate which selectively inhibits the NR2B (GLUN2B) subtype NMDA receptor at submicromolar concentrations. Therefore, when NMDA receptors are activated, there is an increase in intracellular Ca2+ concentration. NMDA receptors are a key component in mediating glutamate-induced excitotoxicity, and it is believed that NMDA antagonists would be neuroprotective after a stroke or other traumatic brain injury. These neurons quickly lose ATP and become depolarized, which releases glutamate. This, in turn, causes an influx of Na+ and Ca2+. After a traumatic brain injury, neurons become deprived of glucose and oxygen. High Ca2+ causes fatal metabolic consequences, including neuronal cell death. This compound has been identified in human blood as reported by (PMID: 31557052 ). Eliprodil is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Eliprodil 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.
