To develop novel antiviral agents, some novel conjugates between ferulic acid and eugenol or isoeugenol were designed and synthesized by the link reaction. The antiviral activities of compounds were evaluated using the half leaf dead spot method. Bioassay results showed acceptable antiviral activities of some conjugates against the tobacco mosaic virus (TMV) and cucumber mosaic virus (CMV). Compounds A9, A10, E1, and E4 showed remarkable curative, protective, and inactivating effects on TMV and CMV at 500 μg mL-1. Notably, these compounds exhibited excellent protective effects on TMV and CMV. The EC50 values of compounds A9, A10, E1, and E4 against TMV were 180.5, 169.5, 211.4, and 135.5 μg mL-1, respectively, and those against CMV were 210.5, 239.1, 218.4, and 178.6 μg mL-1, respectively, which were superior to those of ferulic acid (471.5 and 489.2 μg mL-1), eugenol (456.3 and 463.2 μg mL-1), isoeugenol (478.4 and 487.5 μg mL-1), and ningnanmycin (246.5 and 286.6 μg mL-1). Then, the antiviral mechanisms of compound E4 were investigated by determining defensive enzyme activities and multi-omics analysis. The results indicated that compound E4 resisted the virus infection by enhancing defensive responses via inducing the accumulation of secondary metabolites from the phenylpropanoid biosynthesis pathway in tobacco.
Novel trans-Ferulic Acid Derivatives Containing a Chalcone Moiety as Potential Activator for Plant Resistance Induction

A series of novel trans-ferulic acid derivatives containing a chalcone moiety were designed and synthesized to induce plant resistance. Antiviral activities of the compounds were evaluated. Bioassay results demonstrated that compounds F3, F6, F17, and F27 showed remarkable curative, protective, and inactivating activities against tobacco mosaic virus (TMV). With a 50% effective concentration (EC50) value of 98.78 μg mL-1, compound F27 exhibited the best protective activity compared with trans-ferulic acid (328.6 μg mL-1), dufulin (385.6 μg mL-1), and ningnanmycin (241.3 μg mL-1). This protective ability was associated with potentiation of defense-related enzyme activity and activation of photosynthesis of tobacco at an early stage. This notion was confirmed by up-regulated expression of stress responses and photosynthesis regulating proteins. This work revealed that F27 can induce resistance and enhance plant tolerance to TMV infection. Hence, F27 can be considered as a novel activator for inducing plant resistance.
