“…Molecular docking of pitolisant as reference molecule was performed based on the identified key residues in the binding site resulting in docking comparable to those reported elsewhere (Kuder et al., ; Łażewska et al., ; Levoin et al., ; Morini et al., ). These amino acids might be the key residues of the binding site of H 3 R important for ligand binding as evidenced in several previously published reports (Axe, Bembenek, & Szalma, ; Kuder et al., ; Łażewska et al., ; Levoin et al., ; Morini et al., ; Schwartz, ). As structure‐based virtual screening method, the pharmacophore model of the receptor complex outlined above was generated by LigandScout and applied to online ZINCPharmer web server (Figure ).…”
