BMT-108908 is a negative allosteric modulator with selective activity on the NR2B subtype of the NMDA receptor. BMT-108908 has been shown to damage cognition in research, affecting cognitive functions in multiple areas. BMT-108908 failed to show a significant impact on the γ wave power of the EEG in the experiment, but it had a significant inhibitory and enhancement effect on the β wave and δ wave power. The effects of BMT-108908 differ from those of other NMDA receptor channel blockers such as ketamine and lanimol.
