The X‐Ray Crystal Structure of BorF, the Flavin Reductase Subunit of a Two‐Component Flavin‐Dependent Tryptophan Halogenase

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT BorF is a short‐chain flavin reductase from a desert soil bacterium that uses NADH to reduce FAD to FADH2, which is used by the tryptophan‐6‐halogenase BorH to chlorinate tryptophan in the biosynthetic pathway of borregomycin A. The X‐ray crystal structure of BorF bound to FAD was solved to 2.37 Å by molecular replacement.

Seedling resistance and chemical defenses against Psylliodes chrysocephala: the roles of seed age and sinapinic acid in Sinapis alba and Brassica napus

Pest Management Science, EarlyView.
The cabbage stem flea beetle (Psylliodes chrysocephala) is a major pest of winter oilseed rape (Brassica napus). We tested B. napus and Sinapis alba seedlings for feeding resistance and underlying chemical defenses. S. alba was least damaged, while metabolite profiles revealed resistance‐linked compounds, highlighting breeding potential for insect ...

Alcoholic extracts of Russian sage (Salvia yangii) contain bioactive terpenoids with inhibitory activity against grapevine downy mildew (Plasmopara viticola)

Pest Management Science, EarlyView.
Alcoholic extracts from flowers, leaves, and shoots of Russian sage decreased downy mildew severity on grapevine leaf disks. Fractionation followed by metabolomic analysis revealed putative terpenoids as the main components of the active fractions. Specifically, 7‐methylrosmanol, 12‐O‐methylcarnosic acid, carnosic acid, and carnosol were identified as ...

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Harnessing Natural Compounds in Psoriasis: Targeting Cellular Pathways for Effective Therapy

Phytotherapy Research, EarlyView.
Natural compounds act on key cellular pathways in psoriasis by suppressing keratinocyte hyperproliferation, modulating Th17/IL‐17‐mediated immune responses, and reducing oxidative stress. These multi‐target effects highlight their potential as safer adjunctive therapies alongside conventional treatments.
