2-(N-芳基氨甲基)苯并异噻唑啉酮类化合物对海洋浮游生物的生长抑制活性研究

本文研究了13个2-(N-芳基氨甲基)苯并异噻唑啉-3-酮类化合物对球等鞭金藻Isochrysis galbana、亚心形扁藻Platymonas subcordiformis及舟形藻Navicula的生长抑制性能,并测试了其对藤壶二期无节幼虫的生物活性。结果表明:2-(N-芳基氨甲基)苯并异噻唑啉-3-酮类化合物对球等鞭金藻、亚心形扁藻和舟形藻都有良好的生长抑制活性,其中对球等鞭金藻和亚心形扁藻的抑制作用较强;对藤壶幼虫的生物活性测试表明,化合物最低质量浓度为2.0 mg/L时,除化合物g和l,都具有良好的生长抑制活性。化合物的结构与浮游生物的生长抑制活性关系表现为间位取代优于对位取代。

The inhibitory activities of marine plankton by 2-(N-arylaminomethyl)-3-oxo-benzo[d]isothiazoles

The growing inhibitory properties on Isochrysis galbana, Platymonas subcordiformis and Navicula of thirteen 2-(N-arylaminomethyl)-3-oxo-benzod]isothiazoles were investigated, and the effects on biological activity of barnacle nauplii were also studied. The results indicate that the tested compounds have favourable growing inhibitory activities to the marine algas, and the better inhibitory activities are on Isochrysis galbana and Platymonas subcordiformis. The results also indicate when the lowest concentration is 2.0 mg/L, the tested compounds show a favourable growing inhibitory activity on barnacle larvae except the compound g and l. The relationship between compounds' structure and plankton growth inhibitory activity reveals that meta-substituent is better than para-substituent.
