Phytochemical Investigation and Biological Evaluation of Disynaphia filifolia: A Novel Source of Tremetone in Asteraceae

Chemistry &Biodiversity, EarlyView.
ABSTRACT Chemical investigation of Disynaphia filifolia (Hassl.) R.M. King & H. Rob. (Asteraceae) led to the isolation of eight compounds, with tremetone being the major metabolite recovered. Tremetone has been suggested as the toxic compound in Ageratina altissima and Isocoma pluriflora, two species of the Asteraceae family. Although D.

In Vivo Biosynthesis and Direct Incorporation of Non‐Canonical Amino Acids into Proteins

ChemBioChem, Accepted Article.
Autonomous cells are engineered biological systems capable of biosynthesising and directly incorporating non‐canonical amino acids (ncAAs) into proteins. These systems have the potential to extend the applicability of the genetic code to enable large‐scale fermentative production of proteins carrying ncAAs.

FabR regulates Salmonella biofilm formation via its direct target FabB [PDF]

, 2016
Background: Biofilm formation is an important survival strategy of Salmonella in all environments. By mutant screening, we showed a knock-out mutant of fabR, encoding a repressor of unsaturated fatty acid biosynthesis (UFA), to have impaired biofilm ...

Hijacking the Electron Train: Menaquinone‐Binding Antimicrobial Peptides

ChemBioChem, EarlyView.
Menaquinone is an emerging target for antimicrobial peptides. Could it be the new Achilles’ Heel of bacteria? The rise of antibiotic resistance threatens to undermine modern medicine, making the development of new antibiotics and novel targets an urgent priority.

Salmonella serovars in laying hen flocks and commercial table eggs from a region of São Paulo state, Brazil

Brazilian Journal of Poultry Science, 2014
Salmonella spp. is the main originator of human foodborne diseases worldwide and is mainly transmitted by food containing eggs. In Brazil, as a result of the lack of studies and data collection very little is known about the prevalence of Salmonella spp.
