Structural interactions of FMNT with NMDA receptor and CBP. a Structural representation of FMNT binding to NMDA receptor (PDB:4PE5; GluN2B: blue ribbon; GluN1a: red ribbon) as inferred from docking simulations (left). Ifenprodil was shown as green sticks, and FMNT was shown as cyan sticks (right). The -OH group of FMNT formed hydrogen-bond with Glu236 of NMDA receptor (red arrow in right). The best-docked pose of FMNT in the active site coincided well with the crystal ligand ifenprodil (NMDA antagonist). b 2D diagram of interaction between FMNT and NMDA receptor showed the major binding sites and bonding forces. c Characterization of spatial interactions within the FMNT-CBP (PDB:5CGP, CBP: bluish violet ribbon) complex (left). FMNT was shown as cyan sticks (top-right) and crystal ligand BDOIA383 (ligand of CBP) was shown as green sticks (bottom-right). The -OH group of the FMNT formed hydrogen-bond with Met1160 of CBP (red arrow in the top-right). d 2D diagram showed the major binding sites and bonding forces between FMNT and CBP
