Abstract: 2-Styrylbenzothiazolium salts substituted at the position 3 were prepared by alkylation of 2-styrylbenzothiazole with methyl iodide, dimethyl sulfate, allyl bromide, propargyl bromide, benzyl bromide, bromoacetic acid, and bromoacetic acid esters. Their structure was proved by UV, IR, and IH NMR spectra. The compounds showed the activity as plant-growth regulators, and affected both the cells division of Euglena gracilis and the synthesis of chlorophyll. The antibacterial and antifungal activities were also found.
