Abstract: Dimethylaminoethyl 2-, 3-, and 4-alkoxyphenylcarbamates (n-alkoxy = methoxy to decyloxy) inhibit photosynthetic processes in algae and plant chloroplasts. The inhibitory activity of studied compounds shows a significant increase with the prolongation of the alkyl chain of the substituent and is suppressed only at derivatives with longer (C₈-C₁₀) alkoxy substituent. The inhibitory activity of 2-substituted derivatives is lower than that of their 3- and 4-substituted analogues. The most effective compounds exhibit algicidal effects at concentration 6 x 10^-6 mol dm^-3.
