The total volume was 1.0 mL and incubated at 22 ° C for 70 minutes. The test compound was dissolved in dimethyl sulfoxide (DMSO), and 4 μL thereof was added to the reaction solution so as to obtain a predetermined final concentration. After incubation, the nerve membrane fraction was collected on a GF / B glass fiber filter paper (Whatman) using a 24-well cell harvester (Brandell), and quickly 2 with 5 mL of cold (10 ° C) buffer B. Washed twice. The radioactivity of [ ³ H] EBOB bound to the membrane fraction on the filter paper was measured using a liquid scintillation counter (manufactured by Beckman) to determine the binding amount (dpm) of the test compound addition group. The group without test compound (DMSO 4 μL added) is the control group (total binding) (dpm), and the non-specific binding amount (dpm) is 1 μM of non-radioactive labeled α-endosulfan under the above conditions. Was obtained.

The specific binding amount of [ ³ H] EBOB to the membrane fraction was determined according to the following formula.
Specific binding amount (dpm) = Total binding amount (dpm)-Non-specific binding amount (dpm)
[ ³ H] EBOB specific binding inhibition degree (%) of the test compound was determined according to the following formula.
[ ³ H] EBOB specific binding inhibition (%)
= {1- (specific binding of each test compound treatment group (dpm) / specific binding of control group (dpm))} × 100
All the compounds showed an inhibitory activity of 80% or more at 10 μmol / L.

Test Example 2: Insecticidal test against cotton aphid In this example, Compound 1, Compound 5, Compound 7, Compound 8, Compound 13, Compound 14, Compound 19, Compound 21, Compound 24, Compound 25, and Compound 26 synthesized previously were used. Was used to carry out an insecticidal test against cotton aphids according to the following procedure.
A leaf disc having a diameter of 2.0 cm was cut out from the cucumber cultivated in a pot and placed in a 5.0 cm petri dish. Four adult aphids were released. One day later, the adults were removed. The number of first instar larvae born on the leaf disk was adjusted to 10 and sprayed with a chemical solution of a predetermined concentration prepared to be 50% acetone water (added with 0.05% Tween20). After air drying, the petri dish was covered and left in a constant temperature room at 25 ° C. (16 hours light period-8 hours dark period). Insects were observed for life and death 3 days after release, and the death rate was calculated according to the following formula.
Death rate (%) = {Number of dead insects / (Number of living insects tens of dead)} x 100

  All compounds showed a death rate of 40% or more at 200 ppm.

  The novel PF1198A derivative of the present invention has an excellent effect on pests and is useful as a novel pest control agent.
