3-methyl-1-phenyl pyrazoline-5-one, cyanoacetamide and aryl- or alkylaldehydes, in the presence of catalytic amounts of triethylamine and ethanol as a solvent. All the synthesized compounds were evaluated for their inhibitory activities against butyrylcholinesterase (BChE) and bovine a-chymotrypsin. Two compounds, 8 and 9 were found to be good inhibitors of enzyme BChE with IC50 values of 52.74 ± 0
在催化量的三乙胺和乙醇作为溶剂的存在下,通过 3-甲基-1-苯基吡唑啉-5-酮、氰基乙酰胺和芳基-或烷基醛的两步反应获得了新型oxino双-吡唑。评估了所有合成的化合物对丁酰胆碱酯酶 (BChE) 和牛α-胰凝乳蛋白酶的抑制活性。发现两种化合物 8 和 9 是 BChE 酶的良好抑制剂,IC50 值分别为 52.74 ± 0.006 和 51.85 ± 0.005 μM。
