Background:

α-Conotoxin ImI is a conotoxin that has been found inC. imperialisand has receptor antagonist and anticancer activities.1It is a peptide antagonist of homomeric α7 nicotinic acetylcholine receptors (nAChRs; IC50= 220 nM). α-Conotoxin ImI is selective for α7 nAChRs over α2β2, α3β2, α4β2, α2β4, α3β4, α4β4, and α1β1γδ subunit-containing nAChRs at 5 µM but does inhibit homomeric α9 nAChRs (IC50= 1,800 nM). Administration of paclitaxel in micelles containing α-conotoxin ImI decreases tumor growth in an MCF-7 mouse xenograft model.2Intracerebroventricular, but not intraperitoneal, administration of α-conotoxin ImI (20 nmol/animal) induces seizures in rats.3
