Imperatorin is a plant secondary metabolite belonging to the coumarins-specifically the furanocoumarins. Imperatorin enhances the GABA-induced chloride ion current (IGABA) through the α1β2γ2S receptors. Imperatorin potentiates IGABA at 100 μmol by 50.5±16.3 % and at 300 μmol by 109.8±37.7 %, respectively. Imperatorin, together with Phellopterin, found in the roots of A. dahurica, inhibit [3H]diazepam binding to the benzodiazepine site of the rat brain GABAA receptor in vitro with an IC50 of 12.3 μmol for Imperatorin and 400 nmol for Phellopterin. Imperatorin, in a concentration ranging from 3.5 to 14 mmol, significantly and irreversibly inhibits GABA-T in a time-dependent and concentration-dependent manner, by irreversibly binding with the active site of GABA-T.Imperatorin is a reversible acetylcholinesterase (AChE) inhibitor, and acts in dose-dependent manner. The AChE and BChE inhibitory activities of Imperatorin and a crude extract from the fruits of Angelica archangelica L. is tested by the spectrophotometric method at concentrations of 12.5, 25, 50, and 100 μg/mL. Imperatorin displays low inhibition towards AChE (13.75-46.11 %), whereas it has remarkable inhibitory effect against BChE (37.46-83.98 %). Imperatorin shows selectivity toward BChE rather than AChE, with an IC50 for BChE of 31.4 μmol. Imperatorin, together with (+)-Byakangelicol, are found to be the most effective BACE-1 inhibitors, with IC50s of 91.8 and 104.9 μmol, respectively. Imperatorin (IC50=9.2 μmol) is also effective as an inhibitor of NO synthesis[1]. Imperatorin is a weak agonist of TRPV1, a channel implicated in detecting several noxious stimuli, exhibiting EC50 of 12.6±3.2 μM[2].

Protocol
Mice[3]
The experiments are carried out on naive male Swiss mice weighing 20-25 g. Drugs are administered intraperitoneally (i.p.) at the volume of 10 mL/kg. Fresh drug solutions are prepared on each day of experimentation. Control groups receive saline injections of the same volume and via the same route of administration. During the acute treatment, the animals are allocated to the following drug groups: saline, rivastigmine (0.5 mg/kg, i.p.), scopolamine (1 mg/kg, i.p.), Imperatorin (1, 5, 10 mg/kg, i.p.), or Imperatorin coadministered with scopolamine. To measure the memory acquisition processes, scopolamine is administered 20 min before the pretest, whereas Imperatorin and rivastigmine are administered 30 min before the pretest. To measure the memory consolidation processes, rivastigmine or scopolamine (1 mg/kg) is administered immediately after the pretest, whereas Imperatorin is administered 15 min after pretest or after scopolamine injection. On the second day, the mice are retested. In the second set of the experiments, animals are randomly allocated to receive 6 days of i.p. injections of Imperatorin (1, 5, and 10 mg/kg, i.p.) or saline, twice daily (8:00 a.m. and 8:00 p.m.). On the seventh day, these animals are subjected to saline, scopolamine (1 mg/kg, i.p.), Imperatorin (1, 5, and 10 mg/kg, i.p.), or Imperatorin coadministered with scopolamine. To measure the memory acquisition processes, scopolamine is administered 20 min before the pretest and Imperatorin 30 min before the pretest. To measure the memory consolidation processes, scopolamine (1 mg/kg) is administered immediately after the pretest, whereas Imperatorin is administered 15 min after the pretest or after scopolamine injection. On the eighth day, the mice are retested.
