Abstract
The present invention provides a novel α-conotoxin peptide, pharmaceutical composition and use thereof. The present invention further provides a propeptide of the conotoxin peptide, a nucleic acid construct, expression vector and transformed cell of the conotoxin peptide as well as a fused protein of the conotoxin peptide. The present invention discloses a method for blocking acetylcholine receptors as well as a use of the conotoxin peptide in the manufacture of a medicament. The α-conotoxin peptide of the present invention can specifically block acetylcholine receptor (nAChRs, such as α3β2 nAChRs, α6/α3β2β3 nAChR or α3β4 nAChR or α6/α3β4 nAChR), has activity for treatment of neuralgia, addiction, Parkinson's disease, dementia, schizophrenia, cancers, and can be used in the manufacture of a medicament for analgesia and smoking cessation and drug-withdrawal, a medicament for treatment of mental diseases and cancers, as well as a tool drug for neurosciences.
