A series of sulfonamide derivatives were synthesized by  reactions with various functional groups containing benzenesulfonyl  chlorides and aniline derivatives under different substitution reaction  conditions. The structures of SMZ derivatives were confirmed with melting  point, FT-IR, $^1}$H NMR, $^13}$C NMR, and LC-MS/MS techniques. In order  to investigate the cytotoxic effects of these derivatives, we used a model  plant species. The synthesized compounds (S1-S5) and  sulfamethazine (SMZ) as a positive control were applied to Arabidopsis thaliana seeds. Our  results indicated that S3 and S4 induced shorter roots and  lower wet weight in plants. Plants treated with S2 and  S5 showed no growth effects, similar to the untreated control group, while  S1 slightly reduced root length and wet weight. These results  suggest that S3 and the newly synthesized S4  derivatives have potential for use as herbicides since they possess  cytotoxic effects on A. thaliana plants.
