7 Within the core of spiral beta-strands-1-5 of LBD-GLUN1 pocket, all-atom molecular dynamics simulation revealed that nefiracetam disrupts Arg523-glycine-Asp732 interaction resulting in open GLUN1 conformation and ultimate diffusion of glycine out of the clamshell cleft. Glycine glutamate ionotropic receptor NMDA type subunit 1 Homo sapiens
