Natural Products Inhibit Bacterial Growth and Modulate Quorum‐Sensing Systems Las and Rhl in Pseudomonas aeruginosa PA14

Chemistry &Biodiversity, EarlyView.
ABSTRACT Quorum sensing (QS) is a bacterial cell communication system in Pseudomonas aeruginosa, which regulates the production of several virulence factors, including pyocyanin, exoproteases, and biofilm formation. Natural products (NPs) have demonstrated their ability to control QS in different bacteria. This work evaluated the antimicrobial and anti‐

Bioprospecting of Labdane‐Type Diterpenes From Austroeupatorium laetevirens: Molecular Networking, Structural Elucidation, and Biological Activity Evaluation

Chemistry &Biodiversity, EarlyView.
ABSTRACT Labdane‐type diterpenes are the main specialized metabolites in the Austroeupatorium genus, known for diverse biological activities. This study employed molecular networking to facilitate the identification of labdanes in Austroeupatorium laetevirens, alongside isolation, structural elucidation, and evaluation of anti‐Mycobacterium ...

Biochemical Responses of Anopheles spp. Larvae to a Novel Brazilian BR101 Bacillus thuringiensis var. israelensis Formulation: Oxidative Stress, Detoxification Enzymes, and Safety for Nontarget Notonectidae and Gerridae Aquatic Insects

Chemistry &Biodiversity, EarlyView.
Bti BR101 exhibits strong larvicidal activity against Anopheles larvae spp., with dose‐dependent mortality and LC50 of 3.13 µg/mL. Bti increases ROS, lipid and protein oxidation, and activates antioxidant enzymes (SOD, CAT, GPx) and detoxification pathways (MFO and esterases), indicating moderate oxidative stress.

Fe─Co Synergism in the Heterogeneous Catalytic Conversion of Cyclohexane to KA Oil

ChemCatChem, EarlyView.
This research aimed to investigate the potential of heterogeneous Fe‐Co catalysts supported on Alumina in the oxidation of cyclohexane to cyclohexanol and cyclohexanone (KA oil). Different catalysts have been synthesized by sol‐immobilization, wetness impregnation and inverse microemulsion, revealing a different catalytic activity and selectivity ...
