FIELD: medicine.
SUBSTANCE: invention refers to biotechnology, namely a new alpha-conotoxin PnIA analogue showing high affinity and selectivity to acetylcholine-binding protein (ACBP) form Aplysia californica. The peptide has an amino acid sequence: GCCSHPPCAANNPDYC-NH2 (SEQ ID NO:1) and contains two intramolecular disulphide bonds between Cys2 and Cys8, Cys3 and Cys16.
EFFECT: invention allows extending the range the substances which appear to be competitive antagonists of acetylcholine nicotinic receptor.
