α-Conotoxin MII 是可从僧袍芋螺中分离得到的一种天然产物，有效抑制 nAChR 受体的α3β2亚基，IC50值为 0.5 nM。它还可有效抑制 β3-containing 神经尼古丁受体。

α-Conotoxin MII acetate 是一种来自海洋蜗牛 Conus magus 毒液的 16 个氨基酸肽。它有效阻断由 α3β2 亚基组成的烟碱型乙酰胆碱受体，IC50 为 0.5 nM。 它可有效阻断含 β3 的神经元烟碱乙酰胆碱受体。

AT-1001 is an α3β4 nAChR partial agonist. AT-1001 attenuates stress-induced reinstatement of nicotine seeking in a rat model of relapse and induces minimal withdrawal in dependent rats. AT-1001 also potently and reversibly blocks epibatidine-induced inward currents in HEK cells transfected with α3β4 nAChR. Importantly, AT-1001 potently and dose-dependently blocks nicotine self-administration in rats, without affecting food responding. When tested in a nucleus accumbens (NAcs) synaptosomal preparation, AT-1001 inhibits nicotine-induced [³H]dopamine release poorly and at significantly higher concentrations compared with mecamylamine and conotoxin MII.

α-Conotoxin MII TFA (α-CTxMII TFA) 是可从海螺 Conus magus 中分离得到，有效抑制 nAChR 受体的α3β2亚基，其 IC50值为 0.5 nM。α-Conotoxin MII TFA (α-CTxMII TFA) 可有效抑制 β3-containing 神经尼古丁受体。
