Abstract:

Twelve novel myricetin derivatives containing acidamide moiety were designed and synthesized from myricetin. All the compounds were characterized by 1H NMR, 13C NMR and HRMS. The preliminary bioassay results indicated that all of the title compounds exhibited a certain antibacterial activities in vitro against X. oryzae, X. citri and R. solanacearum. Moreover, These title compounds 3a, 3e, 3f, 3h and 3k displayed good antibacterial activities against the above three plant pathogenic bacteria. Especially, compound 3e displayed 100% inhibition rates against X. oryzae and R. solanacearum at 200 μg/mL, respectively, which is more than the control bismerthiazol(72.85% and 75.86%, repectively).

Key words: Myricetin derivatives, Acidamide, Antibacterial activity
