摘要: 采用结构拼接法设计合成了4-三氟乙酰-3-甲基-1-苯基-5-吡唑啉酮缩γ-氨基丁酸(L1)、1-苯基-3-甲基-4-苯甲酰基-5-吡唑啉酮缩γ-氨基丁酸(L2)两种新配体,以及两个配体的Ca、Zn配合物。采用红外分光光度法和紫外分光光度法对合成的6种化合物进行了结构表征,采用MTT法测定了6种化合物对白玉菇菌丝脱氢酶活性的影响。结果表明:6种化合物对白玉菇菌丝脱氢酶的活性均有抑制作用,其中配体L2对白玉菇菌丝脱氢酶活性的抑制能力最强,配体L1最差;采用分子对接法研究了菌丝脱氢酶与原始配体泛醌,以及配体L1和L2的相互作用,发现两个新配体与菌丝脱氢酶的结合能力均好于原始配体泛醌,且配体L2好于配体L1。该结果与MTT试验结果一致,说明配体L1和配体L2可能是通过与泛醌进行结合竞争表现出对琥珀酸脱氢酶的抑制活性。

Abstract: A new ligand(L1)derived from γ-aminobutyric acid and 4-trifluoroacetyl-3- methyl-1-phenyl-5-pyrazolone, and a new ligand(L2)derived from γ-aminobutyric acid and 1-phenyl-3-methyl-4-benzoyl-5-pyrazolone were synthesized and characterized by IR and UV, so did their Ca, Zn complexes. The inhibititted effect of the compounds on the mycelium dehydrogenase activity of Hypsizygus marmoreus was determined by MTT methods. The results showed that ligand L2 had stronger inhibitition ability to mycelium dehydrogenase while ligand L1 was the weaker. Molecular docking method was used to analysize the interaction of the mycelium dehydrogenase and the ligands. The results suggested that the two new ligands showed higher interactions to mycelium dehydrogenase than original ubiquinone, and ligand L2 showed higher interactions to mycelium dehydrogenase than ligand L1.
