摘要
合成了33个苯并噻唑和苯并噻二唑类化合物,所有新化合物经过元素分析、1HNMR和IR确认,初步的离体生物活性结果表明:I-09、II-01、II-05、II-06、III-01、III-03和III-05的活性较好,对黄瓜灰霉病菌具有良好的抑制作用。活体抗菌诱导生物活性测定结果表明:I-04、I-07、II-09、II-13、III-02、III-071000mg/L在离体条件下对黄瓜灰霉病没有抑制作用,在活体条件下有一定的抑制作用,抑制率在55.0%￣84.4%,表明具有良好的诱导抗性活性。
Thirty two new benzothiadiazole and benzothiazole derives were prepared. The structures were confirmed by elemental analysis, IH NMR and IR, The preliminary hioassay showed that the compounds 1-09, II-01, II-05, II-06, III-01, III-03 and III-05 had good fungicidal activities against Botrytis cinerea in vitro. The compounds I-04, 1-07, II-09, II-13, III-02 and III-07 had no inhabitation against Botrytis cinerea in vitro, but they had some activity with 55.0 to 84.4% inhabitation in vivo. The result showed that some compounds had induced resistance activities in vivo.
