influences of the 3,6-diazabicyclo[3.2.0]heptane core. Small 5-substituents on the pyridine ring had a modest impact on the binding affinities and functional activities. 6-Bromo, 6-chloro, and 6-methyl substituents on the pyridine ring led to increased binding affinities and improved functional activities. Most of the 6-N-pyridinyl-substituted 3,6-diazabicyclo[3.2.0]heptanes are selective for the alpha4beta2
合成了一系列从3,6-二氮杂双环[3.2.0]庚烷衍生的新型有效神经元烟碱乙酰胆碱受体(nAChR)配体,并评估了其对alpha4beta2 nAChR亚型的结合亲和力和激动剂活性。这些新型nAChR配体的结构活性关系研究集中于对吡啶环的取代作用以及3,6-二氮杂双环[3.2.0]庚烷核心的立体和区域化学影响。吡啶环上的5个小取代基对结合亲和力和功能活性影响不大。吡啶环上的6-溴,6-氯和6-甲基取代基导致增加的结合亲和力和改善的功能活性。大多数6-N-吡啶基取代的3,6-二氮杂双环[3.2.0]庚烷对alpha4beta2 nAChR亚型具有选择性。化合物(1R,5S)-25,(1R,5S)-55,和(1R,5S)-56在halpha3beta4 nAChR上几乎没有活性,但在halpha4beta2 nAChR亚型上保留了效力和功效。3-N-吡啶基取代的系列显示出更复杂的SAR。发现(
