Study of molecular docking of mu opioid receptor agonist---fentanyl and its analogs based on Docking

摘要

The interaction mechanism of a series of fentanyl analogs are examined using molecular docking to the mu-opioid receptor based on Surflex-Docking. Fully automatic flexible molecular docking (Surflex-Docking) was performed by using the possible active conformations of 70 fentanyl analogs and optimized 3D structure of mu-opioid receptor. The site mainly consist of residues ILE 109, ASP 112, TYR113, MET116, HIS262, TYR291. All these residues take part in interaction between fentanyl and mu-opioid receptor. Meanwhile, the results provide new insight to design of experiments aimed at understanding the structure.
