Abstract

The invention discloses an anti-opioid peptide, antagonist peptide and application thereof. The anti-opioid peptide is polypeptide formed by the way that one of the following amino acid residue sequences: 1) SEQ ID NO: 1 in the sequence table; 2) SEQ ID NO: 3-5; 3) amino acid residue sequences of SEQ ID NO: 1, SEQ ID NO: 3-5 in the sequence table are subject to substitution, deletion or addition of one to ten amino acid residues to have antagonist morphine anti-harm effect. The antagonist peptide thereof is polypeptide formed by the way that one of the following amino acid residue sequences: 1) SEQ ID NO: 9-11 in the sequence table; 2) amino acid residue sequences of SEQ ID NO: 9-11 in the sequence table is subject to substitution, deletion or addition of one to ten amino acid residues to have effects of enhancing morphine analgesia, reversing morphine tolerance and / or reducing or eliminating abstinence symptom. The anti-opioid peptide and active segment thereof and antagonist peptide can play important role in the medicinal and rehabilitation medicine preparation field and has wide application prospect.
