mecamylamine

Mecamylamine 是一种具有口服活性，非选择性，非竞争性的nAChR 拮抗剂。Mecamylamine 也是一种神经节阻滞剂，可穿过血脑屏障。Mecamylamine 可用于神经疾病，高血压，抗抑郁的研究。

Dexmecamylamine( TC-5214, NIH-11008) is used as a nicotinic channel modulator with antidepressant activity.

Dexmecamylamine ((+)-Mecamylamine) 是一种烟碱乙酰胆碱受体 (nAChR) 的拮抗剂，对 α3β4 α4β2 α7 α1β1γδ 受体具有拮抗作用，IC50 在微摩尔范围内。该化合物表现出抗焦虑和抗抑郁样活性。

Mecamylamine hydrochloride (Mevasin) 是一种易穿过血脑屏障的烟碱拮抗剂，用作高血压的神经节阻滞剂，具有抗神经疾病作用。

Unifiram 是一种认知增强剂。 Unifiram 诱导大鼠海马 CA1 区场兴奋性突触后电位 (fEPSP) 幅度的持久增加 (EC50= 27 nM) 并增加大鼠大脑皮层中乙酰胆碱 (ACh) 的释放。

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.
