which are potent in vitro at human and rat H(3) receptors, with K(i) values of 0.1-5.8 nM. Analogues were discovered with potent (0.01-1 mg/kg) cognition and attention enhancing properties in animal models. One compound in particular, 4-(2-[2-(2(R)-methylpyrrolidin-1-yl)ethyl]benzofuran-5-yl)benzonitrile (ABT-239), combined potent and selective H(3) receptor antagonism and excellent pharmacokinetic and
已发现基于2-氨基乙基苯并呋喃骨架的H(3)受体拮抗剂,在人和大鼠的H(3)受体中具有很强的体外作用力,K(i)值为0.1-5.8 nM。在动物模型中发现具有有效(0.01-1 mg / kg)认知和注意力增强特性的类似物。一种化合物,特别是4-(2- [2-(2(R)-甲基吡咯烷-1-基)乙基]苯并呋喃-5-基)苄腈(ABT-239),具有有效和选择性的H(3)受体拮抗作用以及跨物种优异的药代动力学和代谢特性,在两种行为模型中均具有完整的功效:大鼠幼崽以0.1 mg / kg的五次试验性避免回避获取模型和成年大鼠以0.01 mg / kg的社交认知记忆模型。此外,与基于中枢神经系统的副作用相比,该化合物不刺激运动活性,并且对诱导行为功效具有很高的选择性。该化合物及其类似物的效能和选择性支持H(3)受体拮抗剂治疗认知功能障碍的潜力。
