3-Indolepropionic acid (IPA)-related compounds having a benzo[b]thiophene or an indazole ring andderivatives having various substituents in the propionic acid moieties were tested for theirantibacterial activity against Ralstonia solanacearum. Substitution of the indole ring for otheraromatic rings resulted in lowered activity, whereas addition of a methyl or a trifluoromethyl groupto the propionic acid moiety had little effect. Of the derivatives, 3-(3-indolyl)butanoic acid (3-IBA)was as active as IPA, exhibiting a 10-fold higher activity with the S configuration than with the Rconfiguration. In contrast with the strong phytotoxicity of IPA, 3-IBA was able to suppress bacterialwilt without affecting the growth of tomato plants.Keywords: 3-Indolepropionic acid; 3-(3-indolyl)butanoic acid; Ralstonia solanacearum; bacterialwilt; tomato plants
