[Molecular pharmacological investigation of medicinal plant substances. II. Inhibition of acetylcholinesterase by monoterpene derivatives in vitro].

Monoterpene derivatives with spasmolytic activity inhibited acetylcholinesterase (ACHE, EC 3.1.1.7) in a dose dependent manner in vitro. The median inhibitory concentrations ranges between 10(-4) M and 10(-2) M. A significance of our finding may be the possible explanation of effects of monoterpene derivatives seen in distony of digestive tract.
