BQ-869 is an NMDA receptor antagonist related to dizocilpine (MK-801).[1][2] It is described as a derivative of dizocilpine and has shown higher potency in comparison.[2] The drug shows neuroprotective effects in rodents, for instance against stroke and cerebral ischemia.[1][2] It is described as being "extremely potent" and was said to be "the most potent antagonist of NMDA receptors".[2] However, this was not based on standard affinity or functional assays for establishing potency.[2] BQ-869 was described in the scientific literature by Guo Yu and colleagues in Shanghai, China in 2015.[2]
