产品描述

α-Conotoxin AuIB is a conotoxin that has been found inC. aulicusand has receptor antagonist and analgesic activity.1It is a peptide antagonist of α3β4 subunit-containing nicotinic acetylcholine receptors (nAChRs; IC50= 0.75 µM). It is greater than 100-fold selective for α3β4 subunit-containing nAChRs over those containing α2β2, α2β4, α3β2, α4β2, α4β4, or α1β1γδ subunits but does inhibit homomeric α7 nAChRs by 34% at 3 µM. Intrathecal administration of α-conotoxin AuIB (0.2 and 2 nmol/animal) reduces mechanical allodynia in a rat model of neuropathic pain induced by partial sciatic nerve ligation.2It also reverses somatic signs of withdrawal in a mouse model of morphine withdrawal when administered intracerebroventricularly at doses of 1.75 and 3.5 pmol/animal.3
