Extract from Maize (Zea mays L.): Antibacterial Activity of DIMBOA and Its Derivatives against Ralstonia solanacearum.
Many cereals accumulate hydroxamic acids involved in defense of plant against various fungi, bacteria, and insects. 2,4-dihydroxy-7-methoxy-1,4-benzoxazine-3-one, commonly known as DIMBOA, is one of the principal cyclic hydroxamic acids in aqueous extracts of maize. The aim of this study was to evaluate the antibacterial activity of the isolated DIMBOA and its derivatives 2-benzoxazolinone (BOA...
متن کاملNew Insights into the Antibacterial Activity of Hydroxycoumarins against Ralstonia solanacearum.
Coumarins are important plant-derived natural products with wide-ranging bioactivities and extensive applications. In this study, we evaluated for the first time the antibacterial activity and mechanisms of action of coumarins against the phytopathogen Ralstonia solanacearum, and investigated the effect of functional group substitution. We first tested the antibacterial activity of 18 plant-der...
متن کاملSynthesis and antibacterial activity against ralstonia solanacearum for novel hydrazone derivatives containing a pyridine moiety
BACKGROUND Ralstonia solanacearum, one of the most important bacterial diseases on plants, is a devastating, soil-borne plant pathogen with a global distribution and an unusually wide host range. In order to discover new bioactive molecules and pesticides acting on tobacco bacterial wilt, we sought to combine the active structure of hydrazone and pyridine together to design and synthesize a ser...
متن کاملMolecular Diversity of Ralstonia solanacearum Isolated from Ginger in Hawaii.
ABSTRACT The genetic diversity of Ralstonia solanacearum strains isolated from ginger (Zingiber officinale) growing on the island of Hawaii was determined by analysis of amplified fragment length polymorphisms (AFLPs). Initially 28 strains of R. solanacearum collected from five host plant species worldwide were analyzed by AFLP. A second analysis was conducted on 55 R. solanacearum strains coll...
متن کاملAntibacterial activity of the flavonoids from Dalbergia odorifera on Ralstonia solanacearum.
Phytohemical investigation on the heartwood of Dalbergia odorifera resulted in the isolation of nine flavonoids. Their structures were elucidated as sativanone (1), (3R)-vestitone (2), (3R)-2',3',7-trihydroxy-4'-methoxyisoflavanone (3), (3R)-4'-methoxy-2',3,7-trihydroxyisoflavanone (4), carthamidin (5), liquiritigenin (6), isoliquiritigenin (7), (3R)-vestitol (8), and sulfuretin (9) based on th...
