Next, the pharmacological action of compound (I) will be explained. Test Example 1. Acute toxicity test A test compound was orally administered (po: 300 mg / kg) using 3 male dd strain mice each having a body weight of 20 ± 1 g per group. The mortality situation 7 days after administration was observed, and the minimum mortality (MLD) value was calculated. The results are shown in Table 2. Test Example 2. Acetylcholinesterase Inhibition Test Using rat brain homogenate as a source of acetylcholinesterase, the method of Ellman et al. [Biochem. Pha
The esterase activity was measured according to rmacol., 7 , 88 (1961)]. Acetylthiocholine, a test substance and 5,5-dithiobis (2-nitrobenzoic acid) (DTNB) were added to a rat brain homogenate as a substrate, and after incubation, the produced thiocholine reacted with DTNB to produce a yellow product at 412 nm. The acetylcholinesterase activity was determined by measuring the change in the absorbance at. The acetylcholinesterase inhibitory activity of the sample was expressed as a 50% inhibitory concentration (IC 50 ). The results are shown in Table 2.
