Figure 4.

Predicted binding mode and predicted intermolecular interactions of the selected major compounds in Gaultheria pumila berries extract and the residues of the Torpedo Californica acetylcholinesterase (TcAChE) catalytic site. Yellow dotted lines indicate hydrogen bond interactions and cyan dotted lines represent π–π interactions. (A) Scupolin I in the catalytic site; (B) Unedide in the catalytic site; (C) Nuzhenal B in the catalytic site; (D) Myricetin O-rhamnoside in the catalytic site; and (E) Luteolin 7-glucuronide in the catalytic site.
