cognitive decline in Alzheimer’s disease. A set of pseudo-irreversible BChE inhibitors with high selectivity over hAChE was synthesized based on carbamates attached to tetrahydroquinazoline scaffolds with the 2-thiophenyl compound 2p as the most potent inhibitor of eqBChE (KC = 14.3 nM) and also of hBChE (KC = 19.7 nM). The inhibitors transfer the carbamate moiety onto the active site under release of the
丁酰胆碱酯酶(BChE)是治疗阿尔茨海默氏病晚期认知功能下降的有希望的靶标。一组与在高选择性伪不可逆的BChE抑制剂ħ胆碱酯酶合成基于附加到四氢支架与2-噻吩基化合物氨基甲酸酯2P为一体的最有效的抑制剂当量的BChE(ķ ç = 14.3 nM)的和也ħ的BChE (K C= 19.7 nM)。抑制剂在本身充当神经保护剂的酚类四氢喹唑啉支架释放下,将氨基甲酸酯部分转移到活性位点上。通过将动力学数据与分子对接研究相结合,探索了一种可能的结合模型,该模型描述了四氢喹唑啉支架如何将氨基甲酸酯引导至接近活性位点的位置。该模型解释了在氨基甲酸酯转移之前载体支架对抑制剂亲和力的影响。该策略可用于利用其他基于氨基甲酸酯的抑制剂的结合模式。
