potent partial agonists of the α7 receptor, selective against other nicotinic receptors and the serotinergic 5HT3A receptor. (1'S,3'R,4'S)-N-(6-phenylpyrimidin-4-yl)-4H-1'-azaspiro[oxazole-5,3'-bicyclo[2.2.2]octan]-2-amine, a potent and selective α7 nAChR partial agonist, was demonstrated to improve cognition in the mouse novel object recognition (NOR) model of episodic memory.
如该系列以前的报告所述,含奎尼丁的螺环恶唑啉已证明可作为α7烟碱乙酰胆碱受体(α7nAChR)部分激动剂使用。在这项工作中,该化学型的SAR被扩展为包括一系列的二嗪杂环取代。许多杂环类似物是α7受体的有效部分激动剂,对其他烟碱类受体和血清素5HT3A受体具有选择性。(1'S,3'R,4'S)-N-(6-苯基嘧啶-4-基)-4H-1'-氮杂螺[恶唑-5,3'-双环[2.2.2]正辛] -2-胺,a有效和选择性的α7nAChR部分激动剂,被证明可以改善情节记忆的小鼠新对象识别(NOR)模型中的认知。
