Abstract: The growing inhibitory properties on Isochrysis galbana, Platymonas subcordiformis and Navicula of thirteen 2-(N-arylaminomethyl)-3-oxo-benzo[d]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.
