DIMBOA

DIMBOA, an antibiotic, has antibacterial properties and inhibits bacteria such as Staphylococcus aureus and the mycotoxin-producing fungus Fusarium graminearum (which causes scab). DIMBOA exhibits strong free radical scavenging activity and weak iron(III) ion reducing activity, and has antioxidant activity. DIMBOA inhibits the biosynthesis and accumulation of toxic trichothecenes by affecting the expression of Tri6 and Tri5. DIMBOA reduces plant susceptibility to scab. DIMBOA also exhibits cytotoxicity to plant cells, causing plasmolysis, cell collapse, and cell rupture[1][2][3][4][5].
