series of benzimidazolone bridged triheterocyclic compounds bearing thiosemicarbazide, thiadiazole, triazole, moieties was synthesized and then screened for their in vitro urease, α-glucosidase, and acetylcholinesterase inhibition properties for the first time. All the synthesized compounds showed an outstanding urease inhibitory effect when compared with standards. Compounds 1, 4, 5b, 5d, 6b, 6d, 7b
合成了一系列新的带有氨基硫脲、噻二唑、三唑部分的苯并咪唑酮桥连三杂环化合物,然后首次筛选了它们的体外脲酶、α-葡萄糖苷酶和乙酰胆碱酯酶抑制特性。与标准品相比,所有合成的化合物均显示出突出的脲酶抑制作用。化合物1,4,图5b,图5d,图6b,图6d,图7b,和图7D显示出乙酰胆碱酯酶显著抑制活性用IC 50值7.32±0.58和12.52±0.13之间微克/毫升媲美多奈哌齐(15.12±0.20微克/毫升)。化合物5c在苯并咪唑酮核的 N-1 和 N-3 位置具有氨基硫脲部分,显示出最高的 α-葡萄糖苷酶抑制活性 (IC 50 = 11.42 ± 0.11 μg/ml)。
