Zusammenfassung:N-Dimethoxyphosphinothionyl carbofuran, PSC, has a high insecticidal activity and low mammalian toxicity. Ten N-phosphinothionyl carbofuran derivatives were synthesized and their insecticidal activities were determined against brown plant hopper (Nilaparvata lugens), green peach aphid (Myzus persicae), diamondback moth (Plutella xylostella), and two-spotted spider mite (Tetranychus urticae). Green peach aphid, diamondback mea and brown plant hopper were controlled over 90% by application of 125 ppm, 125 ppm, and 63 ppm, respectively, of carbosulfan. Two hundred and fifty ppm of newly synthesized compounds could control most of brown plant hopper and diamondback moth. Especially, insecticidal activities of compound 10 against brown plant hopper, diamondback moth, and green peach aphid were similar to those of carbosulfan. Our results show that the newly synthesized derivatives of NV-phosphinothionyl carbofuran have a similar insecticidal activity to carbosulfan. N-Dimethoxyphosphinothioyl carbofuran(PSC)는 대부분의 해충과 포유동물에 대하여 뛰어난 선택독성을 갖지만 몇몇 해충에 대해서는 낮은 살충력을 갖는다. PSC에 N-phosphinocioyl 기를 도입하여 10종의 N-phosphinothioyl carbofuran 유도체를 합성하였고, 이들의 살충활성을 벼멸구(brown plant hopper, Nilaparvata lugens), 복숭아혹진딧물(green peach aphid, Myzus persicae), 배추좀나방(diamondback moth, Plutella xylostella)와 두점박이응애 (two-spotted spider mite, Tetranychus urticae)를 대상으로 검정하였다. 대조약제인 carbosulfan의 경우 125 ppm, 125 ppm과 63 ppm 처리시 각각 복숭아혹진딧물, 배추좀나방과 벼멸구에 대하여 90% 이상의 살충활성을 나타내었다. 신규 합성된 대부분의 화합물들은 250 ppm 처리시 배추좀나방과 벼멸구에 대하여 공히 90% 이상의 살충활성을 나타내었다. 특히 화합물 10은 복숭아혹진딧물, 배추좀나방과 벼멸구를 각각 125 ppm, 125 ppm과 31 ppm에서 90% 이상 치사시켰는데, 이러한 화합물 10의 살충효과는 carbosulfan의 살충효과와 비슷한 것이었다. 본 실험의 결과는 N-phosphinothioyl carbofuran 유도체들이 새로운 살충제 개발을 위한 선도물질로 이용될 수 있다는 것을 시사한다.
