The invention discloses a lignan compound of which the structure is selected from one of the following structures: the lignan compound prepared by the invention has a remarkable inhibition effect on the activity of butyrylcholine esterase, and the binding free energy of the two lignan compounds and BChE is analyzed by performing molecular docking on the two lignan compounds and the butyrylcholine esterase. A molecular docking result proves a butyrylcholine esterase activity in-vitro inhibition experiment result, so that the lignan compound prepared by the invention has huge potential as a butyrylcholine esterase inhibitor.

The application provides an organic phosphorus poisoning relief composite enzyme and application thereof, and belongs to the technical field of biological medicine. The organic phosphorus poisoning relief composite enzyme provided by the application comprises polyethylene glycol modified organic phosphorus hydrolase and butyrylcholine esterase, and the mass ratio of the polyethylene glycol modified organic phosphorus hydrolase to the butyrylcholine esterase is (4-8):(2500-10000). The rat acute organic phosphorus poisoning treatment result shows that the organic phosphorus poisoning relief composite enzyme provided by the application fully plays the efficient catalytic hydrolysis capacity of the enzyme as a catalyst, efficiently removes organic phosphorus and acetylcholine by using the organic phosphorus hydrolase and the butyrylcholine esterase respectively, provides a drug combination for treating the cause for the organic phosphorus poisoning injury first aid, and the treatment effect is significantly better than that of the single drug.
