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.
