Several types of jasomonic acid (JA) derivatives, including JA-amino acid conjugates, a JA-biotin conjugate, a JA-dexamethasone heterodimer, and a JA-fluoresceine conjugate, were prepared as candidates for molecular probes to identify JA-binding proteins. These JA derivatives, excepting the JA-fluoresceine conjugate, exhibited significant biological activities in a rice seedling assay, a rice phytoalexin-inducing assay, and/or a soybean phenylalanine ammonia-lyase-inducing assay. These JA derivatives could therefore be useful probes for identifying JA-binding proteins. The activity spectra of the prepared compounds were different from each other, suggesting that different types of JA receptors were involved in the perception of JA derivatives in the respective bioassays.

Both racemic jasmonic acid and the naturally occurring (-)-enantiomer have been reacted with aliphatic, aromatic as well as acidic amino acids to form amide-linked derivatives.The diastereoisomeric products of (+/-)-jasmonic acid with S-Val, S-Leu, S-Ile, S-Phe, S-Trp, R-Val, and R-Phe could be separated by silica gel chromatography.The synthesized N-(jasmonoyl)-conjugates have been structurally characterized by MS, (1)H NMR, IR and ORD.
