A series of cyclic acyl guanidine with carbamate moieties have been synthesized and evaluated in vitro for their AChE and BChE inhibitory activities. Structure−activity relationships identified compound 23 as a nanomolar and selective BChE inhibitor, while compound 32 exhibited nanomolar and selective AChE inhibition, selectivity depending on both the structure of the carbamate substituent as well
合成了一系列具有氨基甲酸酯部分的环状酰基胍,并在体外对其AChE和BChE抑制活性进行了评估。构效关系确定了化合物23为纳摩尔和选择性的BChE抑制剂,而化合物32表现为纳摩尔和选择性的AChE抑制作用,其选择性取决于氨基甲酸酯取代基的结构以及胍-N的位置代换。分析了酶氨基甲酰化的速度,并显示了与毒扁豆碱相似的行为。氨基甲酸酯转移到胆碱酯酶的活性位点后形成的酚类化合物,在谷氨酸诱导细胞内活性氧生成后,对海马神经元细胞系(HT-22)具有额外的神经保护作用。
