Cationic derivatives of the plant resistance inducer benzo[1,2,3]thiadiazole-7-carbothioic acid S-methyl ester (BTH) as bifunctional ionic liquids

We have synthesized, new salt derivatives of benzo[1,2,3]thiadiazole-7-carbothioic acid S-methyl ester (BTH) containing BTH as the cation in combination with anions, which modify the physical and antibacterial properties of the resulting product while preserving the systemic acquired resistance (SAR) induction properties. The obtained compounds were tested toward induction of resistance in tobacco (Nicotiana tabacum var. Xanthi), which was later infected with OLV-1 and TMV viruses. Moreover in vitro tests on bacteria confirmed the preservation of antibacterial properties brought about by a docusate anion.
