synthesized from reactions of 4 with corresponding prepared reagents via nitrile imines. Selectively, each of all isoxazole and pyrazoline derivatives was synthesized by 1,3-dipolar cycloaddition reactions of compound 4 with the corresponding reagents. Based on the results of their biological activity analyses, Ki values for acetylcholinesterase (AChE), butyrylcholinesterase (BChE), and alpha-glucosidase
在环戊二烯与4-苯基-1,2,4-三唑啉-3,5-二酮的环加成反应合成已知的加合物( 4 )后,由4与相应的苯甲醛衍生物制备的肟反应合成了7种新的异恶唑啉衍生物。在 0°C-RT 下通过腈氧化物在 CH 2 Cl 2中存在 NaOCl 水溶液。4 种新的吡唑啉衍生物也由4与相应制备的试剂通过腈亚胺反应合成。通过化合物4的 1,3-偶极环加成反应选择性地合成所有异恶唑和吡唑啉衍生物用相应的试剂。根据它们的生物活性分析结果,乙酰胆碱酯酶 (AChE)、丁酰胆碱酯酶 (BChE) 和 α-葡萄糖苷酶 (α-Gly) 酶的K i值在 32.15 ± 5.73–107.44 ± 19.52 22.57 ± 4.30– 范围内获得分别为 186.07 ± 23.51 和 69.08 ± 8.54–528.07 ± 38.46 nM。除此之外,对这些化合物进行分子对接以描述与 AChE、BChE 和 α-Gly
