Inhibition of aflatoxin biosynthesis by phenolic compounds.
The phenolic compounds acetosyringone, syringaldehyde and sinapinic acid inhibited the biosynthesis of aflatoxin B1 (AFB1) by A. flavus. Acetosyringone was the most active among the three compounds, inhibiting aflatoxin level by 82% at 2 m moll-1. The synthesis and accumulation of norsolorinic acid, an aflatoxin biosynthetic intermediate, was also inhibited. These results suggest that at least ...
متن کاملBacterial Neuraminidase Rescues Influenza Virus Replication from Inhibition by a Neuraminidase Inhibitor
Influenza virus neuraminidase (NA) cleaves terminal sialic acid residues on oligosaccharide chains that are receptors for virus binding, thus playing an important role in the release of virions from infected cells to promote the spread of cell-to-cell infection. In addition, NA plays a role at the initial stage of viral infection in the respiratory tract by degrading hemagglutination inhibitors...
متن کاملThree New Non-reducing Polyketide Synthase Genes from the Lichen-Forming Fungus Usnea longissima
Usnea longissima has a long history of use as a traditional medicine. Several bioactive compounds, primarily belonging to the polyketide family, have been isolated from U. longissima. However, the genes for the biosynthesis of these compounds are yet to be identified. In the present study, three different types of non-reducing polyketide synthases (UlPKS2, UlPKS4, and UlPKS6) were identified fr...

متن کاملSecondary Metabolites Identification From Lichen Usnea longissima Ach. : Bioactivity Test of Antibacterial
Isolation and identification of secondary metabolite compound from chloroform fraction of Usnea longissima and its bioactivity test as an antibacterial had been conducted. The isolation of the chemical compound was performed by using Gravity Column Chromatography (GCC) and ThinLayered Chromatography (TLC). The result showed the needle crystal shaped isolated compound with translucent white colo...
