Abstract—Plant defense responses to herbivore attack and mechanical wounding are regulated by signal transduction pathways. Jasmonates (JAs) are important signal mediators that involve in plant defense signaling. To explore the regulation mechanism of JAs signaling, we have been working on JA biosynthesis inhibitors through design and synthesis small molecules targeting allene oxide synthase (AOS, CYP74A), a key enzyme in JA biosynthesis. In the present work, we report the synthesis of new imidazole-type AOS inhibitors based on ozagrel scaffold. The inhibitory activity of the synthesized compounds against AOS was determined by using purified recombinant protein expressed in E. Coli. Among the nine newly synthesized imidazole derivatives, we found that 6-[4-(2-imidazol-1-yl-ethyl) phenoxy] hexanoic acid ethyl ester (f) exhibits inhibitory activity against AOS with an IC50 value approximately 78±12µM.
