Abstract: The invention relates to a polyamide compound and a use thereof. Specifically, the invention relates to a type of polyamide compound (which preferably comprise one or more amide bonds formed by condensation of same or different L-amino acids or D-amino acids), or stereoisomers, crystalline polymorphs, solvates, metabolites, prodrugs or pharmaceutically acceptable salts or esters thereof, or pharmaceutical compositions thereof, as well as a method for preparing the polyamide compound and a use thereof in the prevention or treatment of diseases associated with ?-opioid receptor. The polyamide compound of the invention has excellent ?-opioid receptor agonistic activity and hydrophilicity, thus having a lesser ability of penetrating the blood-brain barrier and a lower capacity for entering the brain.
