enzyme inhibition activity were examined. The novel Schiff bases and their amine derivatives (1a–d, 2a–d, 3b–d, 4a–c, 5a–c, 6a, 6c, 6d) were effective inhibitors of the cytosolic carbonic anhydrase I and II isoforms (hCA I and II), and acetylcholinesterase (AChE) with Ki values in the range of 159.43 ± 30.03 to 563.73 ± 115.30 nM for hCA I, 104.88 ± 18.44 to 524.32 ± 95.03 nM for hCA II, and 3.95 ± 0.74
由 1,2-二氨基乙烷、1,3-二氨基丙烷和 1,4-二氨基丁烷和取代的苯甲醛合成三个系列的对称席夫碱,并用硼氢化钠还原为相应的苄基二胺 4-6。使用元素分析、FT-IR、1H NMR和13C NMR光谱对获得的所有化合物进行表征。测试了这些化合物的酶抑制特性,并检查了烷烃链长度和苯基上的取代基对酶抑制活性的影响。新型席夫碱及其胺衍生物(1a-d、2a-d、3b-d、4a-c、5a-c、6a、6c、6d)是胞质碳酸酐酶 I 和 II 亚型(hCA I)的有效抑制剂和 II),以及乙酰胆碱酯酶 (AChE),对于 hCA I,Ki 值在 159.43 ± 30.03 至 563.73 ± 115.30 nM 范围内,104.88 ± 18。
