Tri- and tetracyclic nitrogen-bridgehead compounds were designed and synthesized to yield micromolar cholinesterase (ChE) inhibitors. Structure–activity relationships identified potent compounds with butyrylcholinesterase selectivity. These compounds were selected as starting points for the design and synthesis of carbamate-based (pseudo)irreversible inhibitors. Compounds with superior inhibitory activity
三环和四环氮桥头化合物被设计和合成以产生微摩尔胆碱酯酶 (ChE) 抑制剂。构效关系确定了具有丁酰胆碱酯酶选择性的有效化合物。选择这些化合物作为设计和合成基于氨基甲酸酯的(伪)不可逆抑制剂的起点。获得了具有优异抑制活性和选择性的化合物,并且还对酶氨基甲酰化的速度进行了动力学表征。在谷氨酸诱导的细胞内活性氧生成后,鉴定并引入了对海马神经元细胞系 (HT-22) 显示出神经保护特性的结构元件。
