α-Conotoxin Im-I-Get quote

Description

α-Conotoxin Im-I is a selective α7/α9 nAChR antagonist, blocking α7 nicotinic receptors with the highest apparent affinity, while having an 8-fold lower affinity for homomeric α9 nicotinic receptors. α-Conotoxin Im-I is toxic and induces seizures in rodents. α-Conotoxin Im-I is a tool for studying neuronal nAChR[1][2].—–C52H78N20O15S4—-[1]Johnson DS, et al. alpha-Conotoxin ImI exhibits subtype-specific nicotinic acetylcholine receptor blockade: preferential inhibition of homomeric alpha 7 and alpha 9 receptors. |[2]Quiram P A, et al.
